Connect the MT1200 to Your Transceiver
The connections required between the MT1200 and your transceiver, are transmit
audio, receive audio, PTT and ground. The radio port of the MT1200 is the configured
the same as the radio port of our other TNC models, such as the KPC-3 Plus.
There are several sources of ready-made cables for this connection, or you may wish to
make up your own cable.
If you wish to construct your own cable, use the following guidelines.
Parts needed for assembling a TNC to Radio cable
The following parts (shipped with your MT1200 unless otherwise noted) are needed for
constructing the cable assembly that will connect your MT1200 and your transceiver:
•
DSUB-9 connector kit (including hardware), for the MT1200’ “Radio” port end of
the cable.
•
A 3-foot (0.91 m) length of 5-conductor shielded cable,
•
A suitable connector or connectors for the radio end of the cable. Typically, the
microphone connector (i.e., the Mic plug) and external speaker connector (plug),
or a connector (plug) for the auxiliary input/output jack on the transceiver.
Preparing the Transceiver Cable Assembly
This section gives instructions for how to assemble the cable assembly needed to
connect your transceiver to your MT1200, starting with the wiring requirements.
Wiring Directions (Connecting MT1200 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 MT1200. 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.
