General Information

MESR 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. The easy to use software is designed for Windows 2000, 2003 Server, XP and Vista and 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. MESR9xx gateways are built for use in 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. An external power supply, sold separately, is required. The photograph above is an MESR922T gateway. The MESR92x units have an additional Ethernet port which 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. MESR90x units have one Ethernet port. B&B Electronics' Vlinx™ is you number one choice for Ethernet to Serial conversion.
