You can also install the required terminating
resistor (120 Ohm, 0.25 Watt) economically in
the socket of the field bus cable. To do this
proceed as follows:
1. Connect the wires of the resistor together with
those of the field bus cable between the
wires Data + (pin 4) and Data - (pin 5) of the
bus cable socket.
PLEASE NOTE
To guarantee reliable contact, we recommend
that the wires of the resistor and those of the
bus cable be crimped together in common end
sleeves.
2. Fit the bus cable socket to the field bus plug.
