XStream‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v5.x00 [2006.02.24]
Cyclic Scanning. Each RF transmission consists of an RF Initializer and payload. The wake-up
initializer contains initialization information and all receiving modems must wake during the
wake-up initializer portion of data transmission in order to be synchronized with the transmitting
modem and receive the data.
Figure 3.7. Correct Configuration (LH > SM)
Length of the wake‐up initializer exceeds the time interval of Cyclic Sleep. The receiver is guaranteed to detect
the wake‐up initializer and receive the accompanying payload data.
Figure 3.8. Incorrect Configuration (LH < SM)
Length of wake‐up initializer is shorter than the time interval of Cyclic Sleep. This configuration is vulnerable
to the receiver waking and missing the wake‐up initializer (and therefore also the accompanying payload data).
