MGate MB3660 Series
Quick Installation Guide ****
Overview
The MGate MB3660 (MB3660-8 and MB3660-16) series gateways are 8 and 16-port redundant Modbus gateways that convert between the Modbus TCP and Modbus RTU/ASCII protocols. The gateways come with built-in dual AC or DC power inputs for power redundancy and have dual Ethernet ports (with different IPs) for network redundancy.
The MGate MB3660 series gateways provide not only serial-to-Ethernet communication, but also serial (Master)-to serial (Slave) communication, and can be accessed by up to 256 TCP master/client devices, or connected to 128 TCP slave/server devices.
Each serial port can be configured individually for Modbus RTU or Modbus ASCII operation and for different baud rates, allowing both types of networks to be integrated with Modbus TCP through one Modbus gateway.

Hardware Introduction
As shown in the following figures, the MGate MB3660-8 has 8 DB9/RJ45 ports for transmitting serial data, and the MGate MB3660-16 has 16 DB9/RJ45 ports for transmitting serial data. The MGate MB3660I series gateways provide 2 kV serial port isolation protection.

Reset Button— Press the Reset button continuously for 5 sec to load factory
defaults
The reset button is used to load factory defaults. Hold the reset button down
for five seconds using a pointed object such as a straightened paper clip.
Release the reset button when the Ready LED stops blinking.
LED Indicators
| Name | Color | Function |
|---|
PWR 1,
PWR 2| Red| Power is being supplied to the power input
Off| The power cable is not connected
Ready| Red| Steady on: Power is on and the unit is booting up
Blinking: IP conflict, DHCP, or BOOTP server did not
respond properly, or a relay output occurred
Green| Steady on: Power is on and the unit is functioning normally
Blinking: The unit is responding to the locate function
Off| Power is off, or power error condition exists
Tx| Green| The serial port is transmitting data
Rx| Amber| The serial port is receiving data
LAN 1,
LAN 2| Green| Indicates 100 Mbps Ethernet connection
Amber| Indicates 10 Mbps Ethernet connection
Off| Ethernet cable is disconnected
Hardware Installation Procedure
STEP 1 : After unpacking the unit, use an Ethernet cable to connect the
unit to the network.
STEP 2: Connect your device to the desired port on the unit.
STEP 3: Place or mount the unit. The unit may be placed on a horizontal
surface such as a desktop or mounted on the wall.
STEP 4: Connect the power supply to the unit.
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 5.0 to 7.0 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.
Termination Resistor and Adjustable Pull High/Low Resistors
In some critical environments, you may need to add termination resistors to
prevent the reflection of serial signals. When using termination resistors, it
is important to set the pull high/low resistors correctly so that the
electrical signal is not corrupted. The MGate MB3660 uses DIP switches to set
the pull high/low resistor values for each serial port. To expose the DIP
switches located on the back of the PCB, first, remove the screws holding the
DIP switch cover in place, and then remove the cover. The sequence from right
to left is port 1 to port 16.
To add a 120 Ω termination resistor, set switch 3 on the port’s assigned
DIP switch to ON; set switch 3 to OFF (the default setting) to disable the
termination resistor.
To set the pull high/low resistors to 150 KΩ, s et switches 1 and 2 on
the port’s assigned DIP switch to OFF. This is the default setting. To set the
pull high/low resistors to 1 KΩ, set switches 1 and 2 on the port’s assigned
DIP switch to ON.
Pull High/low Resistors for the RS-485 port
Default
| SW | 1 | 2 | 3 |
|---|---|---|---|
| Pull High | Pull Low | Terminator | |
| ON | 1 K0 | 1 KS) | 1200 |
| OFF | 150 K0 | 150 K0 | – |
