CC5MPX Digital Camera
83
The defroster commands should be sent to the camera every 60 seconds or
more to ensure continuous operation.
The defroster will be allowed to turn on only once for 65 seconds at internal
temperatures between 25 and 50 °C. This flag will only be reset again once the
internal temperature drops below 25 °C, or the camera is reset. Full, continuous
operation is only allowed at temperatures of 25 °C or less. At internal
temperatures above 50 °C, the defroster will not turn on.
8.8.3.2 PakBus Control of CC5MPX Power
The ability to shut down the camera safely using a PakBus command is
available in the CC5MPX. By writing a value of 1 (or any value not equaling
zero) to the public Boolean variable
CC5MPXShutdown
, the camera initiates a
shutdown. The shutdown process can take up to 30 seconds. The camera will
turn back on after 10 minutes, or can be externally triggered.
Following is an example of the CRBasic command that will shut down a
camera with PakBus address 55:

8.8.3.3 Example Program – SendVariable Instruction
The following example illustrates the use of the SendVariable instruction to
alter Still Image Banner #2, as well as toggle the camera window defroster.
