The UEINet 1553 is a high performance, two channel MIL-STD-1553 interface. Each port operates fully independently and provides a complete dual, redundant 1553 interface and may be set as 1553a or 1553b. The "b" interface fully implements specification notices 1 and 2. Each port is transformer coupled, though direct coupling is available as an option.
Many 1553 functions are implemented in an on-board FPGA. This greatly reduces the burden placed on the chassis CPU and ensures the 1553 functionality does not limit the the processor interface or the connectivity to the host PC.
Each port may be independently configured as Bus Controller (BC), Remote Terminal (RT) or Bus Monitor (BM). As Bus Controller, the board supports all standard BC-RT, RT-BC and RT-RT transfers. The Remote Terminal support allows the board to emulate up to 31 different RTs on the bus. Bus Monitoring (BM) mode provides the ability to monitor all activity, or selective activity based upon RT address. In addition to monitoring data, BM monitors time tags, error status and RT response time. Finally, each DNA-1553-553 channel may be set to simultaneously act as an RT and BM or BC and BM.
The UEINet is well suited for the harsh environments sometimes encountered in flight testing applications. The board is specified for operation from -40º to +85ºC, from 0 to 70,000 feet. The system is also fully tested for operation at 5g vibration and up to 100 g shock.
The UEINet 1553 includes a standard MIL-1553 cable interface. Also included is a helpful, self-test loop-back adaptor.
Software included with the UEINet 1553 includes our 1553 API, designed to offer simple, easy-to-use controls and yet maintain the ability to access all 1553 functionality. The software driver is compatible with all popular operating systems including Windows Vista and XP and Linux as well as most real-time OS's such as INtime, QNX, RT Linux and more. Software support is also included for all popular programming languages and data acquisition (DAQ) application packages including LabVIEW and MATLAB.
