Connecting With A Personal Computer - Kenwood TM-D700A Instruction Manual

CONNECTING WITH A PERSONAL COMPUTER

Use a commercially available RS-232-C straight cable to
connect the transceiver to a personal computer. This
1
transceiver has a DB-9 male connector on the front of
the main unit.
Note: Turn OFF the transceiver power before making the connections.

To connect an external TNC to the transceiver, use an
optional PG-5A cable. The DATA connector on the front of
the main unit mates with a 6-pin mini DIN plug on this cable.

Note:
If the external TNC has a common pin for 1200 bps and 9600 bps
data input, connect this pin to the DATA connector PR9 pin. Shorting
the PR9 and PR1 pins will cause the TNC to malfunction.
If DC voltage is input to the PR1 pin, the external TNC may not
function. If this problem happens, add a 10 F capacitor between the
PR1 pin and the TNC. Be careful with the polarity of the capacitor.
