Hardware Installation Procedure
•Connect the power adapter. Connect the 12-48 VDC power line or DIN-rail power supply to the MGate
5114’s terminal block.
•Use a serial cable to connect the MGate to the Modbus RTU/ASCII or IEC 60870-5-101 device.
•Use an Ethernet cable to connect the MGate to the Modbus TCP or IEC 60870-5-104 device.
•The MGate 5114 is designed to be attached to a DIN rail or mounted on a wall. For DIN-rail mounting,
push down the spring and properly attach it to the DIN rail until it snaps into place. For wall mounting,
install the wall-mount kit (optional) first and then screw the device onto the wall.
The following figure illustrates the two mounting options:
Specifications
NOTE

microSD
The MGate 5114 provides users with an easy way to backup, copy, replace, or deploy. The MGate is
equipped with a microSD card slot. Users can plug in a microSD card to backup data, including the system
configuration setting, and system data log.
First time using the MGate gateway with a new microSD card
1. Format the microSD card as FAT file system through a PC.
2. Power off the MGate and insert the microSD card (ensure that the microSD card is empty).
3. Power on the MGate. The default settings will be copied to the microSD card.
4. Manually configure the MGate via web console, and all the stored changes will copy to the microSD card
for synchronization.
First time using the MGate with a microSD card containing a configuration file
1. Power off the MGate and insert the microSD card.
2. Power on the MGate.
3. The configuration file stored in the microSD card will automatically copy to the MGate.
Duplicating current configurations to another MGate gateway
1. Power off the MGate and insert a new microSD card.
2. Power on the MGate.
3. The configuration will be copied from the MGate to the microSD card.
4. Power off the MGate and insert the microSD card to the other MGate.
5. Power on the second MGate.
6. The configuration file stored in the microSD card will automatically copy to the MGate.
Malfunctioning MGate replacement
1. Replace the malfunctioning MGate with a new MGate.
2. Insert the microSD card into the new MGate.
3. Power on the MGate.
4. The configuration file stored on the microSD card will automatically copy to the MGate.

microSD card writing failure
The following circumstances may cause the microSD card to experience a writing failure:
1. The microSD card has less than 20 Mbytes of free space remaining.
2. The microSD card is write-protected.
3. The file system is corrupted.
4. The microSD card is damaged.
The MGate will stop working in case of the above events, accompanied by a flashing Ready LED and beeping
alarm. When you replace the MGate gateway’s microSD card, the microSD card will synchronize the
configurations stored on the MGate gateway. Note that the replacement microSD card should not contain
any configuration files on it; otherwise, the out-of-date configuration will copy to the MGate device.

3. Getting Started
Connecting the Power
The unit can be powered by connecting a power source to the terminal block:
1. Loosen or remove the screws on the terminal block.
2. Turn off the power source and then connect a 12–48 VDC power line to the terminal block.
3. Tighten the connections, using the screws on the terminal block.
4. Turn on the power source.
NOTE
The unit does not have an on/off switch. It automatically turns on when it receives power. The PWR LED
on the top panel will glow to indicate that the unit is receiving power. For power terminal block pin
assignments, refer to the Power Input and Relay Output Pinouts section in chapter 2.
Connecting Serial Devices
The MGate 5114 supports Modbus serial devices. Before connecting or removing the serial connection, first
make sure the power is turned off. For the serial port pin assignments, see the Pin Assignments section in
chapter 2.
Connecting to a Network
Connect one end of the Ethernet cable to the MGate’s 10/100M Ethernet port and the other end of the cable
to the Ethernet network. The MGate will indicate a valid connection to the Ethernet in the following ways:
•The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet network.
•The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet network.
•The Ethernet LED will flash when Ethernet packets are being transmitted or received.

Installing DSU Software
If you do not know the MGate gateway’s IP address when setting it up for the first time (default IP is
192.168.127.254); use an Ethernet cable to connect the host PC and MGate gateway directly. If you
connect the gateway and host PC through the same Ethernet switch, make sure there is no router between
them. You can then use the Device Search Utility (DSU) to detect the MGate gateways on your network.
You can download DSU (Device Search Utility) from Moxa's website: www.moxa.com.
The following instructions explain how to install the DSU, a utility to search for MGate 5114 units on a
network.
1. Locate and run the following setup program to begin the installation process:
dsu_setup_[Version]_Build_[DateTime].exe
This version might be named dsu_setup_Ver2.x_Build_xxxxxxxx.exe
2. You will be greeted by the Welcome window. Click Next to continue.
3. When the Select Destination Location window appears, click Next to continue. You may change the
destination directory by first clicking on Browse....
4. When the Select Additional Tasks window appears, click Next to continue. You may select Create a
desktop icon if you would like a shortcut to the DSU on your desktop.
5. Click Install to start copying the software files.
6. A progress bar will appear. The procedure should take only a few seconds to complete.
7. A message will indicate that the DSU is successfully installed. You may choose to run it immediately by
selecting Launch DSU.
8. You may also open the DSU through Start > Programs > MOXA > DSU.
The DSU window should appear as shown below.
Click Search and a new Search window will pop up.

Log In to the Web Console
Use the Web console to configure the MGate through Ethernet or verify the MGate’s status. Use a web
browser, such as Microsoft Internet Explorer or Google Chrome to connect to the MGate, using the
HTTP/HTTPS protocol.
When the MGate gateway appears on the DSU device list, select the gateway and right-click the mouse
button to open a web console to configure the gateway.
On the first page of the web console, enter admin for the default Account name and moxa for the default
Password.
When you log in the web console for the first time, a message will pop up. Emphasizing a higher security
level, we suggest you to change the password.
The password can be changed in the following path: System Management > Misc. Settings > Account
Management.

Quick Setup—Select Protocol
Then, you should select your devices' protocols on each side. After selection, the MGate will automatically
change to its proper role. For example, if the device is set as a IEC 60870-5-104 client, the MGate will then
automatically configure as a IEC 60870-5-104 server by itself. Regarding protocol configuration, refer to
chapter 4.
Quick Setup—Configure Role 1 and Role 2
After finishing the device protocol selection, Role 1 and Role 2 of MGate will be confirmed. You will need to
configure the roles on each side by the following steps. Here is an example of Role 1 as a IEC 60870-5-104
server, and Role 2 as a Modbus RTU/ASCII master.

Time Settings
The MGate 5114 has a built-in Real-Time Clock for time calibration functions. Functions such as the log
function can add real-time information to the message.
ATTENTION
First-time users should select the time zone first. The console will display the “real time” according to the
time zone relative to GMT. If you would like to modify the real-time clock, select Local time. MGate’s
firmware will modify the GMT time according to the Time Zone.

Time server
IP or Domain address
(e.g., 192.168.1.1 or
time.stdtime.gov.tw)
This optional field specifies your time server’s IP address or
