Troubleshooting
Troubleshooting any technical issues with the CopperHead 3404 Transceiver System is
similar to any piece of television production gear with the obvious exception of the core
Fiber Optic technology.
1 Check all your cablesfor any lost connections or bad connectors.
2 Confirm signal type is on the proper signal path
It is possible to physically connect analog signals to digital signal paths on the
CopperHead 3404 Transceiver System 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.
3 Check that the Power Supplies are working correctly. and check the fuses.
4 Take advantage of the various diagnostic tools provided in the CopperHead 3404 Base
Station and Camera Unit:
• Is the Fiber Optic Signal Strength within an acceptable range? The product
specification calls for strength of -22 dBm or greater, but the system will often work
at lower strengths, though this is not guaranteed
• Use the Four-character Digital Displays to check signal strength.
• Remember to check at both ends, both local and remote power. It is 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 the
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.
5 If the digital display indicates an error and displays a Hexadecimal error code you
should contact Grass Valley, a Belden Brand support to assist in diagnosing the
problem (see
Contact Us on page 81).
Take note the exact error code so you can report it to Grass Valley, a Belden Brand
support. 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: 0002 - this indicates 10 to 16 volt status may be out of range.
