MESR9xx Modbus Gateway Features
•
Four series models
•
MESR901-x (single serial port, single Ethernet Port)
•
MESR902T-x (two serial ports with pluggable terminal blocks, single Ethernet
port)
•
MESR921-x (single serial port, two Ethernet Ports)
•
MESR922T-x (two serial ports with pluggable terminal blocks, two Ethernet
Ports)
•
On models with two Ethernet Ports, the second port is an Ethernet pass-
through port. This port functions much like an unmanaged switch.
•
Fiber models available for each of the above series
