MATRIX-66
To distribute the audio signals (analog) and monitoring data,
each rack contains a Matrix-66 ethernet switch that combines
the control data and analog audio. Each Matrix-66 is equipped
with 6 “ALMA outputs” that are going to be used to send audio
and data to the groups of systems:
There exist two extra ethercon connectors, named ETH / CTRL,
at the right side of the panel, to connect the ALMA network be-
tween racks and ethernet switches /routers.
The number of units (LARAs /SARAs etc.) that can be “daisy
chained” in an array system should not exceed 6* (* this quan-
tity will be less when using power and signal distribution with
ECPK-20 cables. Note that for instance, the maximum number
of SARAs than can be fed from a single ECPK-20 is 4).
ARA series systems communicate using standard TCP/IP data
protocols, and so, like all typical network devices, need a set of
unique addresses to communicate with similar devices on the
network, and with the ALMA control software.
The users shall configure the systems defining properly these
two parameters:
- IP Address
- Subnet Mask
