2.6.2 Assigning the IP Address
Depending on the network capacities, the TCP/IP address information for the instru-
ment can be obtained in different ways.
●
If the network supports dynamic TCP/IP configuration using the Dynamic Host
Configuration Protocol (DHCP), all address information can be assigned automati-
cally.
●
If the network does not support DHCP, the instrument tries to obtain the IP address
via Zeroconf (APIPA) protocol. If this attempt does not succeed or if the instrument
is set to use alternate TCP/IP configuration, the addresses must be set manually.
By default, the instrument is configured to use dynamic TCP/IP configuration and
obtain all address information automatically. This means that it is safe to establish a
physical connection to the LAN without any previous instrument configuration.
Risk of network errors!
Connection errors can affect the entire network.
If your network does not support DHCP, or if you choose to disable dynamic TCP/IP
configuration, you must assign valid address information before connecting the instru-
ment to the LAN.
Contact your network administrator to obtain a valid IP address.
Assigning the IP address on the instrument
1. Press the SETUP key and select the "Network Settings" dialog.
2. Set the "Address Mode" to Static.
3. Select the "IP Address" and enter the IP address, for example
192.168.0.1.
.
The IP address consists of four number blocks separated by dots. Every block con-
tains 3 numbers in maximum.
4. Select the "Subnet Mask" and enter the subnet mask, for example
255.255.255.0
.
The subnet mask consists of four number blocks separated by dots. Every block
contains 3 numbers in maximum.
Use computer names to identify the instrument
In networks using a DHCP server, it is recommended that you address the instrument
by its unambiguous computer name, see
Chapter 2.6.3, "Using Computer Names"
on page 37.
A computer name (
hostname
) is an unique dedicated identification of the instrument,
that remains permanent as long as it is not explicitly changed. Hence, you can address
an instrument by the same identification (computer name), irrespectively if a network or
a point-to-point connection is used.
