About MESR424 Modbus Gateways
MESR424 Modbus Gateway s connect Modbus networks (RS-232, RS-422 or RS-485)
to Ethernet networks, allowing the Modbus network to become a node on the network.
The serial ports can be accessed over a LAN/WAN using Direct IP Mode connections.
MESR424 Modbus Gateway
s feature 10BaseT or 100BaseTX copper network media and
fiber optic media options, depending on the model. MESR424 Modbus Gateways are
built for use in industrial environments, featuring an IP30 approved slim line DIN rail
mountable case. They operate from a range of DC power supply voltages and feature
pluggable terminal block power connectors. An external power supply, sold separately, is
required. MESR424 Modbus Gateways have an additional Ethernet port which functions
much like an Ethernet Switch.
MESR424 Modbus Gateway Model Numbering
MESR424 Modbus Gateway s are a growing family of products. Models are available
with DB9 or Terminal Block connections. Network connection options include
10BaseT/100BaseTX copper or several different fiber optic options.
