offset the capture times of the photos so that only one camera is
attempting to transmit a file at any given time.
The camera can download photos or video via an RS-485 port
using the PakBus protocol. An MD485 is required to interface the
camera to a datalogger. The following items are required for RS-
485 PakBus communications and can be confirmed by either the
web interface of the Device Configuration Utility:
Confirm that the PakBus port parameter of the
Communications Setting is reading RS-485.
Set the RS-485 BAUD rate to match the BAUD rate of the
device being connected to the camera.
Set the parameter PakBus Address of Communication
Settings to a unique value in the PakBus network.
Set the parameter PakBus Destination Address of the
device that the camera needs to send photos to.
Include PakBus Security Code, as required.
15. Send Via PakBus: PakBus Communications
The CCFC camera uses the PakBus protocol to send photo or
video files from the camera to a Campbell Scientific datalogger or
other PakBus compatible devices. The LoggerNet Tool PakBus
Graph can be used to change the configuration of a camera. The
use of the PakBus Graph is discussed in Section 15.2 Send Via
PakBus: PakBus Graph Operations. Refer to the LoggerNet
literature or software for more details.
PakBus can also be used to control specific operational
parameters and to transfer variables or text between the
datalogger and camera. When a photo or video file is ready to be
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
