Trouble with Digirig to KX3 Cat Control

When using the serial connection on from the Digirig to the KX3 using the Digirig 3-in-1 cable on COM8, get the message below, when I use the Elecraft cable on COM9it works fine, not sure what I am missing?

Digirig v1.9 with RS232

Let’s check the continuity on the cable:

…also the serial loopback test as shown here:

Please post your finding.

Guess I should have checked continuity first.

Ground S to S is fine,
Nothing on either the Tip to Tip or R1 to R.

I should have tested the cable as soon as I received it. Looking for my old set of coiled cables and for the life of me could not find them.
