Backbone Network Guidelines
The backbone network topology uses a single
cable that passes through each external
interconnect module (EIM), as shown in Figures 2
and 3.
In Figure 2, the EIMs at each end of the backbone
must be terminated. All other interconnect points,
including the console, are unterminated.
Figure 2: Backbone Network Example #1.

In Figure 3, the console and the last EIM are
terminated. All other interconnect points are
unterminated.

Star Network Guidelines
The star network topology has legs running from a
hub (central connection) to the attached EIMs. The
console, a J-Box, or one of the domes or EIMs can
serve as the wiring point or "hub" for the star
configurations, as shown in Figures 4 and 5.
• Each network link supports one star network,
with up to 32 devices. VM96 supports up to
eight Touch Tracker controllers.
• Only one hub is allowed for each star network.
• A network hub supports a maximum of four
legs.
• The device at the hub is always unterminated.
• A star network leg can attach unterminated
connected devices; however, the device at the
end of each leg must be terminated.
In Figure 4, the EIMs at the end of each leg must
be terminated; other EIMs are unterminated. Since
the console is the hub in this configuration, it is
unterminated.

In Figure 5, the second EIM attached to the
console is the hub, and it is unterminated. The
VM96 console, and the EIMs at the end of each
leg must be terminated. Other EIMs are connected
together and unterminated.
