Serial interfaces on the TNC 620
The TNC 620 automatically uses the LSV2 transmission protocol
for serial data transfer. The LSV2 protocol is fixed as a default
and cannot be changed except for setting the baud rate (machine
parameter baudRateLsv2, no. 106606). You can also specify
another type of transmission (interface). The settings described
below are therefore effective only for the respective newly defined
interface.
Application
To set up a data interface, select the file manager (PGM MGT)
and press the MOD key. Press the MOD key again and enter
the code number 123. The TNC shows the user parameter
GfgSerialInterface (no. 106700), in which you can enter the
following settings:
Setting the RS-232 interface
Open the RS232 folder. The TNC then displays the following
settings:
Set BAUD RATE
(baud rate no. 106701)
You can set the BAUD RATE (data transfer speed) from 110 to 115
200 baud.
