Instrument access
You can specify that the control interfaces request access before taking control of the instrument.
There are several modes of access.
You can set one of the following levels of access to the instrument:
• Full: Allows full access for all users from all interfaces
• Exclusive: Allows access by one remote interface at a time with logins required from other
interfaces
• Protected: Allows access by one remote interface at a time with passwords required on all
interfaces
• Lockout: Allows access by one interface (including the front panel) at a time with passwords
required on all interfaces
The front panel is read-only when you are using a remote interface. You can view information and
swipe screens without being prompted to leave remote mode. If you attempt to make a change from
the front panel while the instrument is controlled from a remote interface, you will be prompted to
enter a password to gain access.
When you set access to full, the instrument accepts commands from any interface with no passwords
required. You can change interfaces as needed.
When you set access to exclusive, you must log out of one remote interface and log into another one
to change interfaces. To use another interface, log out of the present interface before logging into the
new interface. You do not need a password with this access.
Protected access is similar to exclusive access, except that you must enter a password when logging
in.
When you set access to locked out, a password is required to change interfaces, including the front-
panel interface.

1. Press the MENU key.
2. Under System, select Settings. The SYSTEM SETTINGS menu opens.
