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!

Software Setup: Install Network EnablerAdministrator normally, and start it up. The software
will automatically scan for the cradle; when it is found, you will see a window on your screen as
shown below.
After the scan is completed, select the desired unit and open it up. It will show configuration screen
like below.
In this screen, you can setup many aspects of the cradle’s Ethernet behavior. The first thing to take note
is the “Modify” check box. This is a safety feature that prevents people from accidentally changing the
setup. You can view all setup information in detail with the box unchecked, but you cannot change
anything without checking the “Modify” box. To modify the setup information, check the “Modify”
box and the corresponding category will allow the setting to be changed. When done, click “OK” to save,
“Cancel” to abort.
When using this cradle with Multi-TCP, you need to have the unit set to TCP Server mode with port set
at 3000, and the proper/legal IP within your network. Then you may access the remote cradle unit from
your desktop with Multi-TCP by inputting the IP address of the cradle into Multi-TCP.
