Off
No serial communication with Modbus device
Green
Normal Modbus serial communication in
progress
Red
An error in serial communication occurred
When the MGate 5109 acts as a Modbus
master:
1. The slave device returned an error
(exception)
2. Received a framing error (parity error,
checksum error)
3. Timeout (the slave device sends no
response)
When the MGate 5109 acts as a Modbus slave:
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)
DNP3*
Off
No serial communication with a DNP3 device
Green
Normal DNP3 serial communication in progress
Red
An error in serial communication occurred
When the MGate 5109 acts as a DNP3 master:
1. Received an outstation exception (format
error, checksum error, invalid data,
outstation responds are not supported)
2. Timeout (the outstation sends no
response)
When the MGate 5109 acts as a DNP3
outstation:
1. Received a master exception (format
error, checksum error, invalid data)
2. Timeout (the master sends no response)
*Only indicates serial communication status; for Ethernet status, please
refer to the LED indicator on the Ethernet port.

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 5109’s top cover, you will find DIP switches to
adjust each serial port’s pull-high resistor, pull-low resistor, and
terminator.

Hardware Installation Procedure
1. Connect the power adapter. Connect the 12-48 VDC power line or
DIN-rail power supply to the MGate 5109’s terminal block.
2. Use a serial cable to connect the MGate to the Modbus or DNP3
device.
3. Use an Ethernet cable to connect the MGate to the Modbus or DNP3
device.
4. The MGate 5109 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.
The following figure illustrates the two mounting options:
