Adding a P3 to a "Busy" K3 RS232 connector?

I'm hoping to add a P3 to one of the two K3s that I currently run in SO2R
configuration. Both K3s are connected to a microHam MK2R+. The RS232 and
ACC connectors on both radios are "busy" with both being connected to the
MK2R+ . and one with an additional Y-cable that provides band data to a
SteppIR controller . and both ACCs providing band data through the MK2R+
and on to band decoders that switch bandpass filters in and out. At least
I think so.. because I always have to get out my notes and diagrams to sort
things out every time I disconnect/connect or make any changes or
adjustments.

My question: Will I create any conflicts when I add a P3 to one of the
radios? I'm hoping I can just run a cable from the RS232 connector on the
K3 to the "xcvr" RS232 P3 connector, and move the cable currently connected
to the K3 RS232 to the "PC" RS232 connector on the P3 ... and all will be
well and good!?

Has anyone with a similar setup been there and done that? I'd rather avoid
any unwanted surprises if I can. Comments?

Don, N5LZ

That's the correct connection. Set K3, P3, MK2R+ and your logging
software all to 38,400 bps to avoid issues with shifting data rates.

You may find it more convenient to use the serial port capability of
MK2R+ with a TTL to RS-232 converter (see the MK2R+ manual pages 60 -
62) for SteppIR control.

Thank you very much Joe. The MK2R+ has been running perfectly with the two
K3s ... and I just don't want to upset the cart.

This should work fine. The P3 is designed to coexist between the K3 and
external s/w on the RS-232 connection in this situation.
