United Electronic Industries (UEI) in Walpole, Mass., is introducing the DNR-12-1G Ethernet I/O chassisotherwise known as the RACKtangle. Based on the UEI Cube I/O chassis, the rectangular form factor increases the number of I/O slots from six to 12 in a rugged 3U chassis. As the RACKtangle is electrically compatible with the Cube form factors, all of the I/O boards available in the Cube form factor are also available for the RACKtangle. The RACKtangle’s I/O slots provide as many as 300 analog inputs, 384 analog outputs, 576 digital I/O, 96 counter or quadrature channels, 144 ARINC-429 channels, and/or 48 serial or CAN-bus ports. Software for the RACKtangle comes in the UEIDAQ Framework, which provides API that supports popular programming and operating systems including Windows, Vista, Linux, QNX, RTX, and RT Linux. The board is supported by LabVIEW, MATLAB/Simulink, DASYLab, or any application supporting ActiveX, OPC, or Modbus TCP control. For more information, visit UEI online at www.ueidaq.com.
