The MESR400 series Modbus Gateways bridge devices on Modbus serial networks (RS-232, RS-422 or RS-485) with those on Modbus TCP networks, allowing seamless integration. The serial ports can be accessed over a LAN or WAN using Direct IP Mode connections.
Supporting up to 16 masters and 32 slaves, the gateways feature autodetecting10/100 copper and fiber optic options. They are available from Interworld Electronics & Computer Industries.
The easy to use software is designed for Win XP, Vista, Win 7 and Windows 2003/2008 Server, features Modbus messaging priority control and allows management through multiple TCP/ IP client sessions. Serial data rates up to 230 kbps ensure maximum network flexibility.
Class 1/Division 2 MESR gateways are built for industrial environments, featuring a slim IP30 DIN rail mountable case. They operate from a range of DC power supply voltages and have pluggable terminal block connectors.
MESR400 series gateways can be powered via a barrel connector or a terminal block. (An external power supply is required; sold separately.)
An additional Ethernet port functions much like an Ethernet switch, allowing pass-through connectivity for other Ethernet devices. This port can also be used to “daisy chain” multiple gateways.
