Troubleshooting
Troubleshooting any technical issues with the CopperHead 3400 is similar to any piece of
television production gear with the obvious exception of the core Fiber Optic technology.
Here is a list of things to look out for and check – some of them obvious but sometimes
forgotten.
• Check all your cablesfor any lost connections or bad connectors.
• Confirm signal type is on the proper signal path.
It is possible to physically connect analog signals to digital signal paths on the
CopperHead 3400 signals will not pass through the system unless they are the correct
type. An SDI signal will not pass through the Analog or VBS paths and an Analog signal
will not pass through an SDI path. If the wrong type of signal is incorrectly connected,
the signal monitor indicator may light up because an electrical voltage is present on
the line, but no signal will pass through.
• Ensure that the Power Supplies working. If there is a power problem, check the fuses.
•
• Take advantage of the various diagnostic tools provided in the CopperHead 3400 Base
Station and Camera Unit.
• Is the Fiber Optic Signal Strength within an acceptable range? Although the
product specification calls for strength of -22 dBm or greater, the system will often
work at lower signal strengths lower,though this is not guaranteed.
• Use the four-character Digital Displays to check signal strength. Remember to
check both local and remote power. It canbe useful to know that the Base Station is
putting out good power, but the Camera Unit is not receiving it.
• Observe all of the LED warning and alarm lights on the Base Station and take
appropriate action.
• If signal strength is degraded from the time of system, checkout at a particular
location. Walk the Fiber Cable and see that it is in intact and has no damage of
severe bends or kinks.
• If the digital display indicates an error and displays a Hexadecimal error code,take note
of this error code and contact Grass Valley, a Belden Brand support to assist in
diagnosing the problem (see
Contact Us on page 83). The hexadecimal errors indicate
problems with the power supplies and the internal boards.
The Digital Display will indicate ERR and then the actual error code will display. This is a
typical error code: 00000010 – this indicates 10 to 16 volt status may be out of range.
