12.7 Setting the Data Interfaces

Serial interface on the TNC 320

The TNC 320 automatically uses the LSV2 transmission protocol for
serial data transfer. The LSV2 protocol is permanent and cannot be
changed except for setting the baud rate (machine parameter
baudRateLsv2

). You can also specify another type of transmission

(interface). The settings described below are therefore effective only
for the respective newly defined interface.

Function

To set up a data interface, select the file management (PGM MGT) and
press the MOD key. Press the MOD key again and enter the code
number123. The TNC shows the user parameter GfgSerialInterface,
in which you can enter the following settings:

Setting the RS-232 interface

Open the RS232 folder. The TNC then displays the following settings:

Setting the baud rate (baudRate)

You can set the BAUD RATE (data transfer speed) from 110 to 115 200
baud.

Set the protocol (protocol)

The data communication protocol controls the dataflow of a serial
transmission (comparable to MP5030).
