Chapter 1
Introducing the PCI-DAS64/M2/16
Overview: PCI-DAS64/M2/16 features
The PCI-DAS64/M2/16 board offers a combination of high speed, channel count and resolution on a single
PCI-bus data acquisition board. It offers:
!
!
!
!
!
!
!
64 single-ended or 32 differential 16-bit analog inputs
2 MHz sample rate
Two 16-bit analog outputs
100 kHz D/A update rate (16 K FIFO)
32 bits of digital I/O
One 16-bit down-counter
A variety of analog and digital trigger modes with software-selectable trigger levels and direction
The PCI-DAS64/M2/16 board is designed with Measurement Computing’s powerful System Timing Controller
(STC) chip. The STC chip controls all A/D sampling and D/A update rates as well as controlling the 8K A/D
FIFO, the 8K gain/channel queue and the 16K D/A FIFO buffer. This functionality is based on the STC chip’s
use of an on-board 32K x 16 SRAM. The STC chip assigns functions to various parts of the SRAM, such as the
A/D FIFO buffer, and provides full-speed control and arbitration among the various functions using the various
sections of the SRAM buffer.
The STC allows simultaneous full speed A/D sampling, D/A updating and gain/channel queue sequencing, with
variable inter-sample timing if desired. The STC chip performs these functions up to 5 MHz, and is available as
an OEM component for use in your own designs. The board provides bus-mastering and scatter-gather
functionality to assure the desired system timing is maintained.
The PCI-DAS64/M2/16 is completely plug-and-play, with no switches, jumpers or potentiometers on the board.
All board addresses, interrupt channels, etc., are set by your computers plug-and-play software. Calibration is
performed via software by using on-board trim D/A converters.
Software features
For information on the features of InstaCal and the other software included with your PCI-DAS64/M2/16, refer
to the Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at

Installing the software
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-
Installing the PCI-DAS64/M2/16
The PCI-DAS64/M2/16 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 pops up 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 will be prompted for the disk
containing this file. The MCC DAQ software contains this file. If required, insert the Measurement
Computing Data Acquisition Software CD and click OK.
3. To test your installation and configure your board, run the InstaCal utility you 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
60 minutes before acquiring data. This warm-up period is required 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.

PCI-DAS64/M2/16 User's Guide
Installing the PCI-DAS64/M2/16
Calibrate the PCI-DAS64/M2/16 after it has warmed up and immediately before making critical
measurements
Use the InstaCal utility to calibrate the PCI-DAS64/M2/16 after it has fully warmed up. For best results,
calibrate the board immediately before making critical measurements. The high resolution analog components
on the board are somewhat sensitive to temperature. This pre-measurement calibration insures that your board is
operating at the optimum calibration values.
Configuring the PCI-DAS64/M2/16
All hardware configuration options on the PCI-DAS64/M2/16 are software controlled. You can select some of
the configuration options using InstaCal, such as the analog input configuration (64 single-ended or 32
differential channels), and the edge used for triggering when using an external pacer.
Once configured, any program that uses Measurement Computing’s Universal Library will initialize the
hardware according to these selections.

Pin out – auxiliary DIO connector
The auxiliary digital connector can be accessed using a variety of cabling schemes. To bring the 40-pin header
out to a bracket at the back of the PC, use a BP40-37 adapter. This terminates in a CIO-DIO series compatible
connector to which you can connect a CIO-MINI37 or CIO-TERMINAL screw terminal board using a C37FF-x
or C37FFS-x cable. Other options include direct cabling using a C40-37F-x (which maintains CIO-DIO
compatibility), or using the C40FF-x cable with the CIO-MINI40 screw terminal board.

Analog inputs
The PCI-DAS64/M2/16 provides 32 fully differential or 64 single-ended analog inputs. The input mode is
software selectable, with no switches or jumpers to set. The PCI-DAS64/M2/16 offers a 2 MHz sample rate.
The board offers full speed acquisition in single channel scans, and will perform full accuracy multi-channel
scans of up to 1.5 MHz, depending on the operating mode. An 8 K sample gain/channel queue is available
making long, complex sample sequencing simple. An 8 K sample FIFO buffer combines with Bus-Master DMA
and scatter-gather to assure data taken from the board is transferred into computer memory without missing
samples.

