48-Bit Isolated Digital I/O
48-Bit Isolated Digital I/O
By default, the solid-state relays power up open (digital lines high).
You can configure the power-up state of each output line
independently with a software utility located in the Developer Zone.

I/O Connector
The I/O connector for an NI 6527 is a 100-pin female connector, and
the pinout is shown in Figure 1. For a shielded cable/accessory
combination, use the SH100-100-F cable with the SCB-100
accessory. NI 6527 devices are also compatible with the CB-100 kit,
which includes two 50-pin connector blocks and ribbon cable.
For 5 V nonisolated applications, the +5 V and GND lines from
the computer, available on the I/O connector, eliminate the need for
an external power supply.

Driver Software
With NI-DAQ driver software,
you can interactively configure
your devices, write custom
programs, and easily perform
digital I/O. You can also
use change notification and
messaging so that when a
line state change is detected,
the software can perform
another programmed operation.
Change notification eliminates
polling, decreases the load
on the CPU and bus, and
improves the efficiency of the
system. NI-DAQ also provides
numerous example programs
for LabVIEW and other
development environments to
quickly get you started with
your application.
