Within the
Authentication
dialog, fill in your microscope
Username
, the corresponding
Password
and click the OK
button.
When this step successfully passes, a large window with the remote Microscope PC desktop opens.
The set connection is stored within the VNC Viewer as a corresponding icon.
7.
To close the remote connection to the Microscope PC, just close the VNC Viewer window.
Note
If the VNC viewer reports an error message instead of opening the remote Desktop, check that the VNC Server is running
on the Microscope PC, and the SharedData folder is accessible from the Microscope PC.
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 educational purposes. The typical scenario is that a dedicated user/supervisor controls the
microscope (locally or remotely): the other connected users can only view the Microscope PC's screen over the
network.
1.
Open the VNC Viewer application on the remote PC of the person who is to control the microscope and connect
remotely to the Microscope PC as a user/supervisor.
2.
Other users will then open the VNC Viewer application on their remote PC's and connect remotely as 'view-only'
users.
Note
Desktop sharing must be enabled in the VNC Server application on the Microscope PC. For instructions on how to do so, see
the VNC Server documentation available on the installation CD.
Controlling Microscope Remotely
When connecting remotely, be aware of the fact that there might be another person operating the microscope
locally, i.e. working directly with the Microscope PC.
After connecting remotely to the Microscope PC, you can do all the tasks as if you were working directly with that
computer. It is possible to control microscope operation, run the supportive applications, backup or restore user
data, view log files, etc.
In general, expect slower response to your commands and actions. This limitation comes from the amount of data
that has to be transmitted and from the network bandwidth, especially for network speeds below 10 Mbps.
In case the Microscope Control user interface stops responding or the
Server Busy
dialog appears, the Microscope
PC is probably overloaded and may have problems with the actual conditions being operated remotely. If such a
problem occurs, wait until the Microscope PC recovers, or restart it, if necessary.
Here are some recommendations for remote control operation:
•
To obtain better remote performance, try to use the
View
menu /
Remote Mode
item (see Chapter 3).
•
Be very careful when navigating the stage. Always keep in mind that because of delays in imaging data transmission,
what you see in the optical display is not the exact position of the stage.
•
You can improve the performance / response time by setting the more convenient scanning conditions: the
quad image instead of the single image mode, single live display instead of more live displays; lower resolution
and 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 correct astigmatism manually, it is better
to do so in a reduced area.
