CCFC Field Camera 

A-1 

15.3  Setting Up Datalogger to Work with CCFC: PakBus 

Variable Control 

The camera is capable of receiving variables, commands, or text 

from a datalogger. The specific operational parameters that can be 

altered or controlled include: 

  File Captions 

  Camera Window Defroster 

  Camera Shutdown 

  GPS Coordinates 

The use of the Send Variable instruction allows the datalogger to 

transfer values or text that can be used in the photo or video 

banners. The Send Variable instruction is also used to toggle the 

camera window defroster on/off, or safely shut the camera down. 

To update the File Caption information with values from a 

datalogger the variable is a String and must be limited to 255 

characters (including null terminator). 

The camera variable names are: 

  CCFCStillBanner1 

  CCFCStillBanner2 

  CCFCVideoBanner1 

  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: 

  CCFCDefroster 

  CCFCShutdown 

Two PakBus variables allow the datalogger to send the GPS 

coordinates to the camera where they are embedded in the media 

file metadata. 

  CCFCGPSLatitude 

  CCFCGPSLongitude
