Connection Information
AUDIO I/O CONNECTIONS
All audio inputs and outputs to/from
the console signal processing engine
are AoIP/AES67 based.
Audio Formats
AoIP I/O devices come in a variety of
formats and connector types including
MADI & SDI embedders/de-embedders
as well as standard AES digital and
analogue Mic & Line formats with a
variety of connector types. Please refer
to the '
AoIP I/O manual (926-293)
' for
full details on compatible AoIP I/O.
Power
All AoIP I/O devices are fitted with
dual power supplies & IEC mains input
connectors operating from 100-240VAC.
Both power inputs should preferably be
fed from two separate AC sources to
provide full redundancy. IEC 'Y' cords are
supplied to allow both inputs to be fed
from a single cable source in the event
that this is all that is available, ensuring
both PSU's can always be fed.
ID configuration
Each I/O box in a system needs to be
given a unique identity, this is determined
by setting IP addresses and Sub-Mask
values for Primary and Secondary
connections and by setting a DIP switch
accessible from the rear of a fixed format
box, or on the side of the controller card
within a modular I/O box to 0.
AoIP devices have their system IP
addresses factory pre-configured and
recorded prior to despatch.
Note: For use with Impulse or Type R
cores, the DIP switch address need to
be set to binary 0 which means all the
switches are set to the OFF position.
When ordering additional I/O, please
discuss with your sales person or Calrec
project engineer to select suitable AoIP
devices for the system it is to be used
with.
If fitting a replacement I/O box, settings
its DIP switches to Off and setting it's
IP addresses and Sub-Mask to be the
same as the unit it is replacing allows it
to function as a drop in replacement with
existing user memories and requiring no
further configuration (as long as the box
types are the same).
I/O boxes should be disconnected from
the network before changing their DIP
switches and reset or power cycled once
the DIP switch is set to ensure the new 0
value is active before reconnecting to the
network.
Do not change I/O box IP addresses
or add extra I/O to the system unless
you are confident it will not cause a
conflict on the network.
Fixed format I/O box IDs
The 8 way DIP switch is set as an 8 bit
binary representation with the left hand
switch used for the most significant bit,
and the right hand switch for the least
significant bit.
A switch in the down/off position
represents a binary 0 or set in the up/on
position represents a binary 1.
Each switch/binary bit equates to a
decimal value, starting at 1 for the least
significant bit. The remaining switches
are double the value of their less
significant neighbour, making the 8th
switch (the most significant bit) equate to
a decimal value of 128.
All fixed format I/O box ID switches are
orientated the same way, though some
boxes, use a different style switch with
more pronounced labelling. Ignore any
labels on the switch itself and always refer
to the Calrec labelling on the surrounding
panel which will show the most significant
bit switch on the left and the binary 1
position as up.
Address 2
Some I/O boxes are fitted with 2 banks of
DIP switches Address 1 and Address 2,
please note that Address 2 should also
all be set to the off position.
Modular I/O box ID setting
The ID for modular I/O boxes is set by a
DIP switch on the controller card and is
only accessible by removing the card.
ID switches on modular I/O controller
cards are orientated differently. Ignore
any labelling on the switch itself and refer
to the Calrec labelling printed on the
circuit board around the switch to clarify
its’ orientation. When viewing the card
from the side, the most significant bit is on
the left and the least significant bit on the
right. Pulling a switch towards you sets it
as a binary 1, away from you as a binary 0.
STANDARD SWITCH FOR AOIP SETTING
• The above diagram shows
how each switch relates to
a decimal value. The setting
shown in the example provides
a decimal value of 0.
