LAN interface messages
The IEEE Std 1174-2000 defines messages for serial interfaces to emulate interface messages of the GPIB bus. These messages also can be used for all LAN interfaces, especially for raw socket.
Command | Long term | Effect on the instrument |
---|---|---|
&ABO | Abort | Aborts processing of the received commands. |
&DCL | Device clear | Aborts processing of the received commands and sets the command processing software to a defined initial state. Does not change the instrument setting. |
>L | Go to local | Transition to the "local" state (manual control). The instrument automatically returns to remote state when a remote command is sent UNLESS &NREN was sent before. |
>R | Go to remote | Enables automatic transition from local state to remote state by a subsequent remote command (after &NREN was sent). |
&GET | Group execute trigger | Triggers a previously active instrument function (e.g. a sweep). The effect of the command is the same as the effect of a pulse at the external trigger signal input. |
&LLO | Local lockout | Disables transition from remote control to manual control via the front panel keys. |
&NREN | Not remote enable | Disables automatic transition from local state to remote state by a subsequent remote command. To reactivate automatic transition, use >R. |
&POL | Serial poll | Starts a serial poll. |
