Terminates the device. Required if the device is located at the end of
the RS-485 bus cable.
OFF
No termination
NOTE
User of the RS-485 data interface:
•
The relevant interface drivers for the device comply with the standard in accor‐
dance with RS-422 and RS-485.
•
This operating mode is only permitted if all connected devices use a correspond‐
ing RS-485 protocol.
•
This configuration is not permitted when using the standard data output and pro‐
tocol of the device. In case of doubt, contact SICK Service.
•
Activate the RS-485 data interface (“Bus” option) in the device using a configura‐
tion tool, e.g. the SOPAS ET configuration software.
