17.3 Setting up data logger to work with
CCFC: PakBus® variable control
The camera can receive variables, commands, or text from a data logger. The specific operational
parameters that can be altered or controlled include:
l
File Captions
l
Camera Window Defroster
l
Camera Shutdown
l
GPS Coordinates
The
SendVariables
instruction allows the data logger to transfer values or text to the camera
then use the values/text in photo or video banners. The
SendVariables
instruction can also
toggle the camera window defroster on and off and safely shut the camera down.
To update the File Caption information, declare the variable as a
String
and limit it to 255
characters (including null terminator).
The camera variable names are:
l
CCFCStillBanner1
l
CCFCStillBanner2
l
CCFCVideoBanner1
l
CCFCVideoBanner2
The variable for controlling the window defroster is numeric and needs to be declared as a Long
in CRBasic. Sending any true or non-zero value will activate both of these functions. The variable
for controlling camera power is a Boolean, which needs to be declared in CRBasic. The names of
the camera variables are:
l
CCFCDefroster
l
CCFCShutdown
Two PakBus® variables allow the data logger to send the GPS coordinates to the camera where
they are embedded in the media file metadata.
l
CCFCGPSLatitude
l
CCFCGPSLongitude
The GPS coordinates must be sent as floating point values. Positive latitude and longitude
represent northern and eastern hemispheres, respectively. While negative values represent
southern and western hemispheres, respectively. Values are not saved through a power cycle or
