10.5 Setting up data interfaces
Serial interfaces on the TNC 620
The TNC 620 automatically uses the LSV2 transmission protocol
for serial data transfer. All parameters of the LSV2 protocol are
invariably fixed except for the baud rate in the machine parameter
baudRateLsv2 (no. 106606).
When user administration is active, you can set up
only secure network connections via SSH. The control
automatically disables the LSV2 connections via the
serial interfaces (COM1 and COM2) and the network
connections without user identification.
Application
The machine parameter RS232 (no. 106700) allows you to define
another transmission type (interface). The settings described below
are effective only for the respective newly defined interface.
To set up a data interface:
Press the MOD key
Enter the code number 123
Define an interface in the machine parameter
RS232 (no. 106700)
Setting the RS-232 interface
To set up the RS 232 interface:
Open the RS232 folder
The control displays setting options with the following machine
parameters.
Set BAUD RATE
(baud rate no. 106701)

Enter a value between 110 and 115,200 baud.
