TABLE 5: TIMING SPECIFICATIONS
RF HOP FRAME
The LT2510 will hop every 13.19ms and can be configured for two different RF Data Rates to provide
options for range or throughput. During each hop, the LT2510 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 will only begin 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.
