  • Page 10: Rf Hop Frame

    Image 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.

    RXD and TXD The RM024 accepts 3.3 VDC TTL level asynchronous serial data from the OEM host via the RXD pin. Data is sent from the transceiver, at 3.3 V levels, to the OEM host via the TXD pin. Pins should be left floating or high when not in use.
  • Page 13 RM024 Hardware Integration Guide Version 3.1 is dependent on the signal strength of the received beacon, the presence and strength of interference, and randomness of the sync function. It can vary from 150 ms to over 1500 ms. GO_0/Hop_Frame The Hop Frame indicator functionality is disabled by default and controlled by the Control 1, Bit-6 EEPROM Setting.
