Computer systems connected within a cascade arrangement are addressed
using up to four digits, two for each cascade level. The pairs of digits specify
which of the

COMPUTER CONNECTIONS

ports on each of the AdderView CATx

1000 units must be enabled to reach a specific computer. In the diagram given
here, a portion of the previous cascade diagram indicates how the routes to two
particular computers are formed and addressed.
Each cascade level requires two digits, hence the computer marked in red
requires a longer address (1203) as it is situated at cascade level 2, compared to
the blue computer at the top level with its two digit port number.
The first time that you make a connection between an AdderView CATxIP 5000
and an AdderView CATx 1000, the master unit will detect this and ask (via the
on screen menu) if you want to automatically add computers. If you choose
‘Yes’ then the ports on the cascade will be automatically added to the on screen
menu.

Using cascaded computers

In use, cascaded computers can be accessed using exactly the same methods
as for those connected directly to the AdderView CATxIP 5000. However, by
far the easiest way is to use the on screen menu. This is because it displays the
computer names and does not require any knowledge of port addresses. See
