4.Click on the specific port and click [Port Setting] button to re-assign the desired COM number for the Smartio C168H/PCI port mapping.

Note! Step 5 is optional, if you want to assign COM numbers to Port manually.

5.Check Auto Enumerating COM Name check-box to assign continuous COM numbers for subsequent ports. For example, if COM 3 is assigned to Port 1, then COM 4 will be automatically assigned to Port 2.

Note! Step 6 and 7 are optional, if the system doesn’t require a special performance tuning.

6.Re-assign the Rx FIFO Trigger by selecting a number from the pull-down list. Check Set the change to all ports check-box if desire to apply this setting to all ports.

Rx FIFO trigger levels, at 1, 4, 8 or 14 bytes, are available, and the default value is 14 bytes.

7.Re-assign the Tx FIFO Size by selecting a number from the pull-down list. Check Set the change to all ports check-box if desire to apply this setting to
