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.
See "LAN Services" on page 116.

1. Connect the instrument and the remote computer to a LAN, see Chapter 2.6.1,
"Connecting the Instrument to the Network", on page 35.
2. Install the Ultr@VNC application and enable it on the instrument.
3. In the ICF firewall, enable communication on the network via Ultr@VNC program.
4. Install the VNC Viewer on the remote computer with Windows operating system,
see "Installing the VNC Viewer on a Windows PC" on page 42.

a) the remote computer with Linux/Unix operating system, see "Setting up the
VNC connection on the Linux/Unix remote computer" on page 43;
