Engineering Design Program: Engine Communications Card

Abstract

The “Honeywell Engine Communications Card” provides a common interface between a memory bus and several signals while providing several features. The inputs signals will be transmitted in parallel. The Engine Communications Card will transmit several protocols include CAN, ARINC 429, RS-485/422, MIL-STD-1553, and Ethernet. The Engine Communications Card will have a chassis resilient to vibrations and fluctuating temperature. The Engine Communications Card is modular so that one or more of the input signals may be missing without affecting the operation of the card. Additionally, the Engine Communications Card circuit design is such that if a protocol is removed at board printing time, the Integrated Circuit chip responsible for that protocol can be left off the board as a cost saving measure. During runtime, any number of protocols can be shut off without affecting the performance of the system.
