transmitted, the camera will initiate communications and send the
photo or video via the selected serial interface.
The CCFC is capable of producing video files that exceed 30MB.
Trying to send such a large file to a datalogger using PakBus can
be problematic. For this reason, the CCFC is setup to not send
any files using PakBus that are larger than 2MB.
The camera is a PakBus Leaf node and is not capable of
performing any routing. However, the CCFC has the ability to
communicate with devices that are several hops away on the
PakBus network.
15.1 Send Via PakBus: Concurrent PakBus Communications
PakBus allows the camera to download photos to a datalogger
simultaneously with other datalogger communications. A
communications task will take longer if the datalogger is
communicating with multiple devices at the same time.
It is beneficial to set the system timing up to avoid photo transfers
when other communications are scheduled.
For example, longer connect times on long distance telephone
connections can be avoided by scheduling photo transfers from
the camera to the datalogger outside the scheduled data collection
time. If a station is called on the hour to retrieve data, photo
acquisitions could be initiated before the scheduled call (15
minutes prior) to shorten the connect times.
15.2 Send Via PakBus: PakBus Graph Operations
The CCFC supports configuration via PakBus Graph over the
serial port. A datalogger or other type of PakBus relay device is
required to interface PakBus Graph to the camera.
15.2.1 Datalogger Settings
The datalogger must be configured as a router (i.e. Is Router must
be set to true) and the camera PakBus address must be in the list
of allowed neighbours for the datalogger port used. The camera
and the datalogger must be set to use the same baud rate to
communicate properly.
15.2.2 Discovery
After starting the PakBus graph, the camera may not be visible
immediately. To discover the camera, right click on the green box
marked as
[4094] in the graph and click on Search for
Neighbours . This will open the Search for Neighbours dialog
box, press the Start button and the graph should display all the
devices within the PakBus network.
