KPC-9612 to 1200 baud Radio Cable
The next step in installing your KPC-9612 is to make the cable for the 1200 baud port (port 1) of
your KPC-9612 to your radio. To transmit and receive data, you must make the following pin con-
nections from the DB-9 connector to appropriate pins on your radio.
Pin1 (TXA) Transmit audio – This pin connects the microphone input of your radio. TXA is the
data being sent by your TNC.
Pin 3 (PTT) Push-to-Talk – This pin connects to the PTT pin of your radio. The PTT signal causes
the radio to transmit when the TNC has data to send. This pin on your radio may have a
different name (e.g. STBY), but the function as described in your radio manual should indi-
cate that a ground on this pin will cause the radio to transmit.
Pin 5 (RXA) Receive audio -This pin normally connects to the external speaker jack on your radio.
The supplied 3.5 mm phone plug can be used by connecting the tip to pin 5 and the sleeve
to pin 6. In some radios, receive audio is also available through the microphone connector.
If your radio provides this feature, you will probably need to set the CD command to SOFT-
WARE since this audio is usually unaffected by the squelch or volume controls of your ra-
dio.
Pin 6 Ground -This pin connects to the ground pin of your radio. If your radio has a separate mic
ground and PTT ground, we recommend that you connect the PTT ground and do not con-
nect the mic ground.
The DB-9 connector supplied with your KPC-9612 is a male connector. When
you look at the connector from the back (the point you will solder the wires)
the pins are numbered as shown in the diagram.
After you have completed this cable, connect it to your KPC-9612 and secure
the DB-9 connector with the scres. Connect the other end to your radio.

Adjusting Receive Volume
To adjust the receiving volume on your 1200 baud radio properly, first turn on your computer, start
you terminal program and turn on the KPC-9612. Be sure the CD command in the KPC-9612 is set
to INTERNAL. Next turn on your radio and open the squelch control (fully counter-clockwise).
Slowly turn the volume up until the RCV LED on the KPC-9612 lights. Increase the volume control
slightly from this point. Next, turn the squelch control clockwise until the RCV LED goes out or until
the noise in your speaker stops. Your radio is now properly adjusted for receive volume.
