2.7.2 Remote Access via a VNC Client Software
A VNC client software is an application which can be used to access and control the
instrument from a remote computer via LAN.
The following description explains how to establish the remote access, represented by
means of the client software Ultr@VNC. The software is included in Linux/Unix operat-
ing system, but it is also available as a free-of-charge download on the Internet
http://
www.uvnc.com/download/index.html . Thus, it is also available for remote computers
with Windows operating system.
The GUI appearance of Ultr@VNC may vary if you use a later release. Also, similar
programs may deviate in some details, but the basic procedure is the same.
Risk of Unauthorized Access
If the VNC service is enabled on the instrument, any user in the network who knows
the computer name and password can access it.
Disable the VNC service on the instrument to prevent unauthorized access.

"LAN Services" on page 116.
