Hardware Connections
The FieldServer is connected to the GE PLC in one of two ways.
Almost every GE PLC has a RS-232 and RS-485 port. Possible cable configurations are
illustrated below.
A converter is required to connect between RS-232 and RS-485. An example of connection
configurations for the Model480TLED connector is depicted overleaf. Any equivalent connector
can be used.
