19.2 kBd Selection depends on the Ident
device/system being used. With
57.6 kBd
this parameter, you set the data
115.2 kBd
transmission speed between the
921.6 kBd communication module and the
reader.
-- Details on this parameter are pro-
vided in the table below.
Meaning Description
None Parity selection
A sequence of data bits can be

expanded by a parity bit. With its
Odd
value "0" or "1", the parity bit is

added to the sum of all bits (data
bits and parity bits) to form a de-

fined status. This increases data

None:
Data is sent without a parity bit.
Even:
The parity bit is set so that the
sum of the data bits (including
the parity bit) is even when the
signal state is "1".
Odd:
The parity bit is set so that the
sum of the data bits (including
the parity bit) is odd when the
signal state is "1".
Fixed value 1:
The parity bit is set permanently
to the value "1".
Fixed value 0:
The parity bit is set permanently
to the value "0".
