Common Questions

This appendix lists common questions related to the use of the SCXI-1503.
Which version of NI-DAQ works with the SCXI-1503, and how do I get
the most current version of NI-DAQ?
You must have NI-DAQ 8.1 or later. Visit the NI Web site at ni.com and
select Download Software»Drivers and Updates»Search Drivers and
Updates. Enter the keyword NI-DAQ to find the latest version of NI-DAQ
for your operating system.
I cannot correctly test and verify that my SCXI-1503 is working. What
should I do?
Unfortunately, there is always the chance that one or more components in
the system are not operating correctly. You may have to callor email a
technical support representative. The technical support representative often
suggests troubleshooting measures. If requesting technical support by
phone, have the system nearby so you can try these measures immediately.
NI contact information is listed in the Technical Support Information
document.
Can the SCXI-1503 current outputs be interactively controlled in
MAX or programmatically controlled using NI-DAQ function calls,
LabVIEW, or Measurement Studio?
No. The current-output level is 100μA as long as t he chassis is powered on.
You cannot power off or adjust the current output using MAX, NI-DAQ
function calls, or an ADE such as LabVIEW or Measurement Studio. If you
require this functionality, consider using an SCXI-1124 module or NI 670X
device instead.
How can I ground a floating voltage measurement?
You can use the IEX– terminal of each channel as a ground reference. Refer
to the SCXI-1306 Terminal Block Installation Guide for details about using
the SCXI-1306 DIP switches to control ground referencing.
