GP-IB Interface Functions
Listener function
• All of the settings that you can enter with the
panel keys can be set through the GP-IB
interface except for turning ON/OFF the power
and setting the communication parameters.
• Receives commands from a controller requesting
the output of setup information, measured data,
and other information.
• Also receives status report commands.
Talker function
Outputs setup information, measured data, and

Switching between Remote and Local
Modes
When switching from local to remote mode
Receiving a REN (Remote Enable) message from
the controller when the instrument is in the local
mode causes the instrument to switch to the remote
mode.
• The REMOTE indicator turns ON (see page 2-1).
• All keys other than the LOCAL key are locked.
• The settings that existed in the local mode are
maintained even when the instrument switches to
the remote mode.
When switching from remote to local mode
Pressing the LOCAL key when the instrument is in
the remote mode causes the instrument to switch to
the local mode. However, this act is invalid if the
instrument has been set to Local Lockout mode
(see next page) by the controller.
• The REMOTE indicator turns OFF.
• Key operations are enabled.
• The settings that existed in the remote mode are
maintained even when the instrument switches to
the local mode.
