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. MESR400 models are available for 10/100 RJ-45 copper or Single-mode/Multi-mode optical fibre networks. The MESR400 series supports up to 16 Modbus masters and 32 Modbus slaves.

The easy to use software is designed for Win XP, Vista, Win 7 and Windows 2003/2008 Server and features Modbus messaging priority control and management through multiple TCP/ IP client sessions. Serial data rates up to 230 kbps ensure maximum network flexibility. 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. UL Class 1/Division 2 certification ensures MESR gateways are built for hazardous industrial environments.

MESR400 series gateways operate from a 10VDC to 48VDC power source and can be powered via a barrel connector or a terminal block. An external power supply is required. All MESR400 models feature a slim IP30 DIN rail mountable case.
