microSD
The MGate 5105-MG-EIP 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, GSD files, 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 MGate Manager or 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 MGate to 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 damage.
The MGate will stop for 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otherwise, the out-of-date configuration will copy to the MGate device.

MGate 5105-MB-EIP Introduction
1-9
Configuration Methods
MGate 5105-MB-EIP provides three ways to configure an MGate.
1. MGate Manager (Windows utility)
Use MGate Manager to configure the MGate through Ethernet, or check the MGate status. Refer to Chapter
3for details.
2. Web console
Use the web console to configure the MGate, or verify the MGate’s status, by Ethernet. Use a web browser
such as Microsoft Internet Explorer or Google Chrome to connect to the MGate, using HTTP/HTTPS protocol.
In this case, the MGate IP address must be configured correctly. Refer to Chapter 4 for details.
3. Serial console
Use the serial console to configure the MGate, or verify the MGate’s status, through an RS-232 null modem
(crossover) cable. Use a serial terminal emulation tool such as Moxa PComm Terminal Emulator or PuTTY to
log in to the MGate serial console. Note that the serial console doesn’t provide the interface for all
parameters. Some parameters must be configured through MGate Manager or the web console. You must
use a DP9-to-RJ45 cable to connect the serial console port on the MGate gateway’s front panel to the serial
port on the host. The serial console parameters are 115.2 kbps; parity: none; 8 data bits; and one stop bit.

This chapter provides a quick overview of how to configure the MGate 5105-MB-EIP by web console. For more

Cable Connection
The MGate gateway supports Modbus RTU/ASCII, Modbus TCP, and EtherNet/IP protocol. If the MGate gateway
needs to communicate with Modbus RTU/ASCII devices, connect your Modbus device to the MGate gateway’s
Modbus port. Regardless, at least one of your devices should be Modbus TCP or EtherNet/IP interface. Connect
your Modbus TCP or EtherNet/IP device to the MGate gateway’s 10/100M Ethernet port as well. The MGate
gateway will indicate a valid Ethernet connection in the following ways:
•The Ethernet LED will maintain a solid green color when connected to a 100 Mbps Ethernet network.
•The Ethernet LED will maintain 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
The gateway can be powered by connecting a power source to the terminal block by following the steps below:
1. Loosen or remove the screws on the terminal block.
2. Connect the 12–48 VDC power line to the terminal block. Confirm that the power source is off already.
3. Tighten the connections using the screws on the terminal block.
4. Turn on the power source.
NOTE
Note that the gateway
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
.
Log in to the Web Console
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 the gateway
and host PC are connected through the same Ethernet switch, make sure that there is no router between them.
Then use MGate Manager to detect the MGate gateways on your network. When the MGate gateway appears on
the MGate Manager device list, right-click on the selected MGate and configures it by web console.
On the first page of the web console, enter the admin for the default Account name and moxa for the default
Password.

MGate 5105-MB-EIP Quick Configuration Guide
2-3
Network Settings
First, configure the IP address and Netmask. Contact your network administrator for the appropriate IP
settings information.
Serial Settings
Second, refer to the datasheet of your Modbus RTU/ASCII devices to configure Serial parameters for Modbus
RTU/ASCII devices.

MGate 5105-MB-EIP Quick Configuration Guide
2-4
Protocol Conversion
The MGate 5105-MB-EIP supports Modbus RTU/ASCII, Modbus TCP, and EtherNet/IP protocols, but only one
combination of two different protocols can be selected at a time.
Option Combination
Option 1
EtherNet/IP <-> Modbus RTU/ASCII
Option 2 EtherNet/IP <-> Modbus TCP
Option 3 Modbus RTU/ASCII <-> Modbus TCP
EtherNet/IP Configuration
If you select EtherNet/IP Scanner as your device, MGate 5105-MB-EIP will be configured as Ethernet/IP
Adapter. In Adapter mode, you can choose Automatic configuration to automatically map OT (Originator to
Target) and TO (Target to Originator) data sizes to Modbus data.

MGate 5105-MB-EIP Quick Configuration Guide
2-5
In Scanner mode, you must designate the parameters for each connection. Refer to your EtherNet/IP adapter’s
datasheet to fill out OT and TO parameters.
NOTE
A
PLC may use Output and Input instead of OT and TO.
Modbus RTU/ASCII Network
As with EtherNet/IP setup, you should start by checking if you already have configured the serial parameters
on Serial Settings page.

MGate 5105-MB-EIP Quick Configuration Guide
2-6
In RTU/ASCII Slave mode, the MGate gateway works as a Modbus slave device and waits for the incoming
query from the Modbus master device. You only need to identify the Modbus Slave ID when in Slave mode
In RTU/ASCII Master mode, the MGate works as a Modbus master device and will send the Modbus request to
the Modbus network actively.
Refer to your Modbus device’s datasheet to add Modbus commands.

MGate 5105-MB-EIP Quick Configuration Guide
2-7
Modbus TCP Configuration
The MGate gateway also supports both Modbus TCP Master (i.e. Client) and Slave (i.e. Server) modes. In Slave
mode, assign the Slave ID and confirm that the Modbus device on the remote side can send commands via the
corresponding TCP port.
For Master mode, refer to your Modbus TCP device’s datasheet to specify the command one by one manually.

MGate 5105-MB-EIP Quick Configuration Guide
2-8
I/O Data Mapping
The MGate provides an internal memory for data exchange between Modbus and EtherNet/IP protocols. After
finishing the protocol settings, go to the I/O Data Mapping page and check if the data mapping is connected. In
some cases, you may need to switch to manual arrangement to adjust the internal address for each command.
Communication Analysis
After finishing all configurations, use Communication Analysis to confirm that the settings are correct. Click
Start and wait 10 seconds for the analysis report to appear and describe fail status details, warnings, and hints.
