Switch setting Function
ON Terminates the RS-422 receiver in the device to improve the noise ratio
on the line.
OFF No termination
NOTE
User of the RS-422 data interface:
•
The relevant interface driver for the device complies with the standard in accor‐
dance with RS-422.
•
The connection shown above is configured for operation of the host with perma‐
nently activated drivers (often described as “RS-422 operation”).
•
Activate the RS-422 data interface (“Point-to-Point” option) in the device with a
configuration tool, e.g. the configuration software SOPAS ET.
