Hello guys,

does someone of you have any information about the the MUX32 multidrop 
protocol for EMS MM80MicroMux Bus Module?

At the moment I'm using EMS LRP820 RFID readers and I want to find out 
how the module is communicating with the readers and also how the 
response looks like. I would like to use other readers and I have to 
programm it in this way. Also the timing would be very important.

I'm looking forward to all information you have.

Thank you.
Salute Miros
