6.5 Initialization Self-Test Function
In addition to internal fault monitoring, the SE4000 microcontroller performs built-in-self-tests
(BIST) automatically during the initialization process. If a failure is detected, the LCD displays an
error message to alert the user to the problem. The error messages are displayed in the same
format as faults.
If the SE4000 did not display an error message during initialization, but is not operating properly,
perform the following diagnostic steps.
1.
Verify that the SE4000 is configured correctly for your requirements.
2.
If your system is configured properly, but still not operating correctly, issue the front panel
QuickSet>DVB>Enter
command or the
CM RESTORE DVB
remote command to reset
the SE4000 to the defaults.
3.
Reset any site specific custom configuration parameters.
4.
If the SE4000 is still not operating properly, query the current faults to determine if a
current fault exists. Correct all current faults.
5.
Query and review the fault history log. Correct all faults, if possible.
6.
Record the fault history.
If your SE4000 continues to fail, contact the Radyne ComStream Customer Support Department
for assistance.
