A-2-6 Hardware Specifications of
the Distributed Sensor Unit
This switch sets the node address that the E3NW-DS will use on the DS-Bus network between Units.
The setting range is from 1 to 8. (Default setting: 1)
If you are going to connect more than one Distributed Sensor Unit to the Sensor Communication Unit,
set the node address for each Distributed Sensor Unit to consecutive numbers starting from 1.
Precautions for Correct Use
• The unit address switch setting is read only once when the power supply is turned ON. Any
change that is made after the power supply is turned ON will not take effect until the power
supply is turned ON again.
• The Distributed Sensor Units will not operate properly if the same unit address is set more
than once.
This switch turns ON and OFF the communications terminating resistance on the Inter-Unit DS-Bus
network. Turn ON the switch on the Distributed Sensor Unit at the end of the network and turn OFF the
switch on the other Distributed Sensor Units.
