Computer system (via CAM)
Each computer system is connected
to the MC5 unit via a Computer
Access Module (CAM) and standard
category 5, 5e or 6 cabling. CAMs
are available in various formats to
suit differing computer system types
and their particular connector styles.
To connect a computer system
1 Ensure that power is disconnected from the MC5 unit and the system to be
connected.
(Note: If it is not possible to switch off devices prior to connection, then
a ‘Hot plug’ procedure is available – see the Hot plugging and mouse
restoration section for more details).
2 Locate the required CAM (there are ve types available) and attach its video,
keyboard and mouse (PS/2-style, USB or Sun) and optional audio connectors
to the relevant sockets on the computer system.

3 Lay a suitable length of category 5, 5e or 6 cabling between the computer
system and the MC5 unit. The maximum length of the cable can be up
to 50 metres (160 feet), however, bear in mind that the overall distance
between any remote user and any computer must not exceed 300 metres
(980 feet).
4 Attach the connector of the cable
run to the socket of the CAM.
5 At the other end of the cable run, attach the cable connector to one of the
sockets labelled COMPUTER CONNECTIONS on the rear panel of the MC5 unit.

Note: CAMs derive power from the

keyboard connector, USB or SUN connector.
6 Where necessary use the in-built video compensation feature of the MC5
unit to eliminate any effects caused by the cable run. See Computer video
compensation for details.

Note: Each CAM is
specically shaped so
that it can be secured
using a cable tie around
its middle. In this way,
two CAMs can also be
neatly joined together,
back-to-back.
