Transpector CPM Operating Manual
3.2.2 Subnetworking
An IP network can be split into multiple subnets. Subnetting sets a region of the
IP address as a Network Prefix for all IP addresses inside the subnet through a
subnet mask. The subnet mask determines which octets of the IP address are
used as the network prefix. (See Table 3-1.)
In order for two network devices to communicate, they must be on the same
subnet, be connected to the same internet network and have the same network
prefix.
NOTE: If two devices have different network prefixes, the two devices are on
different subnets.
3.3 Transpector CPM IP Address
The default Transpector CPM IP address is 192.168.1.100 with a subnet
mask of
255.255.0.0.
NOTE: When connecting to an existing local network, there must be a static
IP address for each Transpector RGA. Contact the network administrator
for IP address assignments.
Two methods of changing the Transpector CPM IP address are available.
INFICON Mass Spectrometer Search Utility. (See section 3.3.1.)
Transpector Web UI. (See section 3.3.1.2 on page 3-5.)
