Quick Installation Guide
Third Edition, June 2008
1. Overview
The MGate MB 3180 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.

order to load the factory defaults.
LED Indicators—Three LED indicators are located on the top panel:
Name Color Function
On: Power is on and the unit is booting
up
Red Blinking: IP conflict exists, or DHCP or
BOOTP server is not responding
properly.
On: Power is on and the unit is
functioning normally
Green Blinking: Unit has been found by the Location
command in MGate Manager.

4. Hardware Installation Procedure
STEP 1: After unpacking the MGate MB 3180, connect the power
adaptor.
STEP 2: Use a standard straight-through Ethernet cable to connect the
MGate MB 3180 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: Place or mount the MGate MB3180. The unit may be placed

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.
