1.4.1 Installing the terminating resistor

If the CP valve terminal to be connected is situated at
the end of the field bus, a terminating resistor (120
Ohm, 0.25 Watt) must be fitted in the field bus socket.
If you are using T-adapters, we recommend that you fit
the terminating resistor to the unused output of the T-
adapter.
Terminating Crimp the wires of the resistor together with those of
resistor the field bus cable between the cores Data + (pin 4)
and Data - (pin 5) of the bus cable socket.
PLEASE NOTE
In order to guarantee reliable contact, we recom-
mend that the wires of the resistor and those of the
bus cable be crimped together in common connector
sleeves.
