Communication Connections and initial power application:
The examples shown in the power connection methods also indicated how the RS-485
communication lines are connected. Shown below is a typical connection for a Suprex Remote
and Central unit using one of the power connection diagrams.
With the units connected using A,B, or C power connections, turn on the power supply. Only power
and communications connections should be made at this point.
Data and I/O connections should be made after power and communication is verified.
Regardless of which connection method is used, a correctly wired and operating setup will have
these indications:
a. The Green power indicator will be illuminated.
b. The Diagnostic indicator LEDs will be flashing rapidly on both Central and Remote units.
Do not proceed further if this is not the case. Refer to the troubleshooting guide to correct any
problems.
