Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data
Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-

Quick-Start.pdf.

Configuring the CIO-DAS1401/12

The CIO-DAS1401/12 has one base address switch, one input configuration switch, one interrupt level jumper,
and one wait state jumper which you must set before installing the board in your computer. The InstaCal
calibration and test program included with the CIO-DAS1401/12 will show you how to set the switches. Run
InstaCal before you open your computer and install the board. The CIO-DAS1401/12 is shipped with the
factory-default settings listed below.

Factory-configured default settings

Before installing the CIO-DAS1401/12, verify that the board is configured with the settings that you want.
Review the following information to change the default configuration of a jumper or switch on the CIO­DAS1401/12 board.

Base address

Before you install the CIO-DAS1401/12 in your computer, set the base address by using the dip switch labeled

ADDRESS located on the board. The easiest way to set the base address switch is to let InstaCal show you the

correct settings. However, if are already familiar with setting ISA base addresses, you may use the base address
switch description below to guide your base address selection.

Unless there is already another board in your system using address 300 hex (768 decimal), leave the switches as
they are set at the factory. The example shown in Figure 1 shows the settings for the factory-default base
address of 300 hex.

Figure 1. Base address switches

In the default configuration shown in Figure 1, addresses 9 and 8 are DOWN, and all others are UP.
Address 9 = 200 hex (512 decimal) and address 8 = 100 hex (256 decimal); when added together they equal
300 hex (768 decimal).

Note: Wait State Enable is typically not required. Leave the WAIT EN switch in the UP position (not enabled).

Disregard the numbers printed on the switch

When setting the base address, refer to the numbers printed in white on the printed circuit board.

DMA level

Use the DMA level switch (S7) to select a level of 1 or 3. The default setting is level 1 (see Figure 2). There are
other boards that use DMA levels, such as some network boards and IEEE-488 interface boards. Check to see if
you have other boards in your computer that use DMA channels 1 or 3.

Figure 2. DMA level switch

1/10 Clock frequency

Use the clock frequency XTAL jumper to select the frequency of the square wave used as a clock by the A/D
pacer circuitry. You can select either 1 MHz or 10 MHz. The pacer circuitry controls the sample timing of the
A/D. The output driving the A/D converter is also available at the CTR2 Out pin on the main connector.

To maintain full compatibility with the original DAS-16, the CIO-DAS1401/12 required a 1 MHz crystal
oscillator. When MetraByte redesigned the DAS-16 and added the faster 10 MHz crystal, a jumper was
provided to maintain compatibility with older software. The CIO-DAS1401/12 has the jumper because the
DAS-16 has the jumper. For older software, the jumper must be in the 1 MHz position. If you are not
concerned with compatibility with older software, use the 10 MHz position.

The CIO-DAS1401/12 is shipped with the jumper in the 1 MHz position (see Figure 3).

8/16 Channel mode

Use the channel select switch to configure the analog inputs for eight differential or 16 single-ended inputs. Use
the single-ended input mode if you have more than eight, low-noise analog inputs to sample. Using the
differential input mode allows up to 10 volts of common mode noise rejection.

The CIO-DAS1401/12 is shipped with this switch set for 16 single-ended mode(see Figure 4). Set it for the
type (or number) of inputs you require.

Figure 4. 8/16 Channel mode switch

Bipolar/Unipolar mode

Use the Bipolar/Unipolar select switch to select the polarity of the A/D converter.

The CIO-DAS1401/12 is shipped with this switch set for Bipolar (see Figure 5). The switch controls all A/D
channels. You cannot mix bipolar and unipolar channels, however you can measure a unipolar input in the
bipolar mode — for example, you can monitor a 0 to 5V input with a ±5 V channel.

Figure 5. Bipolar/Unipolar switch

Input amplifier gain is controlled by a software-programmed register located at Base + B hex (11 decimal).
Refer to the Register Map for the CIO-DAS1400 Series at www.mccdaq.com/registermaps/RegMapCIO-

DAS140x.pdf for details on this register.

Pacer edge

The original Keithley MetraByte DAS-1600 was designed such that A/D conversion initiated on the falling
(trailing) edge of the convert signal from the internal pacer. Neither the original DAS-16, nor any of the other
DAS-16 derivations convert on the falling edge.

When using the falling edge to start the conversion, the A/D may be falsely triggered by 8254 pacer clock
initialization glitching (easy to avoid but a real possibility in the DAS-1600). Converting on the falling edge
mode also may lead to timing differences if the CIO-DAS1401/12 board is used as a replacement for an older
DAS16 series board.

Because using the falling edge trigger is undesirable, the CIO-DAS1401/12 has a jumper which allows you to
select the internal pacer signal edge used to start the A/D conversion. The jumper has no effect on an external
pacer signal (EXTCLOCK). The falling edge trigger option is provided for compatibility with software for a
DAS-1600 using the AS-1600 drivers, AND, if you observe sample timing differences when using the CIO­DAS1401/12 with that software.

Functional Details

Auxiliary trigger

There is a position for a header connector at the rear of the CIO-DAS1401/12. This connector provides the
same function as that found on the DAS-1600.

The A/D trigger signal may come from this connector, if installed. A jumper controls which pin the trigger
signal comes in from. We do not install this connector (nor is it installed on the DAS-1600).

Burst mode generator

The burst mode generator is a clock signal that paces the A/D at the maximum multi-channel sample rate, and
periodically performs additional maximum-rate scans. In this way, the channel-to-channel skew (time between
successive samples in a scan) are minimized without taking a large number of undesired samples (see Figure 8).

Figure 8. Burst mode generator timing

The CIO-DAS1401/12 burst mode generator takes advantage of the fast A/D. The burst mode skew is 4 µs.

Calibration and test

Every board is fully tested and calibrated before shipment. For normal environments, a calibration interval of
six months to one year is recommended. If frequent variations in temperature or humidity are common,
recalibrate with InstaCal at least every three months. It takes less than 20 minutes to calibrate the CIO­DAS1401/12.

Required equipment

Ideally, you will need a precision voltage source, or a non precision source and a 4½ digit digital voltmeter, and
a few pieces of wire.

You do not need an extender card to calibrate the board, but you do need to remove the cover from your
computer to adjust trim pots during calibration.

14

CIO-DAS1401/12User's Guide Functional Details

Note: Use the plastic screwdriver supplied with your board for adjusting the trim pots, so that if the screwdriver

is dropped into the PC, it won’t cause a short circuit.

Calibrating the A/D converters

The A/D is calibrated by applying a known voltage to an analog input channel and adjusting trim pots for offset
and gain. There are three trim pots requiring adjustment to calibrate the analog input section of the board. There
are also three pots associated with each of the analog output channels.

Calibrate the board for the range you intend to use it in. When the range is changed, slight variation in Zero and
Full Scale may result. These variations can be measured and removed in software, if necessary.
