When the Airborne Device Server boot successfully you will see the POST
(section 5.28) and RF_ACT LED (section 5.28) indicators light.
This push button switch restarts or reboots the Airborne Device Server module. If
pressed for more than 100ms the module will initiate an internal power-on restart
cycle. This switch is connected to pin 7 (/RESET) pin of the module; please refer
to the WLNG DP500 Data-book for more details.
The /RESET behavior is not the same as a Power-on-restart; please refer to the
WLNG DP500 Data-book for details.
This push button switch allows the user to reset the Airborne Device Server
module settings back to OEM default. The button cannot reset settings by itself; it
requires either a power cycle or restart.
To reset the module configuration back to OEM defaults SW3 must be pushed
and held while the restart or power cycle is initiated. It is required that SW3 be
held for approximately 3 seconds after the restart or power cycle has been
initiated, it can then be released. The module will then continue the boot cycle
and the OEM parameter values will be reinstalled.
