15. Nikon s method short circuits the remote input to the negative line to trigger the camera The reason for this difference is the full electrical isolation to all camera inputs ws Over and above the 2 opto isolation channels used for serial communications 4 more opto isolation channels provide full isolation in both directions controlling the metering focus and fire actions of the camera as well as the monitoring of these same functions ws See the section on high speed serial remote control commands for camera remote control not using the trigger inputs 7 1 Parallel remote control connection Remote control circuitry can be added by professionals amateurs and hobbyists alike or a remote control unit can be ordered from Cocoon Creations The HarTALK is designed so that both a simple remote control using a 4 pin RJ 45 connector and a more complex full PC connection using an 8 pin RJ 45 connector can be used Shoot Shoot Focus Focus Tab under 4 pin RJ 45 for simple remote control It can be seen from the partial circuit diagram that a rather unusual connection is used and that the negative return current side of the input circuit is connected in such a fashion to allow the status of the camera focus and shoot lines to be read as well The parallel connection allows the camera to be connected to any type of electronic triggering device an example concept of which is shown below 27 ELECSPEC V1 10 X_N htto www cocoo
