3. What type of 5 V protection do the VXI-MIO Series modules
have?
The VXI-MIO Series modules have 5 V lines equipped with a
self-resetting 1 A fuse.
4. What jumpers should I be aware of when configuring my
VXI-MIO Series module?
Refer to the Module Configuration section of Chapter 2,
Installation and Configuration, for this information.
5. Which National Instruments document should I read first to get
started using DAQ software?
The release notes document for your application or driver software
is always the best starting place.
6. What version of NI-DAQ must I have to program my
VXI-MIO Series module?
You must have NI-DAQ version 4.9.0 or higher for the
VXI-MIO-64E-1 or VXI-MIO-64XE-10 modules.
7. What is the best way to test my module without having to program
the module?
The NI-DAQ Configuration Utility (formerly WDAQCONF) has a
Test menu with some excellent tools for doing simple functional
tests of the module, such as analog input and output, digital I/O,
and counter/timer tests. Also, the Test Configuration option will
verify that the logical address and interrupt settings for the module
are functioning properly.
8. I'm using my module in differential analog input mode and I have
connected a differential input signal, but my readings are random
and drift rapidly. What's wrong?
Check your ground reference connections. Your signal may be
referenced to a level that is considered floating with reference to
the module ground reference. Even if you are in differential mode,
the signal must still be referenced to the same ground level as the
module reference. There are various methods of achieving this
