Digital and Timing I/O
In addition to the analog input and analog output capabilities of the AT-MIO-64F-5, the
AT-MIO-64F-5 also has eight digital I/O lines that can sink up to 24 mA of current, and three
independent 16-bit counter/timers for frequency counting, event counting, and pulse output
applications. The AT-MIO-64F-5 has timer-generated interrupts, a high-performance RTSI bus
interface, and four triggers for system-level timing.
Figure 1-1 shows the AT-MIO-64F-5 board.

You can use the AT-MIO-64F-5 with its multifunction analog, digital, and timing I/O in many
applications, including machine and process control automation, level monitoring and control,
instrumentation, electronic testing, and many others. You can use the multichannel analog input
for signal and transient analysis, data logging, and chromatography. The two analog output
channels are useful for machine and process control, analog function generation, 12-bit
resolution voltage source, and programmable signal attenuation. You can use the eight
TTL-compatible digital I/O lines for machine and process control, intermachine communication,
and relay switching control. The three 16-bit counter/timers are useful for such functions as
pulse and clock generation, timed control of laboratory equipment, and frequency, event, and
pulse width measurement. With all these functions on one board, you can automatically monitor
and control laboratory processes.
The AT-MIO-64F-5 is interfaced to the National Instruments RTSI bus. With this bus, National
Instruments AT Series boards can send timing signals to each other. The AT-MIO-64F-5 can
send signals from the onboard counter/timer to another board, or another board can control single
and multiple A/D conversions on the AT-MIO-64F-5.
Detailed specifications for the AT-MIO-64F-5 are listed in Appendix A, Specifications.
