Addressing computers in a cascade

The addressing format used by the AdderView CATx units incorporates the various group letters along with a final specific port number to which a required computer is attached. In the diagram given here, a portion of the previous cascade diagram indicates how the routes to particular computers are formed and addressed.

Each cascade level requires a group letter followed by a two figure final port number, hence the computer marked in red requires a longer address it is at cascade level 3, compared to the blue computer at level 2 with its shorter unique address. A computer connected directly to the AdderView CATx at the top level would simply have a two digit port number.

The group at level 2 is lettered ‘A’ because it is connected to ports 1, 2, 3 and 4 on the AdderView CATx. If it was connected to ports 5, 6, 7 and 8, then the group letter would be ‘B’ and the overall address for the red computer would be CB02.

The first time that you make a connection between two AdderView CATx units, 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.
