7.3 Reset Message
A reset of the reader occurs automatically whenever the reader is being powered up. A reset can also be
actuated through the RS-232/USB interface.
In either case the reader transmits one time a Reset Message, which has the same structure as the normal
response to a command and the following contents:
byte 1 2 3 4 5 6

BAUD Indicates the hardware baud rate setting (default baud rate), which is set to 9600 bps (this is
only valid in the RS232 reader).
The reader does not expect an acknowledge signal from the computer. After transmitting the Reset
Message the reader is waiting for the first command from the computer.
7.4 Card Status Message
When a card is being inserted into the reader or an inserted card is being removed from the reader while the
reader is idle, i.e., not executing a command, the reader transmits a Card Status Message to notify the host
computer of the change in the card insertion status.
In a system where these unsolicited messages from the reader to the computer are not desired, they can be
disabled with the SET_NOTIFICATION command. Please note that the setting made with this command is
volatile and will be lost with the next reader reset or power up. By default, the Card Status Message will be
transmitted by the reader after a reset.
The Card Status Messages have the following structure and contents:
