Anyone here know the serial port pinout of the 1/8 inch "stereo"
plug and socket on the KAT500 rear panel?
I use the serial cable that came with my XG3 ...
XG3 User Manual/Schematic shows serial in (PC TxD - pin 3) on tip and
Serial Out (PC RxD - pin 2) on ring. Common/ground (PC pin 5 and shell)
is sleeve.

device server. The device server has a DB9 socket, so I need to make a DB9 to 1/8 inch
plug cable to control the tuner remotely.
I looked in the manual, however, I cant find a pin out of the plug there.
Would be nice to have the signal designations as well for the TRS plug so as to
make up the cable correctly.
