NOTE
Use of the RS-422 data interface:
•
The relevant interface drivers for the device comply with the standard for RS-422 and RS-485.
•
Activation of the interface in the device with the SOPAS ET configuration software (point-to-point).
•
The connection shown above is configured for operation of the host with permanently activated drivers (often
described as “RS-422 operation”), i.e. not RS-485 bus operation.

NOTE
Use of the RS-485 data interface:
•
The relevant interface drivers for the device comply with the standard for RS-422 and RS-485.
•
This operating mode is only permitted if all connected devices use a corresponding RS-485 protocol.
•
Activation of the interface in the device with the SOPAS ET configuration software (point-to-point).
•
This wiring is not permitted in the standard data output/protocol for the device. In case of doubt, contact
SICK Service.
