(modem) unit.
12-4-1 Packet Communication Connections
When using this transceiver for packet communications, refer to the illustration
below and connect it to a TNC following these steps:
Connect an optional EDS 14 microphone/speaker plug conversion cable to the
earphone/microphone terminal at the top of this transceiver, and connect a TNC
(Terminal Node Controller) to the speaker terminal (using a 3.50 plug) and to the
microphone terminal (using a 2.50 plug).
·Adjusting the input level:
This transceiver doesn't have a function to adjust the
microphone input level. Adjust that level from theTNC, if necessary.
•Adjusting the output level:
