METHOD AND APPARATUS FOR REPEATING ILLUMINATION INFORMATION ON A DAISY CHAIN BUS STRUCTURE
First Claim
1. A data communication method for transmitting a data packet comprising data bytes in a daisy chained bus structure of a LED illumination system, the method comprising:
- the nodes of a group, except the last node of the group retransmitting the data packet without removing a first data byte from the incoming data packet; and
the last node in the group removing the first byte from the data packet before retransmission.

Abstract
A data communication method is described for transmitting a data packet comprising data bytes in a daisy chained bus structure of a LED illumination system. The method comprises: the nodes of a group, except the last node of the group retransmitting the data packet without removing a first data byte from the incoming data packet; and the last node in the group removing the first byte from the data packet before retransmission. The invention further comprises a communication node, illumination assembly and bus structure implementing the method according to the invention.

- 14. A communication node for a DMX communication network, the node comprising an input for receiving a data packet comprising data bytes and an output for retransmitting the data packet to a following node, wherein the data packet is retransmitted without removal of a first data byte of the incoming data packet.

16. A bus structure comprising a plurality of nodes, each node comprising an input for receiving a data packet comprising data bytes and an output for retransmitting the data packet to a following node, wherein individual nodes are arranged for removing a first data byte from the data packet before retransmission, while a plurality of nodes forming a group, the nodes in the group, except the last one, exhibiting a different behavior than the individual nodes in that they are arranged for retransmitting the incoming data packet without removal of the first data byte from the data packet.
