The transceiver is equipped with an accessory data port which is always a preferred option compared to interface via mic/speaker connections:
The 9600 baud Digirig audio cable will look like this:
DATA 2.5mm TRRS tip (Data input) → 3.5mm TRRS ring 1 (RIG_AFIN)
DATA 2.5mm TRRS ring (PTT) → 3.5mm TRRS ring 2 (RIG_PTT)
DATA 2.5mm TRRS sleeve (GND) → 3.5mm TRRS sleeve (GND)
SP 3.5mm TRRS ring (GND) → No Connection
SP 3.5mm TRRS ring (GND) → 3.5mm TRRS tip (RIG_AFOUT)
SP 3.5mm TRRS sleeve (GND) → 3.5mm TRRS sleeve (GND)
9600 baud audio path is also suitable for standard 1200 baud based digital modes.
NOTE for 9600 bps operation:
• If the transceiver does not transmit (the transmit indicator flashes or does not illuminate), the input level may be higher.
• If the re-try function is activated frequently, the input level may be lower.
Operation:
- Connect a TNC to the transceiver’s [SP] and [DATA] jacks.
- Set the operating frequency. Push and hold [LOW-DATA] for 1 sec. to select data mode.
• “DATA” appears.
• The microphone signals are cut from the modulation circuit while in data mode. - Control the transceiver from a personal computer, etc.
