The test probes connect to the DAQCard-4050 accessory cable via
shrouded banana jacks. The shrouds around the banana jacks prevent
you from contacting potentially hazardous voltages connected to the
test probes. You can also connect the cable to standard (unshrouded)
banana jack probes or accessories; however, use unshrouded probes or
accessories only when the voltages are less than 30 V
rms
or 42 V
pk-to-pk
.
You can use the measurement ends of the test probes in either of two
ways, as shown in Figure 2-2. With the plastic covers over the ends, you
can use the probes to directly probe the circuit or device to be tested.
With the plastic tip covers removed, the test probes can accept standard
banana jack accessories (such as spade lugs, alligator clips, or spring
clips), which are available from National Instruments.

Hardware Configuration
The DAQCard-4050 is a fully software-configurable, Plug and Play
device. Configuration information is stored in nonvolatile memory. The
Plug and Play services query the device, read the information, and
arbitrate resource allocation for items such as base address and interrupt
level. After assigning these resources, the operating system enables the
device for operation.
