Notes :

Baud rate is selectable via the appropriate system parameter. Preprogrammed factory default baud rate
is 38,400 Baud .

Bytes are transmitted least-significant bit (LSB) first using the typical serial data format of Start Bit
followed by 8 data bits followed by a Stop Bit .

The TTL Serial connection supports bit rates from 9,600 to 115,200 Baud, 8 data bits, no parity, 1 stop bit.

Host to reader interface shall be TTL level (non-inverted). Both 3.3V and 5V logic levels are allowed . See
logic levels in section Error! Reference source not found. , Error! Reference source not found. .
