Troubleshooting
As a troubleshooting aid, the reference signal status and presence, power and CPU status can be easily
monitored from the front panel of this module using the front panel indicators.
Refer to the overall troubleshooting tips given below for Models 7400 and 9400:
No Generator A or Generator B LED indication
• Generator is not locked to its timing source. At least one of the Generator A
or Generator B LEDs should be lit to indicate the primary output line standard
and that it is locked to its timing source. Check source settings in the Global,
SPG A and SPG B menus.
Cannot control module
• Check status of CPU Run green LED. Should be blinking slowly and in unison
with other modules if System Control module is present. If not, try removing
the 7400 or 9400 module and plugging it in again to be sure it is seated
properly.
• System module may not be working properly if installed.
Module controls are grayed out
• Module is locked or access to module controls is restricted by the User Level
which is set in Avenue PC.
No signal out of module
• Check status of Ref green LEDs. One should be lit to indicate which reference
rate is currently being detected. If not, check the reference input or master
frame signal for presence and quality.
• Check cabling to input of module.
