4-3 Operating Procedure for RS-422 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 RS-422 connector.
5 Set the rotary switches.

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 disconnect 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.
Note: Turn OFF the DC power supply before connecting the Units.
Set the mode switches to RUN mode.
Connect the connector for RS-422 communications.
Note: Be sure to connect terminating resistance to the last Communica-
tion Unit for RS-422.

Sets the CompoWay/F node number (0 to 31); set in combina-
tion with pin 4 of the DIP switch.
Sets the CompoWay/F communications mode (0 to F).
Sets the number of Sensors for communications (1 to 16). This
switch is enabled only when pin 3 of the DIP switch is OFF.
Note: If pin 3 of the DIP switch is ON, the number of Sensors is
set using a CompoWay/F message.

Method for setting number of Sensors connected
Use the rotary switch to register the number of Sensors.
Use CompoWay/F messages to register the number of Sensors.
Communications power supply is ON when the PWR indicator is
lit green.
Receiving serial communications when the RXD indicator is lit
yellow.
Transmitting serial communications when the TXD indicator is lit
yellow.
Operating normally when the U.ERR indicator is not lit (no Unit
error).
Sensors communicating when the SS indicator is lit green.
