3 Getting Started
Host Name
A hostname is the host portion of the domain name, which is translated into an IP address. To
configure the hostname of the instrument:
Front Panel Menu Reference
Select System\IO\LAN\Modify\Name
You can enter any value from the numeric keypad. For additional
characters, use the up/down navigation keys to enter an alpha
character by scrolling through the selection list that appears when
you press the keys. Use the left/right navigation keys to traverse the
text field. Use the backspace key to delete a value. Press Enter when
you are finished.
Host Name - This field registers the supplied name with the selected naming service. If the field is left
blank, no name is registered. A hostname may contain upper and lower case letters, numbers and
dashes (-). The maximum length is 15 characters.
Each instrument is shipped with a default hostname with the format: K-modelnumber-serialnumber,
where modelnumber is the unit's 7-character model number (e.g. RP7951A), and serialnumber is the
last five characters of the 10-character serial number located on the label on the top of the unit (e.g.
45678 if the serial number is MY12345678).
DNS Server
DNS is an internet service that translates domain names into IP addresses. It is also needed for the
instrument to find and display its hostname assigned by the network. Normally, DHCP discovers the
DNS address information; you only need to change this if DHCP is unused or not functional.
To manually configure the DNS services:
Front Panel Menu Reference
Select System\IO\LAN\Modify\DNS
Select Primary Address or Secondary Address. See below for a full
description.
Primary Address - This field enters the primary address of the server. Contact your LAN admin-
l
istrator for server details. The same numbering notation applies as for the IP Address. A value of
0.0.0.0 indicates that no default server is defined.
Secondary Address - This field enters the secondary address of the server. Contact your LAN
l
administrator for server details. The same numbering notation applies as for the IP Address. A
value of 0.0.0.0 indicates that no default server is defined.
Dot-notation addresses ("nnn.nnn.nnn.nnn" where "nnn" is a byte value from 0 to 255) must be expressed with
care, as most PC web software interprets byte values with leading zeros as octal (base 8) numbers. For example,
"192.168.020.011" is actually equivalent to decimal "192.168.16.9" because ".020" is interpreted as "16"
expressed in octal, and ".011" as "9". To avoid confusion, use only decimal values from 0 to 255, with no leading
zeros.
