This chapter describes your PCI/PXI-6711/6713 device, lists what you need to get started, describes the optional software and optional equipment, and explains how to unpack your 6711/6713 device. About the 6711/6713 Devices Thank you for buying a National Instruments 6711/6713 device. Your 6711/6713 device is a completely Plug and Play, analog output, digital, and timing I/O device for PXI/PCI/CompactPCI. The 6711/6713 device features a 12-bit digital-to-analog converter (DAC) per channel with update rates up to 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 device features eight voltage output channels. Because the 6711/6713 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. 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 6711/6713 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 6711/6713. Often with other DAQ devices, you cannot easily synchronize several measurement functions to a common trigger or timing event. The PCI-6711/6713 device has the Real-Time System Integration (RTSI) bus to solve this problem. The RTSI bus consists of our RTSI bus interface and a ribbon cable to route timing and trigger signals between several functions Chapter 1 Introduction PCI/PXI-6711/6713 User Manual 1-2 © National Instruments Corporation on as many as five DAQ devices in your computer. If you are using the PXI-6711/6713 in a PXI chassis, RTSI lines, known as the PXI trigger bus, are part of the backplane, therefore you do not need the RTSI cable for system triggering and timing on the PXI. Detailed specifications of the 6711/6713 device are in Appendix A, Specifications.
