Switching to Remote Control

After switching on, the instrument is usually in the local state and can be operated via the front panel controls (for instruments equipped with a display), a mouse and an external keyboard.

Starting remote control
  1. Send a command from a controller to the instrument.

    The instrument changes to remote state as soon as it receives the command from the controller.

    Note: If you have sent &NREN before, the automatic transition from local state to manual control by a subsequent remote command is disabled (use &GTR to enable it again).

    In remote state, operation via the front panel or via mouse and keyboard is disabled. The status line indicates the "REMOTE" state.

    The instrument remains in the remote state until it is reset to the local state, see "Returning to Manual Operation").

    Tip: Switching from manual operation to remote control and vice versa does not affect the other instrument settings.

  2. Although operation via front panel, mouse and keyboard is disabled, the dialog boxes can still be opened, for example to verify settings. The buttons and setting fields are grayed out and cannot be activated.

    Additionally, you can disable the access to the dialogs with the command SYST:KLOC ON to protect the instrument against unauthorized readings.

  3. To prevent unintentional return to manual operation, disable the LOCAL key of the instrument with the &LLO command (see "LAN Interface Messages").

    The instrument switches to "REM-LLO" state.

    The automatic transition from local state to remote state by a subsequent remote command, and the command *GTL are disabled.

    To return to manual mode is only possible via remote control.

  4. Unlock the LOCAL key with &GTR.
