122 Troubleshooting Genie Monochrome Series-GigE Vision Camera If using an external trigger, verify the trigger source rate and Genie parameters such as trigger to exposuredelay. Verify the exposure mode type is Synchronous, not Reset mode. (See "Synchronization Timing" on page50).Camera acquisition is good but frame rate is lower than expected While running CamExpert and grabbing in free-run mode at the maximum frame rate, start the SaperaMonitor tool from the Sapera Tools installed with Sapera. Make sure the Memory Overflow event monitor is enabled. Continue grabbing from the Genie at maximum frame rate. If any memory overflow events are counted,then the Genie internal buffer could not be transmitted on time and was discarded. Such a condition mayoccur with large frame color or high frame rate Genie cameras. Verify that network parameters are optimal as described in "CamExpert GigE Vision Parameters" on page71. Ensure the host computer is not executing other network intensive tasks. Try a different Gigabit NIC ora PCI Express bus version.Camera is functional, frame rate is as expected, but image is black Verify that the lens iris is open. Aim the Genie at a bright light source. Check that the programmed exposure duration is not too short or set it to maximum. See "ExposureControls" on page 45. Using CamExpert set the Genie to output its Internal Pattern Generator. This step is typically done forany camera installation to quickly verify the Genie and its software package. See "Internal Image TestPatterns" on page 68 for information on using CamExpert to select internal patterns from Genie.Other Problems or IssuesThis section describes problems that do not fit any of the categories above. Typically these are issues found in thefield under specific or unusual conditions.Random Invalid Trigger EventsDo not change the exposure time while grabbing, else an Invalid Trigger Event may be generated. This applies toany exposure mode or trigger source. The Invalid Trigger Event is not catastrophic and only indicates the loss of avideo frame. Stopping acquisitions first will avoid this error.Minimum Sapera Version RequiredSave User Configuration Failed: An unusual error that occurred with no other Genie control problem. Thesolution is to verify the minimum Sapera version used with the Genie Framework. The Genie HM requires Saperaversion 6.20 or later. The Genie Monochrome or Color require Sapera version 6.10 or later. Sapera 7 or later isrequired for any Genie installation with a computer running 64-bit Windows.
