DNx-1553-553 – Dual Channel MIL-STD-1553 interface board

Dual Channel MIL-STD-1553 interface board for Cube I/O chassis


The DNx-1553-553 is a high performance, two channel MIL-STD-1553 interface. Each channel operates fully independently and provides a complete dual, redundant MIL STD 1553 interface.



  • 2 Independent, dual redundant bus interfaces
  • Bus Controller (BC), Remote Terminal (RT) or Bus Monitor (MT) modes
  • Multiple RT simulation up to 32 RTs
  • Supports 1553A or 1553B protocols (including notice 2)
  • Transformer or Direct Coupling

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 be set at a single RT address, or to emulate the entire bus up to 32 different RTs.

Bus Monitoring (BM) mode provides the ability to monitor all activity, or selective activity based upon RT address.

When installed in the Cube, the DNA-1553-553 is well suited for the harsh environments sometimes encountered in flight testing applications. The board is specified for operation from -40° to +85° C, from 0 to 70,000 feet. The system is also fully tested for operation at 5g vibration and up to 50 g shock.
