OVERVIEW
about putting in a
expansion chassis (like the fully loaded one shown at right) or 8-
or 16-user chassis. They come empty (no cards installed), but you can
install 1 expansion card (or 2 in the 16-user units) and add as many
as 4 Port Cards (0 x 4 or 1 x 4) to them, giving you a maximum of 4,
8, or 16 user stations and 16 CPUs attached to each unit.
designed for, only that many video paths can be open through that
unit at a time. For example, a 4-user unit only has four video paths. If

accept only 8-User Expansion Cards like the one shown below.
The 16-user units accept two of the 8-User Expansion Cards.
The 8-User Expansion Cards have jumper blocks that you can set

If all of your users are on one chassis, use the regular bus topology
(above, left).
If you have two users on one chassis and two on another,
use the “split bus” topology (above, middle).
If your users are spread across several chassis, use the ring
topology (above, right). Keep in mind that only one user at
a time can use the bus that interconnects daisychained
