The following instructions must be observed to prevent malfunctions at
the RS485 interface:
• Use CAT 5 cable (in pairs, twisted and screened cable)
• Ground to one side (prior to the lower interference side)
• Attach terminating resistors of 120 Ω to both ends of the bus
If CAT 7 cable is used (by way of derogation from our recommendation) lay the
interior shield each to the transmitter.
If malfunctions still occur, it is possible to use a biasing. However, this shall be
done only once at the bus (preferably at the master).
