Connecting the Transceiver Interface
Unbalanced Interface (TB2)
To connect an unbalanced interface:
1. Connect the PTT relay COM output (TB2 pin 1) to TB10 - Ground.
2. Connect the PTT relay N.O. output (TB2 pin 2) to the transceiver and PTT input.
3. Connect the Carrier detect ground (TB2 pin 10) to the transceiver’s ground.
4. Connect the Carrier detect (TB2 pin 9) to the transceiver’s carrier detect output.
Jumper the unit to accept either active low or active high carrier detect. If the carrier
detect is not available, jumper the unit for VOX.
5. If other equipment is using this transceiver, connect its transmit audio to TB2 pin4.
When the SS2000+ is transmitting, it interrupts this TX audio.
6. Connect the Transmit audio Hi output (TB2 pin 5) to the transceiver’s transmit audio
input.
7. Connect the Transmit audio Low (TB2 pin 6) to TB10 - Ground.
