Register-level programming
You should use the Universal Library to control your board. Only experienced programmers should try registerlevel programming.
If you need to program at the register level in your application, refer to the Register Map for the PCI-DAC6700
Series. This document is available on our website at www.mccdaq.com/registermaps/RegMapPCI-
DAC670x.pdf.

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.
