    Hardware trigger for depth images


      Hello, does anyone know if the realsense cameras have any external hardware triggering capabilities for depth frame capture? We are trying to sync depth data measurements with other data sensors running on a different device/clock, and we need really high (sub-millisecond) precision alignment between the two data sources. We could try triggering from software, but the OS would add some delay, and we would lose sub-millisecond precision. Alternatively if there was some sync pulse that the board can output whenever a frame is taken, we can use that for data alignment as well. The datasheet for the ZR300 indicates there is some Trigger (from Depth Camera) for the fish-eye camera, but I'm not sure what the "from depth camera" means. Would someone be able to clarify whether we can use this trigger for depth frame collection as well as the fish-eye?
