Can this gateway be used in hazardous locations?

Yes, the MGate MB3170I-T is certified for ATEX Zone 2, IECEx, and UL/cUL Class 1 Div 2 hazardous locations. It must be installed in an enclosure with at least IP54 protection.

What serial protocols are supported?

The gateway supports Modbus RTU, Modbus ASCII, and Modbus TCP protocols. It converts between Modbus TCP and Modbus serial (RTU/ASCII).

How many Modbus slaves can be connected?

Up to 31 Modbus RTU/ASCII slaves can be connected via the serial port. Up to 32 Modbus TCP masters/slaves can be connected simultaneously.

What is the operating temperature range?

The -T model operates from -40°C to 75°C (-40°F to 167°F). Standard models operate from 0°C to 60°C.

How do I configure the MGate MB3170I-T?

Configuration can be done via a web browser (default IP above) or using MGate Manager or Device Search Utility (DSU) downloaded from Moxa's website.

What power supply is required?

The gateway requires a 12 to 48 VDC power source. Power consumption is 555 mA max. Connect to the terminal block power input (V1+/V1- and V2+/V2- for dual inputs).

What do the LED indicators mean?

PWR1/PWR2 (red): power on. RDY (green): normal operation; (red): booting/error. Ethernet (amber:10M, green:100M). P1/P2 (amber:rx, green:tx). FX (amber): fiber connection.

Is the MGate MB3170I-T repairable?

Moxa devices are designed for reliability. For repairs, contact Moxa technical support or an authorized service center. The device has no user-serviceable parts inside.

PWR2	Red	Power is being supplied to the power input
RDY	Red	Steady: 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: Power is on and the unit is functioning normally
		Blinking: Unit is responding to locate function
	Off	Power is off or power error condition exists

Reset Button

Press the Reset button continuously for 5 sec to load factory defaults:

The reset button is used to load factory defaults. Use a pointed object such as a straightened paper clip to hold the reset button down for five seconds. Release the reset button when the Ready LED stops blinking.

Panel Layouts

The MGate MB3170 has a male DB9 port and a terminal block for connecting to serial devices. The MGate MB3270 has two DB9 connectors for connecting to serial devices.

Hardware Installation Procedure

STEP 1: After removing the MGate MB3170/3270 from the box, connect the MGate MB3170/3270 to a network. Use a standard straight-through Ethernet (fiber) cable to connect the unit to a hub or switch. When setting up or testing the MGate MB3170/3270, you might find it convenient to connect directly to your computer's Ethernet port. In this case, use a crossover Ethernet cable.

STEP 2: Connect the serial port(s) of the MGate MB3170/3270 to a serial device.

STEP 3: The MGate MB3170/3270 is designed to be attached to a DIN rail or mounted on a wall. The two sliders on the MGate MB3170/3270 rear panel serve a dual purpose. For wall mounting, both sliders should be extended. For DIN-rail mounting, start with one slider pushed in, and the other slider extended. After attaching the MGate MB3170/3270 on the DIN rail, push the extended slider in to lock the device server to the rail. The two placement options are illustrated in the accompanying figures.

STEP 4: Connect the 12 to 48 VDC power source to terminal block power input.

Wall or Cabinet Mounting

Mounting the MGate MB3170/3270 Series on to a wall requires two screws. The heads of the screws should be 5 to 7 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.

NOTE Wall mounting is certified for use in maritime applications.
