Data bus systems as defined in MIL-STD-1553B are widely used in aerospace instrumentation systems for digital data transmissions between units on the bus. Although the bus is protected against a short circuit which may occur in the remote unit electronics or transformer, it has no protection against a cable termination failure. Open or short failure along main bus cable results in failure of the entire bus system. A data bus interface technique is described which is insensitive to cable termination failure. The key to this technique is a directional coupling transformer which is only slightly more complicated than standard interface transformers. Design equations for the directional coupling transformer and experimental results of new data bus systems are presented.
