This cable is for audio and PTT (no CAT).
There is an accessory port in the back, but based on the age of the radio it’s unlikely that it supports serial CAT control.
If that’s the case then you should be able to get CAT control working. Next question is what electric levels does the port use. With older Kenwoods it’s usually RS-232, but logic levels is also a possibility.
For TS-50 CAT control I used a DTech USB to TTL Serial 5V Adapter Cable with FTDI FT232RL Chip 6 Pin 0.1 inch Pitch Female Socket Header UART IC Windows 11 10 8 7 Linux MAC OS (6ft, Black) from Amazon and a CN6 header cable. Pinned it out CN6 Cable USB to TTL Interface Cable
I connect GND, TXD, RXD, RTS,CTS, and use Hardware flow control.
COM4 Port setup: 4800 - RATE, 8 - Data, N - Parity, 2 - Stop, Hardware - Handshake/Flow Control
Works great!! Audio in/out is through the front mic connector.
