  • Page 9: Rf Hop Frame

    Read Flash RF Hop Frame The RM024 hops every 13.19 milliseconds and can be configured for two different RF data rates to provide options for range or throughput. During each hop, the RM024 reserves a certain amount of time for overhead such as the synchronization beacon, internal messaging, and user data transmission.
