MGate MB3000 Modbus Gateway Getting Started
Connecting to a Host or the Network
A 10/100BaseT Ethernet port is located on the unit’s front panel. This port is used for the unit’s connection to a host or Ethernet network, as follows:
• For normal operation, use a standard straight-through Ethernet cable to connect the unit to your Modbus
TCP network.
• For initial configuration or for troubleshooting purposes, you may connect the unit directly to a PC. In this case, use a crossover Ethernet cable to connect the unit to your PC’s Ethernet connector.
The unit’s Link LED will light up to indicate a live Ethernet connection.
For advanced models (MB 3170, MB3170I, MB3270, and MB3270I), two Ethernet ports are provided. One port can be used to connect to the network, and the other port can be used to connect to another Ethernet device.
Installing the Software
The Windows management utility is installed from the Document and Software CD. Follow the onscreen instructions after inserting the CD. For additional details, please refer to Chapter 9.
Mounting the Unit
The unit can be placed on a desktop, mounted on the wall, or mounted on a DIN-rail. The MB3180, MB3280, and MB3480 require optional attachments for DIN-rail mounting. For additional details, please refer to the hardware reference chapter for your model.

Jumpers
Hardware: MB3180
To set the pull high/low resistors to 150 KΩ, leave jumpers JP3 and JP4 open (not shorted). This is the default setting.
To set the pull high/low resistors to 1 KΩ, short jumpers JP3 and JP4 with jumper caps.
ATTENTION
Do not use the 1 KΩ pull high/low setting on the MGate MB3000 when using the RS-232 interface. Doing so will degrade the RS-232 signals and reduce the effective communication distance.
