K3/P3 should not use a Y adapter - the design is for series connection.
Computer connects to the RS-232 input of P3, P3 RS-232 output connects
to the RS-232 input of K3 using the cable supplied with the P3.  Set
both units and the computer (logging software) for 38,400 bps for best
results.

There is a significant amount of K3 <-> P3 traffic on the RS-232 link
that the computer has no need to see and will cause collisions/issues
with logging software that does not understand the undocumented data.
