Overview
The MGate MB3180 is a 1-port Modbus gateway that converts between
Modbus TCP and Modbus ASCII/RTU protocols. It can be used to allow
Ethernet masters to control serial slaves, or to allow serial masters to
control Ethernet slaves. Up to 16 TCP masters and 31 serial slaves can
be connected simultaneously.

Notify your sales representative if any of the above items is missing or
damaged.
NOTE
The operating temperature of the power adapter in the box is
from 0 to 40
°C. If your application is out of this range, please
use a power adapter supplied by UL Listed External Power
Supply (The power output meets SELV and LPS and
is rated 12
-
48 VDC; minimum current is 0.73 A). Moxa has power
adapters with wide temperature range (
-40 to 75 °C, -
40 to 167
F), the PWR-12150-(plug type)-SA-T series, for your reference.

Hardware Introduction
As shown in the following figures, the MGate MB3180 has one DB9 male
port for transmitting serial data.
Reset Button—The reset button is used to load factory defaults. Using
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 in order to load the factory defaults.

Hardware Installation Procedure
STEP 1:
After unpacking the MGate MB3180, connect the power
adaptor
.
STEP 2:

MGate
MB3180 to a network hub or switch. Use a cross-over
Ethernet cable if you are connecting the gateway directly to a
PC
.
STEP 3:
Connect your device to the MGate MB3180
’s serial port.
STEP 4:

on a horizonta
l serface such as a desktop, mounted on a DIN
-
rail, or mounted on the wall.

Adjustable Pull High/Low Resistors for the RS-485 Port
In some critical RS-485 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. Jumpers
JP3 and JP4 are used to set the pull high/low resistor values for the
serial port. To Set the pull high/low resistors to 150 KΩ, which is the
factory default setting, leave the two jumpers open. To set the pull
high/low resistors to 1 KΩ, use the jumper caps to short the two
jumpers.
