Use this command to select the video source settings for a BitFlow interface board (Raven, Road Runner, R3, R64). If you choose this command, the Video Settings dialog box will appear. Click the Video Source tab, and you will see the following options:

Displays the family (product line) of BitFlow boards selected for the video capture. If boards of different families are installed on your system, use this option to select the active family. Currently supported product lines are Raven, Road Runner / R3, and R64.  
Displays the model of the currently selected BitFlow board and the board's number. Boards of the selected Family are numbered sequentially as they are found when the system boots. A given board will be the same number every time the system boots, as long as the quantity of boards remains the same and they remain in the same PCI slots. A typical selection in the Board field will read as follows:  
#1 R64-PCI-CL  
which indicates that the first R64 board is currently selected for the video capture. If you have more than one board installed on your system, you can switch to another board of the same family (in the above example, another R64) by choosing the corresponding board in the list.  
Lets you choose a camera connected to the current Board. By default, ImageWarp will use the first camera in the list maintained by the SysReg application from BitFlow SDK. The name of the corresponding camera configuration file will appear in the Camera box. You can change the current camera by selecting the desired camera configuration file from the list, which will display all camera files available for the current Board. The camera file list comes from folder defined in SysReg application as the Camera configuration file path. See BitFlow SDK User Guide for more details.  
Lets you choose one of the four analog video inputs when you use multiple cameras connected to the Raven board. If the currently selected Board is of a different type, this option will be disabled.  
External Trigger
Lets you connect the external hardware trigger to the acquisition circuitry. If you do not have a hardware trigger and want to use the software trigger, clear this option to disable the trigger circuitry. If this option is checked and no trigger is connected, the board may randomly self-trigger from the electric noise on the unconnected input.  

Click this button to return the options for the currently selected Board to their default state. The camera configuration will change to the one selected in the SysReg application and the Video Format and Video Display settings will be restored according to the ones in the camera file.  
Note – ImageWarp remembers the video options you have selected for each board. When you switch to another board, it will be associated with the camera file and the format/display settings you used in your last session. To reset the camera file to its default parameters, select it from the Camera list again. To reset the board to its default parameters, click Defaults.
