UEINet 1553 – Data Acquisition and Control Cube

Dual-channel MIL-STD-1553 Interface


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. Each port is transformer coupled, though direct coupling is available as an option.



  • 2 independent dual redundant bus interfaces
  • Bus Controller (BC), Remote Term (RT), or Bus Monitor (BM)
  • Multiple RT simulation up to 31 RT’s
  • Supports 1553A or 1553B protocols (including Notice 2)
  • Independent major and minor frame timing on each port
  • Transformer or direct coupling
  • 350 Vrms isolation between 1553 buses and chassis
  • Selective RT monitoring in BM mode

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.

The UEINet is well suited for the harsh environments sometimes encountered in flight testing applications. The board is specified for operation from -40°C to 50°C (-40°C to 70°C with optional UEINET-FAN), from 0 to 70,000 feet. The system is also fully tested for operation at 5g vibration and up to 100 g shock.
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.
