CONNECTING TO A TNC (E MARKET MODELS ONLY)

To connect an external TNC to the transceiver, use an

optional PG-5A cable. The DATA connector on the rear

of the transceiver mates with the 6-pin mini-DIN plug on

this cable.

Note:

◆If the external TNC has a common pin for 1200 bps and 9600 bps

data output, connect this pin to the DATA connector PR9 pin.

Shorting the PR9 and PR1 pins will cause the TNC to malfunction.

◆Adjust the transceiver data communication speed (1200 bps or

9600 bps) as necessary {page 58}.

◆If DC voltage is input to the PR1 pin, the external TNC may not

function. If this problem happens, add a 10 µF capacitor between

the PR1 pin and the TNC. Be careful with the polarity of the

capacitor.
