Hardware Introduction

LED Indicators

LED	Color	Description
POWER1 (P1) POWER2 (P2)	Green	Power is on.
Off	Power is off.

READY (R)

| Off| Power is off.

Green

| Steady: Power is on, and the MGate is

functioning normally.

Blinking (1 sec.): The MGate has been located by the Moxa utility DSU Location function.

Red

| Steady: Power is on, and the MGate is

booting up.

Blinking slowly (0.5 sec.): Shows an IP conflict, or the DHCP server is not responding properly.
Blinking quickly (0.1 sec.): The microSD card

failed.

MODBUS (MB)

[as Modbus TCP Server]| Off| No communication
Green| Steady: Normal communication in progress.

Red

| Blinking (1 sec.): Communication error

1. Received an invalid function code

2. Master accessed invalid register address or coil addresses

3. Received frame error (parity error,

checksum error)

CAN

[as CANopen]| ****

Green

| Steady green: In CANopen OPERATIONAL state.
Blinking green: In CANopen PRE- OPERATIONAL state.
Single flash: In CANopen STOP state.
Red| Steady red: CAN bus off
| | Single flash: An error counter warning level has been reached.
---|---|---
Double flash: A heartbeat event has

occurred.

CAN

[as J1939]| Off| No J1939 I/O configured
Green| Steady: CAN bus (J1939) communication is

receiving or transmitting data.

Red

| Steady: A communication error occurred

1. The J1939 address claim failed

2. CAN is in bus-off state because the error counter is exceeding its limitations.

CAN TX/RX| Green| Flashing: CAN bus port is receiving data
Amber| Flashing: CAN bus port is transmitting data

ETH 1, ETH 2

| Green| Steady ON: Ethernet link on at 100Mbps
Blinking: Data transmitting at 100Mbps
Amber| Steady ON: Ethernet link on at 10Mbps
Blinking: Data transmitting at 10Mbps
Off| Link is down or not connected

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

Connect the power adapter. Connect the 12-48 VDC power line or DIN-rail power supply to the MGate 5121’s terminal block.
Use a CAN cable to connect the MGate to the CAN device.
Use an Ethernet cable to connect the MGate to the Modbus TCP client.
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.
