Setting up a VNC connection with a dedicated desktop client
Prerequisite: the controller PC and the R&S LCX are connected in a LAN, see "Estab-
lishing the LAN connection" on page 24.
The controller PC requires a dedicated VNC client application. The operating systems
Linux/Unix provide a build-in VNC client, but for Windows operating systems, you must
have installed a VNC client software on the controller PC.
Various free-of-charge applications are available for download on the Internet.
This example refers to an application on a Windows client.
To enable the VNC connection, follow the instructions given under Enabling the VNC
service for remote access:
1. To launch the VNC client application on the controller PC:
a) On the Internet, download a VNC client application, e.g. the Real VNC, see
https://www.realvnc.com.
b) Start the VNC client installation.
c) Select the VNC viewer component and follow the installation instructions.
d) When completed, confirm the installation.
2. Start the VNC client.
3. Enter the IP address of the R&S LCX in the address line.
The address string follows the syntax:
<ip address or hostname>[:port], e.g., //192.168.0.128:5678
Note: If you use a port number different from the default port 5900, you must add
this number to the IP address.
Note that when you reconnect, the changed port number is not retained, but reset
to default.
To save a connection with a different port, bookmark this page with the port number
contained in the address string.

Note: If the connection is interrupted accidentally, e.g. by a reboot of the instru-
ment, the VNC client does not re-establish the connection automatically.
