Status LEDs
The following indicative LEDs are visible
from the front panel:
PSU OK (green)
Fan Fail (red)
Port 1 connected (yellow)
Port 1 active (green)
Port 2 connected (yellow)
Port 2 active (green)
Status (x8 red)
In addition, each input connector has
its own tricolour LED to indicate signal
presence. The incoming signal will cause
the LED to light green when the signal is
between -60dBFS and -38dBFS, amber
when between -38dBFS and -2dBFS,
and red when the signal clips at -2dBFS
or above.
Each output connector has a green LED
to indicate that there is a route established
to it from a console on the network.
Synchronization
Units are frequency synchronized using
synchronization packets received from the
Hydra network.
Diagnostics
The units support remote FPGA firmware
and software updates across the network
via the Ethernet ports. In addition, an
RS232 port is provided, such that system
diagnostics can be performed by a Calrec
approved engineer. Connection to the
port is via a front-mounted 9 pin D-Sub
connector.
IP Addresses
Calrec will supply each device in your
system with its own unique IP address,
which the system uses to identify each
network connection. On the front of each
Hydra I/O box, there is a label showing
the IP address. The secondary port will
use the address of the primary port + 100
decimal. For example:
Primary Port 192.168.0.050
Secondary Port 192.168.0.150
In an installation, the first 3 bytes (shown
HyDRA I/O bOxES
in red) are fixed. The 4th byte or least
significant byte is the part of the address
which is unique to that port on the device.
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.
If a Hydra I/O box needs to be swapped
out, the replacement unit must be
programmed with the correct IP address.
The 8-way switch on the rear of the unit
allows the least significant byte of the IP
address of the primary port to be set in
binary.
Surround Signals
It is not recommended that ports on
a modular Hydra I/O box should be
combined with ports on a fixed Hydra I/O
box to create a 5.1 surround signal.
