local mode.
Remote mode: · In this mode, the host can control the MX61/61L to execute an operation or setting using
an request command. In this mode, the MX61/61L can be controlled exclusively using the
request commands.
· The status of the MX61/61L can be checked using the query commands.
· The four buttons on the microscope front panel (hereinafter referred to as the “front panel
switches”) and the buttons on the hand switch are extinguished in this mode.
Local mode:
· In this mode, the MX61/61L cannot be controlled using the request commands from the
host. The microscope can be controlled exclusively using the front panel switches, hand
switch and the external control of the revolving nosepiece.
