repeatedly update its firmware every time the camera wakes up from its quiescent
mode.
4. Communications
4.1 PakBus Communications
The camera uses the PakBus protocol to send image files from the camera to the
datalogger or other PakBus compatible devices.
Communications are not enabled while the camera is in its quiescent mode. This is
done to conserve power in its low power state. When an image file is ready to be
transmitted, the camera will initiate communications and send the JPEG image via
the selected PakBus port.
The camera is a PakBus Leaf node and is not capable of performing any routing.

4.2 RS-232 Port
The 10-pin RS-232 header connector is designed to provide a 9 Pin DCE type port
by using either of the ribbon cable adapters provided with the camera. Part number
C1946 provides a male 9-pin connector and C1947 provides a female 9-pin
connector.
The RS-232 port can also provide an additional communication port for
transmitting image files to a datalogger using the PakBus Protocol. Figure 3
illustrates the required connection to a RS-232 port on a Datalogger. A Datalogger
and camera are both DCE type RS-232 devices; thus, requiring a NULL modem
cable.
