Installation Requirements
• To protect from lightning, mM requires one
grounding point on the coaxial cable and that
neither the frame nor covers of the mM Personal
Computer be used as the grounding point. Contact
~
a qualified technician for installation in compliance
with local electrical codes.
• The mM Personal Computer Cluster Adapter is
designed to interconnect up to 64 mM Personal
Computers using RG 59U coaxial cable.
• An Installation Manager is needed to plan, install,
and maintain the Cluster (A Cluster is all of the
Personal Computers, Cluster Adapters, and coaxial
wiring). As the Cluster is being installed, it is
necessary for the installation manager to develop a
Cluster Map. The Cluster Map can be a diagram or
listing of the Personal Computer location, the
adapter number assigned, the station (a station is a
Personal Computer on the Cluster) address, and the
order in which the stations are connected.
