Black Box ServSwitch CX 用户手册

®

The viewer window gives you the ability to view and control the ServSwitch 
CX with IP and its host server(s). Its operation is almost identical regardless of 
whether you used the VNC viewer or your Web browser to display it.

The viewer window presents a menu bar similar to that shown below. Certain 
items within the toolbar are displayed depending upon your access permissions 
and/or the ServSwitch CX with IP configuration.

Ensures that the 
mouse pointer 
which you move 
and the mouse 
pointer on the 
host system 
are correctly 
synchronised.

What is the best screen resolution to use?
The best resolution for your server is one that is larger than the screen of the host 
server that you are viewing. This will allow you to see everything without scrolling 
around. Alternatively, the VNC viewer can be set to scale the image to fit your screen, 
but remember that some pixel dithering effect will be seen when scaling is used. 

How do I navigate around a larger screen?
If the screen that you are viewing has a larger resolution than your viewing window 
you will need to scroll around to see all items. The viewer window allows you to 
‘bump scroll’ (only in full screen mode). This means that when your mouse cursor 
bumps against the edge of the screen, the screen image will scroll across automatically.  

How do I escape from full screen mode?
Press the F8 button. This button is changeable but is most often set to F8.  

This happens when a new host screen is viewed (that has not been viewed before). 
Click the 

 button to perform an auto calibration for the screen and the mouse. 

 for important information about this feature.

How do I change between host servers?
The best way to change between host servers is to click the ‘Hosts’ button and then 
select the required server by name. See 

.

How do I remove traces of moved items from the screen?
When you move an item or window across the screen, sometimes it can leave 
unsightly trails. These are called artifacts and can be particularly prevalent when the 
connection speed is low. To remove artifacts, click the ‘Controls’ button and select 
the ‘Refresh screen’ option. See 

How do I make the most of a slow connection?
The VNC viewer is slightly better suited to slower connections than the browser 
viewer because it offers more options. Click the 

when entering the ServSwitch CX with IP address during log on.  

Adjust the Threshold setting
Ensure that the video 

 is set higher than the automatic setting 

suggests. Tweak this setting manually to ensure the best setting.  

Fewer colours
Select the 

 mode. The Very low option offers hardly any 

improvement and looks a lot worse.

Rate limit mouse events
When selected, this mode greatly reduces the mouse movement data that are sent 
to the host server. When you move the local mouse, the remote cursor will catch up 
roughly once per second. 

Ctrl Alt Del

Sends the 
Ctrl Alt Del 
sequence to 
the current 
host server.
