2-3 Operating Procedure for DeviceNet Communication Unit
Step Item
1 Mount the Communication Unit to
the DIN Track.
2 Connect the Fiber Amplifier Units
to the Communication Unit.
3 Set the Sensors to RUN mode.
4 Connect the DeviceNet communi-
cations connector.
5 Set the rotary switches.
6 Set the DIP switch.
7 Turn ON the DC power supply (V+,
V– DeviceNet communications
power supply).
8 Check the indicators.
9 Start communications.

Mount the Unit to the DIN Track. After mounting the Fiber Amplifier Units to the
DIN Track, connect the Units to each other.
Note: To remove the Units from the DIN Track, first slide the Units apart to dis-
connect them, and then remove the Units from the DIN Track.
Connect the Communication Unit to the Fiber Amplifier Units by sliding the
Communication Unit until the clips on the end are aligned and a "click" sound
is heard.
Set the mode switches to RUN mode.
Connect the DeviceNet Communications Connector.
Note: The DC power supply to the Communication Unit and all Fiber Amplifier
Units connected to it is supplied from the DeviceNet communications power
supply (V+, V–).
Two Sets the DeviceNet node address (0 to 63).

(Enabled when DIP switch pin 3 is OFF only.)
Note 1: When DIP switch pin 3 is ON, set the number of Sensors
connected using the Configurator or explicit messages.
Note 2: Fiber Amplifier Units (E3X-DA6TW, E3X-DA8TW) that are
allocated two unit numbers must be counted as two Units
when counting the number of Sensors.
