3.3 Switchover to Remote Control
On power-on, the instrument is always in the manual operating state ("LOCAL" state) and can be
operated via the front panel.
It is switched to remote control ("REMOTE" state)
IEC/IEEE bus as soon as it receives an addressed command from a controller.
RS-232 as soon as it receives the command "@REM" from a controller.
RSIB as soon as it receives an addressed command from a controller.
During remote control, operation via the front panel is disabled. The instrument remains in the remote
state until it is reset to the manual state via the front panel or via remote control interfaces. Switching
from manual operation to remote control and vice versa does not affect the remaining instrument
settings.

Via IEC bus:
CALL IBFIND("DEV1", analyzer%) ’Open port to the instrument
CALL IBPAD(analyzer%, 20) ’Inform controller about old address
CALL IBWRT(analyzer%, "SYST:COMM:GPIB:ADDR 18")’Set instrument to new address
CALL IBPAD(analyzer%, 18) ’Inform controller about new address
