Setting the password from a command interface
The password is set (or changed) by setting the localnode.password attribute. For example:
localnode.password = "Keithley"
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 Series 2600B 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 Series 2600B 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 Series 2600B 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 Series 2600B is unlocked and communicates with any remote interface.
