Upgrading Sensor Firmware
SKF Wireless Machine Condition Sensor

Service Manual
When the
Overall progress
bar
indicates 100% complete, the
global firmware update is
complete.
During global firmware upgrade, the new firmware is downloaded sequentially only to
those sensors that have an older firmware version. However, if
Force upgrade
is
enabled in order to download an older version, firmware will be downloaded to all
connected sensors irrespective of their current firmware version.
This operation takes approximately 20 minutes to upgrade the firmware in each sensor,
if it is in direct contact with the gateway. This time is doubled
with each hop/router
between sensor and gateway. If at all possible, it is desirable to bring all sensors to
within one hop of the gateway to perform the upgrade to reduce the time required.
It is recommended that you let Device Manager run until it is completed. If, for any
reason, a sensor temporarily is not responding during upgrade, Device Manager skips to
the next sensor in its list. After completing the list, a new attempt to update the
firmware on skipped sensors is performed. For large systems, it is advisable to begin
the procedure before leaving at the end of the day and then inspect the results the
following day.
