Installation
The PrismaPro uses IPv4 IP addresses. IPv4 IP addresses consist of 32 bits in dotted decimal notation.
They consist of four decimal numbers that are each separated from 0 to 255 by bots, for example:
192.168.1.100. Each part represents an octet. Normally, IP addresses comprise one network prefix and
one host protocol.
Setting IP addresses
► Recommendation: Use static IP addresses.
► Do not use dynamic IP addresses.
► An alternative to changing the IP address is to change the IP address of the host computer, thus
5.6.2 Sub-networks
Standard subnet mask of the PrismaPro
● Subnet mask: 255.255.0.0
A sub-network is a logical visual sub-division of an IP network. Dividing an IP network into several sub-
networks is known as sub-netting. Sub-netting sets the region of the IP address that is used as a net-
work prefix for all IP addresses within a sub-network. This is carried out via the subnet mask.

Tbl. 11:
The subnet masks define which octets of the IP address are used as a network prefix. To allow 2 net-
work devices to communicate, these must be located in the same sub-network. This means that they do
not only have to be connected in the same internet network, but must also have the same network pre-
fix. If 2 devices have 2 different network prefixes, this means that both devices are located in different

sub-networks.

5.6.3 Changing the PrismaPro IP address
Procedure
► Change the unit's IP address using the Web UI.
► Change the unit's IP address with PV MassSpec Search.
5.6.4 Changing the host computer IP address
36/86
– You can set and change static IP addresses manually.
– A host (DHCP) sets these IP addresses automatically.
enabling communication between the host computer and the unit.

Operating instructions for Web UI and PV MassSpec
You can obtain information regarding operation of the PrismaPro via the Web UI and PV
MassSpec in the separate operating instructions for Web UI and in the software documen-
tation for PV MassSpec.
Administrator rights
The following steps apply to the Windows 7 operating system. Changing the host computer
IP address requires administrator rights. Contact your system administrator if necessary.
Ex factory IP address 192.168.1.100
The unit is assigned the IP address 192.168.1.100 at the factory. You cannot use it here.
