4.5.2 Operation mode
The Modbus Gateway makes connected Serial equipment become IP-based. That also makes them able to connect to a
TCP/IP networking immediately. The Modbus Gateway allows traditional Computer/Client COM ports access to a serial
equipment anywhere on the Ethernet LAN network.
This operation mode can be set up as Disable, RTU Slave/Master and ASCII Slave/Master. The operation mode screen in
