Configuring the Ports
After the board and serial port drivers are installed, the board’s Properties window will appear. The system will
map the ports automatically. You may be prompted to take care of port configuration if other Moxa boards have
been installed.

On the Ports Configuration tab, select a port to configure and click Port Setting.

Under Port Number, select a COM number to assign to the serial port. Select Auto Enumerating COM
Number to map subsequent ports in numerical order. For example, if COM 3 is assigned to Port 1, then
COM 4 will be automatically assigned to Port 2.

Select an Rx FIFO Trigger and Tx FIFO Size. The default Rx FIFO Trigger is 120 bytes (high level). The
default Tx FIFO Size is 128 bytes (high level). Select Set the change to all ports to use this setting for all
