15 CONNECTING PERIPHERAL EQUIPMENT

MCP AND TNC

Use the ACC 2 connector to connect the input/output lines from a Terminal Node Controller (TNC) for Packet operation, a Multimode Communications Processor (MCP) for operation on Packet, PacTOR, AMTOR, G-TORTM, or FAX, or from a Clover interface. Also use the ACC 2 connector to connect SSTV and phone patch equipment.

•Connect the TNC or MCP to the ACC 2 connector using a cable equipped with a 13-pin DIN plug.

•Connecting the TNC or MCP to a personal computer or dumb terminal requires an RS-232C cable.

Note:

◆Do not share a single power supply between the transceiver and the TNC or MCP. Keep as wide a separation as possible between the transceiver and the computer as practical to reduce noise-pickup by the transceiver.

◆The output voltage of Pin No. 6 (SMET) is not 0 V even when no signal is present. In addition, the output voltage differs between FM (approx. 2.8 ~ 3.8 V) and other modes (approx. 0.5 ~ 3.8 V). When connecting this pin to peripheral equipment such as a personal computer, the input impedance of that equipment must be higher than 1 MΩ. If you connect to equipment having lower impedance, the S-meter will not give accurate readings.

•

Connect to TNC or MCP squelch control pin for digital operation.

 

 

•

Prevents the TNC from transmitting while the receiver squelch is open.

 

 

•

Squelch open: Low impedance

 

 

•

Squelch closed: High impedance
