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.

&GTL

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.

&GTR

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 &GTR.

&POL

Serial poll

Starts a serial poll.
