CCFC Field Camera
78
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:
x
CCFCStillBanner1
x
CCFCStillBanner2
x
CCFCVideoBanner1
x
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:
x
CCFCDefroster
x
CCFCShutdown
Two PakBus variables allow the datalogger to send the GPS coordinates to the
camera where they are embedded in the media file metadata.
x
CCFCGPSLatitude
x
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 in
Off Mode , but do need to be
updated every time a photo is sent. When using PakBus variables for GPS,
coordinates must be entered in decimal coordinates.
15.3.1 PakBus Control of Window Defroster Function
PakBus will temporarily (one shot) override the existing window defroster
control state. Users are advised to only use one type of control to avoid
unexpected operation of the defroster. Options include the
Automatic Mode set
via the web interface, Device Configuration Utility , or the PakBus Send
Variables command.
To turn on the defroster, the numeric value should be set to a non-zero value
(i.e. 1). When a non-zero value is sent to the camera, the heater will turn on and
a 65 second countdown timer will start. After 65 seconds, the defroster will
automatically turn off (this should override settings already in place). If an
additional non-zero is sent before the defroster is turned off, then the timer will
be reset and will begin the countdown again from 65. Sending a zero value
using this variable will not turn off the defroster regardless of which method
was used to turn it on.
