External VNC Viewer
Limitations for Special Characters
Some special characters might not be transmitted through the VNC connection. The processing of special characters depends on the following factors:
- Keyboard layout configured on the VNC client and on the VNC server 
- VNC viewer in use: An external viewer and the internal viewer behave differently. 
- Firmware version of the endpoint device 
- UMS user interface: The UMS Console and the UMS Web App have different VNC viewers. 
You can specify an external VNC Viewer program from another provider in the UMS Console:
→ Click on Misc > Settings > Remote Access.
To pass on the IP address of the device to an external application, add the parameters and in External VNC Viewer.
Examples:
- TightVNC: - "C:\Program Files\TightVNC\tvnviewer.exe" <hostname>:<port>
- UltraVNC: - "C:\Program Files\uvnc\UltraVNC\vncviewer.exe" -connect <hostname>:<port>
- RealVNC: - "C:\Program Files\RealVNC\VNC Viewer\vncviewer.exe" <hostname>:<port>
- TigerVNC: - "C:\Program Files\TigerVNC\vncviewer.exe" <hostname>:<port>
Place the program path in double quotation marks as shown above to ensure that the call-up works even if there are spaces in the path.
