PREFACE
THIS SECTION CONTAINS IMPORTANT INFORMATION – PLEASE READ CAREFULLY
Your Kantronics All Mode Communications Terminal (KAM) is a state of the art device. It has
been carefully designed, assembled and tested to meet your demanding specifications. We do
need your warranty registration on file. Please take a moment to complete this card and return it
to us.
The KAM is a Kantronics hardware and software design incorporating the AX.25 Version 2 Level
2 Packet protocol as adopted by the American Radio Relay League. This Operator’s Manual con-
tains information from earlier KPC-1 and KPC-2 manuals, modified as appropriate. In addition,
Kantronics acknowledges the use of material from the original Tucson Amateur Packet Radio Cor-
poration (TAPR) TNC-1 manual granted by OEM agreement.
We have attempted to make this Operator’s Manual technically and typographically correct as
of the date of the current printing. Production changes to the KAM my include errata or addendum
sheets as required. We solicit your comments and/or suggested corrections. Please send to Kan-
tronics Inc., 1202 E 23
rd
St., Lawrence, Ks 66046.
We have attempted to organize the manual in the most logical sequence to simplify installation
and operation. Due to the complexity of the KAM, you may wish to save the "exotic" parts until lat-
er. Refer to those sections covering multi-connect, gateway and simultaneous HF/VHF packet oper-
ation after you have the KAM installed and operating.
Throughout the manual we will use the terms "enter", "return" or "carriage return" inter-
changeably. In addition, the symbol <CR> is used to signify the action of operating the key which
causes entry of a carriage return.
PRECAUTIONS
CAUTION: The KAM is grounded through its connections to your transceivers. Make sure your
transceivers are properly grounded and your computer has equal ground potential. Follow the
grounding instructions in your transceiver manual.
Cables provided with the KAM Communicator are shielded. If you decide to use substitute ca-
bling, be certain it is also shielded. We do not recommend the use of RS-232 ribbon cable in the
ham shack environment.
