This screenshot is from page 13-16 of the full manual. Other: I have the Digirig ICOM RJ-45 cable plugged into the Mic port and the SP1 port. Also before I wired this up I checked the voltages on SP2 ring to ground and found about 3.4 volts peak to peak on the port during transition of data from the radio. I left the other CI-V comm settings at default. (Don’t forget to enable the CI-V port in the radio). I was able to use hamlib command line to read the freq. Then the sleeves are connected for the ground. So I wired the ID-5100 SP2 port ring to both the Tip & Ring1 on the DigiRig. The ring is both TX and RX (half duplex) and the sleeve is ground. For the CI-V control use SP2 on the ID-5100. I used hamlib to control the rig in a very basic sense (frequency) with the DigiRig. To control the rig with Fldigi I selected hamlib as it is the only one with ID-5100 support listed. I added a capture of the circuit for the data port that I found but I have not verified it as correct.

I have not used that Data port as it’s easier to use a memory card for what I need. I’m in the process of creating a new TRS - TRRS cable to see if that fixes my connection issue, but I’m wondering if anyone has any thoughts on how the cable could have gone faulty (or even if the cable is at fault).The image you show is used for “cloning”, setting parameters, DV Fast Data, and Firmware updates.

I tested the continuity for the TRS - TRRS cable and found that: Having the digirig connected to a different TRS - TRS cable, shows characters in the terminal as expected.Having the digirig connected to the faulty cable, no characters shown in the loopback test (or random characters).Having the digirig connected without any serial cable attached, shows characters in the terminal as expected.

While debugging I narrowed it down to a faulty cable, but I’m not 100% sure my assessment is accurate (also, why would it all of a sudden break).

This was fine until one time the connection using serial no longer worked. Everything was working fine until one day I switched to work on 20m (not sure if this is relevant) and for some reason I would get disconnects while transmitting (hitting retry on WSJT-X seemed to solve the issue). I’m having issues controlling my Icom IC-7000 using the serial port and CI-V cable.
