Blackmagic Design URSA Mini Pro 12K (PL) - Manual (Page 190)

Below is a description of each LED color, LED action, and the status represented:
Power
Constant Red When the SMPTE hybrid fiber optic cable is connected to a powered
Blackmagic Studio Fiber Converter, and the other end of the cable
is connected to Blackmagic Camera Fiber Converter, the power LED
on the converter turns red to indicate that it is receiving power, and is
in a low power state. In this low power state, intercom functionality is
enabled but the full power required to operate the unit has not yet been
enabled.
If the power LED remains red for an extended period of time and does
not turn green, check that both ends of your SMPTE hybrid fiber optic
cable are securely connected. If the connection remains unstable,
check the condition of your fiber cable.
Constant Green After a successful fiber connection has been established and
Blackmagic Studio Fiber Converter has determined that the cable
connection is safe, the power LED will turn green and the camera
converter will enter high power mode.
Flickering between
Red and Green
If the power LED flickers between red and green, check that both ends
of your SMPTE hybrid fiber optic cable are securely connected. If the
connection remains unstable, check the condition of your fiber cable.
Tally
Constant Red The tally LED illuminates red to indicate that the camera you are
operating is currently on air.
Constant Green The tally LED illuminates green to indicate that the camera you are
operating is currently in preview mode.
Fiber
Constant Red
When the SMPTE hybrid fiber optic cable is plugged into the camera
fiber converter, the fiber LED will turn red to indicate that the handshake
process has begun, and the converter is in a low power state. In this
state, intercom functionality is enabled for use while setting up or for
troubleshooting the camera chain in case the fiber link is down.
Constant Green Once a successful SMPTE hybrid fiber optic cable connection is
established, the fiber LED will turn green.
Once both the power and fiber lights are green, this indicates that the safety checks have been
completed, and the converters have entered high power mode.
Audio Inputs
Your Blackmagic Camera Fiber Converter has two XLR inputs labelled ‘1’ and ‘2’ that allow you
to plug in external analog audio from professional equipment such as audio mixers, PA systems
or external microphones.
