CIO-DAS1600 Series From $599
High Speed 16-Channel 12-
or 16-Bit Multifunction Board
The CIO-DAS1600 series are multifunction analog and digital I/O boards for IBM PC and compatible computers. The boards feature 16 single-ended or 8 differential analog inputs, 2 analog outputs, 32 digital I/O and 3 counter/timers (2 used for A/D timing). The CIO-DAS1600 is designed to be 100% compatible with the popular DAS-1600 series. It maintains full compatibility while providing several enhancements including a 512 sample FIFO buffer, DT-connect for high speed inter-board communication and improved A/D triggering.
The CIO-DAS1600 turns your personal computer into a high-speed data acquisition and control station suitable for laboratory data collection, instrumentation, product test, or industrial monitoring. There are several different models available, they are described in the table below:
| RANGE TABLE | ||||

330,000 | 1, 2, 4 & 8 | 0-10V, 0-5V, 0-2.5V, 0-1.25V +10V, +5V, +2.5V, +1.25V, |
| CIO-DAS1602-16 | 16 bit (1 part in 65,536) |
100,000 | 1, 2, 4 & 8 | 0-10V, 0-5V, 0-2.5V, 0-1.25V +10V, +5V, +2.5V, +1.25V, |
*Range selection is accomplished by a combination of bipolar/unipolar switch and software programmable gain amplifier.
Analog Inputs
The analog input section of the CIO-DAS1600 has been
designed for flexibility an accuracy in a number of
configurations. A standard 37 pin D connector brings the analog
signals directly into two multiplexer. The two muliplexers may be
configured as 16 channels of single-ended input of 8 channels of
differential input. A programmable gain amplifier amplifies the
signals before entering the A/D converter. The data throughput
rate is dependent on the method of triggering and data transfer.
FIFO Provides Full Data Rate Under Windows
All boards in the CIO-DAS1600 family include a 512-sample FIFO
buffer. The FIFO buffer collects the results of A/D conversions
and stores then until the computer's CPU is able to transfer the
data into PC memory. The FIFO buffer allows the PC to store up
the A/D transfer requests, then service the requests in batches.
The FIFO is necessary to obtain the full data acquisition rates
under multitasking operating systems like windows.
The best part about the FIFO buffer is transparency; software you have written for the DAS-1600 or CIO-DAS16 will run on a CIO-DAS1600 at higher speed without modification. And you will not miss a sample.
DT-Connect
The CIO-DAS1600 boards can transfer A/D conversions to the PC via
the ISA bus, or to other boards via DT-Connect. The DT-Connect
board-to-board interface is a standard employed by a number of
data acquisition, array and signal processing companies. OMEGA
makes the MEGA-FIFO sample buffer board which holds up 128
million samples of memory completley freeing the PC bus from data
transfer overhead.
Minimizing Channel to Channel Skew
All of the channels on the CIO-DAS1600 are multiplexed into a
single A/D converter. Since there is only one A/D converter on
the board, a channel to channel time skew (delay) occurs when
scanning multiple channels. With many A/D boards, the time skew
is equal to the sample rate, so a 1 KHz sample rate would produce
a 1 millisecond skew time. The CIO-DAS1600 features an enhance
triggering mode called the burst mode. In the bust mode, the A/D
converter is run at its maximum rate for the entire multi-channel
scan, thus reducing the channel to channel skew time to the
maximum A/D rate which is 3.3╡S for the 12-bit boards and 10╡S
for the 16-bit board.
If less skew is required, the optional CIO-SSH16 simultaneous sample and hold accessory board can be used to reduce the channel-to-channel time skew to 0 with 50 nS aperture uncertainly.
Analog Outputs
Two 12-bit multiplying D/A converters provide a analog
voltage output. This type of converter accepts a reference
voltage an provides an output proportional to the reference
voltage. A precision -5V an -10V reference provide on-board D/A
ranges of 0-5V, 0-10 V, +5 V, and + 10V. Other
ranges between + 10 V are possible with the use of an
external reference.
The D/A converts provide program and interrupt transfer capability. Interrupts may be initiated by the on-board pacer clock or by external trigger.
Digital I/O
The CIO-DAS1600 provides 32 channels of digital I/O. Eight
channels of I/O are accessed through the main connector. These
channels are fixed as 4 inputs and 4 outputs. There is also a
second auxiliary digital I/O connector that contains 24 digital
I/O lines (these channels are not present on the =P5 version).
The digital I/O on this connector are arranged as two 8-bit and
two 4-bit banks. Each bank may be configured through software as
an input or output.
-P5 Option for Obstructed Computer Slots
The CIO-DAS1600 requires a full size computer expansion slot. The
-P5 version of the board is used in computer systems where the
expansion slot is obstructed and cannot accommodate the full
board. The version contains only the eight fixed digital I/O
channels on the main connector; the auxiliary digital I/O
channels are not present.
Software
The CIO-DAS1600 includes a complete test and calibration
program. The program provides a step-by-step procedure for
installing and configuring the card. It also creates a
configuration file used by the optional Universal Library.
The Universal Library is a set of I/O libraries and drivers for those users creating their own custom programs. The Universal Library is compatible with most DOS and Windows based languages and supports the entire CIO family of boards. The library includes an extensive set of programming examples written in Visual Basic, C and Pascal for both Windows and DOS languages.
An optional driver for LabView is also available. The LabView driver works in conjunction with the Universal Library, so both are needed to use the CIO-DAS1600 in LabView.
The CIO-DAS1600 is also comptabile with many off-the-shelf programs including Labtech, DASYLab and Snapmaster.
