2.7.2 Diagnosis/visualisation
The integrated RS232/485 interface serves for the connection of service tools (e.g. COM
-
BIVIS) and displays. Telegram DIN66019II is used as communication protocol.
The correct configuration and language file must be loaded for the operation with
COMBIVIS. The downlad can be done via the KEB website.

2.7.2.3 Connection of the RS485 interface
The following instructions must be observed in order to prevent interferences at
the RS485 interface:
•
use CAT 5 cable (in pairs, twisted and shielded cable)
•
ground at one side (prior at interference-free side)
•
Connect terminating resistors (120 Ω) at both ends on pair of wires of the
communication bus
If CAT 7 cable is used (by way of derogation from our recommendation) lay the
interior shield each to the transmitter.
