Polaris Vicra System Overview
Front View
The front of the Position Sensor incorporates the following components:
Illuminator Two arrays of infrared Light Emitting Diodes (IREDs) that provide IR light for the
passive sphere markers or a "chirp" activation trigger for active markers.
Sensor Two sensors that each comprise a lens and CCD. They collect IR light that is reflected from
passive sphere markers (passive mode) or emitted from active markers (active wireless mode).
Indicator LED Three LEDs that provide the following indications (left to right):
•
Power LED :
Flashes green during system warm-up.
Steady green when system is ready for use.
•
Status LED
Steady green when the communications connection is available.
•
Error LED
Lights steady amber if a critical error is detected (Position Sensor must be returned to NDI).
Flashes amber if a non-critical error is detected (for example, a firmware update is not
completed).
Note
If a non-critical error is detected (error LED is flashing), refer to the NDI ToolBox application to further diagnose
the fault. (The nature of the error is described on the NDI ToolBox initial page.) If you are using your own
applications, use the GET command to read the "Info.StatusAlert" parameter to check the alert status. Refer to
the "Polaris Application Program Interface Guide" for further information.
