 Terminating Resistor Selection㻌
㻌
This function selects the terminating resistor for the sensor head connecting
to the host device over RS-422/485.
Be sure to select R3 if the system is connected to RS-422 equipment.
If a number of sensor heads are connected to RS-485 equipment, set R3 for the
terminating sensor and the rest of the sensors to OFF.
* The communication of the system, if unstable, may be improved by selecting R1
or R2.
