Patrick, Prologix GPIB-USB controller does not work as a GPIB bus sniffer. In DEVICE mode the controller reads the bus only if it has previously been addressed as a listener.

I am now reading with my Prologix device. I am just not sure that I am reading everything. I am trying to monitor the communication between a closed source App and some GPIB devices. After I set up imported and set up serial with PySerial I tried this: ser.write("++mode0\r\n") x=1 def read3(): while(x==1): print ser.read(1000) I also tried print ser.readline() I read the "ID" command sent out by the software but I could not read the response. Am I reading all the addresses with this set up or just one? Does anyone have some thoughts on why I don't read the response? Thanks yet again in advance-patrick _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
