AT-AO-6

The National Instruments AT-AO-6 is a legacy analog output board with six 12-bit analog output channels and eight digital I/O lines. NI's NI-DAQ 7.4 documentation lists it as a Traditional NI-DAQ (Legacy) device rather than an NI-DAQmx device.

Overview

Product overview

Key product information and technical features.

The AT-AO-6 belongs to NI's legacy ISA/PC/AT equipment range. Its six analog output channels are numbered 0 through 5, with 12-bit double-buffered digital-to-analog conversion.

NI's archived hardware-capability tables document voltage and current output ranges, buffered waveform output, and internal or external update timing. Software integration requires attention to the legacy driver API: the NI-DAQ 7.4 readme explicitly excludes this model from NI-DAQmx support.

  • Six analog output channels with 12-bit DAC resolution.
  • Eight digital I/O lines alongside the analog outputs.
  • Double-buffered DAC architecture with a 1 K FIFO for update-clock-1 channels.
  • External update-clock operation through the EXTUPDATE* signal.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

How many analog output channels does the AT-AO-6 provide?

It provides six 12-bit analog output channels, numbered 0 through 5, plus eight digital I/O lines.

Does NI-DAQmx support the AT-AO-6?

NI's NI-DAQ 7.4 readme explicitly lists the AT-AO-6 as unsupported by NI-DAQmx and supported only through Traditional NI-DAQ (Legacy) in that release.

Can the AT-AO-6 use an external update clock?

Yes. NI's archived Data Acquisition Basics Manual identifies EXTUPDATE* as the external update-clock input signal for AT-AO-6/10 devices.
