Kantronics KPC–3 Plus User Manual page 44

What are the exact wiring requirements for connecting your transceiver to the
KPC-3 Plus, as determined by information given in this document and also by
requirements for your own particular make and model of transceiver (as
determined by the documentation for your transceiver)?
What are the steps used in constructing and connecting the cable assembly?
Once the cable is in place, how does one set the volume level of the transceiver
for optimal performance?
Parts for Connecting the KPC-3 Plus to a Transceiver
The following parts (shipped with your KPC-3 Plus unless otherwise noted) are needed
for constructing the cable assembly that will connect your KPC-3 Plus and your
transceiver:
DSUB-9 connector kit (including hardware), to make the DSUB-9 connector for
the end of the transceiver cabling that connects to the KPC-3 Plus' ―Radio‖ port
A 3-foot (0.91 m) length of 5-conductor shielded cable, to connect a user-
supplied microphone connector (i.e., the Mic plug) and/or a user-supplied
auxiliary connector (plug) or external audio connector (plug) for your transceiver
to the DSUB-9 connector supplied with your KPC-3 Plus
Preparing the Transceiver Cable Assembly
This section gives instructions for how to assemble the cable assembly needed to
connect your transceiver to your KPC-3 Plus, starting with the wiring requirements.
Wiring Directions (Connecting KPC-3 Plus and Transceiver)
You will need to determine which pins on your DSUB-9 connector will be wired to which
connections on your particular transceiver's microphone connector and speaker jack.
Wiring directions are covered after the following examples of typical transceivers,
including handhelds.
There are many different models of transceivers, each with their own exact
requirements for how they are to be connected to devices such as a KPC-3 Plus.
While the following examples will help, you will need to refer to your transceiver
documentation (or transceiver dealer) for exact instructions on which connections
you need to make as you wire your transceiver cable assembly.
Note: If you need further assistance on your radio cabling, contact the radio
manufacturer, your dealer, or a local amateur who has already installed a TNC.
Kantronics is not likely to have pin assignments for specific transceiver models.
The following diagrams, used for example only, show wiring connections between the
male connector for the KPC-3 Plus' ―Radio‖ port, and common transceivers (including
HTs) from three major manufacturers: Yaesu, Icom, and Kenwood.
