To access the “Virtual Network Computer (VNC)” configuration menu (Fig. 24), call up
the main menu by hitting the appropriate hot key combination (the default is “Print
Screen” + “Print Screen”) and selecting “Virtual Network Computer”.
1. VNC Server Port Number: 5900
Normally, this is 5900, which is the default port for the first VNC display on a
VNC server. It is easy to specify a different port number from the VNC client, just
append it after the host name with a colon (target: 123, for example).
2. VNC Bandwidth Goal: Min, Medium, Max
This influences the trade-off between speed and compression. On the “Min”
setting, the maximum amount of video compression is performed, but that
consumes some time. In the “Max” mode, the video is not compressed at all, it’s
just set as quickly as possible. “Max” mode is useful on local area networks. Of
course, “Medium” is a compromise that does some compression. We recommend
“Max” for local area networks (10Mb and above), and “Min” for links with less
than 256Kbps bandwidth. Everything else should be used with “Medium”.

3. Network Bandwidth Used: 0.2Kbps (This is a read-only value.)
4. Max Resolution (Expected)
The initial size of the VNC client window is controlled here. Most users will want
to leave this control at “auto”, which picks the highest resolution the Unit has
ever observed from the server.
5. VNC Escape Key:
The VNC escape key cannot be changed from the local console. You must use the web
interface instead. This key is used to “escape” normal operation and get into the menu
system. Over a VNC connection, the same key (again, pressed twice quickly) is used to
pull up a small menu of useful functions while online. The default keyboard exit key is
“Scroll Lock”.
