Reset Button
Restore the MGate to factory default settings by using a pointed object
(such as a straightened paper clip) to hold the reset button down until
the Ready LED stops blinking (approximately five seconds).
Pull-Up, Pull-Down, and Terminator for RS-485
(Modbus)
On the MGate 5111’s left side panel, you will find DIP
switches to adjust each serial port’s pull

Rotary Switch
Before communicating, you must assign a slave ID to
the PROFIBUS slave, If you would like to assign an
address between 0 to 99, you need to change the
rotary switch to the desired address. If you would like
to assign an address which is over 99, you must set it
via web console.
Hardware Installation Procedure
1. Connect the power adapter. Connect the 12-48 VDC power line or
DIN-rail power supply to the MGate 5111’s terminal block. Make
sure the adapter is connected to an earthed socket.
2. Use a PROFIBUS cable to connect the MGate to a PROFIBUS PLC or
other PROFIBUS master.
3. Use an Ethernet cable to connect the MGate to the Modbus TCP
client, Modbus TCP server device, PROFINET IO controller, or
EtherNet/IP scanner device.
4. The MGate 5111 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.
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.
The following figure illustrates the two mounting options:

5. The conditions of safe use:
a. Ethernet Communications Devices are intended for mounting in
a tool-accessible IP54 enclosure and use in an area of not more
than pollution degree 2 as defined by IEC/EN 60664-1.
b. Conductors suitable for an ambient temperature greater than
85°C must be used for the power supply terminal.
c. A 4 mm2conductor must be used when a connection to the
external grounding screw is used.
d. Provisions shall be made, either in the equipment or external to
the equipment, to prevent the rated voltage from exceeding the
transient disturbances of by 140% of the peak-rated voltage.
When wiring the relay contact (R), digital input (DI), and power inputs
(P1/P2), we suggest using American Wire Gauge (AWG) 16 to 20 as a
cable and the corresponding pin-type cable terminals. The connector
can withstand a maximum torque of 5 pound-inches. The stripping
length is recommended to be 8 to 9 mm. The wire temperature rating
should be at least 85°C.
The shielding ground screw (M4) is near the power connector. When
you connect the shielded ground wire (min. 16 AWG), the noise is
routed directly from the metal chassis to the ground.
