MESR92x 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. 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 autodetecting 10/100
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. MESR92x
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 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.
