Abstract
A method of limiting read/write access of information stored on an electronic trip unit is disclosed. The method includes requesting a valid password on one of a communication port of the electronic trip unit and a display device of the electronic trip unit, receiving a password at a processor of the electronic trip unit in response to the request, determining if the received password is valid based on password information stored on a memory of the electronic trip unit, and limiting read/write access of information stored on the electronic trip unit based on the determination.
