PCjs Machines

Have your computer turn your lights and appliances on and off!  Build
yourself a computerized home.

Someday all homes will be intelligent.  You can get on-board now with
the HOME CONTROL PRIMER, an excellent introduction to home automation.
Light and appliance control is accomplished by using the X-10
Powerhouse Computer Interface. The HOME CONTROL PRIMER consists of three
independent programs:

~ SENDX10 turns lights and appliances on/off from the DOS command line
or from batch files.

~ SYNCHX10 synchronizes the clock inside the X-10 Powerhouse Computer
Interface with that of your PC.

~ GAMEPORT explores the analog and digital input capabilities of the PC
gameport.  The Game Port Monitor lets you hook up sensors to your PC's
game port so you can begin to experiment with environment monitoring.
You can measure light intensity in a room, monitor windows and doors,
measure temperature, and observe human movement through open spaces.

Taken together, these programs will teach you the fundamentals of
computerized home control.  Move your home into the 21st Century today!

Dear Steve

Are the "Plug 'N Power" modules sold by Radio Shack the
same as the BSR modules you condemned in your July '83 article
"Build the RTC-4 Real-Time Controller", or have they remedied
the problems.

I have a need to control 20+ lamps/appliances in association
with a home security/convenience system at my parents
residence.  Things like the pump to their solar-heated swimming
pool (sounds like the typical California stereotype doesn't it...),
the sprinkler system, etc can all be run with a simple on/off
control.  As for the "Plug 'N Power" modules,  they're a lot easier
to use than running wires with relays, but I don't enjoy throwing
money away either!

So how 'bout it, Steve.  Are these things any better 5 years
later?

Thanks!!

If you will look at the current Radio Shack flyer, they are selling a toy to 
control BSR/X-10 modules.  There is now a company X-10 Ltd. that is the 
division of BSR that makes any BSR "approved" module.
As I understand it, RS bought this gadget from GE who had it built to their 
specs by X-10 before GE got out of the market. It looks like it will do what 
you need.

BSR is no longer in the module business.  A group of employees bought out the 
business and the company is called X-10 (USA) Ltd. X-10 makes all the modules 
and controllers that are private labeled and sold by companies like Radio 
Shack, Sears, Stanley, and so on.

I did see that Radio Shack bought out GE's HomeMinder and is offering it in 
their latest catalog.  Looks like a good deal.

By the way, all the reports of false triggering and reliability problems with 
X-10 modules during the past few years have been corrected in the redesigned 
versions of the modules.  The old modules were mostly brown and had the house 
code and module number dials on the sides of the module.  Those were the flakey
ones.  The new modules are mostly ivory and require a screwdriver to set the 
codes.  They are completely redesigned and very reliable.  A look inside 
reveals marked improvements from the old design to the new.

Ken,
I wanted some info on the new modules and after a bunch of phone calls I was 
able to talk to one of their engineering managers.   He told me that X-10 was a
us}  US subsidary of BSR, ltd.  But what your saying may be the }ireal story.

I went ahead and bought one of the Homeminder toys.  Its kinda neat.  The cpu 
board is sealed up in soldered box and all I could see through holes in the top
was a z80 cpu.   Wish I knew what video chip they were using.
thanks

Apparently the new X-10 modules are better than the old ones (they seem about 
the same in my experience, however).

Regarding the X-10 computer interface, it can be connected to any  computer 
that has one input and one output bit (a parallel printer port will do). You 
merely send it TTL data which it transmits to the AC line. If you subscribe to 
INK now you won't miss it. 

To my knowlege, I believe Ken already has the transmitter running on the 
BCC-180. The only thing holding up the article right now is X-10. They are 
upset about how much detail I want to devulge about their system and they don't
want me to build and X-10 command receiver (which is the companion article). 
I'm still negotiating.

Believe it or not, I proposed this $30 X-10 interface to BYTE and they didn't 
want it. They (the editor in chief, that is) said it wasn't in  the best 
interest of their audience (maybe they have been writing to a different group 
than I have). I should be looking at articles (mind you, not projects) that 
have a broader appeal.

The "Homeminder" is GE's failed attempt at what they called a "Home Control 
System".  It orginally retailed for something like $400 back in 1984.  Radio 
Shack got their hands on the thousands sitting in the warehouse and did a slick
job of reworking them.  They covered over all the GE labels with theirs, 
rewrote the manual with their name on top and even made a brand new box to hold
the system in.  All this for $60 is a pretty good deal!  I had to buy one just 
to say that I had the first attempt at Home Control by a huge consumer 
electronics giant!  You should have seen the look my wife gave me when she saw 
me take the thing out of the box (brand new) and proceed to rip all the Radio 
Shack labels off of it!  Oh well, living with a certified electronics kook, she
is used to  seeing me rip apart brand new "toys".  In any event, the point I 
wanted to make is that wouldn't it be ironic if the first failed attempt at 
Home Control by a major company turns into the first mass market home control 
success by another major company (the Shack).  I think the price is what kept 
people away from products like this in the first place!  Enough of the soapbox.
I really wanted to make my first message on the new system a really LONG ONE so
I could give this thing a good test.  I love the new FAST RESPONSE of this 
system.

Jeff, While the radio shack homeminder has some neat features the home control 
system provided by Steve's byte article some time ago is quite a bit more 
flexible than the homeminder.  I am currently using one with about 22  modules 
to control most of the lights in my home.Several are turned on by presence. ( a
passive ir detector sees you and the HCS turns the light on).  I have been very
pleased with the reliability of the HCS and the relative ease of use.

