Introducing the PCI-DAC6700 Series Boards

Overview: PCI-DAC6700 Series board features

This manual explains how to install and use your PCI-DAC6702 and PCI-DAC6703 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 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-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.
PCI-DAC6700 Series boards are equipped with an onboard temperature sensor that measures the air
temperature flowing over the board.
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.
