Patent ID: 7447238

Claim:
A method for compensating for one or more transmission delays between a multiplexer, a first node and a second node, comprising: calculating a transmission delay between the multiplexer and the first node using an equation (RTC K +Delay K )mod(M·T slot )=(K−1)·T slot , where M refers to the number of time slots within a bandwidth of a medium configured for communicating data between the multiplexer, the first node and the second node, T slot refers to the duration of each time slot, K refers to a node address, mod refers to a modulo operation, RTC K refers to the real time clock of the K th node and Delay K refers to accumulated transmission delay from the multiplexer to the K th node; sending the real time clock of the multiplexer, a first number and the transmission delay to the first node; and setting the real time clock of the first node to be equal to the real time clock of the multiplexer plus the transmission delay.
