Post by thread:[EE]: X-10 OEM module

Hello all, I am investigating using a PLC (power line carrier) to send data around a building. I looked at X-10, but it seems to be limited to on and off. I looked at the devices (TW523) at x10.com. There is something about an extended data code, but it specificaly says that the OEM receiver can not receive those. Does anyone know of an off the shelf OEM module that I can use to send data over the power wires withing a building? I can modify my data format and speed on a whim, so anything is fine. The total length of the data is about 3 bytes, but again thats flexable. Thanks for any input, Shawn -- http://www.piclist.com#nomail Going offline?

Shawn, I believe that you are over looking the obvious in the TW523. This module is generic and all it does is place a pulse on the AC line to be received by ???. The TW523 is a transceiver, therefore if one TW523 were to place a series of data pulse on the AC line, then another TW523 will be able to receive these pulses. The important thing to remember it that X-10 modules wont be able to decode the data if not in an X-10 format, but I believe that all you want to do is send data packet to another location. The TW523 has a data in, data out and a zero crossing signal line. Use the zero crossing line to synchronize the data and send the data in a similar data method as X-10 (same pulse width and timing) but send as many bits in any order as needed to get the data to the other TW523. Decode it using your microcontroller and don't worry if X-10 modules can decode it or not. I believe that this will work for you with no problems. Gordon Varney {Original Message removed}

I looked at this a while ago and it seemed feasible. My potential customer disappeared so it never got finished, but I did get as far as picking up a NZ$40 set from an electronics retailer and doing some exploratory surgery on it -- http://www.piclist.com#nomail Going offline?

They indicate it should go to 350 Kbps - ever get this much? Also, have you any feel for noise problems and reliability of this type of communications? They also mention a unit that can do 10 Mbps. Do you know any more about that? - danM -- http://www.piclist.com hint: To leave the PICList EraseMEpiclist-unsubscribe-requestspam_OUTTakeThisOuTmitvma.mit.edu

Who makes that TW523? Thanks for the input, that sound like just what i want.

Take a look at http://www.hth.com for a power line device. {Quote hidden}> -----Original Message----- > From: Shawn Yates [RemoveMEsyatesTakeThisOuTCARETECHNOLOGIES.COM] > Sent: Saturday, October 07, 2000 6:48 PM > To: PICLISTEraseME.....MITVMA.MIT.EDU > Subject: [EE]: X-10 OEM module > > > Hello all, > > I am investigating using a PLC (power line carrier) to > send data around a building.

If I have to build a board myself, I am thinking about using this chip http://www.metricom-corp.com/spec1.html Thanks again Shawn -----Original Message----- From: Severson, Rob [RemoveMEseversonEraseMEEraseMEJGED.COM] Sent: Monday, October 09, 2000 10:09 AM To: RemoveMEPICLISTspam_OUTKILLspamMITVMA.MIT.EDU Subject: Re: [EE]: X-10 OEM module Take a look at http://www.hth.com for a power line device. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: "[PIC]:" PIC only "[EE]:" engineering "[OT]:" off topic "[AD]:" ad's

The folks who developed the free SNAP protocol also sell a power line modem, which should be exactly what you're after. They are, however, situated in Europe, and it may be that they don't sell 60Hz 120VAC stuff, but it's worth a check. http://www.hth.com/plm-24/ Much better than X-10 anything. -Adam Shawn Yates wrote: {Quote hidden}> > Hello all, > > I am investigating using a PLC (power line carrier) to send data around a building.
