Now turn on the KPC-3 Plus.
AUTOBAUD
The first time your KPC-3 Plus is used, it runs an AUTOBAUD routine to assure that the
KPC-3 Plus baud is the same as that of whatever communication software you are
using.
The KPC-3 Plus' AUTOBAUD routine works as follows:
Step 1.
Step 2.
Step 3.
Step 4.
Technical note: The KPC-3 Plus' Baud is stored in the KPC-3 Plus as the value
of the ABAUD parameter, so when you use the KPC-3 Plus later, it will start with
that baud. This is made possible by an internal lithium battery supplied with the
KPC-3 Plus. Later, you can change the TNC baud if you want, as long as you
change your terminal's baud to match.
Step 5.
Hint: Do not confuse the KPC-3 Plus' baud for serial communication on the
computer port with the KPC-3 Plus' 1200-baud for communicating using the radio
port, which is connected by a custom-wired cabling to a transceiver.
Setting Basic Communication Parameters
There are several KPC-3 Plus settings in addition to ABAUD (baud) and MYCALL
(CALLSIGN) that you may wish to change, especially if parameter values in your KPC-3
Plus have been changed from their default settings. Even if you do not want to change
anything now, knowing about these parameters and knowing how to reconfigure your
KPC-3 Plus gives you more control in using it with HyperTerminal.
AUTOBAUD sends and resends the message ―PRESS (*) TO SET BAUD‖
at one baud after another. When the KPC-3 Plus' baud matches that of
your terminal program, you can read this on your screen; if the two rates
do not match, the message appears garbled, if it appears at all.
Any time while this message is being sent, whether it is readable or
garbled on your screen, enter the ―*‖ character (SHIFT+8 key
combination).
When the AUTOBAUD routine receives, the ―*‖ character from the serial
port, it uses that character to determine the baud in use.
AUTOBAUD then sets the KPC-3 Plus' baud (ABAUD) to match the baud
used.
Finally, AUTOBAUD sends a ―sign-on‖ message and asks for the user's
CALLSIGN, which will also be stored in the KPC-3 Plus and used until
changed. At this point, the user is ready to give commands to the KPC-3
Plus.
