Power Safety Considerations
The SMPTE hybrid fiber optic cable is capable of carrying high voltage over long
distances so that you can power a camera and accessories that are located up
to 2km away.
To ensure safe operation, your Blackmagic Studio Fiber Converter has safety
mechanisms built in to ensure accurate monitoring and automatic management of the
voltage being carried.
A dedicated micro controller along with internal handshaking and communication
between the Blackmagic fiber converters ensure that a hybrid fiber optic cable
remains off until it is plugged into the Camera Fiber Converter. It then goes into a low
power state and completes safety checks before going into high power mode. High
voltages are not enabled until the converters ensure that an optical signal is present,
there is a 5mA signal core current loop, and there is less than 30mA of imbalance
between the power cores.
Connecting to an ATEM Switcher
How to connect Blackmagic Studio Fiber Converter to your switcher:
1
Connect a BNC cable from Blackmagic Studio Fiber Converter's rear 12G-SDI output
to one of the SDI inputs on your switcher. Ensure your camera is set to use the same
format and frame rate as your switcher.
2
Connect a BNC cable from your program return feed output on your switcher to the
'return in' 1 input on the studio unit's rear panel.
TIP
When using multiple cameras in a live production, you may need to run
the program return feed from the switcher through a Teranex Mini SDI
Distribution 12G or a Smart Videohub. That is because there are a set number
of program outputs on the switcher and you will likely need access to more.
3
If you require any other return feeds to be sent to your camera such as a clean program
return feed, a teleprompter feed, an ISO feed from another camera, graphics or any
other signal then plug these into 'return in' 2 or 3.
Plug the program return feed from the switcher and other return sources
into the 'return' inputs on the studio unit's rear panel
