The CIO-DAS16/330i multifunction analog and digital I/O board is designed to be a modern improvement upon the traditional DAS-16 architecture with higher speed and additional features, all at a lower cost.
Beyond the 64K Barrier
The CIO-DAS16/330i acquires sample sets of greater than 32K samples (64KB of memory) by
employing advanced instructions; just as do LAN and hard disk controllers. Although transfers to
array variables are still limited to 64KB, samples may be streamed to
data files far in excess of 64K using the free streaming software supplied.
Two Modes
On power up, the CIO-DAS16/330i is software compatible with the
older, original architecture shared by the DAS-16. In this mode all old
DAS-16 type software runs and the new advanced registers are invisible
to the PC bus. Set one special control bit and supercharge the CIO-DAS16/330i! In special mode,
a new set of registers open up that allow A/D transfers up to 330KHz, and pre/post trigger buffers.
Analog Inputs
The analog input section of the CIO-DAS16/330i has been designed for high speed, flexibility and accuracy
in a number of configurations and ranges. The analog signals are brought on board by a standard
37 pin D connector directly to two multiplexors. The two multiplexors may be configured as 16 channels
of single ended input or 8 channels of differential input. Differential inputs
can reject noise and ground loops (common mode voltages) but require a 3 wire hookup as opposed to 2.
Input ranges are: +/- 10 V, +/- 5 V, +/- 2.5 V, +/- 1.25 V, +/- 0.625 V, 0 to 10 V,
0 to 5 V, 0 to 2.5 V and 0 to 1.25 V.
Simultaneous Sample and Hold
Capture 16 channels simultaneously with less than 50 ns of aperture uncertainty at 130 kHz. The
CIO-SSH16 expands the CIO-DAS16-330i's 16 single ended, multiplexed inputs into 16 fully
differential inputs with individual, switch selectable gains of up to
800 on every channel. No software modifications are required to realize the benefits of simultaneous sample
and hold.
Software
A test and setup software is provided called Instacal, which allows immediate verification, setup and calibration.
An optional driver is available called UNIV-DRVR for $49, for programming in Dos and Windows with programs such as C
, Visual Basic and other popular languages.
