PRECAUTIONS
The TNC is grounded through its connections to your transceiver. Make sure your trans-
ceiver is properly grounded and your computer has equal ground potential. Follow the
grounding instructions in your transceiver manual.
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 and KPC-2400 has 12 volts and should
never be connected to your terminal or computer port. Pin 18 in the KPC-2 is used by fac-
tory personnel only. Under no circumstances should you connect this pin to your terminal
or computer output port.
