Wall Mount
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).
Hardware Installation Procedure
1. Connect the power adapter. Connect the 12-48 VDC power line or
DIN-rail power supply to the MGate 5121’s terminal block.
2. Use a CAN cable to connect the MGate to the CAN device.
3. Use an Ethernet cable to connect the MGate to the Modbus TCP
client.
4. The MGate 5121 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-mounting kit (optional) first and then
screw the device onto the wall.
When wiring the relay contact (R) 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 stripping length is
recommended to be 8 to 9 mm. The wire temperature rating should be
at least 85°C. Use copper conductors only. The shielding ground screw
(M4) is near the power connector. When you connect the shielded
ground wire (min. 16 AWG), the noise is routed from the metal chassis
to the ground.

The following figure illustrates the two mounting options:
Wall- or Cabinet-mounting
We provide two metal plates to mount 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 the
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
over 10.5 mm.
Software Installation Information
Please download the User Manual and Device Search Utility (DSU) from
Moxa’s website: www.moxa.com
For using the DSU, refer to the User’s Manual. The MGate 5121 also
supports login via a web browser.
