Troubleshooting
Troubleshooting any technical issues with the CopperHead Prois similar to any piece of
television production gear with the obvious exception of the core Fiber Optic technology.
Keep the following tips in mind:
• Check the LINK indicators at each end of the system. They should be illuminated Green
if there is good fiber optic connectivity for the non-SDI signals (VBS/sync, camera
control, intercom, tally).
• Check the SDI indicator at the CopperHead Pro Base Station. It should be illuminated
Green if there is good fiber optic connectivity for the SDI signal.
• If the LINK or SDI indicators are not Green, there maybe low optical power between
Camera Unit and Base Station. Thefollowing are possible solutions:
• Ensure that all fiber optic connectors are clean. Clean fiber optic connectors are a
requirement for reliable connectivity between fiber optic components like your
CopperHead transceivers. Any contamination in the fiber connection, even
microscopic dust particles, can cause "link loss" and adversely affect the
operational functionality of your CopperHead equipment. For more information
on the care and maintenance of your fiber optic connectors, refer to
• Examine the entire length of the fiber cable and see that it is in intact and has no
damage or severe bends or kinks.
• Confirm that all fiber optic connectors are connected securely.
• If optical power is good, but signals are not being received:
• Check all of your copper cables (coax) and connectors (BNC) for damage.
• Confirm signal type is on the proper signal path - It is possible to physically connect
analog signals to digital signal paths on the CopperHead Pro.
However, 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 LED indicator may illuminate, but no signal will pass through.
• Base Station power problems:
• 12VDC Base Station: Check that the DC power supply is functioning correctly and
connected securely.
• 110/220 VAC Base Station: Check the fuses. Do not try to multiplex the
CopperHead Pro with other fiber optic devices. The CopperHead Pro system is not
readily compatible with any active or passive CWDM technologies, including
TelePort and TeleThon systems.
