20 Chapter 2 Installation
VNC SERVER SOFTWARE If you want to use the Computer Screen media item in WATCHOUT to integrate
a live computer display into your presentation (for example, to display Excel or
Powerpoint as part of a speaker-support presentation), you must install VNC
server software on the remote computer. This must be a separate computer – it
can not be one of the computers running WATCHOUT software.
◆ NOTE: This software is not required for basic WATCHOUT functions. You
only need to install this software if you want to use the “Computer Screen”
feature (see “Add Computer Screen” on page 143).
VNC (Virtual Network Computing) server software is available for a wide
variety of operating systems. The instructions below describe its installation
under Windows. VNC is free software, available in several forms:
http://www.realvnc.com/
http://ultravnc.sourceforge.net/
Download the VNC server software from one of the above locations, and
follow its installation instructions. When using Windows 7, you’re advised to
start the VNC server software as a user mode application.
For best performance, use a reasonably fast computer to run the VNC server
software and the application you wish to incorporate into your presentation
(for example, Powerpoint).
Make sure that the VNC server computer is connected to the WATCHOUT
network, and has a fixed, known IP number in its TCP/IP settings (see
page 24). This IP number and other TCP/IP parameters must match the
network to which it is connected. Also verify that its firewall is disabled, or that
the VNC port 5900 is open in the firewall (see “Firewall Settings” on page 25).
