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.

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).
