MR055 Ethernet Board
MR055
Ethernet Board is a specially design for MR350MKII and MR350TA
series.
The main function of the MR055 is to
network-enable
existing serial devices. Using the MR055 you
can add an Ethernet port practically to any serial device with RS232 interface, and communicate
with your serial device from any PC (or other device) to LAN.
If your LAN has a direct connection to the Internet, then you can access and control your serial
device from anywhere in the world!
