Chapter 1
Introducing the PCI-DAC6702 and PCI-DAC6703
Overview: PCI-DAC6702 and PCI-DAC6703 features
This manual explains how to install and use your PCI-DAC6702 or PCI-DAC6703 board.
PCI-DAC6702 and PCI-DAC6703 boards are high-resolution analog output and digital I/O boards designed for
PCI bus-compatible computers. You can use PCI-DAC6702 and PCI-DAC6703 boards for various digital I/O
and DC setpoint applications.
The PCI-DAC6702 provides 8 analog outputs, and the PCI-DAC6703 provides 16 analog outputs. The voltage
output range for each board is ±10.1V volts.
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-DAC6702 and PCI-DAC6703 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.
PCI-DAC6702 and PCI-DAC6703 boards are equipped with an onboard temperature sensor that measures the
air temperature flowing over the board.
Each board features plug-and-play installation and on-board digital calibration. All I/O signals are transmitted
through a 100-pin connector.

Signal termination and conditioning accessories
MCC provides signal termination products for use with the PCI-DAC6702 and PCI-DAC6703. Refer to the
"Field wiring and signal termination accessories" section page 16 for a complete list of compatible accessory
products.
Unpacking the PCI-DAC6702 and PCI-DAC6703
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-DAC6702 and PCI-DAC6703 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: [e-mail]
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-DAC6702 and PCI-DAC6703
PCI-DAC6702 and PCI-DAC6703 boards are 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 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 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.

Chapter 3
Calibrating the PCI-DAC6702 and PCI-DAC6703
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 Figure 4). 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.

Calibration schedule
You should calibrate your PCI-DAC6702 and PCI-DAC6703 board once per year using InstaCal's calibration
procedures.
