Setting the password from a command interface
The attribute
localnode.passwordmode
enables passwords and sets the mode. The password
mode identifies which interface to password protect.
Use one of the following attributes to set the password mode.
•
localnode.PASSWORD_WEB
. Passwords are only required for the web interface.
•
localnode.PASSWORD_LAN
. Enables passwords on all Ethernet and web interfaces.
•
localnode.PASSWORD_ALL
. Protects the LAN and all command and web interfaces.
•
localnode.PASSWORD_NONE
. Disables all passwords.
The password lock feature on 2606B is similar to the lock feature on your computer.
You must enable passwords to use this feature.
To lock the instrument when you are away from the testing area, send the following command:
password
The remote interface is locked. The module of the 2606B does not respond to commands issued from
the command interface until you unlock the interface. This reserves the instrument and protects the
test script running on the instrument.
Unlocking the remote interface
If the remote interface is locked, you must enter the password before the module of the 2606B
responds to any command issued over a remote interface.
The password for the example below is
Keithley
.
To unlock the remote interface, send the following command:
password Keithley
The module of the 2606B is unlocked and communicates with any remote interface.
Resetting the password
If you forget the password, you can reset the password from the virtual front panel. Once you enable
the password feature, the 2606B stores this password until the LAN configuration is reset or until you
reset the password.
To reset the password:
•
From the virtual front panel, press the
MENU
key, and then select
RESET-PASSWORD
.
If you reset the LAN settings, you must re-enable the password feature.
