6.8.Troubleshooting
Troubleshooting any technical issues with the CopperHead FS-790 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. Though it is possible to physically connect analog
signals to digital signal connectors on the CopperHead FS-790 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 you are using the PowerWafer and the camera or CopperHead Camera Unit is not powering up,
check the following:
a. The PowerWafer cable is connected to the Camera Unit’s PowerWafer jack.
b. The indicators on the Base Station are all correct (see section 4.2)
c. The fuse on the Base Station is not blown.
5. Take advantage of the various diagnostic tools provided in the CopperHead FS-790 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 Display on the Base
Station to check signal strength.
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 Systems Technical Support to assist in diagnosing the problem. Note the exact error
code so you can report it to the support technician. The hexadecimal errors indicate problems with
the power supplies and the internal boards. In general, field repair is not usually possible 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.
