This chapter describes the VXI-MIO Series modules, lists what you
need to get started, describes the optional software and optional
equipment, and explains how to unpack your VXI-MIO Series module.
About the VXI-MIO Series
Thank you for buying a National Instruments VXI-MIO Series module.
The VXI-MIO Series modules are completely VXI
plug&play
-
compatible multifunction analog, digital, and timing I/O modules for
VXIbus. This family of modules features 12-bit and 16-bit ADCs with
64 analog inputs, 12-bit and 16-bit DACs with voltage outputs, eight
lines of TTL-compatible digital I/O, and two 24-bit counter/timers for
timing I/O.
The VXI-MIO Series modules use the National Instruments DAQ-STC
system timing controller for timer-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.
A common problem with other VXI modules is that you cannot easily
synchronize several measurement functions to a common trigger or
timing event. The VXI-MIO Series modules solve this problem by
using VXIbus triggers to synchronize measurements on several
VXI-MIO Series modules.
You can interface the VXI-MIO Series modules to an SCXI signal
conditioning and multiplexing system to acquire over 3,000 analog
signals from thermocouples, RTDs, strain gauges, voltage sources, and
current sources
.
You can also acquire or generate digital signals for
communication and control.
