Digital I/O Connector

© National Instruments Corporation
All digital I/O is transmitted through a standard, 100-pin, female connector
for the DAQPad-6508 or 100-pin screw terminal with a strain-relief clamp
for the DAQPad-6507. Pins 49 and 99 are connected to +5 V through a
self-restarting protection fuse (F1). See Figure 4-1 for its location. This
+5 V supply is often required to operate I/O module mounting racks.
Pins 50 and 100 are connected to ground. See the
section in Chapter 1, Introduction, as well as Chapter 2,
Configuration, and the
Chapter 3, Signal Connections, for additional information.
