NI 6584

RS-485/RS-422 Adapter Module for NI FlexRIO

Configure Page for: Print PDF Rich Text
  • Up to 16 Mbits/s data rates
  • 16 RS-485/RS-422 compatible channels
  • Mates with an NI FlexRIO FPGA module for reliable and deterministic control of digital communication
  • Half or Full Duplex
  • 100 Ohm terminated or no termination options


You can use this adapter module with an NI FlexRIO FPGA module for customized, bit-level access to RS-485/RS-422. With this combination, you can implement customized RS-485/RS-422 communication or real-time analysis on the FPGA.

The NI 6584 is available in both half and full duplex. The half duplex module shares TX and RX pairs, thus allowing you to transmit or receive individually on that channel. Full duplex on the other hand has separate TX and RX pairs allowing you to transmit and receive simultaneously.

System Assurance Programs

Reduce your setup time and total cost of ownership, and get a system you can use out of the box with National Instruments system assurance programs. System assurance programs include:

  • Installation and integration test of all individual hardware
  • Courtesy installation of system driver sets and application development environments
  • Extended warranty and calibration coverage for up to five years
  • Custom documentation plus a custom restore and startup utility

This service is only available for PXI, NI CompactRIO, and NI Compact FieldPoint systems.

Extended Warranties

National Instruments designs and manufactures all products to minimize failures, however unexpected failures can still occur. Extended warranties provide a fixed economical price at the time of system purchase, covering any repair costs for up to three years. In addition, they offer the following benefits:

  • Significant cost savings compared to individual repair incidents
  • Fault location, diagnostics, and repair by NI any time the system product fails
  • All parts and labor costs covered as well as any adjustments needed to restore the hardware to manufacturing specifications

For more information about your warranty options:

Calibration

NI recognizes the need to maintain properly calibrated devices for high-accuracy measurements. NI provides manual calibration procedures, services to recalibrate your products, and automated calibration software to calibrate many NI measurement products.

Training

NI training is the fastest, most certain route to productivity with NI tools and successful application development.

Repair Services

Return your registered product under warranty at no additional labor and parts cost. NI offers fault location, diagnostics, and repair any time the system fails as well as any adjustments needed to restore the hardware to manufacturing specifications.
