Basic operation
This section covers basic operation of the device such as start-up, shut-down, suspend, resume, display
operation and status notification.
Observe that the behaviour of various on/off controls (external
on/off control and front panel soft
keys) is user configurable in terms of:
Enabling/disabling functionality
Which push button that shall hold the on/off functionality.
Configurable timing parameters
Button backlight is used for status notification while starting up, shutting down or when de device is in
suspend mode. Both button backlight and the buzzer is software controllable for notifications from
user applications.
See
chapter 4.5
for details of button backlight status notification.
The buzzer is also used for various error notifications, see
chapter 4.6
for error code details.
4.1.
Turning ON/OFF
The device can be configured to turn ON or OFF from one or more of the actions described in the
following chapters. Not all on/off triggers are enabled by default but all software configurable.
To ensure that data does not get lost or the flash memory becomes corrupt, it is recommended that
necessary data is saved and user application properly closed before the device is shut down.
Note that the shutdown triggers described herein don’t have affect if the device has entered Suspend
mode. The device must either first be
resumed
or reach its
suspend time-out
to be able to shut down.
See
chapter 4.2
for suspend/resume details.
4.1.1.
External ON/OFF signal
Turn ON the device by pulling the signal high (above 5.0 V), preferably by connecting to the positive
supply voltage through a turnkey switch according to the application example (see
chapter 3.2.4
).
This start-up action is enabled by default but may be disabled by user application.
Turn OFF the device by disconnecting or pulling the signal low (below 1.0 V) for at least 4 seconds
(default response time) , i.e. using the turnkey switch. See
chapter 3.2.4
for
application example.
The external on/off signal is configured as
shut-down trigger
by default but may be
disabled
(or changed to
suspend trigger
) by software. The response time defaults to 4 seconds but is
user configurable.
Note that the device won’t restart automatically if the external on/off signal is brought high
while the device is in the progress of shutting down (shutdown may take several seconds). A
low-to-high transition must occur after the shutdown is fully completed to trigger a restart.
Increase the shutdown trigger response time in case you don’t want the
CCpilot VA
device to
shut down during short stops.
