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:

Use a standard straight

-through Ethernet cable to

connect the MGate

Adjustable Pull H igh/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 resistor s 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.
