Interfaces
In this area, you define the communication interfaces and the parameters for the interfaces.
Ethernet
In this group, you set the parameters for the Ethernet interface. This group is displayed once
or twice depending on the reader version used and the number of Ethernet interfaces
available. Note that you must operate the Ethernet interfaces "X1 LAN1" and "X2 LAN2" in
two different subnets.

Assignment of the IP address to the reader in the net-
work:
•

IP address
(only when IP
mode = manual or
DHCP server)
xxx.xxx.xxx.xxx
0.0.0.0
IP address of the Ethernet interface of the reader
(an IP address consists of four numbers separated by
periods with each number being in a range from 0 to
255.)
Subnet mask
255.xxx.yyy.zzz
255.255.255.0
Subnet mask
The subnet mask indicates which part of the IP address
specifies the network and which part specifies the reader:
If a bit is set in the binary representation of the subnet
mask, the corresponding bit of the IP address belongs to
the network address. If no bit is set, the bit belongs to the
address of the reader.
In binary terms, xxx.yyy.zzz requires that the left part be
made up of ones without a gap and the right part be
made up of zeros without a gap. Example:
11111111.10100000 is not permitted.
Note also: zzz ≤ 254
