Chapter 9 Operation with a Computer
IP address Identifies each device connected on a network.
Each network device must be set to a unique address.
The instrument supports IP version 4, with IP addresses indicated as four deci-
mal octets, e.g., "192.168.0.1".
Subnet mask This setting is used to distinguish the address of the network from the addresses
of individual network devices.
The normal value for this setting is the four decimal octets "255.255.255.0”.
Default Gateway When the computer and instrument are on different but overlapping networks
(subnets), this IP address specifies the device to serve as the gateway between
the networks.
If the computer and instrument are connected one-to-one, no gateway is used,
and the instrument's default setting "0.0.0.0" can be kept as is.
Network Environment Configuration
Setting Items
Example 1. Connecting the instrument to an existing network
To connect to an existing network, the network system administrator (IT department) has to assign settings
beforehand.
Some network device settings must not be duplicated.
Obtain the administrator's assignments for the following items, and write them down.
IP Address ___.___.___.___
Subnet Mask ___.___.___.___
Default Gateway ___.___.___.___
Example 2. Connecting multiple instruments to a single computer using a hub
When building a local network with no outside connection, the following private IP addresses are recom-
mended.
Configure the network using addresses 192.168.1.0 to 192.168.1.24
IP Address ........................... Computer:192.168.1.1
Power Analyzers: assign to each instrument in order 192.168.1.2,
192.168.1.3, 192.168.1.4, ...
Subnet Mask........................255.255.255.0
Default Gateway ..................0.0.0.0
Example 3. Connecting one instrument to a single computer using the 9642 LAN
Cable
The 9642 LAN Cable can be used with its supplied connection adapter to connect one instrument to one
computer, in which case the IP address is freely settable. Use the recommended private IP addresses.
IP Address ........................... Computer:192.168.1.1
Power Analyzers:192.168.1.2 (Set to a different IP address than the com-
puter.)
Subnet Mask........................255.255.255.0
Default Gateway ..................0.0.0.0
