15.4 PakBus Neighbouring Address
The PakBus protocol allows devices to relay data in a network.
The CCFC has the ability to communicate with devices that are
several hops away on the PakBus network. To configure this new
feature, a setting has been added to the PakBus configuration
screen on the web page.
Physically entering the address of the PakBus device connected to
the CCFC PakBus communication lines allows the neighbor to
relay communication between the CCFC and the final destination
for data. Leave PakBus set to zero (0) if the CCFC is directly
connected to the final destination.
16. Power Calculations and Timings
The CCFC was specifically designed for operation in power-
constrained systems such as solar powered sites. It is critical in
such systems that the camera be properly configured to meet the
constraints of the intended application. This section outlines the
power consumption of the camera for purposes of power supply
design for a system.
16.1 Standalone Operation
In standalone mode, the camera operates as a self-contained photo
and video recorder. Files will be stored onto the internal camera
memory.
The current draw of the camera is mainly dictated by the
quiescent current draw of the Power Mode, plus the current draw
when the camera enters the Fully On power mode (Active Current
Draw) to acquire a photo or video. Table 16-1 shows some total
power consumption (standalone) figures in Amp-Hours per day
depending on the Power Mode and frequency of photos.
One thing to note is that the Off State will only consume less
power than the Deep Sleep state if fewer than 24 pictures are
taken per day. This is due to the boot-up time that the camera
requires when exiting the Off State. The extra boot-up time means
that the camera consumes the Active Current for a longer time
(120 seconds).
