Hi,
On page 18 of the manual you attached specifies the configuration of the serial port on your PC:
9600 bps, 8 Data bits, 1 start bit, 1 stop bit, no parity and no flow control.
This is the information you need to configure the serial port on your PC. The rest of the information on the manual specifies the format of the frames the devices recognizes. This information is specific to your device and determines you would program your application. Basically how the data is packaged.
Your questions is too generic. There are a lot of resources on the web and on NI's web site on serial communication. It mainly depends on what programming environment you're using.
Here the link to NI's serial support site:
