    Cables provided with the TNC are shielded. If you decide to use other cabling, be certain it is also shielded. We do not recommend the use of unshielded RS-232 ribbon cable in the ham shack environment. Pin 25 of the DB-25 connector on the KAM, KPC-2 KPC-2400 has 12 volts and should never be connected to your terminal or computer port.

The following chart shows what pins are used in the TNC by name and number and the corresponding pin to connect to for the most commonly used computer connectors. A general rule, if you have a computer not covered here that has a serial data port, wire pins of the same name together.

    IN CASE OF DIFFICULTY In Case of Difficulty Kantronics TNCs are manufactured to very stringent quality standards. If you have followed the in- stallation procedures outlined in this manual, it is highly unlikely that you will encounter a failure. If you do have difficulty, use the procedures described in this section to assist in isolating and cor- recting the problem.
