Fig. 153 Input field "Timeout For Command [ms]" on the "Additional" tab
The "Timeout For Command [ms]" regulates the maximum time the application should wait for a
response from the camera to a control command. The waiting time must be entered in milliseconds.
Given the signal transmission and processing times for commands, this value should not
be set too low, otherwise communication errors can arise.
Fig. 154 Input field "Grabtimeout [ms]" on the "Additional" tab
The "Grabtimeout [ms]" input field is used to control the time in milliseconds, after which the grabbing of
an analogue video image should be aborted. The possible lower limit for this value depends on the PC
processor speed and the Framegrabber card used.
Fig. 155 Error message by grabbing a analog video image
After the unsuccessful attempt to grab a new image, the further grabbing of images will be aborted after
the specified time and an error message will be displayed. In such a case, it is recommended to check
the video connection cables and connectors. If an analogue video image can be successfully grabbed
again, it will be displayed.
Fig. 156 Input field "SleepInterval in Mainloop [ms]" on the "Additional" tab
The "SleepInterval in Mainloop [ms]" shows the pause time in the main loop of the application in
milliseconds. This time is primarily important for other applications, as with a sleep time of zero
milliseconds for example, hardly any computer capacity is available for these applications. On the other
hand, a higher value for the sleep time slows down the display speed of the analogue video image and
the reaction time of the program to keypresses.
