— 25 —SP-12000M-CXP4 / SP-12000C-CXP4Main FunctionsGPIO (Digital Input/Output Settings)The camera is equipped with GPIO (general-purpose input/output) functions for generating and usingcombinations of triggers and other necessary signals within the camera and of signals output from thecamera to the system such as those used for lighting equipment control.Valid Input/Output CombinationsThe following signals can be used as sources for each output destination (Trigger Selector, LineSelector, Pulse Generator Selector).You can also connect two different sources to NAND paths in the GPIO and reuse the signal generatedthere as a source for a different selector.The combinations of source signals and output destinations are indicated in the following.Selector(Cross pointswitch output)Source signal(Cross pointswitch input)Output destinationTrigger Selector Line SelectorPulseGeneratorSelectorAcquisition StartAcquisition EndFrame StartLine 1Line 2Line 8Line 9NAND 0NAND 1Pulse Generator 0Pulse Generator 1Pulse Generator 2Pulse Generator 3Signals to use as outputLOW HIGH Line 4 (TTL Input) Line 5 (Opto Input) Line7 (Trigger packet ) Line 10 (TTL Input2) Line 11 (LVDS Input) User Output 0 User Output 1 User Output 2 User Output 3 Software × × × × × × × × × ×Pulse Generator 0 × Pulse Generator 1 × Pulse Generator 2 × Pulse Generator 3 ×NAND 0 Out × NAND 1 Out × Exposure Active Acquisition Active Acquisition Trigger Wait Frame Trigger Wait Frame Active FVAL LVAL × × × × Trigger Source Line SourcePulseGeneratorClear SourceUse: Under the factory default settings (page 18), the external input signal from the 12-pinconnector (OPT 1 In) is connected as the source signal for the Frame Start trigger signal.
