When the transceiver is set to DATA mode and you are operating packet communications using an external TNC 
(Terminal Node Controller), perform the connections as below.

Use the ACC2 connector to connect with an external TNC. Connect the external TNC modulation output line to 
pin 11 (ANI) of the ACC2 connector, demodulation input line to pin 3 (ANO) of the ACC2 connector, and transmit 
control (PTT) line to pin 13 (PKS) of the ACC2 connector.

◆

  Do not share a single power source between the TNC and the transceiver.

◆

  Keep as much space as possible between the transceiver and computer, and between the TNC, to prevent the transceiver from picking 

up noise.
