2.1.6 Power Supply and AS-i Connection Method
AS-Interface Masters/Gateways
The AS-i master does not require a separate power supply. The communications power of
the AS-i master is supplied in full from the Inline Modular local bus. All the power for the ASi
electronics is obtained directly from the AS-i network (current consumption around 200 mA
from AS-i). An additional 24 V power supply is not required for the AS-i master. The AS-i
master is simply integrated in the Inline Modular local bus and connected to the AS-i cable.
The master starts working when the AS-i power supply unit is switched on.
Like all other AS-i components, the AS-i power supply unit is connected at any point in the
AS-i network via the AS-i cable, see also "Power Supply Units" on page 3-1.
