1.4.2 Installing the terminating resistor
Install a suitable terminating resistor in the socket of the
incoming RIO cable if the CP system to be connected
is at the end of a RIO line (see diagram). Seal the un-
used plug with a protective cap. In this way, you can
comply with protective class IP65.
1. Crimp the wires of the resistor together with those of
the incoming RIO cable between the cores S+ (pin
1) and S- (pin 3) of the RIO cable socket. In order to
guarantee reliable contact, we recommend that the
wires of the resistor and those of the incoming RIO
cable be crimped together in common cable end
sleeves.
Proceed
as follows

2. Fit the RIO cable socket onto one of the plugs.
3. Seal the unused plug with a protective cap.
