38 HYDRA2
Operator Manual
Using H20
SW-P-08 CONFIGURATION
Input to output cross-point matrix
routing of Hydra2 ports and Hydra
Patchbays can be performed remotely
from 3rd party equipment supporting
the SW-P-08 protocol.
The SW-P-08 connection is made to
the router card in the processing rack
configured as the Master Router (the
same processing rack as the H2O
connection, but to the router card rather
than the Control Processor). Please refer
to the Hydra2 installation manual for
more detail on the SW-P-08 protocol and
connection.
The Hydra2 I/O ports that are to be used
with SW-P-08 need to be given matrix,
level and ID information. In the I/O Box
& Port Labels screen, select the SW-P-
08 Mapping tab at the top of the port
labelling area to bring up these fields
for each I/O port on a box by box basis.
To ensure any desired changes are not
lost, click on APPLY CHANGES before
changing the screen or viewing a different
I/O box port list.
SW-P-08 Matrix, Level and IDs can also
be given to Hydra patchbays, allowing the
remote control system to patch console
DSP outputs to physical output ports as
well as change which sources are feeding
console DSP inputs.
As well as setting values for the I/O
ports intended for remote control, SW-
P-08 values also need to be assigned
for ‘Digital Silence’ and ‘Source out
of Range’. Manufacturers refer to
these two instances differently and so
documentation for specific 3rd party
devices should be consulted. ‘Digital
Silence’ refers to unused patches, where
black or silent signals are patched to
unused destinations. ‘Source out of
Range’ refers to instances when a source
that is unknown to the 3rd party device
is patched to a destination. These values
are entered from the Control Protocols
IO BOX & PORT LABELS, SW-P-08 MAPPING SCREEN
CONTROL PROTOCOLS SCREEN
screen. Again, ensure APPLY CHANGES
is clicked before navigating away from this
screen.
Within the IO Box & Port Labels screen,
and the Control Protocols screen, unsaved
changes are highlighted with a blue
background. If invalid or duplicated data
is entered against a source or destination,
the row will be highlighted red and
the APPLY CHANGES button will be
greyed out preventing the changes being
submitted.
The SW-P-08 data entered should
match that of the 3rd party controller’s
configuration* SW-P-08 and port label
data can be imported to and exported
from H2O as CSV files to reduce the
amount of manual data entry. Please see
the following section for guidance on CSV
file import / export.
*The exact format of SW-P-08 mapping data
may vary from system to system. Calrec uses a
“1 based” count - the first addresses in each field
being 1. Some systems start the count from 0,
and therefore an offset of 1 would be required
between the two sets of mapping data.
The Grass Valley Jupiter system counts
from 0 but also uses its physical level
numbers rather than SW-P-08 values in
its config. When entering data into H2O,
the SW-P-08 matrix value is the Grass
Valley physical layer value divided by 16
(rounded down to the nearest integer).
The SW-P-08 level is the remainder /
modulo of the Grass Valley physical layer
divided by 16. A 1 then needs to be
added to both values to cater for the count
offset:
For example:
A Grass Valley physical layer of 100 (decimal)
gives a Calrec SW-P-08 matrix value of 7
(100/16 = 6.25, rounded down = 6, +1=7), and
a Calrec SW-P-08 level value of 5 (100 mod 16 /
0.25 x 16 =4, +1=5)
