This camera CD 3730 DC is a Double speed 50/100 fps progressive scan camera, it have several functional modes, one of then is interlaced or not interlaced mode. I configured it the all forms possible but I have not good luck. I read NI 1409 data sheet, and this framegrabber can work in different forms with different interfaces, I set it but I haven�t good luck. If any can help me, I will appreciate it.
