mode set to Full Power Save will allow the camera to respond almost
immediately (less than 10 seconds).
The external trigger can also be utilized to wake up the camera and enter high
powered mode. As long as the external trigger is held high, the camera will
remain in the high powered mode. Lowering the external trigger signal will
allow the camera to enter a low powered operating mode again.
8.8.3 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:
• Still Image Banners
•
Video Banners
• Camera Window Defroster
•
Camera Shutdown
The use of the Send Variable instruction allows the datalogger to transfer
values or text that can be used in the image or video banners. The Send
Variable instruction is used to toggle the camera window defroster on/off or to
safely shut the camera down.
To update the Banner 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:
• CC5MPXStillBanner1
•
CC5MPXStillBanner2
• CC5MPXVideoBanner1
•
CC5MPXVideoBanner2
The variable for controlling the window defroster is numeric and needs to be
declared as a Long in CRBasic. The variable for controlling camera power is a
Boolean, which needs to be declared in CRBasic. The names of the camera
variables are:
•
CC5MPXDefroster
• CC5MPXShutdown
8.8.3.1 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 page or DevConfig , or PakBus SendVariables command.
To turn on the defroster, the numeric value should be set to a non-zero value
(i.e., 1). To turn the defroster off, the value should be set to zero. 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 to zero
and will begin the countdown again.
