1. Overview The Modbus gateways IE-GW-MB-2TX-1RS232/485 and IE-GWT-MB2TX-1RS232/485 (equipped with 1 serial port and 2 Ethernet ports) convert between Ethernet-based Modbus TCP and serial-based Modbus ASCII/RTU protocols. They can be used to allow Ethernet masters to control serial slaves, or to allow a serial master to control Ethernet slaves. Up to 16 TCP masters and 31 serial slaves can be connected simultaneously. 2.

DIP switches for RS422/485 line termination and setting pull high/low resistors The DIP switches (SW1) are located inside of the housing behind the screwable side-gate. To add a 120 Ω termination resistor, set switch 3 to ON. To disable the termination resistor set switch 3 to OFF (default setting). To set the pull high/low resistors to 150 KΩ, set switches 1 and 2 to OFF (default setting). To set the pull high/low resistors to 1 KΩ, set switches 1 and 2 to ON. DIP switch 4 is reserved for future use.

5. Software-based Device Configuration The Modbus TCP/RTU Gateway can be configured via one of the 2 Ethernet ports by Integrated Webinterface Telnet Console or by PC-based utility “Modbus Gateway Administrator” Accessing the Web interface: The Web interface can be accessed via IP address 192.168.1.110 and subnet mask 255.255.255.0 (Factory default value). Connect the PC to one of the both Ethernet ports and set the PC’s IP address to a free one of network range 192.168.1.0 / 255.255.255.