Burst mode
Channel-to-channel skew is the result of multiplexing the A/D inputs. It is defined as the time between
consecutive samples. Burst mode minimizes channel-to-channel skew by clocking the A/D at a high rate
between successive samples within a scan, then waiting a specified time before starting a new scan. The PCI-
DAS64/M2/16 provides burst mode with a 667 ns minimum sample skew/delay.
Analog output
The PCI-DAS64/M2/16 board provides two high-speed, ±5V 16-bit analog outputs. The outputs are updated via
on-board 16 K FIFO buffer and provide a 100 kHz (max) update rate. Repetitive D/A-based waveforms can be
stored in on-board memory and generated without requiring ongoing PCI bus transfers. The outputs provide
rated accuracy to ±15 mA, are short-circuit-protected (25 mA limit) and are cleared to 0 volts on power-up or
reset. The board supports simultaneous full speed operation of both the A/D and D/A.
Digital I/O
The PCI-DAS64/M2/16 provides 32 bits of digital I/O. An 82C55 chip provides 24 bits of CMOS compatible
I/O at the board’s 40-pin auxiliary digital connector. Four LSTTL-compatible digital inputs and four outputs are
provided on the main 100-pin connector. On power up or reset, all I/O ports default to the input state (high
impedance).
Counter/timer I/O
The PCI-DAS64/M2/16 provides one 16-bit down counter (1/3 of an 82C54). Clock, gate and output
connections are available at the 100-pin user I/O connector.

Chapter 5
Calibrating the PCI-DAS64/M2/16
Overview
The PCI-DAS64/M2/16 provides self-calibration of the analog inputs and outputs, eliminating the need for
external equipment and user adjustments. All adjustments are made via 8-bit calibration DACs which are
referenced to an on-board factory-calibrated standard. The board is fully calibrated at the factory with
calibration coefficients stored in nvRAM. At run time, these calibration factors are loaded into system memory
and are automatically retrieved each time you specify a different DAC/ADC range.
You can recalibrate any time using factory voltage standards by selecting the Calibrate option in InstaCal. A
full calibration typically requires less than two minutes. We strongly recommend that you turn your computer
on, and allow at least 60 minutes for the internal computer case temperature to stabilize prior to calibrating (or
acquiring data with) the board.
A/D calibration is performed at user-selectable conversion frequencies. This is required to reduce any
frequency-dependent offset effects across the operating range. When you pull down the Calibrate menu option
and click on A/D, a dialog opens for you to select a calibration frequency (see Figure 5-1). We recommend that
you select a frequency as close as possible to the applications’ sampling frequency.
Figure 5-1. InstaCal Calibration Frequency dialog
Table 5-1 lists the available calibration frequencies and recommended sampling frequency ranges. Using this
table as a guide, a ±1 LSB offset error relative to the calibrated offset is maintained over a given sampling
frequency range. We recommend that you perform A/D calibration at 100 kHz if you intend to use the entire
sampling frequency range but do not want to re-calibrate for a given sampling frequency span. In that case, you
can expect a ±6 LSB offset drift with respect to the calibrated offset over the full 10 Hz to 2 MHz range.

For best results, calibrate the board immediately prior to making your measurements. The high-resolution
analog components on the board are somewhat sensitive to temperature and this pre-measurement calibration
helps assure your board operates at the same temperature at which it was calibrated.
Calibration theory
Offset calibration for the analog front end is performed via adjustments of the ADC itself. Front-end gain
adjustment is performed only via the ADC reference. This strategy was chosen since the gain tolerance of the
in-amp circuit is quite good and there is adequate gain tuning range using only the ADC.
A block diagram of the analog front-end calibration system is shown in Figure 5-2.

Calibrating the PCI-DAS64/M2/16
The analog output circuits are calibrated for gain and offset. Gain calibration of the analog outputs is performed
via DAC reference adjustments. Offset adjustments for the analog outputs are made in the output buffer section.
The tuning range of this adjustment yields maximum DAC and output buffer offsets.

As shown in Table 5, 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 can be calculated by summing these
component errors. Worst-case errors are realized only in the unlikely event that each of the component errors
are at their maximum level, and causing error in the same direction.
Crosstalk
Crosstalk is defined here as the influence of one channel upon another when scanning two channels at the
maximum rate. A full-scale 100 Hz triangle wave is input on channel 1, and channel 0 is tied to analog ground
at the 100-pin user connector. Table 6 summarizes the influence of channel 1 on channel 0 with the effects of
noise removed. The residue on channel 0 is described in LSBs.

Table 8 summarizes the worst case noise performance for the PCI-DAS64/M2/16. Noise distribution is
determined by gathering 50 K samples with inputs tied to ground at the user connector. Samples are gathered at
the maximum specified single-channel sampling rate. Specification applies to both single-ended and differential
modes of operation.
