Overview
The MGate W5108/W5208 series of gateways comes with one or two
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 of gateways
supports WEP/WPA/WPA2. The gateways’ rugged design makes them
suitable for industrial applications, including oil and gas, power plant,
process automation, and factory automation.
Package Checklist
Before installing the MGate W5108/W5208 gateway, verify that the
package contains the following items:
•1 MGate W5108 or W5208 gateway
•1 antenna
•Quick installation guide (printed)
•Warranty card
Optional Accessories
•Mini DB9F-to-TB Adapter: DB9-female-to-terminal-block adapter
for RS-422/485 applications
•WK-51-01: Wall-mounting kit
Notify your sales representative if any of the above items are missing
or damaged.
Hardware Introduction
As shown in the following figures, the MGate W5108 has one DB9 port
for transmitting serial data, and the MGate W5208 has two DB9 ports
for transmitting serial data. The MGate W5108/W5208 gateways come
with 2 kV serial port isolation protection built in.

Reset Button—Depress the Reset button continuously for 5 sec. to
load factory defaults.
The reset button is used to load factory defaults. Depress the reset
button for five seconds using a pointed object, such as a straightened
paper clip. Release the reset button when the Ready LED stops blinking.

Hardware Installation Procedure
STEP 1:
After unpacking the unit, connect the power supply to the
unit.
Make sure the adapter is connected to an earthed
socket.
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
Two 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. The heads of the screws should be 5
to
7 mm in diameter, the shafts should be 3
to 4
mm in diameter, and the length of the screws
should be more than 10.5 mm.
For each screw, the head should be 6 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-ohm 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 kilo-ohms, 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 kilo-ohm, 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.
Default IP address: 192.168.127.254
Default account: admin
Default password: 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 (DSU) to search for the gateway.
To install the DSU, download it from Moxa’s website at
http://www.moxa.com.
