4.2 C-Bus Indicator
This indicator shows the status of the C-Bus network at this unit. If sufficient
network voltage and a valid C-Bus clock signal are present then the “OK” signal
will be displayed (steady on). If a network is connected, which has more current
load than the power supplies can support, this indicator will flash to show a
marginal network voltage. If there is no C-Bus network clock present this indicator
will not light.
