Step 1. Open the KPC-3 Plus case
Step 2. Confirm that a battery connector (pig tail, snap connector) has been installed
or install one, as described above, if needed. If there is a protective clip over
the battery connector, remove it
Step 3. Attach a 9-V battery
Step 4. Close the case
Step 5. Press the power switch on the front panel of the KPC-3 Plus to turn your
KPC-3 Plus ON, confirm that the power indicator next to the power switch
goes on, and then press the power switch again to turn the power OFF
If the power indicator (LED) does not go on as expected, the unit may be defective, so
you should check with your dealer.
This concludes the installation of power to your KPC-3 Plus. The next topic is
connecting your KPC-3 Plus to your computer.
Connect your KPC-3 Plus to Your Computer
Your KPC-3 Plus and your computer communicate with each other via a serial
communication cable connecting the KPC-3 Plus‘ ―Computer‖ port and a serial (COM)
port on your computer. This connection is shown in the diagram on page 33.
Your Serial Communication Cable
The serial cable needed to connect your KPC-3 Plus to your computer (a standard off-
the-shelf, RS232 modem cable) is not supplied with the KPC-3 Plus. You will need to
purchase one, or construct one.
Note: You may construct your own cable, using wiring instructions given below.
The two options, purchasing your cable or making it, are covered next.
Purchase Your Serial Cable
To purchase your cable (from your local amateur radio dealer or computer dealer):
specify that you need a standard serial modem cable (RS232), with high quality
shielding (see Note 2 in the Radio Frequency Interference Statement section),
less than 3-m in length, and at least 9 wires connected,
specify that one connector be a male DSUB-25 connector (to connect to your
KPC-3 Plus‘ female ―Computer‖ port) and the other connector be a female
DSUB-9 or DSUB-25 connector (depending upon whether your computer‘s serial
(COM) port has a male DSUB-9 or DSUB-25 connector)
