20.9.3 Using the standby mode

20.9.3.1 System requirements

• "Firmware version" at least "1.6.188.0"

• "mvIMPACT Acquire driver version" at least "2.10.1"

Using mvDeviceStandbyTimeout:

• "Firmware version" at least "2.12.406.0"

• "mvIMPACT Acquire driver version" at least "2.17.1"

20.9.3.2 Introduction

It is possible to switch the mvBlueFOX3 into a power down mode (standby) either

• by changing the property "mvDevicePowerMode" to "mvStandby" or

• by enabling the automatic power down mode by setting the property "mvDeviceStandbyTimeoutEnable" to

"bTrue" and by specifying the timeout using the property "mvDeviceStandbyTimeout".

The latter one will switch the camera to the power down mode as soon as no register was read (i.e. neither the

camera is used nor images were acquired) during a speciﬁed time period (in seconds) speciﬁed by the property

"mvDeviceStandbyTimeout".

Note

As soon as the device stays open by an active driver instance, the driver will periodically read small chunks

of data from the device to keep it open when auto standby is active. However if the application terminates or

crashes the device will automatically move into standby mode after the speciﬁed timeout has elapsed.

The power down mode has following characteristics:

• The power consumption drops to 70 mA and

• the LED turns red.

If you change state again to power on, it will take about 7 seconds for the camera to wake up. During the wake up,

all user settings will to be restored, except for the LUTs. Afterwards, the LED will turn green again.
