1. Introduction
The MGate 5121 is an industrial Ethernet gateway for converting CANopen or J1939 to Modbus TCP and
SNMP network communications. To integrate existing CANopen or J1939 devices into a Modbus TCP or
SNMP network, use the MGate 5121 as a CANopen or J1939 master to collect data and exchange data with
the Modbus TCP host or SNMP client. All models are protected by a rugged and compact metal housing and
are DIN-rail mountable. The rugged design is suitable for industrial applications such as factory automation
and other process automation industries.

2. 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 that 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 show that the unit is receiving power. For power terminal block pin
assignments, refer to the Quick Installation Guide, Power Input and Relay Output Pinout section.
Connecting CAN Devices
The MGate supports CAN devices. Before connecting or removing the serial connection, first make sure the
power is turned off. For the CAN port pin assignments, refer to the Quick Installation Guide, Pin
Assignments section.
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 show 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 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. The Welcome window will greet you. 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 copy the software files.
6. A progress bar will appear. The procedure should take only a few seconds to complete.
7. A message will show the DSU has been 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 Google Chrome to connect to the MGate, using the 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 login page, create an account name and set a password when you log in for the first time. Or if you
have already an account, log in with your account name and password.
microSD
The MGate provides users with an easy way to back up, copy, replace, or deploy. The MGate is equipped
with a microSD card slot. Users can plug in a microSD card to back up data, including the system
configuration settings.
First time use of a new microSD card with the MGate gateway
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 use of a microSD card containing a configuration file with the
MGate gateway
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.

MGate 5121 Series User Manual
7
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 into 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 256 Mbytes of free space remaining.
2. The microSD card is write-protected.
3. The file system is corrupted.
4. The microSD card is damaged.
In case of the above events, the MGate will flash Ready LED in red color. 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 be copied to the MGate device.

Time Settings
The MGate has a built-in real-time clock for time-calibration functions. Functions such as logs use the real-
time clock to add the timestamp to messages.
ATTENTION
First-time users should select the time zone first. The console will display the actual time in your time zone
relative to the GMT. If you would like to change the real-time clock, select Local time. MGate’s firmware
will change the GMT time according to the Time Zone setting.
