6.8.Troubleshooting
Troubleshooting any technical issues with the CopperHead 3400 Transceiver System 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.
1. Check all your cables – 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 3200 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 your power – are the Power Supplies working?
4. If there is a power problem, check the fuses.
5. Take advantage of the various diagnostic tools provided in the CopperHead 3400 Base Station
and Camera Unit.
a. 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 strengths
lower than this – though not guaranteed to do so – 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.
b. Observe all of the LED warning and alarm lights on the Base Station and follow up based
on what you observe.
c. 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.
6. If the digital display indicates an error and displays a Hexadecimal error code you should contact
Telecast Fiber support to assist in diagnosing the problem. Note the exact error code so you can
report it to Telecast Fiber support. The hexadecimal errors indicate problems with the power
supplies and the internal boards. In general, there is not much you can do as an end user if one
of these rare error messages is displayed.
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
