System Connection Options
The console and CM-MD64 should be connected using one of the system configurations shown over
the next few pages. The diagrams depict systems in redundant or non-redundant configurations.
IMPORTANT:
Best Practice when Designing a System
With coaxial cable it is best practice
NOT
to tape power cables to the coaxial cable. This could
lead to interference with the signal and result in unwanted audio artefacts, or in the worst case,
total loss of audio. It is highly recommended that
all coaxial cables be connected
to the
appropriate units
prior to powering
them on.
When designing a
system, it is extremely important to ensure that the
coaxial cable runs
do not
exceed 100m and fibre optic cables do not exceed 2km
.
When using
redundancy,
the optical and coaxial runs from the console to the unit (s) must not
exceed 2km or 100m respectively - and must be of
similar lengths
. The coaxial link cables
connecting the two units must not exceed 100m
When designing a non-redundant, redundant or daisy chain system, MegaCOMMS port A or B
from the console
MUST
be connected to
MegaCOMMS port A
- NOT port B - on the CM-MD64
and /or the stage rack. Any redundancy link cables must use ports B on both units.
