Switching between Remote and Local Mode
When Switched from Local to Remote Mode
Remote mode is activated when the
:COMMunicate:REMote ON
command is
received from a controller while local mode is active.
• The REMOTE indicator is turned ON.
• All keys except the LOCAL key are disabled.
• Settings entered in local mode are retained even when switching to remote mode.
When Switched from Remote to Local Mode
Pressing LOCAL in remote mode puts the instrument in local mode. However, this is
not possible when the
:COMMunicate:REMote ON
command is received from the
PC while Local Lockout mode is active. Local mode is activated when the
:COMMunicate:REMote OFF
command is received regardless of Local Lockout.
• The REMOTE indicator is turned OFF.
• Key operations are enabled.
• Settings entered in remote mode are retained even when switching to local mode.
Note
The Ethernet interface cannot be used simultaneously with other communication interfaces (GP-
IB, or serial (RS-232)).
