Chapter 1
Introducing the PCI-DAS1200/JR
Overview: PCI-DAS1200/JR features
This manual explains how to install and use the PCI-DAS1200/JR board. The PCI-DAS1200/JR board is a
multifunction measurement and control board designed for the PCI bus.
The PCI-DAS1200/JR provides eight differential or 16 single-ended 12-bit analog inputs, with sample rates of
up to 330 kHz. Input ranges are either bipolar or unipolar. Bipolar input ranges are ±10V, ±5V, ±2.5V, and
±1.25V. Unipolar input ranges are 0 to 10V, 0 to 5V, 0 to 2.5V, and 0 to 1.25V. All input ranges are software-
selectable.
The PCI-DAS1200/JR has 24-bits of parallel, digital I/O as two 8-bit ports and two 4-bit ports. Each port can be
configured independently as input or output.
The PCI-DAS1200/JR board contains an 82C54 counter chip, which consists of three 16-bit counters. Clock,
gate, and output signals from two of the three counters are available on a 100-pin I/O connector. The third
counter is used internally.
Software features
For information on the features of InstaCal and the other software included with your PCI-DAS1200/JR, refer
to the Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at
www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf.
Check www.mccdaq.com/download.htm for the latest software version or versions of the software supported
under less commonly used operating systems.

Installing the PCI-DAS1200/JR
What is included with your PCI-DAS1200/JR
As you unpack your board, make sure each of the items shown below is included:
Hardware
PCI-DAS1200/JR board
Additional documentation
In addition to this hardware user's guide, you should also receive the Quick Start Guide (available in PDF at
www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf). This booklet supplies a brief description of
the software you received with your PCI-DAS1200/JR and information regarding installation of that software.
Please read this booklet completely before installing any software or hardware.
Optional components
If you ordered any of the following products with your board, they should be included with your shipment.
C100FF-x cable

Signal termination and conditioning accessories
MCC provides signal termination products for use with the PCI-DAS1200/JR. Refer to Field wiring and
signal termination accessories on page 15 for a complete list of compatible accessory products.
Unpacking the PCI-DAS1200/JR
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-DAS1200/JR from its packaging, ground yourself using a wrist strap or by
simply touching the computer chassis or other grounded object to eliminate any stored static charge.
If any components are missing or damaged, notify Measurement Computing Corporation immediately by
phone, fax, or e-mail:
Phone: [phone] and follow the instructions for reaching Tech Support.
Fax: [phone] to the attention of Tech Support
Email: [email protected]
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-
Quick-Start.pdf.
Installing the hardware
PCI-DAS1200/JR board is completely plug-and-play. There are 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 www.mccdaq.com/PDFmanuals/DAQ-
Software-Quick-Start.pdf for information on how to initially set up and load InstaCal.
Allow your computer to warm up for at least 15 minutes before acquiring data with this board. The high speed
components used on the board generates 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.

Configuring the hardware
All hardware configuration options on the PCI-DAS1200/JR are software controlled. You can select some of
the configuration options using InstaCal, such as the analog input configuration (16 single-ended or eight
differential channels) and the source for the two independent counters. Once selected, any program that uses the
Universal Library will initialize the hardware according to these selections.
Differential input mode
When all channels are configured for differential input mode, eight analog input channels are available. In this
mode, the input signal is measured with respect to the low input. The input signal is delivered through three
wires:
The wire carrying the signal to be measured connects to CH# IN HI.
The wire carrying the reference signal connects to CH# IN LO.
The third wire is connected to LLGND.
Differential input mode is the preferred configuration for applications in noisy environments, or when the signal
source is referenced to a potential other than PC ground.
Single-ended input mode
When all channels are configured for single-ended input mode, 16 analog input channels are available. In this
mode, the input signal is referenced to the board’s signal ground (LLGND). The input signal is delivered
through two wires:
The wire carrying the signal to be measured connects to CH# IN HI.
The second wire is connected to LLGND.
Connecting the board for I/O operations
All I/O signals are brought through a 100-pin high-density connector. The C100FF-x cable is used to connect
field signals to the board. This cable has a pair of 50-pin ribbon cables that are joined at one end to a 100-pin
connector. The first 50-pin cable (pins 1-50) carries the analog signals. The second 50-pin cable (pins 51-100)
carries the digital signals. The 100-pin connector mates with the PCI-DAS1200/JR connector. The two 50-pin
ribbon cables are terminated with standard 50-pin header connectors.

Chapter 3
Calibrating the board
Introduction
Calibrate the board using InstaCal after the board has fully warmed up. The recommended warm-up time is
15 minutes. For best results, calibrate the board immediately before making critical measurements. The high
resolution analog components on the board are sensitive to temperature. Pre-measurement calibration ensures
that your board is operating at optimum calibration values.
Calibration theory
The PCI-DAS1200/JR is shipped fully calibrated from the factory. Calibration coefficients are stored in
nvRAM. When using the Universal Library at run time, these calibration factors are loaded into system memory
and automatically retrieved each time you specify a different DAC/ADC range.
The analog input circuits are calibrated for offset and gain (Figure 3).
Offset calibration for the analog input is performed directly on the input amplifier (PGIA) with coarse and
fine trim DACs acting on the amplifier.
For input gain calibration, a precision calibration reference is used with coarse and fine trim DACs acting
on the ADC.
