your computer.
2.
Run
, which is in the
visaconf

230.4 kbits/s for RS-232.
My application worked with a board interface, but it times out when
I use the serial device server interface. What should I do?
Because the serial device server is a network device, it is dependent on
network conditions for timely communications. An unpredictable delay
is associated with using the remote serial ports. Applications may require
longer serial timeouts to compensate for this delay. However, different
applications handle serial timeouts differently, and each must be adjusted
individually to account for your network conditions.
What do I do if diagnostics shows errors?
Refer to the troubleshooting sections of this appendix for specific
information about what might cause diagnostics to show errors. If you
already have completed the troubleshooting steps, contact National
Instruments.
How do I communicate with my instrument over the serial bus?
Refer to the documentation that came from the instrument manufacturer.
The command sequences you use are dependent on the specific instrument.
The documentation for each instrument should include the serial
commands you need to communicate with it.
