Alan,
I recently had the same problem. The following worked for me:
ACC Pin 2 - Auxbus: connect to green wire - Pin 6 on DB-9
ACC Pin 7 - K3 on signal: connect to red wire - Pin 8 on DB-9
ACC Pin 10 - Keyout: connect to black wire - Pin 9 on DB-9
ACC Pin 5 or 12 - Gnd: connect to bare wire - Pin 1 on DB-9
Also, you should put a pull up resistor between pin 10 and pin 7 on the ACC
connector as pin 10 is an open collector output on Q7
(MMBT3904), according to the KIO3 schematic. Finally, make sure TX INH is
is set to OFF.

Subject: [Elecraft] Intefrace K3 and transverter
I am looking for a description for a cable. I have a K3 with the KXV3 and
2 Elecraft transverters (XV432 and XV144). I have the needed hardware
connectors. I am really struggling with the connections. Does anyone
have a list of what pins on the K3 go to what pins on the XVxxx?
