RS-232 Serial Port

RS-232 is used to configure the EGX200 network parameters, and also can be used
for serial communication using Modbus RTU. The EGX200 RS-232 port uses a
standard DB9 male connector. The following table shows the typical serial RS-232
connector pinout.

COM 1 and COM 2 LEDs

One set of LEDs is provided for each COM port. A yellow LED illuminates when the
corresponding COM port is receiving data (Rx). A green LED illuminates when data on
the corresponding COM port is transmitted (Tx). Also, above the COM 2 Rx and Tx
LEDs, a third LED (green) illuminates steadily when COM 2 is selected to be active for
RS-485 communication. The COM 2 Tx and Rx LEDs behave the same way when
used for either RS-485 or RS-232 communication.
