NPort S8000 Series Software Installation/Configuration
7-9
1. On the Basic Setting window, use the COM Number drop-down list to select a COM number to be
assigned to the NPort S8000’s serial port that is being configured. Select the Auto Enumerating COM
Number for Selected Ports option to automatically assign available COM numbers in sequence to
selected serial ports. Note that ports that are “in use” will be labeled accordingly.
2. Click the Advanced Settings tab to modify Tx Mode, FIFO, and Flash Flush.
Tx Mode
Hi-Performance is the default for Tx mode. After the driver sends data to the NPort S8000, the driver
immediately issues a “Tx Empty” response to the program. Under Classical mode, the driver will not send the
“Tx Empty” response until after confirmation is received from the NPort S8000’s serial port. This causes lower
throughput. Classical mode is recommended if you want to ensure that all data is sent out before further
processing.
