20.11 Setting up data interfaces
Serial interfaces on the TNC 640
The TNC 640 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.
Application
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
settings:
Set BAUD RATE
(baud rate no. 106701)
You can set the BAUD RATE (data transfer speed) from 110 to 115
200 baud.
