messages 
Hard errors 
With this parameter, you set whether hardware 
diagnostic messages will be reported. 
•  None: 
Apart from standard diagnostics, no other 
alarms are generated. 
•  Hard errors: 
Critical hardware errors/faults are reported 
RS232 
Selection of the interface type that the connect-
ed hardware (reader / optical readers) uses. 
The default value depends on the interface 
used. 
Note: This parameter is only shown when 
"MOBY Mode = Freeport" was selected. 
4.3.2  "Frame" parameter group 
In this parameter group, you can configure all parameters specific to the "Freeport". This 
parameter group is only displayed when you have selected the "Freeport" value in the "MOBY 
Mode" parameter. 
Table 4- 2  Parameters in the "Frame" parameter group 
Selection of the number of bits on which a 
character is mapped. 
Odd 
Even 
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".  
2 
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.
