Wide Area Bulk Card
A Wide Area Bulk (WAB) card is inserted
into the console’s Processing rack.
The function of the WAB is to transfer
digital audio samples and control data
between the console and the Gigabit
interface unit.
Alpha and Sigma systems can have up
to 8 WAB interfaces; Omega and Zeta
systems can have up to 3.
128 inputs and outputs are carried
between each WAB card and the Gigabit
interface unit via 36 way SCSI-style
cabling up to 5 metres (16.5 feet) long.
During set up, the user can decide how
many of the system’s WAB interfaces
will be available for redundancy. The
bandwidth chosen for redundancy will
be reserved for use by the redundancy
system, and will not be used during normal
operation.
Control data is sent and received as
UDP (User Data Protocol) messages,
and consists of proprietary commands
for audio routing, parametric control and
network management.
Console PC
The console’s PC is connected to the
network via the Gigabit switch, such that
the user can monitor the devices on the
network.

COnsOle Hardware
If the console’s PC is not connected
to the network via the Gigabit switch,
some limitations apply - the front end
screens will not show port status or device
heartbeats, and the user will be unable to
edit the device names.
The console PC can also send and receive
UDP (User Data Protocol) messages to
and from the network.
Gigabit Interface Unit
The Gigabit interface unit provides the
console with a full duplex connection from
the WAB interface to the network via a
commercially available Gigabit switch.
Connection to the network is via a Gigabit
port on the rear of the unit. The second
Gigabit port on the unit is not used. The
unit runs at Gigabit speed all the time, and
may not be connected to switch ports that
run at lower speeds.
The unit is powered from the console’s
bulk power supply system, via a 24 V DC
input. A second connection is provided
for redundancy. The console’s bulk
power supply can also be supplied with
redundancy, further protecting the Hydra
system from failure.
An RS232 port is provided, such that
system diagnostics can be performed by a
Calrec-approved engineer. Connection to
the port is via a 9 pin D-Sub connector.
MAC Addresses
Any device on an Ethernet network
requires a Media Access Control (MAC)
address. The MAC address is a number
that uniquely identifies a device.
Each Ethernet frame has a source and
destination MAC address, length identifier
and CRC. A device on the network can
identify frames that are sent to it by
checking the destination MAC address
against its own MAC address. There is a
special address known as the broadcast
address in which all devices on the
network will receive the frame.
IP Addresses
Calrec will supply each device in your
system (including the console) with its
own unique IP address, which the system
uses to identify each network connection.
Where a device has two ports, each will
have a unique IP address. The 4th byte is
unique to the device.
The Hydra I/O boxes synchronize to
console with the lowest IP address on the
network.
For mobile installations, the 3rd byte
of the IP address will be unique to that
installation, such that it is possible for
different installations to connect their
networks together.
