Abstract

In order to enable the information contained in an identification connector to be read in a manner that is more reliable, faster, and without risk of damage, the invention provides a reader appliance for reading identification connectors for airplane engines, the connector comprising a plurality of contacts connected to a decoding circuit, each contact corresponding to a binary digit, one or more of the binary digits corresponding to information relating to characteristics of the engine. The reader appliance comprises connection means suitable for receiving at least one identification connector, the connection means being connected to processor means responding to control members in order to display on a display device the information contained in the connector.

Claims

1. A reader appliance for reading identification connectors for airplane engines, said connector comprising a plurality of contacts connected to a decoding circuit, each contact corresponding to a binary digit, one or more of said binary digits corresponding to information relating to characteristics of the engine,
