Additional Options
The parameters for serial communication and the video display can be manipulated via the "Additional"
tab (see Fig. 144) .
These parameter settings should be changed with extreme caution, as possible software
malfunctions can arise. This is pointed out again in the appropriate places. If the program
no longer functions normally, the standard values shown in the separate illustrations must
be set.
Fig. 150 Input field "Number of Sending Tries" on the "Additional" tab
The number of attempts for sending a control command to the camera can be entered in the "Number of
Sending Tries" field (see Fig. 150) . This number is important, if faults in the transmission phase occur
and the camera thus does not understand the command the first time. Irrespective of the value set here,
the command is always sent at least once. The value entered is a maximum limit. If this limit is reached,
sending the command is aborted. In this case, the error message shown in the illustration below is
displayed.
Fig. 151 Error message "Communication error"
Fig. 152 Input field "Pause Between Commands [ms]" on the "Additional" tab
Using the "Pause Between Commands [ms]" field, it can be controlled how many milliseconds should
elapse between sending two commands to the camera.
As the camera only has a limited processing speed, this value should not be set too low,
otherwise it can result in buffer overflows and thus to communication errors for fast
command sequences.
