Parameters of the parameter group "Module parameters > Frame" of the submodules
(connected readers)
This parameter group is displayed when you have selected the "Freeport" submodule. In this
parameter group, you can configure all parameters specific to the "Freeport".

Description
Parity None
Odd
Even
Fixed value 1
Fixed value 0
None Parity selection
A sequence of data bits can be expanded by a
parity bit. With its value "0" or "1", the parity bit
is added to the sum of all bits (data bits and
parity bits) to form a defined status. This in-
creases data reliability.
• None:
Data is sent without a parity bit.
• 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".
• 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".
• 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".
Data bits 7
8
8 Selection of the number of bits to which a char-
acter is mapped.
Stop bits 1
2
1 Selection of the number of stop bits that indi-
cate the end of a character.
The stop bits are appended to every transferred
character during transmission.
Interface RS422
RS232
RS422 Selection of the interface type that the connect-
ed hardware (reader / optical readers) uses.
