By default, data is transmitted at 9600, n, 8, 1, no handshaking. Two protocol modes<br />
are supported. The protocol mode is configured in the reader EEPROM. As factory<br />
default, the ASCII protocol is used.<br />
12.1 ASCII Protocol<br />
This protocol is designed for easy handling. The commands are issued using a<br />
terminal program. Data is transmitted as ASCII hexadecimal that can be displayed on<br />
any terminal program (i.e. HyperTerminal).<br />

12.2 Binary Protocol<br />
Figure 12-1: ASCII protocol frame<br />
This protocol is designed for industrial applications with synchronization and frame<br />
checking. An addressing byte for party line (master/slave, multi-drop) is also<br />
included.<br />
The protocol usually requires a device driver. Data is transmitted in binary mode. The<br />
reader uses an internal binary watchdog timer to ensure correct framing.<br />

The binary frame version 2 is only sent to the host. It is implemented to give<br />
extended information to the host.<br />
Version 2 must be enabled in the Protocol configuration 2 register.<br />
