Reset switch
Reset button functions
The reset button offers two basic functions—boot (restart) and reset (to the
factory settings)—which are called by pressing the button for different
lengths of time.
It is not always possible to install a device under lock and key. There is conse-
quently a risk that the configuration will be deleted by mistake if a co-worker
presses the reset button too long. You can define the behavior of the reset but-
ton with a setting in WEBconfig (LCOS menu tree
Setup
Config):
Reset button
This option controls the behavior of the reset button when it is pressed:
Ignore: The button is ignored.
Boot only: With a suitable setting, the behavior of the reset button can
be controlled; the button is then ignored or a press of the button
prompts a re-start only, however long it is held down.
Please observe the following notice:
The settings 'Ignore' or 'Boot only' makes it
impossible to reset the configuration to the factory settings. If the password is lost for
a device with this setting, there is no way to access the configuration! In this case the
serial communications interface can be used to upload a new firmware version to the
device—this resets the device to its factory settings, which results in the deletion of the
former configuration. Instructions on firmware uploads via the serial configuration
interface are available in the LCOS reference manual.
