NI 6731/6733
The following sections contain more information on the NI 6731/6733.
Features (NI 6731/6733)
The NI 6731/6733 are Plug-and-Play, analog output (AO), digital I/O (DIO), and timing I/O
(TIO) devices for PCI bus computers. The NI 6731 features:
•
four AO channels with 16-bit resolution
•
eight lines of TTL-compatible DIO
•
two 24-bit counter/timers for TIO
•
a 68-pin AO I/O connector
The NI 6733 features:
•
eight AO channels with 16-bit resolution
•
eight lines of TTL-compatible DIO
•
two 24-bit counter/timers for TIO
•
a 68-pin AO I/O connector
Because the NI 6731/6733 have no DIP switches, jumpers, or potentiometers, they are easily
software-configured and calibrated.
For the NI 6731/6733 connector pinouts, refer to Chapter 2,
Analog Output (NI 6731/6733)
The NI 6731 has four channels of voltage output at the I/O connector, and the NI 6733 has eight
channels of voltage output at the I/O connector. The reference for the AO circuitry is
software-selectable per channel. The reference can be either internal or external, but the range is
always bipolar. This means that you can generate signals up to ±10 V with internal reference
selected or ±EXT REF voltage with external reference selected.
