describes the optional software and optional equipment, and explains how
to unpack your 671X device.
About the 671 X Devices
Thank you for buying a National Instruments 671X device. Your 671X
device is a completely Plug and Play, analog output, digital, and timing I/O
device for PXI/PCI/CompactPCI, 1394, or PCMCIA (PC Card) bus. The
671X device features a 12-bit digital-to-analog converter (DAC) per
channel with update rates up to 1 MS/s/channel for voltage outputs, eight
lines of TTL-compatible digital I/O, and two 24-bit counter/timers for
timing I/O. The 6711 device features four voltage output channels, while
the 6713 and 6715 devices feature eight voltage output channels. Because
the 671X device has no DIP switches, jumpers, or potentiometers, it is
easily software-configured and calibrated.
The 6711/6713 device is a completely switchless and jumperless data
acquisition (DAQ) device for the PXI/PCI/CompactPCI or 1394 bus. This
feature is made possible by the National Instruments MITE bus interface
chip that connects the device to the PCI I/O bus. The MITE implements the
PCI Local Bus Specification so that the interrupts and base memory
addresses are all software configured.
The 6715 device is a completely switchless and jumperless data acquisition
(DAQ) device for the PCMCIA (PC Card) bus and is Plug and Play
software configurable.
The 671X device uses the National Instruments DAQ-STC system timing
controller for time-related functions. The DAQ-STC consists of three
timing groups that control analog input, analog output, and general-purpose
counter/timer functions. These groups include a total of seven 24-bit and
three 16-bit counters and a maximum timing resolution of 50 ns. The
analog input section of the DAQ-STC is unused by the 671X.
