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.
The same numbering notation applies as for the IP address. A value of 0.0.0.0 indicates that no default
gateway 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.
Default Settings
Select Default Settings to reset the LAN to the as-shipped (or default) settings. This returns ALL LAN
settings to the as-shipped values and restarts networking. All default LAN settings are listed under
Non-volatile Settings
GPIB/USB Configuration
You can configure the USB and GPIB interfaces as follows:
Front Panel Reference SCPI Command
Press the [Menu] key. Select System\ IO\ USB\ Settings
Use the rotary knob to scroll through the list.
Select Enabled to enable or disable the GPIB or USB
interface.
Not available
There are no configurable USB parameters. You can retrieve the USB connect string using the front
panel menu:
The GPIB configuration is only available on instruments with Option GPB. Each device on the GPIB
(IEEE-488) interface must have a unique whole number address between 0 and 30. The instrument
ships with the address set to 5. Your computer’s GPIB interface card address must not conflict with any
instrument on the GPIB interface bus. This setting is non-volatile; it will not be changed by power
cycling or *RST.
