Hardware Introduction

LED Indicators

Agent Mode:

functioning normally

Red| Steady: Power is on, and the MGate is booting

up

Blinking slowly: Indicates an IP conflict, or the DHCP or BOOTP server is not responding properly
Flashing quickly: the microSD card failed
MB*| Off| No serial communication with Modbus device
Green| Normal Modbus serial communication in

progress

Red| An error in serial communication occurred When the MGate 5114 acts as a Modbus RTU/ASCII master:

1.    The slave device returned an error (exception)

2.    Received a framing error (parity error, checksum error)

3.    Timeout (the master sends but no

response)

1.    Received an invalid function code

The master accessed an invalid register address or coil address

2.    Received a framing error (parity error,

checksum error)

101*| Off| No serial communication with the IEC

60870-5-101 device

Green| Normal IEC 60870-5-101 serial communication

in progress

Red| An error in serial communication occurred When the MGate 5114 acts as an IEC 60870-5-101 master:

1.    Received a slave exception (format error, checksum error, invalid data, slave responds are not supported)

2.    Timeout (the master sends but no response)

When the MGate 5114 acts as an IEC 60870-5-101 slave:

Received a master exception (format error,

checksum error, invalid data)

Only indicates serial communication status; for IEC 60870-5-104 or
Modbus TCP status, please refer to the LED indicator on the Ethernet port.

Dimensions

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-high, Pull-low, and Terminator for RS-485

Beneath the MGate 5114’s top cover, you will find DIP switches to adjust
each serial port’s pull-high resistor, pull-low resistor, and terminator.

SW

| 1| 2| 3
---|---|---|---
Pull-high resistor| Pull-low resistor| Terminator
ON| 1 kΩ| 1 kΩ| 120 Ω
OFF| 150 kΩ| 150 kΩ| –*

Hardware Installation Procedure

1.  Connect the power adapter. Connect the 12-48 VDC power line or DIN-rail power supply to the MGate 5114’s terminal block.
2.  Use a serial cable to connect the MGate to the Modbus RTU/ASCII or IEC 60870-5-101 device.
3. Use an Ethernet cable to connect the MGate to the Modbus TCP or IEC 60870-5-104 device.
4. The MGate 5114 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.

The following figure illustrates the two mounting options:
