Installing the PCI-DAS1602/12
The PCI-DAS1602/12 board is completely plug-and-play, with no switches or jumpers to set. Configuration is
controlled by your system's BIOS. To install your board, follow the steps below.
Install the MCC DAQ software before you install your board
The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install
the MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on
installing the software.
1. Turn your computer off, open it up, and insert your board into an available PCI slot.
2. Close your computer and turn it on.
If you are using an operating system with support for plug-and-play (such as Windows 2000 or
Windows XP), a dialog box opens as the system loads, indicating that new hardware has been detected. If
the information file for this board is not already loaded onto your PC, you are prompted for the disk
containing this file. The Measurement Computing Data Acquisition Software CD supplied with your board
contains this file. If required, insert the disk or CD and click OK.
3. To test your installation and configure your board, run the InstaCal utility installed in the previous section.
Refer to the Quick Start Guide that came with your board for information on how to initially set up and
load InstaCal.
If your board has been powered-off for more than 10 minutes, allow your computer to warm up for at least
15 minutes before acquiring data with this board. This warm-up period is required in order for the board to
achieve its rated accuracy. The high speed components used on the board generate heat, and it takes this
amount of time for a board to reach steady state if it has been powered off for a significant amount of time

16-channel single-ended mode pin out
The signal names for pins 2 to 17 define the functions for both single-ended modes and also for differential
input modes. For example, if you are using eight differential inputs, pin 2 is the high side of channel 0
(CH0 HI) and pin 3 is the low side (CH0 LO) of channel 0. If you are using single-ended inputs, pin 2 is
channel 0 (CH0 HI), but pin 3 is now channel 8 (CH8 HI). When you use single-ended inputs, use LLGND
(and not GND) for analog signal returns.
Cabling
You can use a C100FF-x cable to connect signals to the PCI-DAS1602/12 board. The C100FF-x cable is made
up of two 50-pin ribbon cables that are joined at one end with a 100-pin connector. The two 50-pin cables
diverge and are terminated at the other end with standard 50-pin header connectors.

The first 50-pin connector is used primarily for analog signals (pins 1-50 of the 100-pin connector). The second
50-pin connector is used primarily for digital I/O signals (pins 51-100 of the 100-pin connector). This
configuration minimizes noise in the analog signal lines, and greatly simplifies field wiring and connections to
external devices. You can purchase C100FF-x series cables from our web site at
www.mccdaq.com/products/accessories.aspx.
Field wiring and signal termination
You can use the following MCC screw terminal boards to terminate field signals and route them into the PCIDAS1602/12 board using the C100FF-x cable:
Screw terminal boards
CIO-TERM100 – 100 pin, 16 x 4 screw terminal board.
CIO-MINI50 – 50-pin universal screw terminal accessory. Two boards are required.
SCB-50 – 50-conductor, shielded signal connection/screw terminal box providing two independent 50-pin
Details on these products are available at www.mccdaq.com/products/screw_terminal_bnc.aspx.
Details on these products are available at www.mccdaq.com/products/signal_conditioning.aspx.
Digital signal conditioning
The following digital signal conditioning products have 37-pin connectors. Use the DADP-5037 adaptor board
for connections to the C100FF-x cable's 50-pin connectors.
SSR-RACK24 – 24-position solid state relay rack. The DADP-5037 adaptor board is required.
SSR-RACK08 – Eight-channel solid state relay rack. The DADP-5037 with TN-MC78M05CT adaptor
board is required.

adaptor board is required.
CIO-ERB08 – Eight-channel electromechanical relay accessory for digital I/O boards. The DADP-5037
adaptor board is required.
Details on digital signal conditioning products are available at
www.mccdaq.com/products/signal_conditioning.aspx. Details on the DADP-5037 adapter board are available
at www.mccdaq.com/products/accessories.aspx.
Caution! Before connecting signals to the PCI-DAS1602/12, measure the voltage between ground at the
signal source and ground at the PC. If you measure >10 volts, do not connect the board to this
signal source, as you are beyond the usable input range of the board. Either adjust your grounding
system or add isolation signal conditioning to take useful measurements. A ground offset voltage
of more than 30 volts may damage the board and possibly your computer. An offset voltage much
greater than 30 volts will damage your electronics, and may be hazardous to your health.
To terminate signals and route them into the PCI-DAS1602/12, use the SCB-50 signal connection box,
CIO-TERM100 screw terminal board, or two CIO-MINI50 screw terminal boards.

