DIO-128 Dynamic Digital I/O System

DIO-128 makes it easy to navigate to digital transitions. Even in a sea of data.

High Performance Digital Timing Analysis
The DIO-128 allows you to easily record and timestamp state changes on 128+ digital inputs in LabVIEW® for Windows 95, 98, 2000 or Windows NT. The DSP control program for the DIO-128 system allows the board to monitor a large number of digital channels and return a timestamp and the status of all digital lines when any one of the digital lines change state. If no state change occurs, no data is sampled. This prevents collecting large quantities of data when no events are occurring. By specifying the digital lines that can trigger a sample, state changes on other lines can be ignored. This allows you to acquire data only when state changes occur on lines that are of interest to you.

High Performance Digital Stimulus
The DIO-128 allows you to easily create and execute complex patterns on up to 64 digital output channels. By only specifying the timestamp and state of channels that change, it is much simpler to create complex patterns for devices under test. The DIO-128 provides for a large FIFO that can replay the desired patterns continuously or for a limited number of repetitions. Combine the Digital Timing Analysis and Digital Stimulus modes for a flexible, high performance digital test system.

Custom Applications Provide Ultimate Flexibility
Since the functions of the DIO-128 board are determined by the DSP control program, a huge variety of other digital tasks including digital output, continuous waveform generation, and fixed rate digital input are possible. Contact Viewpoint Systems for information on solving your specific digital applications with a custom DSP control program.

Application Possibilities

• Motion Quality Measurement
  Characterize motion throughout a mechanical system by comparing multiple encoders for vibration, slippage, and jitter. Couple a DIO-128 Dynamic Digital I/O System with a Viewpoint Motion Goto! motion system for a complete motion quality measurement system!
  
  
• High Channel Density Digital I/O System
  128, 256, 384... channel, high resolution acquisition that does not overburden the application with unnecessary data. Coordinate multi-board systems with clocks and triggers over the RTSI interface.
  
  
• Demanding Digital Pattern Stimulus System
  The DIO-128 provides more flexibility than counter-based solutions and requires much less data acquisition throughput than traditional "dumb" digital interface cards.
  
  
• DIO-128 Features
  • Intelligence: Analog Devices ADSP-2181 16 MHz DSP capable of 32 MIPS.
  • High speed: The DIO-128 can measure time intervals as short as 500 nanoseconds.
  • High channel count: 128 channels with 64 available for output.
  • RTSI interface: Allows for multi-board triggers and clocks.
  • Signal Conditioning: Use with Viewpoint's Opto32-128 optically isolated digital input conditioning board.
  • Driver software with useful example programs included.

The DIO-128 Advantage
A typical "dumb" digital I/O card will sample and attempt to save data at every clock tick. The DIO-128 will sample at every tick, but save the data only when the signal has changed. This drastically reduces the amount of data that needs to be transferred and processed by the application.
