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 exposure
delay.
 Verify the exposure mode type is Synchronous, not Reset mode. (See "Synchronization Timing" on page
50).
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 Sapera
Monitor 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 may
occur with large frame color or high frame rate Genie cameras.
 Verify that network parameters are optimal as described in "CamExpert GigE Vision Parameters" on page
71. Ensure t
he host computer is not executing other network intensive tasks. Try a different Gigabit NIC or
a 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 "Exposure
C
ontrols" on page 45.
 Using CamExpert set the Genie to output its Internal Pattern Generator. This step is typically done for
any camera installation to quickly verify the Genie and its software package. See "Internal Image Test
Pattern
s" on page 68 for information on using CamExpert to select internal patterns from Genie.
Other Problems or Issues
This section describes problems that do not fit any of the categories above. Typically these are issues found in the
field under specific or unusual conditions.
Random Invalid Trigger Events
Do not change the exposure time while grabbing, else an Invalid Trigger Event may be generated. This applies to
any exposure mode or trigger source. The Invalid Trigger Event is not catastrophic and only indicates the loss of a
video frame. Stopping acquisitions first will avoid this error.
Minimum Sapera Version Required
Save User Configuration Failed: An unusual error that occurred with no other Genie control problem. The
solution is to verify the minimum Sapera version used with the Genie Framework. The Genie HM requires Sapera
version 6.20 or later. The Genie Monochrome or Color require Sapera version 6.10 or later. Sapera 7 or later is
required for any Genie installation with a computer running 64-bit Windows.
