5. On A310f cameras exposure of a new image can begin while the previous image is being read out This is commonly referred to as overlap mode Following the recom mended method for exposure start in Section 3 2 6 will allow you to overlap exposure with readout and achieve the camera s maximum frame rate For more information about overlap mode see Section 3 2 8 BASLER A310f Basic Operation amp Standard Features 3 2 4 Controlling Exposure Start with a Software Trigger Exposure start can be controlled by sending a software trigger command to the camera via the 1394 bus The Trigger Mode control register see page 4 25 is used to enable the ability to start image exposure with a software trigger The Software Trigger control register see page 4 20 is used to set the software trigger If you are triggering the camera with a software trigger only the programmable exposure mode is available In programmable mode exposure starts when the Trigger field in the Software Trigger control register is set to 1 The length of the exposure is determined by the shutter settings described in Section 3 2 1 Note that the Trigger field in the Software Trigger control register will self clear to 0 when it is safe to begin each new exposure Figure 3 3 illustrates programmable exposure with a software trigger Software Trigger register self clears lt gt Exposure determined by shutter settings S
