PARAMETERS

TABLE 9: EEPROM PARAMETERS
The LT2510 utilizes a server-client network architecture to synchronize the frequency hopping. Each network must
have one radio configured as a Server and all other radios configured as Clients. When a radio is configured as a
Server, it will transmit a beacon at the beginning of each hop. Radios configured as Clients will default to a receive
mode where they are scanning the available frequencies listening for a beacon from a Server in their network. When
a Client detects the Server’s beacon, the client will synchronize to it and transition the InRange pin Low. When the
Server and the Client are synchronized they can begin transferring data.
