8 User Interface
User Interface
This chapter describes the signals generated by the cVEND operating system. In normal operation mode the
cVEND user interface is controlled by the respective application.
8.1 Boot Process
After power-on a short beep indicates that the cVEND PIN is powered and has started the boot process.
After a short time the “FEIG ELECTRONIC” logo and firmware as well as hardware version numbers are
shown on the display. A second beep and flashing of all 4 green LEDs indicates that the boot process is
finished.
Subsequent to the boot process the application will start and will show their individual messages.
8.2 Update Installation Indicators
The update installation indicators show the progress of the current update to be installed.
8.3 Security Tamper
The device contains tamper mechanisms that will trigger when a physical penetration attempt of the device is
detected. A tamper event is signalized by the cVEND PIN after power-on. Such a device has to be replaced.
Repair is only possible in the secure manufacturer environment at FEIG ELECTRONIC GmbH.
In case of a tamper event the buzzer periodically beeps with a frequency of 4 kHz for half a second every
second. On the display the message “DEVICE OUT OF SERVICE” and some additional information are
shown on a red background. The additional information that is actually issued is meant to be interpreted by
FEIG ELECTRONIC last level support only and might change with cVEND firmware releases. On both serial
ports the cVEND PIN issues periodic messages identical to the display message. Serial communication
settings are: 57.600 baud, 8 data bits, 1 stop bit, no parity bit, no flow control.
