Corporate Timeline


  • UEI moves to a new facility in Walpole, Massachusetts. The larger, 19,000 square footfacility will allow for sustained growth and expansion for the company.
  • UEI Releases the UEIModbus Series of data acquisition Cubes designed to communicate with a host computer or PLC over Modbus TCP. Using the UEIModbus, the technology behind the PowerDNA Cube is put to work in industrial applications where Modbus is still the dominant communications protocol.
  • UEI Releases the UEIPAC series of Programmable Automation Controllers or PACs. Using a Linux OS, and based on the same technology as the PowerDNA Cube, the UEIPAC is a compact, rugged, and flexible, I/O controller, ideal for use in huge number of applications.
  • UEI Releases PowerDNA cubes with 100BASE-FX fiber optical Ethernet interface extending the maximum distance between the PowerDNA Cube, and its host computer from 100 meters (w/100BASE-T) to 2 kilometers with multimode fiber, and 20 kilometers with single mode fiber.


  • UEI releases the UEILogger. Based upon the PowerDNA Cube, the UEILogger is extremely powerful and flexible. The Logger allows users to install up to six different I/O boards in a single logger cube. This provides an unprecedented ability to match the logger hardware to customers’ applications. Programming the logger is simple with the intuitive Windows application provided. The new logger stores data on standard SD Cards containing up to 4 gigabytes of data.
  • UEI is awarded a patent for the DAQBios protocol. The new protocol allows Ethernet-based PowerDNA cubes to provide guaranteed real-time response of less than 1 millisecond over 1000 analog or digital I/O points.
  • UEI continues to release new I/O boards for the PowerDNA (and now UEILogger, UEIPAC, and UEIModbus) product families. New boards include a 4 port CAN interface, a 4 port RS-232/422/485 interface and a family of 16-bit analog output boards with output currents as high as ±50 mA and output voltages as high as ±40V.


  • UEI announces a new series of PowerDNA cubes based upon a new, powerful PowerPC CPU. The new cubes more than double the I/O capability of the cube. UEI continues to release new I/O boards/layers for the PowerDNA family. New boards include a counter/timer board that supports quadrature encoder measurements and a strain gage input board.
  • UEI also dramatically enhances its software offering by releasing an OPC server application supporting the PowerDNA and PowerDAQ, a Linux 2.2 driver for PowerDNA and support for Mathworks’ Linux version of Simulink


  • UEI releases a host of new I/O boards in support of its growing PowerDNA family of Ethernet based I/O cubes. Software is created that allows users to host PowerDNA based systems on both Windows and Linux platforms. APIs for UEI’s Ethernet-based PowerDNA family and PCI/PXI based PowerDAQ family are consolidated allowing code written for one platform to also support the other


  • UEI branches out into distributed I/O systems with PowerDNA, which provides exceptional hard realtime performance on Ethernet systems at an extremely attractive price point. The realtime performance is possible thanks to UEI’s patent-pending DaqBIOS protocol, which allows the servicing of more than a thousand I/O points over an Ethernet network in < 1 msec.


  • UEI expands on its industry-leading software support with several key products:
    • LabVIEW for Linux: With this driver, users can collect real-world data into a LabVIEW application that is running under Linux. Not even National Instruments provides this level of support.
    • LabVIEW Real-Time: Users are no longer locked into working with just one company when configuring a LabVIEW Real-Time system. These free drivers allow any of UEI’s PXI cards to function within that environment, giving users an attractively priced alternative.
    • xPC Target: The MathWorks sells a combination development environment/execution system for realtime applications. UEI joins the few select firms with drivers that support the xPC Target.
