1. Introduction
Welcome to the MGate MB3660 Series of 8 or 16-port Modbus gateways that convert between Modbus TCP
and Modbus RTU/ASCII protocols.
All MB3660 gateways (MB3660-8, MB3660-16) have dual AC/DC power inputs and dual IP addresses built in
for redundancy. Magnetic serial port isolation is also provided for “-I” models.
In this chapter, we give an introduction to the MGate MB3660. The following topics are covered:

MGate MB3660 Modbus Gateway Introduction
1-2
Overview
The MGate MB3660 (MB3660-8 and MB3660-16) Series comprises redundant Modbus gateways that convert
between Modbus TCP and Modbus RTU/ASCII protocols. They can be accessed by up to 256 Modbus TCP
client (master) devices, or connect to 128 Modbus TCP server (slave) devices. The MGate MB3660 isolation
model provides 2 kV isolation protection suitable for power substation applications. The MGate MB3660
gateways are designed to easily integrate Modbus TCP and RTU/ASCII networks. The MGate MB3660
gateways offer features that make network integration easy, customizable, and compatible with almost any
Modbus network.
For large-scale Modbus deployments, MGate MB3660 gateways can effectively connect a large number of
Modbus nodes to the same network. The MB3660 Series can physically manage up to 248 serial slave nodes
for 8-port models or 496 serial slave nodes for 16-port models (the Modbus standard only defines Modbus
IDs from 1 to 247). Each RS-232/422/485 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.
High Performance with Innovative Command Learning
The MGate MB3660 gateways support two communication modes: transparent mode and agent mode. For
transparent mode, the gateway converts Modbus commands from Modbus TCP to Modbus RTU/ASCII, and
vice versa, or from serial Master to serial Slave. However, since only one Modbus protocol request-response
action can be executed at any given time, each Modbus device has to wait its turn, resulting in poorer
performance. Agent mode is designed to overcome this performance weakness. By allowing users to
manually key in Modbus commands, the gateway can send Modbus commands to multiple Modbus devices
at the same time. Since the gateway actively and continuously retrieves data from Modbus devices
simultaneously through the different serial ports, users will see a dramatic reduction in the amount of time a
Modbus device needs to wait to be accessed. SCADA systems can retrieve Modbus device data directly from
the gateway’s memory, instead of waiting for the gateway to pass commands to the serial ports, enhancing
the Modbus gateway’s communication performance.
Transparent mode helps users adopt existing SCADA programs, but with reduced communication
performance, whereas agent mode is characterized by high performance, but it requires users to go through
the trouble of keying in Modbus commands. In order to provide better performance, without requiring users
to key in a lot of Modbus commands, the MGate MB3660 gateways are designed with an innovative
Command Learning function, which can be activated with a single mouse click. Once activated, the gateway
will learn and memorize the Modbus commands it receives, and once a command has been learned, the
gateway will act as though it were in agent mode and actively send Modbus requests to the relevant Modbus
devices. Since the data is saved in a different memory space that can be accessed by the SCADA system,
the SCADA system can retrieve Modbus response data directly from the gateway’s memory, instead of
waiting for the data to pass through the Modbus devices, dramatically increasing communication
performance.
Windows-Based Utility and Web Console for Easy Setup
A Windows-based utility (refer to Chapter 3) is provided to make it easy to search for and locate devices,
assign IP addresses, import/export configuration files, and upgrade the the MGate MB3660’s firmware. The
utility automatically connects to all available MGate MB3660 units on the LAN. A user-friendly web console
(refer to Chapter 4) is provided to configure the device from a web browser.

Connecting the Power
The unit can be powered by connecting a power source to the terminal block for DC models or power
connector for AC models.
For DC power input models:
1. Loosen or remove the screws on the terminal block.
2. Connect the 20-60 VDC power line to the terminal block.
3. Tighten the connections using the screws on the terminal block.
For AC power input models:
• Connect the 100-240 VAC power line to the AC connector.
Note that the unit does not have an on/off switch. It automatically turns on when it receives power. The
PWR LED on the front panel will glow to indicate that the unit is receiving power. There are two DC power
inputs for redundancy.
Connecting Serial Devices
The unit’s serial port(s) are located on the back panel. If you are connecting an RS-485 multidrop network
with multiple devices, note the following:
• All devices that are connected to a single serial port must use the same protocol (i.e., either Modbus
RTU or Modbus ASCII).
• Each master device must connect to its own port on the unit. If you are connecting to a network with
both master and slave devices, the master must be connected to a separate port from the slaves.
For serial port pin assignments, refer to the Pin Assignments section.
Connecting to a Host or the Network
Two 10/100BaseT Ethernet ports are located on the gateway’s back panel. These ports are used to connect
the unit to a host or Ethernet network, as follows:
• For normal operation, use a standard straight-through Ethernet cable to connect the unit to your Modbus
TCP network.
• For initial configuration or for troubleshooting purposes, you may connect the unit directly to a PC.
The unit’s Link LED will light up to indicate a live Ethernet connection.
The MGate MB3660 has two Ethernet ports with two MAC addresses. Hence, the unit can be connected by
two different IP addresses.

Wiring Requirements
You should also observe the following common wiring rules:
• Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the point of intersection.
• You can use the type of signal transmitted through a wire to determine which wires should be kept
separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled
together.
• Keep input wiring and output wiring separate.
• When necessary, we strongly advise labeling wiring to all devices in the system.

Adjustable Pull High/Low Resistors for the RS485 Port
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. Tear open the screws and find the DIP switches located at the back side of the
PCB.
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.

Pin Assignments
The MGate MB3660 uses DB9 serial ports to connect to Modbus RTU or ASCII devices. Each port supports
three serial interfaces that select by software: RS-232, RS-422, and RS-485 (both 2 and 4-wire).

Starting Device Search Utility (DSU)
DSU is a Windows-based utility that is used to configure the MGate MB3660 Series.
Before running DSU, make sure that your PC and the MGate MB3660 are connected to the same network.
Alternatively, the MGate MB3660 Series may be connected directly to the PC for configuration purposes.
Refer to Chapter 2 for more details.
You may open DSU from the Windows Start menu by clicking Start Programs MOXA DSU. The
DSU window should appear as shown below.
Connecting to the Unit
The DSU needs to connect to the unit before the unit can be configured. There are two methods to connect
to the unit. Broadcast Search is used to find all MGate MB3660 units on the LAN. Search IP attempts to
connect to a specific unit by IP address, which is useful if the unit is located outside the LAN or can only be
accessed by going through a router.
