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.

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, set 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.

Software Installation Information
To configure your MGate MB3660, connect the gateway’s Ethernet port
directly to your computer’s Ethernet port and then log in from a web
browser. The default IP addresses of LAN1 and LAN2 are
192.168.127.254 and 192.168.126.254, respectively.
You can download the User's Manual and Device Search Utility (DSU)
from Moxa's website: www.moxa.com
