When a DHCP server is used, a new IP address may be assigned each time the PC is
restarted. This address must first be determined on the PC itself. Thus, when using a
DHCP server, it is recommended that you use the permanent computer name, which
determines the address via the DNS server (see
"Using a DNS server to determine the
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 instrument to the LAN. Contact your net-
work administrator to obtain a valid IP address.
Assigning the IP address on the instrument
1. Press the [SETUP] key.
2. Press the "N Remote" softkey.
3. Select the "Network" tab.
4. In the "N Remote" dialog, toggle the "DHCP On/Off" setting to the required
mode.
If DHCP is "Off", you must enter the IP address manually, as described in the fol-
lowing steps.
Note:
When DHCP is changed from "On" to "Off", the previously set IP address
and subnet mask are retrieved.
If DHCP is "On", the IP address of the DHCP server is obtained automatically. The
configuration is saved, and you are prompted to restart the instrument. You can
skip the remaining steps.
Note:
When a DHCP server is used, a new IP address may be assigned each time
the instrument is restarted. This address must first be determined on the instrument
itself. Thus, when using a DHCP server, it is recommended that you use the per-
manent computer name, which determines the address via the DNS server
(See
"Using a DNS server to determine the IP address"
ter 5.1.5.3, "Using Computer Names"
5. Enter the "IP Address", for example
192.0.2.0
. The IP address consists of four
number blocks separated by dots. Every block contains a maximum of 3 numbers.
6. Enter the "Subnet Mask", for example
255.255.255.0
. The subnet mask consists of
four number blocks separated by dots. Every block contains a maximum of 3 num-
bers.
7. Close the dialog box.
If you have entered an invalid IP address or subnet mask, the message "out of
range" is displayed in the status line. If the settings are correct, the configuration is
saved, and you are prompted to restart the instrument.
