Hi all,

Does Serial Data, RS422 mean anything to you guys ?

I know that the model 50 & 20 can be controlled via the Serial Data 3.5mm stereo jack input on the rear of the unit. (Baud 1200,8,n,1).

This is NOT an RS232 input and connecting a PC serial port to it will probably pop the receiving chip. (232 = +/-12v), This port expects TTL level data (+/-5v) so either a MAX232 type chip to act as a gateway between 232-TTL or RS422 (available on AMX & Crestron) uses acceptable voltage.

My dilemma is that I'm face with an Old Lifestyle Model 5, which DOES have the 3.5mm input but it's labeled "System Control" rather than "Serial Data". Does anyone have any experience with this blighter ?
