GP-IB Interface Functions
Listener Capability
• All of the information that you can set 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 data, measured data, and other
information.
• Also receives status report commands.
Talker Capability
Outputs setup data, measured data, and other
information.

on this instrument.
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 (see section 1.2) is turned
ON.
• All keys other than the LOCAL key are locked.
• Settings entered in local mode are retained even
when the GS610 switches to remote mode.
When Switching from Remote to Local Mode
Pressing LOCAL in remote mode puts the instrument
in local mode.
• The REMOTE indicator turns OFF.
• Key operations are enabled.
• Settings entered in remote mode are retained even
when the GS610 switches to local mode.
