1. Go to the Hardware tab in the System settings window (1).
2. Select the Video capture device object that was created before and corresponds to the configured ADC of the video capture card on the Hardware tab in the objects tree (2). The settings panel for the selected object is displayed in the right part of the Hardware tab.
   
3. If it is necessary to increase the total frame rate up to the maximum allowed value, move the Rate slider to the max position (3).
4. If it is necessary to reduce the total frame rate to the minimum allowed value, move the Rate slider to the Min min position. The minimum total frame rate of video signals, digitized and processed by a selected ADC, is 3 three times lower than the maximum allowed one.
5. If it is necessary to return the default decimation settings, move the Rate slider to the middle position. The default total frame rate is two times lower than the maximum allowed one.
6. Click the Apply button (4).
7. Close the System settings window and restart Axxon PSIM.

1. Select the Camera 1 object in the objects tree. The settings panel for the selected object is displayed.
2. Select Video capture device 3 in the Video capture device list.
3. Click the Apply button.
4. The Camera 1 object moves to the child branch of the Video capture device 3 object (see B).
5. Repeat 1-4 steps for the Camera 3 and Camera 4 objects.
6. Select the Video capture device 1 object in the objects tree.
7. Make sure that the Speed slider is in the max position.
   If the Speed slider is in the max position, then setup is completed.
   If the Speed slider is in another position, move it to the max position and do 8-10 steps.
8. Click the Apply button.
9. Close the System settings box window and restart Axxon PSIM.
10. The frame rate of the selected camera increases up to the Real time rate (for information on testing the frame rate change, see Actual frame rate).
11. If the number of connected cameras doesn't allow setting up digitization of video signal from one of the cameras with the real time rate (for example, when 15 out of 16 allowed cameras are connected) or if it is necessary to increase the frame rate of several cameras simultaneously to the rate lower than the real time one, the allocation of cameras between ADCs is performed as follows: the cameras for which it is necessary to increase the frame rate, are allocated between ADCs in the number less than the maximum allowable one. The frame rate is increased by as many times as the number of cameras on ADC is reduced.

Example 4. The ADC is configured to digitize video signal from four cameras.

f If all the cameras have a common queue, the ADC digitizes video signals in the following sequence:

...

Thus, the frame rate of Camera 1 is increased by 1.33 times and becomes equal one third of total frame rate of the considered ADC. The frame rate of Camera 2 is also increased in 1.33 times and becomes equal one third of total frame rate of the considered ADC. The frame rate of each of the remaining cameras becomes 1.5 times less and makes up 1/6 of total frame rate of the considered ADC.
