Updating The Firmware - Northern Digital Polaris Vicra User Manual

Calibration and Firmware
Note
See the "Polaris Application Program Interface Guide" for details on checking and clearing the bump sensor, and
using the TX, BX and GET commands.
If a bump has been detected, NDI recommends that you perform an accuracy assessment procedure
with the NDI Accuracy Assessment Kit (AAK), to ensure that the Position Sensor is still calibrated.
For information on the accuracy assessment procedure and AAK, contact NDI.

Updating the Firmware

The Polaris Vicra System's firmware is stored in an EPROM flash memory device in the Position
Sensor. The latest firmware can be downloaded from the NDI Support Site at
http://support.ndigital.com.
Update the Polaris Vicra System's firmware using NDI ToolBox. (See the NDI ToolBox online help
for further information.)
The system incorporates a safe boot loader that will perform verification of the control firmware in
the Position Sensor's memory prior to loading and executing it. It has been included to provide a
fall back if a future control firmware upgrade fails. A field firmware upgrade could fail, due to
communication or power faults. In these cases, the Position Sensor will still be able to start up by
running the safe boot loader. This will provide minimal support, to allow the user to retry the
control firmware upgrade.
