Operating states

The AWR300 has several operating states concerning display status and communication
possibilities over USB. The following chart shows the different states.
Stickreader Mode (CDC)
Virtual Comport
Communication enabled
Switch-Off-Time
Suspend Mode
Display OFF
Communication enabled
Key pressed
When the reader is switched on and it is connected via USB, it works in CDC mode. That means
a virtual comport is created on the computer and it is possible to send commands to the device
via a serial port connection. In this state the mass storage mode is not activated, it is not possible
to copy files to or from the AWR300.
After the configurable switch-off-time (default = 60 seconds) has elapsed, the reader enters
suspend mode. The display is switched off but communication is still possible. In this state the
blue LED on the right above the display is flashing in cycles of one second. After the switch-off-
time has elapsed again, the device enters sleep mode and communication is not possible
anymore. When the external power adapter is connected (charging, multicolor LED is flashing
red), the device will stay in suspend mode and will not enter sleep mode at all.
If the AWR300 is connected to USB while it is switched off, the SD-card mode is activated. Then
the reader is attached to the computer as a mass storage device and file transfer is possible.
Once the key is pressed, the device will switch on and use CDC mode right away.
