Here’s the pinout for G90 connections:

The serial cable in this schematic confuses me as it appears to connect Tx on Digirig to Tx on the G90 and same for Rx. I assume the actual connections are Tx-\>Rx and Rx-\>Tx, but which is which on each end?

`RIG_` prefix in labels for audio and serial lines refers to the radio’s perspective to resolve ambiguity. Lots of schematics make it unclear if lines need to be crossed over or not.
