MESR Modbus Gateways bridge devices on Modbus serial networks (RS232, RS-422 or RS-485) with those on Modbus TCP networks, allowing
seamless integration. Serial ports can be accessed over a LAN or WAN
using Direct IP Mode connections. Supporting up to 16 masters and 32
slaves, these gateways feature autodetecting10/100 copper and fiber
optic options. Easy-to-use software is designed for Windows 2000, 2003
Server, XP, Vista, 2008 Server and Windows 7. 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 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 your number one choice for Ethernet to Serial
conversion.
