Also, when a P3 is communicating with the K3, the RS-232 Y connection cable to
the Steppir and computer should be used at the P3 computer connector, not at the
K3. That will hide the internal P3-K3 data comms form the steppir controller.

David, that probably is it. My Y-device shows ohm meter continuity on all 9
pins. For the required isolation, at least one pin should show open.

I suspect that the problem is that you have two transmitters on the RS232
circuit. Maybe you can find some help in this similar situation.

I have a K3 / P3 / SteppIR SDA100. Everything is set to 38400 baud. I have
connected a Y-cable to the RS232 connection on the K3. One side of the Y is
connected to the SteppIR controller with a null modem inserted (as directed
by SteppIR instructions). The other side is connected to the XCVR
connection on the P3. Both work, but not at the same time. Unplugging one
of the Y connections makes the other work, and visa versa. Any ideas?
Perhaps there is a special & splitter that will provide the necessary
isolation?? Or perhaps I need to orient the Y a different way??
