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.
