11.5. Cautions in Operation
(1) Operation from the front panel is not accepted after the remote status is set up by
RS-232C communication.
(2) Operation from an external input is not accepted after the remote status is set up
by RS-232C communication.
However, EXT-PROTECT is active.
(3) If the filament is ON (including degassing ON) when the remote status is set up
by RS-232C communication, the action will be turned OFF.
(4) If the filament is ON (including degassing ON) when the remote status is reset
from the remote status to the local status through RS-232C communication, control
returns to the local status after turning OFF the action.
(5) If the RS-232C remote status is set up from the host computer and the power to
the host computer is turned OFF before it is reset to the local status, the vacuum
gauge side holds the remote status. To reset it, enter a local command from the
host computer again or turn OFF the power to the vacuum gauge.
