Digital Interface
Homemade 6 Pin-Din connector from the back up the radio for audio/data in and out to a TRRS connector on the PC headphone jack. CAT Control is conducted via USB B from the back up the radio to USB A on the PC. This uses the radios built in serial port for CAT / PTT Control. The driver for the Serial Port needs to be installed from here. (from the official Yaesu website) within the files section.
