About Operating Modes
During operation, DynaFlex devices transition between distinct operating modes, which are important for
operators to understand so they can properly control the device:
Powered Off Mode
is the shipping and storage mode of the device. Operators would not generally
use this mode during a work shift or during off-shift recharging. It occurs when the operator holds
the pushbutton for more than 8 seconds (or more than 12 seconds to force immediate power off
without a proper shutdown sequence), or if the device’s battery is critically low and the device is not
connected to a USB power source. In this mode, the device consumes practically no power. To move
the device from Powered Off mode to Active mode, press the pushbutton for one second with the
battery charged, or connect the device to USB power. If the device is already connected to USB
power when it enters Powered Off mode, it automatically powers back on.
Reset Mode
is a transient mode where the device first transitions to Powered Off mode, then
automatically powers back on. It occurs when the operator presses the recessed switch, or the host
sends the Reset Device command, or the device automatically performs a daily security reset.
USB Suspend Mode
occurs when the USB host that is providing power to the device sends a
USB
Suspend
control event to the device to conserve power. The device responds by powering off nearly
all of its modules, including the display, and listening for the USB host to send a
USB Resume
control event. To move the device from USB Suspend Mode to Active Mode, the host software must
open a USB connection to communicate with the device, which signals the operating system that the
device is in active use and should be allowed to draw full power from the USB port. It is not
necessary for the host software to send commands to the device at that time.
Active Mode
is the device’s normal “awake” state when it is in use. In this mode, the touchscreen
display and LEDs are powered on and the device is ready to receive commands from the host. This
mode can be divided into substates like Active/Host Not Connected, Active/Host Connected,
Active/Host Communicating, Active/Armed for Read, Active/Reading, and so on. These substates
differ in the amount of power they consume, and are mostly under the control of the host software.
To move the device from Active mode to Powered Off mode, press and hold the pushbutton for 8
seconds. If the device does not respond, continue holding the pushbutton for longer than 12 seconds
to force immediate power off without a proper shutdown sequence. To move the device from Active
mode to Reset Mode, press the recessed switch.
