The screen displays the receive power over the last three minutes. This will allow the installer
to slowly sweep the antenna during installation and monitor the variation in signal strength
with angular position. The screen automatically refreshes every three seconds.
The screen also displays the current state of the wireless link in two ways. First, the actual
state of the wireless link is written in the top left corner of the screen. The instantaneous
receive power bar also encodes the state of the wireless link using green to signify that the
wireless link is up and red for all other states.
For the more technically, aware the installation metric is simply the instantaneous receive
power in dBm + 100.
The PDA installation tool is accessed via a hidden URL http://<ip-address>/pda.cgi. It should
be noted that this link is only available after the user has logged in as system administrator.
The large screen version of the graphical user interface is available as a submenu option of
the installation wizard.

The 600 Series system has two software image banks; one is a fixed image which is stored in
protected non-volatile memory and cannot be modified by the user. The second bank is used
by the system administrator to upgrade the firmware when necessary. Figure 56 shows the
main software upgrade web page.
