Operation
Operation of the CopperHead 3430AP Transceiver System
3 To avoid the possibility of damaging the Camera or Camera Remote Control Panel turn both
the Camera Unit and the Base Station off before disconnecting the Control Cable from the
Control Panel, the Base Station, the Camera Unit or the Camera itself.
4 Protect all cables from dirt, water entry and being dragged across the ground or other sur-
face.
5 When re‐spooling the cable take your time so as to avoid cable snags, crimps or damage to
the connectors. Re‐spool evenly across the reel.
6 If the Base Station is a permanent or semi‐permanent installation, then simply power off and
disconnect and cap the fiber cable.
Troubleshooting
Troubleshooting any technical issues with the CopperHead 3430AP 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 Sta-
tion and CopperHead 3430AP 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 Dis-
plays 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 Cam-
era 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 Grass Valley support to assist in diagnosing the problem. Note the exact error
code so you can report it to Grass Valley 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: 0002 – this indicates 10 to 16 volt status may be out of range.
