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.

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.

power.

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

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