Jeff, I have been tinkering with the BSR controller stuff for several years. I 
have not found the units to particularly un predictable. I did at first  and 
spent a considerable amount of time researching carrier current operation 
techniques. My research on this actually started back in college where I ran 
the campus radio station on carrier current. The units, transmitters or 
receivers are sensitive to line impedence changes particularly between phases 
of the 240/110 VAC line. This can be overcome with a couple of tricks. I have 
recently completed and am working on rev 2 of a stereo control interface which 
is controlled by the BSR carrier signals (ie. I acn control my stereo from 
anywhere there is a controller or a computer with BSR output capabilities). 
Would love to talk about this home control stuff all day but in closing let me 
say I puschased one of the Radio Shack/GE HOME MINDER. I think it's a neat box.

the micro portion to run on battery on power failure, while the modem chip will
be powered by AC only. Obviously I can't just have that chip on the buss but 
would something like anding the inputs to the output enable of a buss interface
chip, with the processor control line and a 5 volt line powered from the AC

There's freedom of the press and reality. Sure, I can publish anything I want 
but if I care that the info is to be use by the readers, its best that I don't 
do it without the blessing of the company that manufactures the stuff that I 
use in the article. Unfortunately, X-10 is paranoid. They think that every time
I tell anybody what's in their little boxes that the whole world is going to 
rip off their design and put them out of business (perhaps this should be an 
indication of just how solid their patent really is). I have an X-10 
transmitter interface article planned for a future issue of INK (BYTE doesn't 
want anything that reeks of home control anymore). The transmitter is made by 
X-10 and the article would be on interfacing it to various computers. I also 
plan a companion 120 KHz AC line receiver article that would allow full duplex 
AC line communication as well as control. X-10 is adamantly against me 
presenting any kind of a receiver and is screaming patents/law suit if I tell 
you how to make a stinking 120 KHz AC line receiver. Well, I'm not thrilled 
with anyone telling me what I can't do so we'll see about that. Unfortunately, 
I want the device that they plan to manufacture (the transmitter) if I P____ 
them off then anyone reading the project will have trouble getting it. Instead,
I wish that a few of you guys would write to Dave Rye at X-10 (hey Ken. You got
an address?) and suggest that my writing article enhances their sales. BYTE and
these guys are all making a big mistake again. They think that "hacker" means 
dumb and no money. But, what do you expect from people who never correspond

It would seem to me that X-10's main source of income is from selling the 
little receiver modules by the zillions and not by selling transmitters.  Any 
OEM that puts an X-10 transmitter in their product is automatically going to 
stimulate alot of sales of receiver modules.  It would take a mega company, 
like Black & Decker, to compete with X-10 on receiver modules and not Ciarcia 
or Micromint.  I've spoken with the folks at X-10 along these lines in the past
year and I really think they miss the boat.  The first really good mass 
marketed Home Control System is going to have and X-10 transmitter in it and 
possibly even an X-10 receiver to process messages as well.  X-10 will probably
want to sue the maker, but will look pretty ridiculous if thousands of their 
receiver modules are sold because of it.

disassembled one of them about 5 years ago). Their later inteface (also made by
BSR) could be programmed by the host computer like a VCR and then left to

I know Steve never mentioned it and I doubt it would have been in any other 
BYTE articles.  X-10 makes a serial-based computer interface with some smarts 
in it.  You buy it with software written for a specific computer.  Using that 
software, you program events based on time-of-day and send that list to the box
serially.  Once programmed, you unplug the host computer and the interface 
stands alone.  You can also write your own software to talk to the interface 
and not use X-10's software.  That way, you can use it with any computer that 
has a serial port capable of running 600 baud.

I've seen the interface for sale at most places that sell modules (except Radio
Shack).  DAK and Heathkit are two that come to mind.

something. I had planned to present a X-10 (BSR) code receiver as part of the 
INK transmiter project. When X-10 found out about it (I told them) they went 
B___S__T !  They started screaming about patent violations and junk about using
their codes and especially zero crossing transmission and reception as theirs. 
Now we all know that I can publish anything I damn well please, patented or 
not, but I usually try to have the more popular stuff manufactured as kits. A 
legal shootout with them would have eliminated manufacturing anything and left 
an audience primed for something I can't deliver. 

In exchange for NOT messing up their market right now, CCI will have access to 
the new X-10 transmitter module that will undoubtedly hard to get and we'll 
have a good project. After the dust settles, we'll check their patent and see 
about that stuff. Just becareful that you aren't X-10 test case for holding

Never the less, I believe the actual control portion of my design

my decoder circuits with BSR's chips (it would actually reduce the chip count

I believe you have a right to use and publish any technology (not deeemed as 
classified, at least) you want. You can still write an article and if it is 
well written and offers something useful to the CC INK readers, it will be 
published. Only if you manufacture something receiving X-10 codes will I expect
that the X-10 people will get excited (the key word is manufacture). They got 
concerned when i told them I was presenting a receiver because I have a history
of licensing my designs for manufacture and because they remember that 2 
articles that I did back in '76 and '77 virtually created their market for 
them. I guess they don't know whether to love or hate me. :-)

Yess Ken is right the best way is to call Micromint (203-871-6170) and ask for 
a series manual set. For the BCC11 (Z8), the package is called the BCC99/11 for
$39. Similarily, for the BCC52 (8052) it is the BCC99/52 and it is also #39. 
There are about a dozen manuals in each set including all manufacturer doc 
(Zilog Z8 manual or BASIC-52) is included where necessary. Finally, a new 
manual set is being readied for the BCC180 (64180) called the BCC99/180. It 
includes not only the appropriate BCC expansion board manuals with the BCC180 
user's manual, but also the all the SB180 stuff and BASIC-180 doc (200 pages 
alone). This one weighs POUNDS and costs $59. If you ever wanted to build any 
of this hardware, these manual sets are the way to go.

