Overview
The MGate W5108/W5208 series of gateways come with 1 or 2 serial
ports, making them an ideal choice for connecting Modbus/DNP3 serial
devices to a wireless LAN. With IEEE 802.11a/b/g/n support, you can use
fewer cables in difficult wiring environments, and for secure data
transmission, the MGate W5108/W5208 series gateways support
WEP/WPA/WPA2. The gateways’ rugged design makes them suitable for
industrial applications, including oil & gas, power plant, process
automation, and factory automation.

Hardware Introduction
As shown in the following figures, the MGate W5108 has 1 DB9 port for
transmitting serial data, and the MGate W5208 has 2 DB9 ports for
transmitting serial data. The MGate W5108/W5208 gateways come with 2
kV serial port isolation protection built in.

Hardware Installation Procedure
STEP 1:
After unpacking the unit, connect the power supply to the unit.
STEP 2:
Use an Ethernet cable to connect the unit to the
network.
STEP 3:
Connect your device to the desired port on the unit.
STEP 4:
Place or mount the unit. The unit may be placed on a
horizontal surface such as a desktop, or mounted on the wall.
Wall or Cabinet Mounting
T
wo metal plates are provided for mounting the unit
on a wall or inside a cabinet. Attach the plates to the
unit
’s rear panel with screws. With the plates
attached, use screws to mount the unit on a wall.
For each screw, the head should be 6.0 mm
or less in
diameter, and the shaft should be 3.5 mm or less in
diameter.
Termination Resistor and Adjustable Pull High/Low Resistors
In some critical environments, you may need to add termination resistors
to prevent the reflection of serial signals. When using termination

resistors, it is important to set the pull high/low resistors correctly so that
the electrical signal is not corrupted. The MGate W5108/W5208 uses DIP
switches to set the pull high/low resistor values for each serial port.
To add a 120 Ω termination resistor, set switch 3 on the port’s
assigned DIP switch to ON; set switch 3 to OFF (the default setting) to
disable the termination resistor.
To set the pull high/low resistors to 150 KΩ, set switches 1 and 2 on
the port’s assigned DIP switch to OFF. This is the default setting.
To set the pull high/low resistors to 1 KΩ, set switches 1 and 2 on
the port’s assigned DIP switch to ON.

Software Installation Information
To configure your MGate W5108/W5208, connect the gateway’s Ethernet
port directly to your computer’s Ethernet port and then log in from a web
browser. The default IP address is 192.168.127.254. The MGate supports
two types of accounts: admin and user. The admin account can modify
all settings, whereas the user accounts can only view settings. The
default password for the admin account is “moxa”.
If you forget the modified IP address of the gateway or cannot log in to
the gateway via a web browser for any reason, you can access the
gateway via a direct Ethernet cable connection using the Device search
utility to search for the gateway.
To install Device Search Utility (DSU), insert the MGate
Documentation and Software CD into your PC’s CD-ROM drive, and
then run the following setup program to begin the installation process
from the “Software” directory:
dsu_setup_[Version]_Build_[DateTime].exe
The filename of the latest version may have the following format:
dsu_setup_Verx.x.x_Build_xxxxxxxx.exe.
For detailed information about DSU, refer to the MGate W5108/W5208
User’s Manual, which can be found in the “Document” directory.
