How Do I Create a Camera File for a Single-Tap Interlaced Parallel Digital Camera?

Hardware: Image Acquisition (IMAQ)>>Digital Image Devices

Problem:
I have a parallel digital camera that outputs odd/even fields at different periods of time on the same tap instead of outputting two taps of odd/even fields on the same pixel clock. How do I configure this interlacing mode in the Camera File Generator?

Solution:
Interlacing means different things for analog and digital cameras. The described type of interlacing is typically used with analog cameras since most digital cameras output the odd/even fields on the same pixel clock.  The Camera File Generator cannot handle this type of interlacing. However, you can copy and paste the interlacing section below into your camera file.

Area scan with frame enable connected to Enable A and line enable connected to Enable B:

Enables {
    Mode (0x2)
    HEnable (0x0)
    VEnable (0x0)
    }
Interlaced (Yes) {
    Current (Yes)
    Mode (Frame)
    Sequential (Even)
    }

Area scan with enable sections reversed:

Enables {
    Mode (0x2)
    HEnable (0x1)
    VEnable (0x1)
    }
Interlaced (Yes) {
    Current (Yes)
    Mode (Frame)
    Sequential (Even)
    }

Line scan with line enable connected to Enable A no frame enable connected to Enable B:

Enables {
    Mode (0x0)
    HEnable (0x1)
    VEnable (0x3)
    }
Interlaced (Yes) {
    Current (Yes)
    Mode (Frame)
    Sequential (Even)
    }
