Cascading multiple units

The MC5 (IP) units support up to
twenty four directly connected
computer systems, however, this
is by no means the limit. Thanks
to an intelligent communication
system, called

Port Direct

, many

more computer systems can be
controlled by connecting other
MC5 units. The combination
of units can be arranged up to
three levels deep forming a tree,
or cascade arrangement, with
computer systems situated at any
level within that cascade tree.
The maximum number of
computer systems that can be
controlled within a cascade
installation depends upon the
MC5 unit placed at the top
level. If the top level unit is a
non-IP version, a maximum
of 512 computer systems can
be controlled. However, if the
top level unit is an MC5-IP, the
maximum number of computers
drops to 128. This is due to the
extra burden placed on the unit’s
memory of administering global
(IP) users.

The cascade tree

The diagram shows how multiple MC5 units can be cascaded up
to three levels. Computer systems can be connected at any level.
Up to four users (local, remote or global) can simultaneously access
computer systems situated around the cascade tree.
