WebSep 8, 2005 · It reads line after line - a line camera. I control machine's speed of line scanning rate manually and produce an H-Sync after each line. Then I connect the H-sync and the Video signals (Which are on separate lines) to an IMAQ 1410 imaging card and work in the "External H Lock Mode" in "Measurement and Automation Explorer" (MAX). The case … WebMy guess is that since pin 8 is used by digital inputs as well, you could try sending an analog vertical synchronization signal at that pin (its timing should probably match to the timing of the digital sync signals though). The other thing which needs to be watched out for is the minimum clock frequency of 25.175 MHz mandated by the DVI standard.
