MGate MB3660 Series

Quick Installation Guide

First Edition, August 2015

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 dual Ethernet ports can use the same IP

address for cable 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

ports for transmitting serial data, and the MGate MB3660-16 has

16 DB9 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, th

e 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

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. The MGate

supports two types of accounts: admin and user. The admin

account can modify all settings, whereas the user account can

only view settings. The default password for the admin account is

“moxa”.

If you forget the modified IP address of the gateway or cannot log

in to the gateway via a web browser for any reason, you can access

the gateway via a direct Ethernet cable connection using the

Device search utility to search for the gateway.

To install Device Search Utility (DSU), insert the MGate

Documentation and Software CD into your PC’s CD-ROM drive,

and then run the following setup program to begin the installation

process from the “Software” directory:

dsu_setup_[Version]_Build_[DateTime].exe

The filename of the latest version may have the following format:

dsu_setup_Verx.x.x_Build_xxxxxxxx.exe.

For detailed information about DSU, refer to the MGate MB3660

User's Manual, which can be found in the “Document” directory.
