6.1.5. I/O card conguration
The communication interface settings can be changed using the IO card conguration. All available I/O cards are
displayed here in the form of tabs. Clicking on the respective tab opens the associated card and displays all respective
conguration parameters, together with the card type that was detected.
Under the IO card type header there is a drop-down menu, in which the card type can be set to Auto detect, Card not
used or to the actual card type. Automatic detection restores the interface to the default settings. What these settings
are is described in the following sections in relation to the interfaces. If the card type is set to not used, this interface
can no longer to used.
All card-specic conguration parameters are displayed on the card sheet when the recognised card type is set.
These parameters are described in the following sections for the respective card. The settings are saved to the
reader by pressing the Save changes button.
Note
The new parameters, provided nothing to the contrary is specied for the specic card, become valid only when the
reader has been restarted. If incorrect parameters are loaded, the reader can no longer be accessed!
The serial interface supports communication to the EIA232 standard and, depending on the expansion stage, has ve
outputs for activation of LEDs. The conguration parameters are split between the Port settings and Output headers.
