Product FEaturEs
MESR900 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 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.
