The currently active settings for the IP Address, Subnet Mask, and Default Gateway may be different
from the front panel configuration menu settings - depending on the configuration of the network. If
the settings are different, it is because the network has automatically assigned its own settings.
Modifying the LAN Settings
As shipped from the factory, the power system’s pre-configured settings should work in most LAN
environments. However, you can manually configure these settings as described:
Hostname
A hostname is the host portion of the domain name, which is translated into an IP address. To manually
configure the hostname use the rotary knob to select he Hostname field.
Enter values using the numeric keypad. For alpha characters, use the rotary knob to scroll through the
list that appears when you use the knob. Use the arrow keys to traverse the text field. Use the Enter
field enter the information.
The Hostname 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, 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).
Automatic IP address
Turns the automatic IP address function on or off.
On - automatically configures the addressing of the instrument. When selected, the instrument will
first try to obtain an IP address from a DHCP server. If a DHCP server is found, the DHCP server will
assign an IP address, Subnet Mask, and Default Gateway to the instrument. If a DHCP server is
unavailable, the instrument will try to obtain an IP address using AutoIP. AutoIP automatically assigns
an IP address, Subnet Mask, and Default Gateway addresses on networks that do not have a DHCP
server.
Off - lets you manually configure the addressing of the instrument by entering values in the following
three fields. These fields only appear when Manual is selected.
IP Address - This value is the Internet Protocol (IP) address of the instrument. An IP address is required
for all IP and TCP/IP communications with the instrument. An IP address consists of 4 decimal
numbers separated by periods. Each decimal number ranges from 0 through 255 with no leading zeros
(for example, 169.254.2.20).
Subnet Mask - This value is used to enable the instrument to determine if a client IP address is on the
same local subnet. The same numbering notation applies as for the IP address. When a client IP
address is on a different subnet, all packets must be sent to the Default Gateway.
