1.6.2 C-BUS Timing
The relationship between bytes loaded onto the C-BUS and the transmission of FSK bytes is
shown diagrammatically in Figures 7a, 7b and 7c.
There are many ways in which the C-BUS can be used to program a device and three
suggestions (one for asynchronous FSK - Figure 7a - and two for synchronous FSK - Figures 7b
and 7c) are shown here, together with typical timings. Please note that the C-BUS timing is not
shown to the same scale as the FSK output (it has been magnified by at least 20 times to make it
visible on the same scale).
