Schematic
Diagram of the NeuroCCD System Units
Connections: a. Connects the power supply to the camera. b. Control line between the camera and its PCI board. (b-f are fiber optic cables) c. Connection between the camera and the PCI board -- Channel 0. d. Connection between the camera and the PCI board -- Channel 1. e. Connection between the camera and the PCI board -- Channel 2. f. Connection between the camera and the PCI board -- Channel 3. g. Connects the 2nd A-to-D to the control panel. The BNC connectors on the front face of the control panel are connected to the inputs and the outputs of the A-to-D. h. A trigger line from the camera to the control panel. This triggers the electrical data acquisition and the experimental control of the 2nd A-to-D. The connector on the camera is labeled as "Shutter Sync". i. Fan control line that turns the camera fan off before the data acquisition to eliminate the vibrational noise caused by the fan. j. Shutter control that opens the shutter during data acquisition. k. Trigger pulse for a stimulator. l. This output provides synchronization signals to the LED and BNC8 (BNC8 is connected internally). Because the first triggering pulse from the camera does not correspond to the first frame acquired, it is important to have this synchronization signal. The pulses marked by a dashed line in the diagram below will appear on the 8th electrical trace and in the optical data when the user elect to include the synchronization test. Diagram
