LAN Interface
The LAN LED
When the LAN connection is made, you will see the following indicators:
There may be a delay between making the LAN link (yellow status) and
getting the IP address (green status). This delay may be longer if there is
no DHCP server, for example when the instrument is connected directly to
a PC.
The LAN Reset button
This recessed button has two functions:
• Pressing the button briefly invokes a preset of the instrument and
restores default measurement settings. This is equivalent to the
following programming command:
:SYSTem:PRESet
• Pressing and holding the button for 5 seconds will reset the LAN
parameters to the factory default. This includes removing the password.
This is equivalent to the following programming command:
:SYSTem:COMMunicate:ETHernet:RESet
