Genie Monochrome Series-GigE Vision Camera Operational Reference • 45External Trigger Level-controlled Exposure• Also known as “Pulse Width Control” exposure. See the timing diagram below.• The external trigger edge initiates the exposure process. The active external trigger edge can be selected aseither the low-high or high-low transition.• No delay from active trigger edge to start of exposure.• Exposure is stopped by the opposite edge on the trigger signal. Therefore the exposure time is defined by thetrigger pulse duration.• Supports "Reset Mode" on page 47 trigger timing only.External Trigger Level-controlled Exposure TimingExposure Controls via Sapera LT or GenICam ApplicationsSaperaGenie Sapera parameters for Exposure Control:FrameRate = 0.1 Hz up to max. frame rate supported by sensor in current mode of operation.Only available with Trigger disabled.ExposureMode = {Programmable = 1, Pulse Controlled = 2}ExposureTime = Exposure duration in μsIn CamExpert, these parameters are available under “Sensor” tab.See "Accessing Features with Sapera++ LT" on page 68.GenICam features for Exposure Control:ExposureMode = {Off = 0, Timed = 1, TriggerWidth = 2, TriggerControlled = 3,ResetContinuous = 4}ExposureTimeRaw = Exposure duration in μsAcquisitionFrameRate = Controls the desired frame rate of the camera in mHz (0.001 Hz).
