It is with some chagrin that I must retract my original assertion that the Radio Shack #26-3142 remote controller was just a BSR unit with the name changed. After some experimenting with my units I can confidently say that the RS unit DOES NOT FUNCTION if you try to talk to it using RS232 voltage levels. After making this determination, I opened up both units to look inside. Both use the 80C48 microcontroller. Both use 6116-2 RAM. In fact, most of the components are the same. This is to be expected. So, I guess the only hardware design difference is in the computer interface. The BSR unit has a 5 pin DIN receptacle that the cable to the computer plugs into via a D-25-to-5-pin-DIN-plug adapter cable, and it is in the same place as the DIN plug on the RS unit. Perhaps, and I offer this only as sheer speculation, the pin functions on the DIN receptacle on the RS unit vis a vis I/O are the same as the functions on the DIN receptacle on the BSR unit, and the only difference is the voltage levels they operate at. If this is the case, here are the pinouts on my BSR unit (which operates on RS-232 voltage levels). Perhaps the control codes are the same, so my offer to mail a copy of my BSR X10 Programmers Reference still stands, if anyone is interested and will send me a USmail address. Once again, my apologies for the wrong info. Lee Thomison BITNET: OPTON@UHVAX1 landline: (713) 749-3127 all concievable disclaimers apply.
