RS-422 Communication Unit Part Names and Functions
Note
1.
Do not turn ON the power to the Communication Unit when the Mobile
Console is connected. Communications will not be established with the
Sensors if the Mobile Console is already connected when the Unit power
is turned ON.
2.
Always set the Sensors to RUN mode when using the Fiber Amplifier Sen-
sor Communication Unit for RS-422. When other modes (SET or ADJ) are
set, the Fiber Amplifier Sensor Communication Unit cannot read or write
Sensor data.
3.
A Sensor communications error will occur under the following conditions
after the Mobile Console is connected with it’s power turned ON.
• When the power to the Mobile Console is turned OFF.
• When the Mobile Console is left idle while connected, causing the
power to automatically turn OFF.
• When the Mobile Console battery goes low, causing the power to turn
OFF.
Do not allow the above conditions to occur when using the Mobile Console,
or use the Mobile Console when problems will not occur even if a Sensor
communications error occurs.
