Connecting 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. Connect the 12–48 VDC power line to the terminal block. Please confirm the power source is off already.
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 indicate that the unit is receiving power. For power terminal block pin
assignments, please refer to chapter 2 Power Input and Relay Output Pinout section.
Connecting PROFIBUS Devices
The unit’s PROFIBUS port(s) are located on the front panel. Use a PROFIBUS cable to directly connect the unit
to the PROFIBUS devices or PROFIBUS network. Before connecting or removing the RROFIBUS connection,
please confirm the power is turned off first.
For the PROFIBUS port pin assignments, please refer to chapter 2 Pin Assignments section. This information
can then be used to construct users own PROFIBUS cable.
Connecting to Network
Connect one end of the Ethernet cable to MGate’s 10/100M Ethernet port and the other end of the cable to the
Ethernet network. 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
First Time MGate Configuration
To configure MGate 5101-PBM-MN properly, there are several basic configurations that users have to do first.
User can get a quick overview to make the MGate work properly from the following section. For detail
information of each configuration items, please refer the chapter 4 Configuration.
MGate Manager Utility
The best way to configure the MGate 5101-PBM-MN is to use MGate Manager. In most cases, users may not
know the IP address setting when they get the MGate. For this situation users can use Ethernet cable to connect
the host and MGate directly. (Or in the same Ethernet switch. Just make sure there is no router between them)
MGate Manager can detect the MGate for users properly. If you want to use web or telnet/SSH console, you
have to configure MGate with proper IP address first. It will not be so convenient.
When you can see the MGate is in the MGate Manager devices list, now you can configure it for all options.

MGate 5101-PBM-MN UM Getting Started
3-3
Network Settings
The first thing to configure MGate is the network settings for communication. You must to configure the IP
address and netmask properly. If you don’t know how to configure it, you can contact the IT department for
detail configuration. Please refer to chapter 4 Network Settings section.
Data Transfer
The second thing is to configure the PROFIBUS and Modubs protocol. MGate provides the internal memory for
data transfer between PROFIBUS and Modbus. Both sides will transfer the data between the interface and this
internal memory, so users have to understand the structure of this internal memory first. Please refer to the
chapter 4 Data Exchange Between Modbus TCP and PROFIBUS section. Users have to plan how many
data they want to transfer between PROFIBUS and Modbus devices first.
PROFIBUS Network
In PROFIBUS interface, MGate works as the PROFIBUS master. So you have to configure the PROFIBUS
network first. Before connecting the slave devices to MGate, users need to configure all slave devices properly
such as address and I/O modules. To configure the PROFIBUS slaves for MGate, users can use the AutoScan
function in MGate Manager PROFIBUS settings to get all settings of devices which is present on the PROFIBUS
network automatically. Please refer to the chapter 4 PROFIBUS Settings section. Users also can add the I/O
module for each salve devices, and configure the proper internal memory settings manually.
To confirm the PROFIBUS slave devices work properly, users can check the LED in the front panel of MGate. If
succeed, the “PBM” LED will show steady green light. To check the I/O module data is exchanged correctly,
users can use web console I/O Data View to check MGate internal memory. The data which is used by
PROFIBUS and Modbus TCP will be displayed for verification.
If any slave devices may not work properly, users will see the “PBM” LED is flashing. Users can use MGate
Manager Diagnoseto check which slave causes the problem. The Log Settings function is also another good
way to check the communication issue. If any PROFIBUS connection lost, it will record the event into system
flash memory for future verification.
Modbus TCP Configuration
In Modbus TCP interface, MGate supports master and slave configurations. Slave mode will be easier to
configure. Users need to confirm the Modbus master in remote side can send the command properly. For
master mode, users have to specify the command one-by-one manually. Again, users also have to understand
the internal memory configuration properly. Please refer to the chapter 4 Modbus Settings section.
To check the I/O module data is exchanged correctly, users can use web console I/O Data View to check
MGate internal memory. Users can use MGate Manager Diagnoseto check if any Modbus TCP communication
issue happened. The invalid response or timeout issue will be displayed in the diagnose window. To confirm the
Modbus TCP connections work well, users can use web console to show all the connections information. The
Log Settings function is also another good way to check the communication issue.
Configure the MGate
MGate 5101-PBM-MN provides four ways to configure the MGate.
1. MGate Manager (Windows utility)
Use MGate Manager to configure the MGate through Ethernet or check the MGate status. Please refer to
chapter 4 Configuration for detail information.

MGate 5101-PBM-MN UM Getting Started

2. Web console
Use Web console to configure the MGate through Ethernet or verify the MGate status. User can use web
browser such as Microsoft Internet Explorer or Google Chrome to connect to MGate with HTTP/HTTPS
protocol. In this case the MGate IP address must be configured correctly. Note Web console doesn’t provide
the interface for all parameters. Some parameters must be configured through MGate Manager. Please
refer to chapter 5 Configuration for detail information.
3. Text mode console
Use Telnet/SSH console to configure the MGate through Ethernet or verify the MGate status. Users can use
the Telnet tool such as HyperTerminal or PuTTY to login to MGate with Telnet or SSH protocol. In this case
the MGate IP address must be configured correctly. Note Telnet/SSH doesn’t provide the interface for all
parameters. Some parameters must be configured through MGate Manager. Please refer to chapter 6
Configuration for detail information.
4. Serial console
Use serial console to configure the MGate through RS232 null modem (crossover) cable or verify the MGate
status. The interface will be same as Telnet console. Users can use the serial terminal emulation tool such
as Moxa PComm Terminal Emulator or PuTTY to login to MGate serial console. Note serial console doesn’t
provide the interface for all parameters. Some parameters must be configured through MGate Manager.
The RS-232 serial console port is located on the unit’s front panel. Please refer to chapter 6 Configuration
for detail information.

Change Language Setting
If you want to run MGate Manager in a different language, you may click Language to change the language
setting. A dialog box showing the available languages should appear as shown below.
When you click OK, MGate Manager will immediately reflect your chosen language.
After changing to a different language, you will find that all strings on MGate Manager are replaced in your
chosen language. For example, the above picture is shown in traditional Chinese. Note that no matter what
language you choose, it won’t change the label on the language button.
ATTENTION
Set your MGate Manager to “Default Language” before contacting Moxa Technical Support.
With support for multiple languages, MGate Manager is more user-friendly and accessible. However, if you
need assistance from Moxa Technical Support, please change the language to “Default Language”. This will
prevent any misunderstandings or confusion about MGate Manager menu items and commands as our
engineers assist you.
The default language is En
glish and will only be active for the current MGate Manager session. When you open
MGate Manager again, the language will revert to your original setting.
