NOTE: for 12-bit and 10-bit acquisition, it is very important that the GROUND of the camera be connected to the POWER SUPPLY GROUND, which in turn must be connected to the GROUND of the Pulsar.

Special Considerations
Continuous mode
The main cable can be used without modification for both 12-bit and 10-bit acquisition;
however, the adapter cable must be modified for 10-bit acquisition
When high, the FVAL (vsync) signal indicates that a valid frame is being output; a high
LVAL (hsync) signal indicates that a valid line is being output. The falling edge of the STROBE (pixel clock) signal indicates that a valid pixel is being output. The first falling edge of STROBE after LVAL goes high with FVAL high marks the first valid pixel of data
The DCFs can be modified for asynchronous reset and exposure control; contact Matrox
