It appears as though there are two versions of your camera, per the
Watec 902HS Datasheet. Which version do you have? The EIA version should output a RS-170 signal, and the CCIR version should output a CCIR signal.
After selecting RS-170 or CCIR in MAX and trying to Snap an image, does MAX error out, time out, or simply show no image? Also, is your acquisition window correct for the Watec sensor (also found in the above Datasheet - it differs for the two versions of the camera)? Finally, what Image Representation have you selected? If this is a monochrome camera, Image Representation should be Luminance (8 bits).
