Serial interfaces on the TNC 620

The TNC 620 automatically uses the LSV2 transmission protocol

for serial data transfer. The LSV2 protocol is prescribed and cannot

be modified apart from setting the baud rate (machine parameter

baudRateLsv2, no. 106606). You can also define another type of

data transfer (interface). The settings described below are therefore

effective only for the respective newly defined interface.

To set up a data interface, press the MOD key. Enter the code

number 123. In the CfgSerialInterface (no. 106700) machine

parameter, you can enter the following settings:

Setting the RS-232 interface

Open the RS232 folder. The control then displays the following

Set BAUD RATE

(baud rate no. 106701)

You can set the BAUD RATE (data transfer speed) from 110 to 115
