MOXA MGate MB3170 Series Modbus TCP Gateway Installation Guide

MOXA MGate MB3170 Series Modbus TCP Gateway

Overview

The MGate MB3170 and MB3270 are 1 and 2-port advanced Modbus gateways that convert between Modbus TCP and Modbus ASCII/RTU protocols. They can be used to allow Ethernet masters to control serial slaves, or to allow serial masters to control Ethernet slaves. Up to 32 TCP masters and slaves can be connected simultaneously. The MGate MB3170 and MB3270 can connect up to 31 or 62 Modbus RTU/ASCII slaves, respectively.

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. 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.

Note: When connecting a single-mode fiber transceiver, we recommend using an attenuator to prevent damage caused by excessive optical power.

Note: Compute the “typical distance” of a specific fiber transceiver as

follows: Link budget (dB) > dispersion penalty (dB) + total link loss (dB).
