MGate MB3660 Series
Quick Installation Guide
Second Edition, October 2017
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 baudrates, 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.

Hardware Installation Procedure
STEP 1:
After unpacking the unit, connect the power supply to the
unit.
STEP 2:
Use an Ethernet cable to connect the unit to the network.
STEP 3:
Connect your device to the desired port on the unit.
STEP 4:
Place or mount the unit. The unit may be placed on a
horizontal surface such as a desktop, or mounted on 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.
For each screw, the head should be 6.0 mm or
less in diameter, and the shaft should be 3.5 mm
or less in diameter.
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