I'm fairly new to hardware design (good at putting them together though) and 
need to get some info... Im trying to finish the design of my parents house 
(just recieved my degree in architectural design). They have 2 amiga computers 
and an old RS model 3. My questions come in that they want an automated house 
with BSR type controls and a survailance/security system all computer 
controled. Also my father has 4 video machines (2 beta 1 vhs and a Vid -8) plus
cable etc...so an AVMUX would be perfect for his Audio Video dreams (you should
have seen the mess of AB selector and wires befor I moved out) I would like to 
control all of this through one of the Amiga computers (one 1000 the other a 
2000) or maybe a better route have them controlled by a BCC52 or SB180 with a 
serial link to the Amiga. Any suggestions ??? Also how long of a run would the 
AVMUX drive before signal noise/loss started taking an appreciable toll ?
Thanks 
:)   Eric

PS -- Any good books to actually teach  myself about hardware design (theory ) 
I have learned a bit by reading Byte and on this board just observing.

You have quite a list of goals there :-) , but I suppose you wouldn't have 
asked if you were an electrical engineer like most of the rest of us. Education
and experimentation is the route to achieving your goal. There is no single 
source book that will teach you to be a designer. That ability comes from many 
sources and takes time. Most of us just started reading a bunch of magazines 
and communicating with other people with similar interests.  Sounds like you've
done that much but it might be advisible to sit down with someone who knows 
your background and interests in more detail to plot the right future course. 
Regarding the AVMUX (which seems to be of continued interest. Perhaps it's time
to design a new one.), I am driving 25' cables and it seems OK but  it depends 
upon the termination impedance (what you have it connected to).

Well -- glad to see another Amiga user interested in hardware!  For starters, 
you might consider abandoning any hardwired approach to coupling the amiga to 
the avmux and/or the bsr type modules.  I think there's a controller that 
accepts touch tones as inputs.  The Amiga can *easily* produce touch-tone 
frequencies, with which you can control the bsr modules, and perhaps thereby 
the avmux.  A letter to the editor in AmigaWorld listed the proper frequencies 
to use in AmigaBasic.  I wrote a small program to dial my telephone using those
frequencies, and it worked fine.  This way, your parents could also use their 
radio telephone as a controller!

I'll look it up and leave another message.  I've designed a parallel port 
expander for the Amiga, using a 8255 chip.  It allows up to about 256 parallel 
ports to be added.  I've written a preliminary softward driver for it, but have
yet to actually construct the board.  It attaches to the existing parallel 
port, so high speed transfer among all ports is definately limited.  I designed
it to make a 68701 programmer, though, so speed is not one of my concerns. A 
hardware solution is much better.  I have the Micron 2 meg expansion board with
my A1000. I got the powered 2 slot chassis, and so have one extra slot.  I hope
to have some neat boards to drop in there.  Maybe yours when its finished!

I wouldn't think you would need to re-write the parallel.device, but if so you 
could probably disassemble the existing device and modify it to work.  I know 
there's been a lot of talk on bix and the like to add extra serial ports, so I 
think it's possible. By the way, the AmigaWorld issue you want for the 
touchtone frequencies is Sept/Oct '87.  Also, the last Amazing computing

One of the most parenoid companies I have ever dealt with is X-10. I don't have

it easy to obtain. The only reaso they are making this new X-10 line 
transmitter and circulating its schematic is that it is a case of "if you can't
beat 'em, join 'em". X-10 saw everyone (including us) using X-10 codes in 
products. Now they say that you have to use their OEM line transmitter or they 
will sue for violating their patents. Personally, I think it's a crock but the

Thank you Steve.  I guess I was pipe dreaming about information as complete as 
your September 1980 Radio Electronics article!  Anyway, the reason I want the 
schematic is to convert the transmitter unit into an IR receiver and RF 
transmitter unit.  This should be fairly easy because they use the NEC 6121G 
chip in the transmitter and that chip is fairly well documented in NEC data 
books.  The output (pin 5) goes to an rf trasmitter of about 300 MHZ.  I 
managed to get my CORE unit learn the code from pin 5.  Now All I have to do is
learn how to is figure out how to make the rf transmitter work indepndantly 
with an MC3373 receiver or build my own receiver.  I would appreciate any 
comments from anyone who has hacked with the transmitter.  Ever since I 
purchased a CORE I've been looking for a way of working the X-10's with IR. 
Seems like the only thing that did that was the GE/Radio Shack "Home Minder" 
and it is no longer available.  By the way Steve, I haven't seen you comment on
Steve Wozniak's CORE.  I am pretty sure you are using one.  If so, what's your

Believe it or not, I don't have a CORE remote control. I have a few others

though. I'm gadget happy enough that I probably need one. The upcoming INK 
article will contain all the particulars about transmittin g (I suppose that 
includes receiving) X-10 codes. If you can find these pulse trains any where 
int the box you have with a scope you should be able to intercept them or 
introduce them. I know the old ultrasonic remote control unit could be 
converted to IR (I did it). Too bad they don't make it anymore. Keep tuned.

Quite the contrary! My house would grind to a halt and be pitch black without 
the HCS. No, the HCS is still used but the printer is not. Because of the 
lightning problems where I am, the printer cable sometimes would pick up noise 
and glitch the system. The HCS would still be controlling everything perfectly 
but I'd find a ream of useless printout on the floor next to it. This only 
happened a few times but I said forget this and instead parallel monitor the 
system with a BCC52 and a time-lapse video recorder. When I get home I can view
the control operations on a crt rather that on paper. Think of it as a giant 
printer buffer with no paper.

Steve,   I have two of your HCS boards and one of them is currently controlling
the lights in my home.  A cable which carries two seperatly shielded pairs 
connects an IBM XT clone to the terminal port of the HCS.  The cable run is 
about 20 ft.  For whatever reason I cannot get the EXEC program from Robin 
Computing to download to the HCS (or upload) at a speed greater than 1200 baud.
To see if the cable length was a problem I took the second HCS board that I 
have and connected it up to the PC via a 3 ft. commercially made cable.  The 
same problem seems to exist.  I then connected the video out port to a monitor 
so that I would be able to see what is occurring.  It appears that the EXEC 
program is missing the prompt from the HCS at speeds over 1200 baud.  Is there 
any known fix??  I would appreciate any help. My event table is 77 events and 
it takes about 30 minutes at 1200 baud. (Whew!)        Thanks,      Evan P.S.

It may be that the other serial card has weaker drivers or less sensitive

This is my first communication with your bulletin board, and I am grateful to

summarize my interest in your work as follows: I am a long-time software user 
and developer who knows just enough about electronics and computer hardware to 
constantly want more knowledge.  I am really a frustrated engineer at heart who
hasn't the time to get a formal education in computer engineering, but wants to
know more.  That's what makes your BYTE columns so enjoyable to me.  Anyway, 
enough of background. I share your interest in home control devices.  I have 
had a houseful of BSR units for 4 years, along witan increasing number of IR 
remotes for appliances strung throughout the house.  Your remote control device
about a year ago sparked my interest in a similar project.  I have a PC version
of the BSR module that hooks up to a serial port.  With a little work, I can 
send software commands to the module to do real-time control of my BSR units 
from the PC.  I also have a voice-recognition board with a limited vocabulary 
(200 words) and a WATSON board that I hope to integrate into a complete home 
control system with my PC.  All I need is a real-time, RS232 device to send IR 
commands to a repeater.  Sorry, I can't continue this now, a real RIPPER of a

Sounds like a great marketing answer, but I think I know you better from your 
work.  Actually, I was going to get to the subscription part of my call last 
night, but we had a real blowout of a thunderstorm here and I had to pull the 
plug on all my stuff. (Sounds like more ideas for projects: I have never found 
low-end commercial surge supressors effective for lightning-induced surges. 
Besides, too many things here interconnect to get them all: phone lines, serial
cables, audio inputs, etc.).  

Just to expound on what I would like to connect as a system.  My voice board 
has enough of a vocabulary to respond to most things I could want a home 
control system to do if I link phrases together (turn the HALLWAY LIGHT on, 
TAPE show at TEN PM WEDNESDAY).  I can design the necessary software to 
organize the recognized key words into a command process I have preprogrammed 
to do.  If it needs a BSR module, I can direct a data stream to a serial port 
on my PC-BSR control module.  I am hoping to get my hands on some of the 
third-party software available for the WATSON board to push a voice file 
through when I need audio verification.  (Some recordings of John Gielgud as a 
butler would be nice...As you wish, sir). If this works out, I would look for 
some way to poll a series of microphone connected to the VR board so that I 
could identify the location of the caller, and thus know more to make decisions
from (which LIGHT? Ah! he's in the upstairs den.).  Also, one could then open 
only the circuit to a speaker in the caller's location, and not broadcast 
responses to others in the house.  If you have seen Mastervoice's 
BUTLER-IN-A-BOX at the last several COMDEX/Fall show, you will know where I 
have developed some of my ideas.  Anyway, the first ingredient I need is a way 
to record and retransmit IR patterns, similar to your IR remote replacer, that 
works interactively with a computers I/O port.  Enough said.  I will leave you 
with this thought, get to the subscription section, and await your next column.

I'm actually the one who did the article for the third issue of INK.  The

described in the article.  Originally, CCI was going to handle the product.  I 
believe Micromint is the only one selling it now.  Individual modules can be 
obtained directly from X-10 (they have an ad in the same issue).

While we're on the subject, we just got a 2-way X-10 module from X-10 (a 
sticker on the back says "Unit 1").  This thing not only transmits X-10 codes 
but will also receive them.  The front end on it filters what it hears on the 
power line, confirms that it's valid X-10 code, then sends clean 1-ms pulses to
the computer.  I have to do some software this weekend to see it work.  I'll be
doing a short follow-up article in the fourth issue of INK that describes the 
receiver portion.  X-10 also defined some new codes in their protocol that 
definitely look useful.

What possibilities the UNIT 1 conjures up! Is this going to be a real thing in 
the future (i.e. should I wait on the current X-10) or is this  just an 
evaluation unit with no real future ahead? Please give me some direction, if 
you please.

Oh it is definitely a real thing for the future.  I don't know their production
plans or timeframe, but I'm quite sure it will be produced in quantity.  With 
the low cost of these modules, though, why bother waiting if you want to start 
playing with the transmitter portion now?  You can get your transmitter code 
working, then get the receiver when it's ready.  X-10's latest ad says that a 
2-way module is coming, so even X-10 is starting to promote it.

The additions to the protocol start me wondering about some of X-10's future 
plans.  They've added such function codes as "hail request" and "hail 
acknowledge," used by a transmitter to find out if there are any other 
transmitters in listening range; "all lights off" (previously there was only 
"all lights on" and "all units off"); "status request," "status on," and 
"status off," used to query the RF transceiver module to find out whether it's 
on or off; and "extended data," used to send one or more bytes of 8-bit data. 
Things are starting to look interesting.

I've written some code to support the receiver functions already.  Surprisingly
enough, since the receiver front end does such a good filtering job, the 
receiver code is much simpler than the transmitter code.  Works like a charm. 
Now I just have to figure out how to make it work entirely in the background.

It seems to me they should also produce a device that will allow multiple

you have to buy a unit.

I've found that noisy switchs on other appliances will cause false activation 
of the old brown modules. I no experience with the new tan ones, but the only 
problems I've had with the old ones is burnout or relay welding (using loads 
well within the specs).

I'm beginning to think that my problem is specific to this one module attached 
to my TV.  It went on again today - unanticipated - without anyone turning on 
an electrical device.  Of course other appliances were operating at the time --
could be a refrigerator kicking in, for instance. Then again maybe my house is 
spooked and the tan modules wouldn't help much either  :-) !!   (This problem 
is actually kind of fun because its only that one module anyway.  It would be 
something else if I had an appliance that shouldn't be left on unattended) 
Under computer control, I really like Steve's method of sending refresh codes 
out to make sure everything is going the way it should.  That not only fixes 
the problem with the old modules, it is smart programming.   ...Taegan

.       Have you seen the latest issue of Radio-Electronics?  In it they have 
plans for a current carrier modem that is supposedly capable of 9600 baud.  It 
seems that something like this could be used for home control (especially if it
could be shrunk down into a smaller package);  the only thing that is lacking 
is a protocol for sending information to various devices that would be 
connected to the receiving end.  I wonder if anybody would be interested in 
putting forth a proposed spec for such a thing?

You can't run the TTL signal more than a few feet before you pick up noise.  It
sounds like you really only have two choices: use a 40-character display 
broadcast to all the monitors via a composite video signal, or use a terminal 
board at each display sight and transmit the data serially to each terminal. 
Trying to send an 80-column display in video form throughout the house sounds 
like a losing proposition.

We've experimented with power line modems and had limited success.  Steve had 
wanted to do an article using the NE5050, but experimentation showed that the 
error rate was so high you needed a pretty robust error detection/correction 
scheme for it to be of any use.  By the time you implement the error handling 
on each node, the node becomes real expensive.  The RE modems might be fun to 
play with, but I wouldn't try putting together a real product with them.

I have my doubts about the reliability of the RE circuit. It may transmit and 
receive 9600 bps but two characters sequentially? ........... or, with noise on
the line? ......... It is not a particularily sophisticated circuit. We have 
experimented with far better circuits and I still don't think powerline 
communication is reliable except if there is never any electrical noise 
(doubtful) or both sides incorporate processor/buffer/erro r checking 
(expensive). Remember, you get what you pay for. If a circuit that inexpensive 
really worked, you'd see it commercially available with lots of competition.

I think you misunderstood something somewhere.  Micromint sells an X-10 module,
cable, and software that connects the computer to the power line so it can send
X-10 commands.  While the module can be used with any computer with the proper 
interface, cables and software are available for the BCC52, BCC180, and IBM PC.
The software simply allows user programs to send X-10 commands; it is not home 
control software.  I had mentioned that I'm working on home control software 
using the module and a BCC180 in my spare time, but it won't run on an SB180 
and won't be a product anytime in the near future.

The module that Micromint sells is described in an article I wrote for the 
third issue of Circuit Cellar INK.

                Copr. 1989  by Taegan D. Goddard
        ------------------------------------------------



I. Introduction
   ------------

     Have you ever wondered what else your computer could do?
Word Processing, spreadsheets, and data bases are fine -- but
wouldn't it be nice if your investment in hardware would pay for
itself in other ways?  Personal computers are now being used for
home and office control. Scientists use them to monitor
experiments.  The Game Port Monitor allows you to hook up sensors
to your machine's game port so that you can begin to experiment
with environmental monitoring.

       o  Measure light intensity in a room.
       o  Monitor windows and doors in your home.
       o  Measure temperature.
       o  Observe human movement through open spaces.

Each of these things can be accomplished with your PC!  Add a
computer interface for the BSR X-10 wireless appliance and light
modules, and you have the beginnings of a mini home control
system!  With the PC game port and a few inexpensive electronic
components, you can add real-time environment sensing to your own
programs!  
     Let the Game Port Monitor lead you into this exciting (and
relatively un-tapped) world of computing...


II. But What does it cost?
    ----------------------

     The range of electronic components you can attach to the
PC's game port are many -- from simple photocells and thermistors
to more complex infrared motion detectors. Less than $5 spent at
an electronics store can buy all that you need to measure light
intensity and temperature. A very small price to pay to equip
your computer with 2 human senses!
     Likewise, the software is also very inexpensive. The Game
Port Monitor, a shareware program (it's not free!), costs just
$5. Please send a check for $5 to:

                       35 Woodside Circle
                       Hartford, CT 06105

to register your copy of the program. You will be sent future
updates of the program and additional tips for environmental
monitoring and home control. (I am also currently working on a
mini home control program using the BSR X-10 controller for
output and the PC game port for input.) 
     Please send any comments you may have about this program -
your input will help me create better updates! 


III. Function Key Assignments - Game Port Monitor
     ---------------------------------------------------

     <F1> Calls up the help screen, listing all of the following
          key assignments.

     <F2> Graphs all incoming data from the transducers attached
          to the analog inputs of the game port.

     <F3> Shows program status: Time monitoring started, current
          time, total number of observations, and average
          observations made each second.

     <F4> Begin saving incoming data to a file every 15 seconds.
          All data is saved in a file named GAMEPORT.DAT. This
          data can be imported into your spreadsheet or data base
          program for further analysis.

     <F5> Stop saving data to disk file.

     <F6> Turn off screen display in order to prevent monitor
          burn problems. Often you will want to leave your
          computer on for a long period of time to monitor
          certain inputs. This option can be used to prevent
          damage to your monitor (or to stop prying eyes!)

     <F7> Clear lower portion of screen. Shows only the actual
          data boxes for analog and digital inputs, turning off
          any other information screen at the bottom of the
          display.

     <F8> Refresh Screen Display. Left over from earlier versions
          of the program where certain interrupts caused problems
          with the screen display. The bugs have been fixed in
          this version of the program, but someone may still want
          to use it!

     <F9> Exit to the DOS prompt. Allows user to rename data
          file, or perform any other needed task outside the
          program, like using your word processor or spreadsheet.
          
    <F10> Exit Game Port Monitor. Ends monitoring session.






IV. Pin Locations on the PC game port
    ---------------------------------

     The following chart shows all pin assignments on the PC game
port:

     15                       +5 volts
----------------------------------------------------------------

NOTE:  It is always safest to turn off your computer when        
       making connections to the game port.


V. How do I hook up sensors to my PC's game port?
   ----------------------------------------------
     
     The joystick is a typical device you would attach to the
PC's game port. It has two variable resistors attached to the
analog inputs, each corresponding to the X or Y axis. The buttons
on the joystick are digital inputs. Each can only be ON or OFF.
If you have a joystick, use the Game Port Monitor to find out
what your joystick actually does...

