Analysis for the Fault Caused by Two Different Formats of Bus Data Delivery

摘要

The electronic programmable controller of a fighter can receive the RS429 signal from atmospheric system, meanwhile it can transform the signal to RS422, but the indicator light indicates abnormal. The fault caused by the electronic programmable controller is found when it transforms the signal from the atmospheric system to the wrong format. The data formats of the RS429 and the RS422 are analyzed, the root cause and a solution to this problem are derived.
