Setting up your KPC-9612
Power Cable
Using hookup wire, connect a 12 VDC power supply to the 2.1 mm plug (supplied) by connecting
the positive wire to the center of the plug and the negative wire to the sleeve. Insert the power
plug into the power jack at the rear of the KPC-9612.
KPC-9612 to Computer Cable
To connect your KPC-9612 to your Computer you will need to use a modem cable. The KPC-9612
requires a 25-pin male DB connector and your Computer will normally require either a 25-pin or a
9-pin female connector. As shipped from the factory, the KPC-9612 is configured so you may use a
25-wire cable. See the hardware section for details on reconfiguring the 25-pin serial connector on
the KPC-9612.
Connect your serial cable to the 25-pin connector on the rear of the KPC-9612, and the female
connector to your Computer serial port (COM port). We suggest you connect this cable to COM1 or
COM2 on your Computer. The Pacterm program used in conjunction with the examples in this man-
ual supports only these two COM ports.
For connection to other types of computers, refer to their software and hardware manuals. The
KPC-9612 will communicate with a terminal with a minimum of three wires connected (Txd, Rxd,
and SG). Your Software (terminal program) may require that other wires be connected. Refer to
the hardware section of this manual for a complete description of the connections in the KPC-
9612.
