Introducing the PCI-DAS08

Overview: PCI-DAS08 features

This manual explains how to configure, install, and use your PCI-DAS08 board. The PCI-DAS08 is a multifunction measurement and control board designed to operate in computers with PCI bus accessory slots.

The PCI-DAS08 board provides the following features:

• Eight single-ended 12-bit analog inputs
• 12-bit A/D resolution
• Sample rates of up to 40 kHz
• ±5V input range
• Three 16-bit counters
• Seven digital I/O bits (three input, four output)
• Connector compatible with Measurement Computing’s ISA-based CIO-DAS08 board

The PCI-DAS08 board is completely plug-and-play, with no jumpers or switches to set. All board addresses are set by the board’s plug-and-play software.

Software features

For information on the features of InstaCal and the other software included with your PCI-DAS08, 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-DAS08

What comes with your shipment?

The following items are shipped with the PCI-DAS08:

Hardware

• PCI-DAS08

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-DAS08 and information regarding installation of that software. Please read this booklet completely before installing any software or hardware.

Optional components

• Cables

C37FF-x                       C37FFS-x

• Signal termination and conditioning accessories
  MCC provides signal termination products for use with the PCI-DAS08. Refer to the “Field wiring, signal termination and signal conditioning” section for a complete list of compatible accessory products.

Unpacking the PCI-DAS08

As with any electronic device, you should take care while handling to avoid damage from static electricity. Before removing the PCI-DAS08 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: 508-946-5100 and follow the instructions for reaching Tech Support.
• Fax: 508-946-9500 to the attention of Tech Support
• Email: techsupport@mccdaq.com

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 PCI-DAS08

The PCI-DAS08 board is completely plug-and-play. There are no switches or jumpers to set. 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, remove the cover, 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 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. 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.

Configuring the PCI-DAS08

All hardware configuration options on the PCI-DAS08 are software controlled. There are no switches or jumpers to set.

Connecting the board for I/O operations

Connectors, cables – main I/O connector

Table 2-1 lists the board connectors, applicable cables and compatible accessory boards.

Caution! If either the AC or DC voltage is greater than 5 volts, do not connect the PCI-DAS08 to this signal source. You are beyond the board’s usable input range and will need to either adjust your grounding system or add special isolation signal conditioning to take useful measurements. A ground offset voltage of more than 7 volts may damage the PCI-DAS08 board and possibly your computer. An offset voltage much greater than 7 volts will damage your electronics, and may be hazardous to your health.

Field wiring, signal termination and signal conditioning

You can use the following MCC screw terminal boards to terminate field signals and route them into the PCIDAS08 board using the C37FF-x or C37FFS-x cable:

• CIO-MINI37 – 37-pin screw terminal board. Details on this product are available at www.mccdaq.com/cbicatalog/cbiproduct.asp?dept_id=102&pf_id=255.
• SCB-37 – 37 conductor, shielded signal connection/screw terminal box that provides two independent 50pin connections. Details on this product are available at www.mccdaq.com/cbicatalog/cbiproduct.asp?dept_id=196&pf_id=1166.

MCC provides the following analog signal conditioning products for use with your PCI-DAS08 board:

• ISO-RACK08 – Isolated 8-channel, 5B module rack for analog signal conditioning and expansion. Details on this product are available on our web site at www.mccdaq.com/cbicatalog/cbiproduct.asp?dept_id=127&pf_id=449.

Programming and Developing Applications

After following the installation instructions in Chapter 2, your board should now be installed and ready for use. Although the board is part of the larger DAS family, there is no correspondence among registers for different boards. Software written at the register level for other DAS models will not function correctly with the PCIDAS08 board.

Programming languages

Measurement Computing’s Universal LibraryTM provides access to board functions from a variety of Windows programming languages. If you are planning to write programs, or would like to run the example programs for Visual Basic or any other language, refer to the Universal Library User’s Guide (available on our web site at www.mccdaq.com/PDFmanuals/sm-ul-user- guide.pdf).

Packaged application programs

Many packaged application programs, such as SoftWIRE and HP-VEETM, now have drivers for your board. If the package you own does not have drivers for the board, please fax or e-mail the package name and the revision number from the install disks. We will research the package for you and advise how to obtain drivers.

Some application drivers are included with the Universal Library package, but not with the application package. If you have purchased an application package directly from the software vendor, you may need to purchase our Universal Library and drivers. Please contact us by phone, fax or e-mail:

• Phone: 508-946-5100 and follow the instructions for reaching Tech Support.
• Fax: 508-946-9500 to the attention of Tech Support
• Email: techsupport@mccdaq.com

Register-level programming

You should use the Universal Library or one of the packaged application programs mentioned above to control your board. Only experienced programmers should try register-level programming.

If you need to program at the register level in your application, you can find more information in the Register Map for the PCI-DAS08 Series (available at www.mccdaq.com/registermaps/RegMapPCI- DAS08.pdf).
