Brad,
What operation mode are you using with your camera? Are you using any triggers with the camera? In MAX, what mode of operation are you using?
Have you tried using a different BNC cable to connect your camera to the 1409? Check the switch array on the back of the camera to ensure that the options selected match what you have configured in MAX. Have you verified that the camera is being powered properly? If you can, try a different power supply.
