C.4SYNCHRONIZATION
To synchronize the date and time of a relay we use a command with the following characteristics:
1. The command is executed in broadcast mode (relay address = 00H)
2. Date and time are included in the message. The date and time format length is 6 bytes.
3. No answer is expected from the relay.
