4.3.4.2 “IO-Modul-Einstellungen” (IO module settings) group box
The reader is supplied either with an Ethernet or RS 485/422 interface depending on its features.
The confi guration of the interface can be adapted to the application using this group box.
Note
Incorrect settings can result in an interruption of the connection to the reader. The settings on
readers without USB can only be reset using an interface that matches the confi guration.

The card type for the reader can be set in the “Modultyp” (Module type) drop-down list box. The
remaining confi guration boxes in this group box are activated depending on the card type selected.
The following settings are possible:
- Autodetect:
The reader detects which I/O card is installed. The settings for the card detected are made in
accordance with the default confi guration (see section 4.3.4.3).
- RS 485:
The reader expects a corresponding RS 422/485 card. To set the interface type from RS 485
to RS 422, the RS 422 check box must be selected. It is also possible to enable pull-ups and a
terminating resistor in the receive and transmit path. The terminating resistor is imperative for
a reliable point-to-point connection. It should only be deactivated in RS 485/422 networks in
which the reader is not installed at one of the ends of the network. The data transfer can also be
made using two stop bits. The transmission speed is set in the “Baudrate” drop-down list box.
The parity is set in the “Parität” (Parity) box to suit the required setting.
- Ethernet:
If the “Ethernet” module type is selected, it is possible to enter the network name and IP address.
If DHCP is activated by selecting the check box with the same name, the reader logs into the
DHCP server in the network and gets its IP address from there. For this reason the “IP-Adresse”
(IP address) fi eld is also deactivated. An appropriate network name can still be entered; this name
can then be used to communicate with the reader in the network provided there is an appropriately
confi gured DNS server.
