Hello,
I would like to start to say thank you to any help anyone might be able to provide here.
I have tried every possible combination of settings to try to get Digirig to connect to my FT-818ND via WSJT-X (version 2.6.1) but have had no success. I am using a MacBook Pro (Ventura 13.7.2) and have had no trouble using the same computer and same Digirig module (but different cables, of course) to connect to my older Kenwood TS-450S and can run FT8 via the same version of WSJT-X.
I have set everything up how I believe it should be set up in the “Radio” tab but when I try “Test CAT”, the Transmit/Busy light on the radio turns red and the radio seems to change bands for a moment or so then I receive the below error:
Hamlib error: rig.c(2135):rig\_get\_freq returning2(-8) Protocol error

I have tried different combinations of settings (/dev/tty.SLAB\_USBtoUART as well as /dev/tty.usbserial-144420 and various others depending on which USB port I am using) and made sure the baud rate matches what is set in my radio. Any help anyone could provide would be greatly appreciated. Below is a screenshot of my settings in case anyone needs them.
I have looked through this forum and it seems what has worked for others has not worked for me. If anyone has any suggestions, I would greatly appreciate it. I would love to use this setup as a QRP FT8 rig. Thank you in advance for all your help!

FT-818 uses logic levels of the serial port. If your Digirig is configured for RS-232, then you’ll need to reconfigure Digirig, use this Digirig without CAT control (rig=none) or get another Digirig preconfigured for correct levels.

Thank you for the quick reply. I didn’t realize when I purchased the Digirig module for my Kenwood TS-450S that there were different configurations for the module itself (I incorrectly assumed the cables were the only difference). Just before I saw your reply, I stumbled upon a page on your site about the solder pads on the Digirig board that could be altered depending on intended use. I have included the URL to that page here in case anyone ever needs to reference it as I did:
> **[Understanding Rig Control Options – digirig](https://digirig.net/understanding-rig-control-options/)**
I ended up purchasing a second unit just now (one already configured as a logic levels module) so I can use different modules for both transceivers without having to alter one of them. The new unit is set to arrive in two days and I will update this thread once the new one arrives and confirm it is working in case anyone else ever runs into this same scenario.
Thank you again for your help!

Denis (K0TX) was spot on and correct above when he said I needed a different module (or needed to configure mine differently). I should have paid closer attention to different module types based on what transceiver they are to be used with. Thank you for your quick help, Denis and for a wonderful product!
