6.2 Troubleshooting Using the Serial Interface
The following commands can aid in debugging. (The complete command protocol is
described in Appendix B.)
Communications
To quickly verify serial communications send the help command. The h command
returns the online help menu.
Verify Parameters
To verify the camera setup, send the gcp command.
Verify Factory Calibrated Settings
To restore the camera’s factory settings, send the rfs command.
After executing this command send the gcp command to verify the factory settings.
Verify Timing and Digital Video Path
Use the test pattern feature to verify the proper timing and connections between the
camera and the frame grabber and verify the proper output along the digital processing
chain. See below.
Generating Test Patterns
The camera can generate a test pattern to aid in system debugging. Use the command
svm i to activate the test pattern (see section 3.14 Setting the Video Mode and
Generating Test Patterns for details). The test pattern is a ramp from 1 to the number of
pixels in the line, then starts at 1 again. Use the test pattern to verify the proper timing
and connections between the camera and the frame grabber.
No test pattern or bad test pattern — May indicate a problem with the camera (e.g.
missing bit) or a system setup problem (e.g. frame grabber or timing). Verify the
presence of the LVAL and STROBE signals.
Test pattern successful — Run the svm 0 command to deactivate video correction.
Verify Temperature
To check the cam era’s internal temperatu re, u se the vt command. If it is within the
proper range, the camera returns OK>. Otherwise the camera returns an error message.
LED Status
Located on the back of the camera is a red/ green LED used to display the operational
status of the camera. Red lights indicate errors or warnings and green lights indicate
progress and OKs. Error and warning states are accompanied by corresponding messages
further describing current camera status. See section 2.2.1 LED Status Indicator for the
complete LED information.
