Preparing for LAN Communications
Example of establishing a network environment
(1) Connecting the instrument to an existing network
Hub
To connect to an existing network, the network system
administrator (IT department) has to assign the settings
beforehand.
The settings must not overlap with another device.
Obtain assignments from the administrator (IT department)
for the following items, and write them down.
IP address . . .
Subnet mask
. . .
Default gateway
. . .
(2) Connecting multiple instruments to a single computer using a hub
Hub
When building a local network with no outside connection, it
is recommended to use the following private IP addresses.
Example: When building the network using network addresses 192.168.1.0/24 (192.168.0.1 to
192.168.1.255)
IP address
Computer: 192.168.1.1
Instrument (rst): 192.168.1.2
Instrument (second): 192.168.1.3
Instrument (third): 192.168.1.4
In this way, assign the addresses in order.
Subnet mask
255.255.255.0
Default gateway
Computer : . . .
Instrument : 0.0.0.0
(3) Connecting one instrument to a single computer using the Model 9642 LAN cable.
When connecting one instrument to a single computer using
the conversion connector supplied with the Model 9642 LAN
cable, variable IP address can be set but it is recommended to
use private IP addresses.
Example: When building the network using network addresses 192.168.1.0/24 (192.168.0.1 to
192.168.1.255)
IP address
Computer : 192.168.1.1
Instrument : 192.168.1.2
(Set to a different IP address than the computer.)
Subnet mask
255.255.255.0
Default gateway
Computer : . . .
Instrument : 0.0.0.0