Analog inputs
The PCI-DAS1602/12 provides eight differential inputs, or 16 single-ended analog inputs. The input mode is
software selectable, with no switches or jumpers to set. The board offers a 330 kHz maximum sample rate in
single and multi-channel scans at any gain setting. A 1024 sample FIFO assures data taken from the board is
transferred into computer memory without the possibility of missed samples.
Software also selects the bipolar/unipolar input configuration as well as selecting among the input ranges. The
table below lists the input ranges and resolutions for the available input configurations and gains.
Input range and resolution
Burst mode
Channel-to-channel skew results from multiplexing the A/D inputs. Channel-to-channel skew is defined as the
time between consecutive samples. For example, if four channels are sampled at a rate of 1 kHz per channel,
the channel skew is 250 µs (1 ms/4).
Burst mode minimizes channel-to-channel skew by clocking the A/D at the maximum rate between successive
channels. Burst mode timing is illustrated in Figure 4. At the 1-ms pulse, channel 0 is sampled. After 3 µs,
channel 2 is sampled. Channel 3 is sampled 3 µs after channel 2 is sampled. No samples are then taken until the
next 1-ms pulse, when channel 0 is sampled again. In this mode, the rate for all channels is 1 kHz, but the
channel-to-channel skew (delay) is now 3 µs, or 9 µs total. The minimum burst mode skew/delay on the PCIDAS1602/12 is 3 µs.

Analog outputs
The PCI-DAS1602/12 provides two channels of high-speed 12-bit analog output. The analog outputs are
updated via an on-board FIFO and REP OUTSW commands and provide a 250 kHz maximum update rate.
Software selectable output ranges are 0 to 10 V, 0 to 5 V, ±10 V, and ±5 V. Channels may be set at different
ranges. The D/A outputs provide rated accuracy to ±5 mA, are short circuit protected (25 mA limit) and are
cleared to 0 volts on power up or reset.
Parallel digital I/O
The PCI-DAS1602/12 provides 24 bits of parallel, digital I/O in the form of two eight-bit ports, and two fourbit ports. This digital capability is based on an on-board 82C55 PIA chip, which allows each of the ports to be
set independently as input or output. The ports default to the input state (high impedance) on power up or reset.
Counter/timer I/O
The PCI-DAS1602/12 provides three 16-bit down counters (one third of an 82C54 chip). The counters provide
clock, gate and output connections. The counter clock may also be connected to the on-board 10 MHz crystal
oscillator or may be left uncommitted for user input.

Calibrating the PCI-DAS1602/12
The PCI-DAS1602/12 is equipped with software auto calibration. The InstaCal software makes gain and offset
corrections to the board using on-board digital potentiometers and trim D/A converters. No user intervention or
external equipment is required. The PCI-DAS1602/16 is shipped fully-calibrated from the factory.
All adjustments are made via 8-bit calibration DACs or 7-bit digital potentiometers that are referenced to an onboard factory calibrated standard. Calibration factors are stored on the serial nvRAM. At run time, these
calibration factors can be loaded into system memory and can be automatically retrieved when a different
DAC/ADC range is specified
You can recalibrate with respect to the factory-measured voltage standards at any time by selecting the
Calibrate menu in InstaCal. Full calibration requires less than two minutes and requires no external equipment
or user adjustments.
The standard calibration involves calibrating one channel with 0 volts input (offset), and then with a known
input voltage (gain). The PCI-DAS1602/12's on board circuitry first shorts the inputs for offset calibration, then
connects the inputs to the ultra-stable precision voltage reference for the gain calibration.
Analog input calibration
Analog inputs are calibrated for offset and gain. Offset calibration is performed in the instrumentation amplifier
gain stage. Front-end gain adjustment is performed via a variable attenuator/gain stage.
The analog input calibration system is shown in Figure 5.

Analog output calibration
Analog output circuits are calibrated for offset and gain. Coarse and fine offset adjustments are made in the
output buffer section. The tuning range of these adjustments allows for maximum DAC and output buffer
offsets. Coarse and fine gain calibration is performed via adjustments to the DAC reference.
The analog output calibration system is shown in Figure 6. This circuit is duplicated for both DAC0 and DAC1.

Table 3. Accuracy components (errors in LSBs)
Each PCI-DAS1602/12 is tested at the factory to assure the board’s overall error does not exceed accuracy
limits described in Table 2.
As shown in Table 3, total board error is a combination of gain, offset, differential linearity error (DLE) and
integral linearity error (ILE). The theoretical worst-case error of the board may be calculated by summing these
component errors. Worst case errors are realized only in the unlikely event that each of the component errors is
at their maximum level, and causing error in the same direction.

Table 8. Accuracy components (errors in LSBs)
Each PCI-DAS1602/12 is tested at the factory to assure the board’s overall error does not exceed ±3.0 LSB.
Total board error is a combination of gain, offset, integral linearity and differential linearity error. The
theoretical worst-case error of the board may be calculated by summing these component errors. Worst case
error is realized only in the unlikely event that each of the component errors are at their maximum level, and
causing error in the same direction. Although an examination of the chart and a summation of the maximum
theoretical errors shows that the board could theoretically exhibit a ±4.4 LSB error, our testing assures this
error is never realized in a board that we ship.
