Setting up the TNC parameters

Setting the serial port is made via the Parameters/Setup dialog box under Terminal. First

check the TNC Enabled option then read the manual of your controller (…) to determine

parameters such as : speed - parity - data bits - stop bits. It is best to choose a high

speed baud rate such as 9600 or more to avoid the slowing down of the communication loop

with the transceiver.

An important parameter is the command signal used by your TNC to switch to the command

mode : check < CTRL C> for TNC 2, PK232, KAM ; check < Escape> for DK9SJ's modems

(TNC2S/H/3S… with TF Eprom).

In some cases you may have to check Add LF to automatically add a Line feed (LF) after a

carriage return (CR) ; please check this option only if frames are not properly displayed.

Priority to CAT is usually NOT checked. In some rare cases (probably with some older

transceivers operating at slow speed), checking Priority to CAT may increase the fluidity of

CAT control and the stability of the software : communications with the TNC are then

processed only after all data coming from the transceiver are received. Please note, in case of

this option is checked, opening the terminal window is not possible without opening the

monitoring window !

From the Preference submenu, under Terminal, You also have to choose between the DX

Cluster (default) and Clusse Dx Cluster formats for the DX spots. Be sure to check the right

option.

Troubleshooting

Most problems are coming from a wrong speed (Setup) or from a wrong mode (TRX-Manager

doesn't support any Host mode). Read carefully the manual of your TNC ... Try to increase the

speed to the maximum available value and disable the Autobaud mode on the TNC.
