8.Select the just installed CP-168U board from the Board Type pull-down list, click on a specific port item, and then click on the [Port Setting] button to open the Port X window.

9.Select a COM number for the specific port from Port Number pull-down list.

10.Check the Auto Enumerating COM Number check-box to have subsequent ports mapped to continuous COM numbers. For example, if COM3 is assigned to Port 1, then COM4 will be automatically assigned to Port 2.

11.Select an Rx FIFO Trigger from the Rx FIFO Level pull-down list. Rx FIFO trigger levels from High to Low are available, with a default value is High Level (120 bytes). Check Set the change to all ports check-box to apply the just defined Rx FIFO Trigger to all ports.

12.Select a Tx FIFO Size from the Tx FIFO Level pull-down list. Tx FIFO Level from High to Low are available, with a default value is High Level (128 bytes). Check Set the change to all ports check-box to apply the just defined Tx FIFO Size to all ports.