ANALOG INPUTS:
     A photocell (light sensor) or thermistor (temperature
sensor) has two leads coming from it. Each essentially acts as a
variable resistor - the resistance of the device changes as the
temperature or light changes. Attach one lead to +5 volts and the
other to an analog input pin on the game port. That's all there
is to it...
     The Game Port Monitor will now show a reading from    0-255
corresponding to the resistance of the device. If you are using a
thermistor, you can calibrate these readings to an actual
temperature reading. Submerge the thermistor in a pan of boiling
water. The reading Game Port Monitor gives you corresponds to 100
degrees centigrade. Do the same with a pan of ice cold water, and
you have the reading for 0 degrees centigrade. Most thermistors
give linear readings over this temperature range, so you can
figure out all points on the line, and thus the temperature for
any reading the program gives you.

DIGITAL INPUTS:
     Any kind of switch, such as a relay contact on a motion
sensor, can be used with the digital inputs. Connect one lead to
the digital input pin on your PC's game port and the other to a
Ground (0 volts). 
     The Game Port Monitor gives you a reading telling the ON/OFF
status of the switch. With a magnetic type burglar alarm switch
you can sense whether a door or window is open or closed.

     Once you have found out how to give your computer sensing
capabilities, you can write programs exploiting this new found
ability of your computer. Register your copy of the Game Port
Monitor and you'll be part of a forum concerned with these types
of experiments and home control.  The Game Port Monitor will
simplify your learning process and instantly show you what your
sensors are doing.
     Look for PC-ROWER.ARC on your local BBS. This program lets
you computerize your rowing machine! Many more programs of this
type will follow.

     I make no warrantee or guarantees for the use of this
software or the hook-up of devices to your computer. Attaching
simple electronic components such as light and temperature
sensors is a relatively easy operation to complete, and poses
very little risk to your equipment, BUT if you are in doubt of
your skills then please get assistance or have someone else do
the connections for you.
     Thank you in advance for your support of the shareware
concept!

I am experimenting with home control using an IBM PC motherboard and the X-10 
Powerhouse to control lights and appliances.  I am writing my control program 
in QuickBASIC 4.0.  My question to anyone:  What is the best type of video card
to use if I want to send the video signal throughout the house to various 
monitors and TVs?   Another question:  Where is the best place to order 
thermistors (150k) that measure temperatures in the normal household temp 
range? Thanks much for any help you can give.    ...Taegan

Taegan, I would use an old CGA color card with composite output (from the RCA 
jack) cause it is easiest to boost arround many cables (Radio Shack quad 
amplifier box) and to convert with a little board (back of byte) from the video
games to RF for TV reception where you want to use a tv and some monitors too. 
I think you can put some channel 4 rf on top of the composite video signal and 
get both  on the cable. The amplifiers may not handle the low frequency video 
unless you add a larger capacitor on the internal coupling to go below channel 
2, I haven't tried it.  there are also dc optical volume controls for remote 
use in the surplus market that you can run with a bsr dimmer to a small 115v 
lamp thru fiber optic cable to the photocell to adjust volume, though you may 
need to rectify and filter the bulb power to reduce ripple at 120 hz.

Thanks for the info David...  Thinking it over, I would be limited to 40 
columns of text resolution on a TV monitor with a CGA card (unless I'm 
mistaken). Color for the displays doesn't matter to me, but 80 columns would be
nice.  Am I wrong on this? I'd really like to switch video inputs to the TV 
when I want to check the status of the control system. Unless I get a high 
resolution TV/monitor I wont be able to see 80 columns.  Does this thinking 
aloud make any sense to you..?

Attention X-10 Powerhouse users!

I am currently considering developing a memory-resident (or Terminate
and Stay-Resident) control program for the X-10 Powerhouse.  This
program would be able to "pop-up" over Lotus 123, Word Perfect, and many
other programs allowing you to trigger any of the 256 codes your X-10
interface is capable of transmitting.

Is there a market out there for this type of program?  I would anticipate
that TSRX10 would cost a little more than SENDX10 or SYNCHX10, perhaps
fifteen dollars ($15).

By registering your copies of SENDX10 and SYNCHX10, you are also voting
for continued development of these types of programs.  If you become a
registered user of SENDX10 or SYNCHX10, I will thank you by offering
my additional home control programs to you at a substantial discount.

Thanks for your support!

Taegan, I even once converted a console and interfaced it with my ZX-81 
Sinclair ( remember them) using opto-isolators.It worked ok but wasnt 
very reliable and I had to devote the Sinclair to it. At that time or a 
little later the coco x-10 was 100 bucks. I think I might have a 
schematic for the coco x-10 , I'll have to look . If you need it let me 
know.

Taegan, just looked and have no scematic , but I have the pinout of the 
coco cassette port which is where the x-10 plugs in. It is not a serial 
port. Are you talking about a differtent type of x-10 maybe for tandy 
1000"s & up. Anyway here are the pinouts.
 
 
 1- Remote for cassette motor
 2- Signal Ground
 3- Remote for cassette motor
 4- Audio input
 5- Audio output
 
                                        
Taegan, I hope this help's but this port can not be connected to a 
serial port, these are line level audio signals. You could probably 
make an interface ahead of audio stages but it probably isn't worth it. 
If youre friend had an X-10 for a Tandy 1000 series then it's probably a 
serial type.

1. INTRODUCTION

If you like to write your own software, this manual is for you.

It is assumed that you are familiar with Basic programming and some knowledge of
Binary programming will also be useful.  This manual should be sufficient to let
you write simple Basic programs to set and read the Real Time Clock in the
Interface and to turn modules on and off manually etc. For more complex programs
involving "Timed Events" etc. you should refer to the Programming Guide which
deals in more detail with Binary and Hex programming.

