Serial port configuration
RME2-AI-IA3serial port can be used in Gateway mode, allowing access to a Modbus serial
device (RTU or ASCII) from Ethernet in Modbus TCP.
This configuration is done from the menu "Configuration -> Port A".
If this option is enabled, queries in Modbus TCP to read the device analog inputs must be
made exclusively to the Modbus ID configured as "Internal Memory Modbus ID".
If this option is not enabled, device can respond to any Modbus TCP ID.
By enabling the use of the serial port, the device allows you to configure basic parameters:
