Freddie,
The hardware configuration of Digirig only pertains to the serial port which is typically used for the CAT control of the transceiver. HTs don’t support CAT control so you can interfaces them with Digirig in any configuration. I would however recommend Default (logic levels) configuration with Baofengs because Digirig’s serial port can be used for programming of the radio with Chirp software. The programming cable for that is included in the kit for that radio.
