5.2 SERVICE FIRMWARE
Service firmware is the most important part of the reader firmware. Right after power-up it will check the
emergency button if any action is required. Then it will check the normal firmware for integrity. If the normal
firmware is not valid then the emergency firmware will connect to server in emergency mode and download
the firmware. If the normal firmware integrity is ok, then it is started.
5.3 READER FIRMWARE
Ethernet Reader firmware is the main part of the firmware. It initializes network, autodetects readers and
sends the card number to the server when card is placed. By default the firmware starts UDP locator server
which will help detecting available readers on the local network. Also the TCP configuration server is started.
