RS-232C Serial Commands

Command Description

%GL Go to local – enables System touch screen controls.

NOTE: In accordance with the IEEE-488.2 standard, the System

still responds to remote commands in when in local mode.

%LL Local lockout – the System touch screen controls are disabled, and

no “Return to local” button appears on the panel.

%RM Go into remote mode – the System touch screen controls are

disabled, but a “Return to local” button appears.

NOTE: When in remote mode, the touch screen controls will be

disabled each time the System receives a command.

%S? Read the status byte by performing a serial poll.

bit 7 – ready

bit 6 – request for service (RQS)

bit 5 – standard event status (ESB) summary bit

bit 4 – message available (MAV) (always 0 for RS-232)

bit 3 – temperature event (TESR) summary bit

bit 2 – device specific error (EROR) summary bit

bit 1 – not used (always 0)

bit 0 – not used (always 0)

NOTE: The “request for service” flag (bit 6) is automatically reset

when a serial poll is performed.

! Device clear – clears the serial communications subsystem. The

System will echo back the “!” when the command has completed. If

the “!” response is not received, the command should be retried.

NOTE: This command is sent as a single character (no line feed

terminator), and should never otherwise appear in a string sent to

the System.

^ The System sends a “^” as a service request (SRQ) indicator in

serial mode.

NOTE: The “^” character will never otherwise appear in a response

string, and is sent as a single character.