The Utility Program is written in Basic and stored in ASCII format to allow
merging with an existing Basic Program. This lets you write programs in Basic
and use sub-routines to perform functions such as setting the clock, uploading
or downloading timer events etc.



2. USING THE UTILITY PROGRAM

The Utility Program sub-routines occupy Basic lines 19999 - 372 and therefore
any program using the sub-routines should leave these lines free. Alternatively
you could re-number the sub-routines remembering to update the GOSUB addresses
also.

There are two ways to load the Utilities.

1. If you are writing a completely new program, you can  just LOAD "X1"

2. If you are combining the Utilities with an existing program, (e.g. MY
PROGRAM) you first load your existing program  i.e. LOAD "MY PROGRAM", then
merge the Utilities into the memory area by MERGE "X1". Once merged your
program is ready to run.

NOTE. If you forget to merge the Utilities, your prm will not run.



3. VARIABLES

Below is a list of variables used by the Utility program. These variables should
only be used in your program to transfer data between the main program and the
sub-routine and vice versa.

A              FUNCTION
A$             GRAPH (2, 256)
ADDR1          HITEMP
ADDR2          HIUNIT
ADDRESS        HOURS
BTEMP          HOUSECODE
BASECODE       LEVEL
CHKSUM         LOUNIT
CODCONV (16)   MINS
COUNT          PORT
DAY            STATUS
EVENT          TIM (8, 128)
FTEMP          XTEMP



4. SUB-ROUTINE LOCATIONS

The Utility Program has 9 sub-routines which give the Basic Programmer full
control over the Interface. These are located at the following lines.

2   Initializing the com. port / defining the variables.
21   Setting the real time clock in the interface.
22   Setting the base housecode in the Interface.
23   Reading the real time clock from the Interface.
25   Sending an INSTANT on or off X-10 code.
28   Downloading a Timer Event to the Interface.
29   Uploading ALL Timer Events from the Interface.
21   Downloading Graphics Data to the Interface.
211   Uploading ALL Graphics Data from the Interface

STATUS
The Utility sub-routines return a status value indicating the following:

If 'STATUS = 1' then 'GOSUB' was successful.
If 'STATUS = ' then 'GOSUB' was successful but the Interface indicated that it
had been powered down and contains no data.
If 'STATUS = -1' then 'GOSUB' was unsuccessful. This indicates that there may be
a problem with the connections to the Interface or the Interface may not have
power.



5. SETTING THE COM PORT

LINE 2

This sub-routine initializes the communications port (COM1).

This sub-routine also assigns all the variables used within the utility
sub-routines. It should be called at the beginning of a program and should only
be called once. If called more than once an error will occur.

EXAMPLE

1      GOSUB 2
        Rest of the Basic Program.

19999
  '
  '     Utilities
  '
372



6. SETTING THE REAL TIME CLOCK

To set the real time clock in the Interface.

LINE 21

Variables passed to the sub-routine.
DAY     (1-7)
HOURS   (-23)
MINS    (-59)

Variables passed from the sub-routine.
STATUS  (-1, , 1)

Before calling this sub-routine, first assign a value to DAY, HOURS and MINS.
Then call the sub-routine. The values stored in DAY, HOURS and MINS will then be
transferred to the Interface. On returning from the sub-routine the STATUS
should be compared with the value -1 to ensure that the download was successful.

EXAMPLE
5       CLS:PRINT "Setting the real time clock"  : PRINT
1      GOSUB 2
2      INPUT "Enter the DAY (1= Sun, 7=Sat) "; DAY
3      INPUT "Enter the HOURS (-23) "; HOURS
4      INPUT "Enter the MINUTES (-59) "; MINS
5      GOSUB 21:IF STATUS =-1 THEN PRINT
        "*** ERROR***": END
6      PRINT:PRINT "The time has been set": END



7. READING THE REAL TIME CLOCK

LINE 23

Variables passed to the sub-routine
NONE

Variables passed from the sub-routine

DAY     (1-7)
HOURS   (-23)
MINS    (-59)
STATUS  (-1, , 1)

To read the time from the Interface, call the sub-routine. The time will then be
transferred to the variables DAY, HOURS and MINS, providing the STATUS is not
returned -1.

EXAMPLE

1      GOSUB 2
2      GOSUB 23: IF STATUS =-1 THEN PRINT
        "***ERROR***" :END
3      PRINT "DAY = "; DAY; "HOURS = "; HOURS;
        "MINUTES = "; MINS
4      END



8. SETTING THE BASE HOUSECODE

LINE 22

Variables passed to the sub-routine.
BASECODE  (1-16)

Variables passed from the sub-routine.
STATUS  (-1, , 1)

To set the Base Housecode in the Interface, first assign a value to BASECODE as
shown below.
        A=1     B=2     C=3     D=4
        E=5     J=1    K=11    L=12
        M=13    N=14    O=15    P=16
Then call the sub-routine to change the Base housecode in the Interface.

NOTE. calling this sub-routine will erase all the data stored in the Interface.

EXAMPLE
5       CLS:PRINT "Setting the base Housecode": PRINT
1      GOSUB 2
2      INPUT "Enter Base Housecode"; A$:BASECODE=ASC
        (A$) - 64
3      GOSUB 22: IF STATUS =-1 THEN PRINT
        "***ERROR***" :END
4      PRINT:PRINT "The Base Housecode has been set" :END



9. SENDING AN INSTANT X-10 CODE

LINE 25

Variables passed to the sub-routine.

FUNCTION

This is a number between 1 and 3. 1=ON  2=OFF  3=DIM.

LEVEL

This is a number between  and 15 which sets the intensity of the DIM command.
If FUNCTION is set to 1 or 2, LEVEL will be ignored.

HOUSECODE

This is a value between 1 and 16 where A=1 and P=16.

LOUNIT

This is a bit mapped value corresponding to the unit codes 1 thru 8 as follows:

   1=128   2=64    3=32    4=16
   5=8     6=4     7=2      8=1


HIUNIT

This is a bit mapped value corresponding to the unit codes 9 thru 16 as follows:

   9=128   1=64   11=32   12=16
   13=8    14=4     5=2    16=1


Variables passed from the sub-routine.

STATUS       (-1, , 1)

FUNCTION     (1, 2, 3)

LOUNIT       ( - 255)

HIUNIT       ( - 255)

HOUSECODE    ( - 16)

 BASECODE    ( - 16)


To transmit an X-10 code instantly, you must first assign values to FUNCTION,
LEVEL, HOUSECODE, LOUNIT and HIUNIT relating to the code to be sent; then call
the sub-routine. If the STATUS is not -1, the sub-routine will return the values
of FUNCTION, LEVEL, HOUSECODE, LOUNIT and HIUNIT as sent to the Interface. These
values can then be used by your program to verify the code sent.

EXAMPLE
1      GOSUB 2
2      LEVEL =
3      INPUT " Enter the FUNCTION (1=On 2=Off 3=Dim)"
        ; FUNCTION
4      IF FUNCTION=3 THEN PRINT :INPUT " Enter the
        LEVEL " ; LEVEL
5      PRINT:INPUT " Enter the HOUSECODE (A-P) " ; A$:
        HOUSECODE=ASC(A$) - 64
6      PRINT:INPUT " Enter the value for HIUNIT
        (=NONE) " ; HIUNIT
7      PRINT:INPUT " Enter the value for LOUNIT
        (=NONE) " ; LOUNIT
8      GOSUB 25: IF STATUS =-1 THEN PRINT
        " *** ERROR***" : END
9       PRINT " The X-10 message has been sent" : END



10. DOWNLOADING GRAPHICS DATA

LINE 21

Variables passed to the sub-routine
ADDRESS ( - 255)

Data stored in Basic array
GRAPH (, ADDRESS)  ( - 254)
GRAPH (1, ADDRESS)  ( - 254)

Variables passed from the sub-routine
STATUS  (-1, , 1)

This sub-routine takes the data stored in the Basic arrays GRAPH (, ADDRESS)
and GRAPH (1, ADDRESS) and transfers it to the RAM in the INTERFACE. NOTE - The
values stored in these arrays should never equal 255. An error will occur if
this happens.

EXAMPLE
1      CLS: PRINT " Downloading Graphics data " : PRINT
2      GOSUB 2
3      INPUT " Enter the ADDRESS (-255) " ; ADDRESS
4      PRINT : INPUT "DATA 1"; GRAPH (,ADDRESS)
5      PRINT : INPUT "DATA 2"; GRAPH (1, ADDRESS)
6      GOSUB 21 : IF STATUS =-1 THEN PRINT
        " ***ERROR*** " : END
7      PRINT " DONE " : END



11. UPLOADING GRAPHICS DATA

LINE 211

Variables passed to the sub-routine
NONE

Variables passed from the sub-routine
STATUS  (-1, , 1)

Data stored in Basic array      GRAPH  (, X)
                                GRAPH  (1, X)

This sub-routine is used to request the Interface to upload ALL 256 pairs of
GRAPHICS data and store them in a Basic array GRAPH (, X) and GRAPH (1, X)
overwriting any data previously stored in the array.

EXAMPLE

1      CLS : PRINT " Uploading Graphics Data " : PRINT
2      GOSUB 2
3      GOSUB 211 : IF STATUS =-1 THEN PRINT
        " ***ERROR*** " : END
4      PRINT " DONE " : END



12. DOWNLOADING TIMER EVENTS

LINE 28

Variables passed to the sub-routine.
ADDRESS  ( - 127)

Basic array.
        TIM     (,  ADDRESS)   (Equals BYTE 2)
        TIM     (1,  ADDRESS)   (Equals BYTE 2 1)
        TIM     (2,  ADDRESS)   (Equals BYTE 2 2)
        TIM     (3,  ADDRESS)   (Equals BYTE 2 3)
        TIM     (4,  ADDRESS)   (Equals BYTE 2 4)
        TIM     (5,  ADDRESS)   (Equals BYTE 2 5)
        TIM     (6,  ADDRESS)   (Equals BYTE 2 6)
        TIM     (7,  ADDRESS)   (Equals BYTE 2 7)

Variables passed from the sub-routine.

STATUS   (-1, , 1)

This sub-routine should only be used by programmers familiar with Binary
Programming and the Timer Events downloading information on page 21 of the
Programming Guide, supplied with the Interface.

First set up the arrays with the data relating to the timed events required, and
then call the sub-routine. The timer events will be transferred to the Interface
and a STATUS = 1 will be returned if the download was successful.

EXAMPLE

1      CLS : PRINT " Downloading a Timer Event " : PRINT
2      GOSUB 2
3      INPUT " Enter the ADDRESS ( - 127) " ; ADDRESS
4      FOR X = 1 to 7
5      PRINT " Enter the Data for BYTE"; 2+X; : INPUT
        TIM (X, ADDRESS) : NEXT X
6      GOSUB 28 : IF STATUS =-1 THEN PRINT
        " *** ERROR *** " : END
7      PRINT " DONE " : END



13. UPLOADING TIMER EVENTS

LINE 29

Variables passed to the sub-routine.
NONE

Variables passed from the sub-routine.

STATUS  (-1, , 1)

Data stored in Basic array

TIM   (, X) .....TIM  (7, X)

This sub-routine requests the Interface to upload ALL 128 Timer Events and store
them in the Basic arrays TIM (, X) thru TIM (7, X).

EXAMPLE

1      CLS : PRINT " Uploading Timer Event " : PRINT
2      GOSUB 2
3      GOSUB 29 : IF STATUS =-1 THEN PRINT
        " *** ERROR *** " : END
4      PRINT " DONE " : END
