Why is the standard based on the Lenz system instead of one of the other existing systems?
In drafting the standard, we looked at various alternatives including existing approaches and completely new designs. After careful study, the committee found that the signaling techniques used by a system designed by Lenz Elektronik, a German electronics firm, far exceeded our list of requirements and employed a communication protocol that offered the greatest future growth potential. While we based the signaling techniques on the Lenz design, we made numerous improvements and created a packet format that is much richer in features provided. See the questions in the operation section for more details.
