Operating the reader in DHCP client mode
In "DHCP" IP mode, the code reader obtains its network address from a DHCP server.
Note
Unique reader device identifier on the nameplate
Depending on the network structure, the DHCP server needs to be informed of the MAC
address, the unique device identifier of the reader. You will find the MAC address, for
example on the rating plate of the reader.
Note
DNS name for the reader
If your network administrator can assign a DNS name (Domain Name Service) for the
reader, you can address the device using its name in much the same way as an intranet
server.
Operating the reader with a static IP address
Assign the network address manually in "Manual" IP mode. Enter the IP address and the
subnet mask to suit your network configuration and, if applicable, a gateway address.
Note
IP address in the same subnet as the IP address of the communications partner
The IP address of the reader must be in the same subnet as the IP address of the
communications partner.
Note
Gateway not required for direct connection
A gateway is not necessary for a direct connection between the reader and a PC/PG.
Operating the reader in DHCP server mode
In "DHCP server" mode, a connected client can obtain its IP address from the reader. No
other DHCP server may be activated in the network. In this mode, you can connect up to
four PCs to the reader via a switch since a maximum of four IP addresses can be assigned
automatically.
