Connection via LAN
In order to activate the Ethernet port for communication, you must program a valid IP ADDRESS in
the cash register. This can be done in P-Mode by entering 97 on the TYPE key. The address
consists of the three values IP BASE ADDRESS, SUBNET MASK and DEFAULT GATEWAY.
The IP base address is the number of the register in the Ethernet network. Please note, that any
address of the network must be unique to avoid conflicts with other devices. The subnet mask is
used to specify the address range of the local network. It depends on the local network. In most
cases it is set to 255.255.255.0 which means that the first 3 parameters specify the LOCAL
network and the last the device in the network. The Default Gateway is the address of the
ROUTER when used. When the IP address is not on the LOCAL network (checked by
SUBNETMASK) this address will be used instead.
Please note that the programmed address must fit to the network settings in your PC. For further
information please check the additional programming guides or ask your local dealer and network
specialist.
