Additional terminating
resistor on the MIQ/
Blue PS
An additional terminating resistor is only required if, except in the MIQ/
Blue PS, no other terminator switch is available on the IQ S
ENSOR N ET
island. The terminating resistor is connected to one of the three SEN-
SORNET connectors (Fig. 3-4). The terminating resistor must bridge
the two outside terminals of the SENSORNET connector. The SEN-
SORNET connector can still be used to connect a sensor.
