Accessory terminal pinout
Hi, does anyone have the accessory terminal pinout mapped for the D90. It looks like there is a 5-12V pin for focus and shutter release. I'm trying to build a trigger to release the shutter on sound and light. I have the optic and acoustic transducers with preamps to get me about 6V, but I didn't want to start playing around on the camera's interface blindly. Thanks.
