5.11 24V I/O port
The PITreader has a 24V I/O port. No function is assigned to the I/O port upon delivery.
The I/O port can be configured either as an output or an input in the web application.
I/O port as output
If the I/O port is configured as an output, the current authentication status can be output via
this output.
In the web application it is possible to set the minimum permission on the transponder key,
from which point the output is to be switched on. If the permission on the transponder key is
equal to or higher than the set permission, the output assumes the "1” state.
I/O port as input
If the I/O port is configured as an input, an authentication block can be activated via this in-
put. The authentication block is active as long as 24 V is present at the input.
Note: The authentication block functions irrespective of the authentication type "single au-
thentication" (see Authentication types [ 18]).
5.12 Connect the base unit to a safe evaluation unit
A safe evaluation unit PITm4SEU can be connected to the PITreader via the terminals
TxD/RxD of X1 (see also PITm4SEU operating manual).
