Switching between Remote and Local Modes
When Switching from Local to Remote Mode
The 2558A switches to remote mode when it is in local mode and it receives a
:COMMunicate:REMote ON
command from the PC.
• The REMOTE indicator illuminates.
• All dials and switches are disabled except for the flipping of the OUTPUT switch to the LOCAL
side to change the 2558A to local mode.
• Settings entered in local mode are retained even when the 2558A switches to remote mode.
When Switching from Remote to Local Mode
When the 2558A is in remote mode and you flip the OUTPUT switch to the LOCAL side,
the 2558A switches to local mode. However, this does not work if the 2558A has received a
:COMMunicate:LOCKout ON
command from the PC. The 2558A switches to local mode when it
receives a
:COMMunicate:REMote OFF
command from the PC, regardless of the local lockout
state.
• The REMOTE indicator turns off.
• Dials and switches can be used.
• Settings entered in remote mode are retained even when the 2558A switches to local mode.
Note
You cannot use the Ethernet interface simultaneously with other interfaces (GP-IB and USB).
