Digital on Kenwood TS-440s

Looking for some help.

I have a kenwood TS440s with the 2 chips for digital/CAT fitted (I have 2 sets of chips, tried both) and a CAT cable.

No matter what I try I can not get CAT control to work.

I have fitted the chips, connected the cable, checked port evrerytime, reset radio many times (A=B and power buttons) and still no go.

Has anyone got any ideas?

TIA G5RAC

Hi @G5RAC,

I would first check that your CAT cable is the correct type for the TS-440S. The TS-440S does not use a basic serial cable; it needs the proper Kenwood/IF-232C style interface.

Also make sure you are using the ACC1 6-pin DIN port, not ACC2.

Try these settings:

4800 baud, 8 data bits, 2 stop bits, no parity, no handshake.

If that still does not work, I would suspect the cable/interface before the radio or chips.
