Pull-up, Pull-down, and Terminator for RS-485
For serial port 1, on the MGate’s left side panel, you will find DIP switches to adjust each serial port’s pull-up resistor, pull-down resistor, and terminator. For serial port 2, you may need to open the case, and find the DIP switch on the PCB as in the following figure.

Hardware Installation Procedure
- Connect the power adapter. Connect the 12-48 VDC power line or DIN-rail power supply to the MGate terminal block. Make sure the adapter is connected to an earthed socket.
- Use an EtherCAT cable to connect the MGate to an EtherCAT PLC or other EtherCAT master.
- Use a serial cable to connect the MGate to the Modbus or other serial devices.
- The MGate is designed for standalone installation and 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:
Software Installation Information
Please download the user’s manual and Device Search Utility (DSU) from Moxa’s website: www.moxa.com. Please refer to the User’s Manual for additional details on using the DSU.
- The MGate 5216 also supports login via a web browser.

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).

Conditions of Safe Use
- The manufacturers intend Ethernet communications devices to be mounted in a tool-accessible IP54 enclosure and used in an area with no more than pollution degree 2, as defined by IEC/EN 60664-1.
- Conductors suitable for an ambient temperature greater than 85°C must be used for the power supply terminal.
- When using a connection to the external grounding screw, you must use a 4 mm2 conductor.
- To prevent the rated voltage from exceeding 140% of the peakrated voltage during transient disturbances, provisions should be made either in the equipment or external to it.
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. We recommend a stripping length of 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. Through the shielding ground screw (M4), the noise is directly routed from the metal chassis to the ground.
- ATTENTION
- Power terminal plug wiring size is 28-14 AWG, tighten to 1.7 in-lbs, wire min. 80°C. Use copper conductors only.
- WARNING
- Hot Surface
- External metal parts of this equipment are extremely hot. Before touching the equipment, you must take special precautions to protect your hands and body from serious injury.
