Appendix D. Setting Up RF401-to-CR206(X) Communications

FIGURE D-2. This graph represents a transmitting radio that uses a

long header and a receiving radio that is in a sleep cycle. The

length of the wake-up initializer exceeds the time interval of cyclic

sleep ensuring that the receiver detects the wake-up initializer and

receives the payload (i.e., transmitted data).

FIGURE D-3. This graph represents a radio that transmits a wake-up

initializer that is shorter than the cyclic sleep of the receiving radio.

The receiver does not detect the wake-up initializer and remains

asleep—missing the data transmission.

1. Any radio that is transmitting to a sleeping radio must have a

long header that spans the sleep duty cycle.

NOTES

2. When a CR206(X) (or RF401) transmits to another CR206(X)

(or RF401), the receiving radio knows when the originally

transmitting radio is awake and not duty cycling. This allows the

radio to only transmit a long header when it is needed.
