Run the diagnostic utility, as follows: select 
Start»Programs»National Instruments Serial»diagnostics.

The diagnostic utility verifies that your serial driver is installed 
properly, that the configuration of your hardware does not conflict 
with anything else in your system, and that the serial driver can 
communicate with your hardware correctly.

If the test is successful, your serial hardware and software are installed 
properly. If the test fails, refer to Appendix C, 

, to troubleshoot the problem.

After you verify the hardware and software installation, continue to the next 
section, Connect the Cables.

For the two-port PCI serial boards, you can use the standard 
DB-9 connector found on most serial cables. To use the DB-9 connector 
with the four-port PCI serial boards, you need the 10-position modular jack 
to DB-9 cable, which is available from National Instruments. You can also 
use a DB-25 connector with the four-port PCI serial boards by ordering the 
10-position modular jack to DB-25 converter cable from National 
Instruments. The eight-port PCI serial boards include a pig tail cable 
adapter, providing eight standard DB-9 connectors. The 16-port board 
includes a break out box, providing 16 standard DB-9 connectors.

To achieve the specified isolation voltage for four-port isolated PCI serial boards, 

use only the 10-position modular jack to DB-9 cable that is included in your four-port 
isolated PCI serial board kit.
