HIR GUYS? LOOK IAM NEW TO THE SITES AND WOULD LIKE HELP ON X10....I RECEIVED A PROJECT ON X10 AND WOULD LIKE TO BUILD ONE WITH TRANSMITTER AND RECEIVER, I WOULD LIKE UR HELP ON SCHEMATICS
-
First: Welcome! There's a lot combinded knowledge among the folks here. Most likely your problem has already been solved at least once. If not, there are a lot of us that are willing to steer you in the right right direction so you can "invent your own wheel".
Second: A "point of etiquette" All CAPS are not needed. It actually makes your message harder to read. It equates to screeming.
Third: Please post more details of what you're trying to do.
Fourth: While you're waiting for replies, search this forum. It will give you some hints as well as help you avoid some of the pitfalls and crap some of us have already stepped in.

NTK,
Yes a little more detail would help forum users provide more specific answers. However the following site provides many schematics, modifications, and technical information for X10 modules.

Just take some of the schematics as only good for some versions of a module. The Appliance Module one was not close to mine.
X10 has some of their RF Transmittine schematics on file with the FCC and last time I looked they where not flagged as private don't allow access. Many vendors flag theirs as proprietary and private.

Thanks guys, well i will look at ur links in the moment, but my project must be a demonstration platform which consist of Transmitter and receiver communicating with automation protocol, low cost and a stand alone.....twisted pair as communication medium.
-
The twisted pair as a com path requirement, pretty much puts X10 out of your project. X10 is strictly PLC and RF.
-
As Dave said. X10 is powerline signals and synchronized to the zero crossing of the AC Voltage.
There is in the X10 Support Area Users manuals section; near the bottom of the list. The X10 protocol and the TW523 Interface that takes signals and send them over the powerlines.

For those looking for a schematic of the SR227, I have reverse engineered one.
Updated 11/12/11 Replaced resistor symbols. No other changes.
Please post any needed additions or correction and I will update the drawing.
Some of the component values are not shown. As soon as I have a spare to open up again, I will try to update the values.

Thank you for the schematic and work devoted to do it.
Helpful from me.
Do you know how old it was?
In the last few years X10 had redesigned modules. Using more readily available parts. Including a different manufacturers microcontroller, surface mounted parts and power supplies running in the 4.5 to 5.2 volt DC range.
I know the newer appliance modules and lamp modules have the new parts and PCBs.
-
The schematic is from an SR227 that I purchased in 2009. I did a mod to make it automatically turn off after a short (32 sec.) delay to use it with my Add-A-Motor drapery control. Prior to the mod, I would need to use a macro or remember to turn the module off after each open or close cycle of the drapes. The mod involves adding a CD4040 CMOS IC inside the module sandwiched between the two boards. I also made an extensive mod to the Add-A-Motor. I redesigned the circuit and ordered PC boards from ExpressPCB. The board layout has 2 circuits and I had to buy 3 boards. I still have 2 boards (4 circuits). The Add-A-Motor kept slipping and getting out of sync. More details are available. Here is a photo of the AGC board in the SR227. The 2 ICs in the center are for the SR227 CD4040 mod.
-
If I could attach a zip file, I would post the ExpressPCB file. I assume that changing the extension on a file to an allowed type is not permitted, otherwise, I could attach the file and then you could download the file and rename it to the ExpressPCB file. ExpressPCB is free software that you can download to create schematics and board layouts. I use CuteWriter (free software) to convert anything that can be printed to a pdf file.

Does anyone know if one can modify the SR227 to disable the local override? I have LED light, and the leakage current is enough to illuminate it when otherwise "off".

Just a bump wondering if anyone has, yet, found a way to do this (disable the trickle current used for local override).
-
Looked at Backward Engineering's schematic. Linked above. It looks like the am I on or off sensor and Local Control sensor are the same circuit. Not sure if a part can be removed to lower the current.
The current can't be completely removed. As it uses the sensor circuit to determine if it is On or Off. If removed the module can't determine if it is On or Off and will fire the ratchet mechanism a few times trying. Like a machine gun sound. When you try and turn it On.

There have been instructions on how to do it posted in the past. unfortunately, :( the Bartana website is now up for sale

I also found this on the cocoontech site which seems to be on point:

The jumper mentioned would probably defeat the Local Control Sensor from turning the module on when the loads local switch was toggled from on to off and back on.
It will not defeat the actual sensing current from keeping sensitive loads like LEDs from glowing or pulsing.
The module also has a sensing circuit to determine if it is on or off. That circuit can not be defeated or it will pulse like a machine gun when you try to change its on or off status.
Now the latest ones could be different. X10WTI changed the appliance module to be more friendly to sensitive loads the socket may also have been updated.
The fix. Local Control frequently could be defeated. By putting an electrical cube tap on the outlet and putting a 7W incandescent night light and the normal load on the module. It normally would load down the sensing voltage so a sensitive load would not flash or pulse when off.
Found this in a web search. http://www.komar.org/how-to/fix-repair-broken-sr227-x10-super-socket/
Covers the broken ratchet switch actuator breaking and switch contacts with dirty contacts. Causing the machine gun sound when changing on and off.
