The associated broadcast timing process is as follows:
– Step1: The front end processor delivers a timing instruction to the AR500 (Router in
Figure 1-5). The AR500 responds to the timing instruction and adjusts its time.
– Step2: The AR500 determines whether to broadcast the time to connected meters
according to the associated broadcast timing configuration.
– Step3: After broadcast timing is triggered, the AR500 delivers a broadcast timing packet
to all meter channels.
– Step4: After meters receive the broadcast timing packet, they adjust their time according
to the time in the packet. The AR500 does not confirm whether the meter time is
synchronized because the broadcast timing packet does not need to be acknowledged.
