RF Hop Frame

The RM024 hops every 13.19 ms 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. The diagrams below outline the various transmissions that occur during a hop. These
transmissions are transparent to the user sending data, but may be useful for applications that
require critical timing. User data is only transmitted during the data slots and after the Interface
Timeout or RF Packet Size criteria has been met. Data transmission only begins at the beginning
of a data slot. When configured for Full Duplex, data slot 1 is reserved for the server and data slot
2 is shared by all clients for transmissions.
