When connecting remotely, be aware of the fact that there might be
some person operating the microscope locally, i.e. working directly
with the Microscope PC.
To close the remote connection to the Microscope PC, just close the
VNC Viewer window.
MICROSCOPE PC'S DESKTOP SHARING
Several users can connect to the Microscope PC at the same time
and thus share its desktop on the remote PC's. This can be used e.g.
for the educational purposes. The typical scenario is that a dedicated
user/supervisor controls the microscope (locally or remotely) and the
other connected users can only view the Microscope PC's screen
over the network.
1. In FEI User Management application, create a non-active user
account for the view only purpose.
2. Open the VNC Viewer application on the remote PC of the person
who is intended to control the microscope and connect remotely to
the Microscope PC as user/supervisor.
3. Other users will then open the VNC Viewer application on their
remote PC's and connect remotely as 'view-only' users.
Note:
The desktop sharing must be enabled in the VNC Server application
on the Microscope PC. For instructions how to do so, see
VNC Server
documentation available on the installation CD.
CONTROLLING THE MICROSCOPE REMOTELY
After connecting remotely to the Microscope PC, you can do all the
tasks as if you work directly with that computer. It is possible to control
the microscope operation, run the supportive applications, backup or
restore user data, view the log files etc.
In general, expect slower response on your commands and actions.
This limitation comes from the amount of data that have to be
transmitted and from the network bandwidth.
In case the xT microscope Control user interface stops responding or
the
Server Busy dialogue appears, the Microscope PC is probably
overloaded and may have problems with the actual conditions being
operated remotely. If such a problem occurs, wait till the Microscope
PC recovers; or restart it yourself when necessary.
Here are some recommendations for the remote control operation:
• Be very careful when navigating the stage. Always keep in mind
that what you see in the CCD camera image is not the exact
position of the stage (because of delay in imaging data
transmission).
• You can improve the performance / response time by setting the
more convenient scanning conditions: quad instead of full screen,
single quad running instead of more quads resumed; lower
resolution; slower scan (i.e. higher dwell time).
• Benefit from the automatic functions that are not affected by the
delayed response problem (Auto Contrast Brightness, Auto Focus,
Auto Stigmator). In case you prefer to focus or use the Stigmator
manually, it is better to do so in the reduced area.
