Lindy MC5-IP manual Addressing computers in a cascade, 43 41

Addressing computers in a cascade

The addressing format used by the MC5 units incorporates the various group numbers 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.

43 41 02		42 01
User	User	User	User
1	2	3	4

Each cascade level requires two digits, hence the computer marked in red requires a unique address with six digits because it is at cascade level 3, compared to the blue computer at level 2 with its four digit unique address. A computer connected directly to the MC5 at the top level would simply have a two digit port number.

The group at level 2 is numbered 41 because it is a quad group, connected to ports 1, 2, 3 and 4 on the MC5. If it was connected to ports 5, 6, 7 and 8, then the group number would be 42 and the overall address for the red computer would be 43 42 02.
