NLY
)
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.
