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.
