Subnet Mask  This value is used to enable the instrument to determine if a client IP address 
is on the same local subnet. When a client IP address is on a different subnet, 
all packets must be sent to the Default Gateway. 
Default 
Gateway 
This value is the IP Address of the default gateway that allows the instrument 
to communicate with systems that are not on the local subnet, as determined 
by the subnet mask setting. 
DNS  DNS is an internet service that translates domain names into IP addresses. 
This parameter indicates whether the IP address of the Domain Name System 
(DNS) server is obtained automatically or manually. Auto obtains the DNS 
server address from DHCP. Manual uses the DNS server in the following field. 
DNS Server  This value is the address of the Domain Name System (DNS) server. If DHCP 
is disabled, the DNS server parameter is needed for the instrument to be able 
to find and display its hostname. 
Naming 
Service 
This parameter specifies the Naming service, if any, to be used to register the 
instrument. NetBIOS indicates the instrument will be registered using the RFC 
NetBIOS naming protocol. Dynamic DNS indicates the instrument will be 
registered using the Dynamic DNS naming system. 
Host Name  This field registers the supplied name with the selected naming service. If the 
field is blank, no name is registered. A hostname may contain upper and lower 
case letters, numbers and dashes(-). The maximum length is 15 characters. 
The format is A-modelnumber-serialnumber. Modelnumber is the instrument’s 
6-character model number, and serialnumber is 5th through the 9th character 
of the 10-character serial number located on the label on the side of the unit. 
Domain  This field registers the Internet domain for the instrument. The Domain must 
start with a letter and may contain upper and lower case letters, numbers, 
dashes(-) and dots(.). 
Description  This field lets you assign a user-friendly name to the instrument. This name is 
used as the title of the instrument’s Web home page. 
LAN 
Keepalive 
Timeout 
This value sets the LAN keepalive in seconds. The instrument uses the LAN 
keepalive timer to determine if a client is still reachable. If there has been no 
activity on the connection after the specified time, the instrument will send 
keepalive probes to the client to determine if it is still alive. If not, the 
connection will be marked as down or "dropped." The instrument will release 
any resources that were allocated to that client. When setting this parameter, 
it is recommended that the largest value be used that still meets the 
application's need for unreachable client detection. Smaller keepalive timeout 
values will generate more keepalive probes (network traffic), using more of the 
available network bandwidth. Check the Enable box to enable the LAN 
Keepalive function. Allowed values: 720-99999 seconds. 
GPIB Address  This field shows the instrument's GPIB bus address. The GPIB address can be 
configured using the instrument's front panel. 
Change 
Password 
This field lets you change the Web password. Enter the old password to 
confirm access. Enter the new password in the Enter New field and in the 
Confirm New field. The password can be up to 12 alpha-numeric characters 
(letters, numbers, underscore); case insensitive. The first character must be a 
letter. If the fields are blank, password checking is disabled.
