Chapter 1
Introducing the PCI-DAC6700 Series Boards
Overview: PCI-DAC6700 Series board features
This manual explains how to install and use your PCI-DAC6702, PCI-DAC6703, and
PCI-DAC6704 board. This manual refers to these boards collectively as PCI-DAC6700
Series boards.
PCI-DAC6700 Series boards are high-resolution analog output and digital I/O boards designed for PCI bus-compatible computers. You can use PCI-DAC6700 Series boards for various digital I/O and DC setpoint applications. The channels provided by each board are listed in Ta ble 1-1 .

The voltage output range for each board is ±10.1V volts. The current output range for the PCI-DAC6704 is 0-20 mA.
Each board has eight TTL-compatible digital I/O channels that are configured as one eight-bit port. You can configure each channel individually as either input or output.
Digital channels are configured as inputs by default. Digital bits are pulled up to +5V with 47k resistors. Positions are available for pull-down resistors.
PCI-DAC6700 Series boards feature plug-and-play installation and on-board digital calibration. All I/O signals are transmitted through a 100-pin connector.
PCI-DAC6700 Series boards have a 16-bit digital to analog converter (DAC) that may be periodically updated with new channel data. DAC channel data is stored in nonvolatile RAM (nvRAM). Each channel has a main circuit that maintains the channel value between DAC updates. For the PCI-DAC6704 board, the DAC is multiplexed to create the 16 voltage outputs and 16 current outputs.
PCI-DAC6700 Series boards are equipped with an onboard temperature sensor that measures the air temperature flowing over the board.

Software features–InstaCal
and Universal Library
PCI-DAC6700 Series boards ship with the InstaCal
software configuration utility package. InstaCal is a complete installation, calibration, and test program for data acquisition and control boards. Complete with extensive error checking, InstaCal guides you through the installation and setup of your data acquisition board, and creates the board configuration file for use by your program or application software package. The procedure for installing InstaCal is explained in the Software Installation Manual
(available on our web site at www.mccdaq.com/PDFmanuals/sm-installation.pdf
).
The optional Universal Library™ fully supports the PCI-DAC6700 Series boards. The
Universal Library is a complete set of I/O libraries and drivers for all MCC boards and for all Windows-based languages. When using the Universal Library, you can switch boards or even programming languages, and the syntax remains constant.

Email: [email protected]
Unpacking the board
Each PCI-DAC6700 Series board is shipped in an antistatic container to prevent damage by an electrostatic discharge. To avoid such damage, perform the following procedure when unpacking and handling your board:
1.
Before opening the antistatic container, ground yourself with a wrist-grounding strap or by holding onto a grounded object (such as the computer chassis).
2.
Touch the antistatic container to the computer chassis before removing the board from the container.
3.
Remove the board from the container. Never touch the exposed pins or circuit connections on the board.

PCI-DAC6702/6703/6704 User's Guide Installing the Board
Installing the software
Install the InstaCal software included with your board before you install the hardware. If you ordered the Universal Library software, install that software instead. InstaCal is installed at the same time as the Universal Library.
Installing the software first ensures that the information required for proper board detection is installed and available at boot up. The procedure for installing InstaCal is explained in the Software Installation Manual included with your board (and also available on our web site at www.mccdaq.com/PDFmanuals/sm-installation.pdf
).
If you ordered the Universal Library…
If you ordered the optional Universal Library, use that CD to install both InstaCal and the Universal Library.
Installing the hardware
PCI-DAC6700 Series boards are completely plug-and-play. There are no switches or jumpers to set on these boards. Configuration is controlled by your system's BIOS. To install your board, follow the steps below:
1.
2.
Turn your computer off, open it up, and insert your board into an available PCI slot.
Close your computer and turn it on.
If you are using an operating system with support for plug-and-play (play (such as
Windows 95 or Windows 2000), a dialog box displays 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 InstaCal software 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 you installed in the previous section. Refer to the Software Installation Manual that came with your board ( www.mccdaq.com/PDFmanuals/sm-installation.pdf
) for information on how to initially set up and load InstaCal.
4. 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 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.

Programming and Software Applications
After following the installation instructions in the "
" chapter, your board should now be installed and ready for use.
Programming languages
Measurement Computing’s Universal Library
provides complete access to PCI-
DAC6700 Series board functions from the full range 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. This document is available on our web site at www.mccdaq.com/PDFmanuals/sm-ul-user-guide.pdf
.
Packaged applications programs
Many packaged application programs, such as SoftWIRE
, Labtech Notebook™, and
HP-VEE™, 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.

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, refer to the PCI-DAC6700 Series register map.

Chapter 4
Calibrating the Board
You should calibrate the board using the InstaCal utility software after the board has fully warmed up. The recommended warm-up time is 15 minutes. For best results, calibrate the board immediately before use. The high resolution analog components on the board are temperature-sensitive, so calibrating the board before use ensures that your board is operating with the optimum calibration values. All calibration values are saved in nvRAM.
Calibration theory
InstaCal calibrates the board's analog outputs for offset and gain (see ). A trim
DAC is used to adjust the gain of the DAC. A separate DAC is used to adjust offset on the final output amplifier.
