USB Plug and Play Comes to the NI LabVIEW RIO Architecture

November 4, 2013. National Instruments has announced four new R Series boards (USB-7855R, USB-7856R, USB-7855R OEM, and USB-7856R OEM) with USB connectivity, which help engineers add FPGA technology to any PC-based system using one of the most widely adopted buses on the market. These products, based on the LabVIEW RIO architecture, are a result of the company’s continued investment in the R Series product family.

The LabVIEW RIO architecture is an integral part of the NI graphical system design platform. A modern approach to designing, prototyping, and deploying embedded monitoring and control systems, graphical system design combines the open NI LabVIEW graphical programming environment with commercial off-the-shelf hardware to dramatically simplify development, which results in higher-quality designs with the ability to incorporate custom design.

“Using these new USB R Series devices, engineers and scientists can create highly customizable measurement and control systems using standard PC technology,” said Jamie Smith, director of embedded systems marketing at National Instruments. “They are ideal for high-performance medical, life science, and semiconductor machines.”

The devices employ Xilinx Kintex-7 FPGAs to implement tasks like custom timing and triggering, synchronization, multirate sampling, high-speed control, and onboard signal processing.

Improved I/O takes advantage of analog input and analog output rates of up to 1 MHz for closed-loop control tasks, as well as digital I/O (DIO) rates of up to 80 MHz. Selectable logic levels from 1.2 to 3.3 V enable users to adjust DIO levels to meet specific application requirements. Selectable gain for analog input ranges enables more resolution at lower voltage ranges. OEM options are available; users can select a board-only form factor with the flexibility to create their own I/O interface.
