I/O PORT IDENTIFICATION
Default/NativeLabels
Each Hydra2 input and output port has
a default label beginning with the HID
number of the I/O box the port is located
in, followed by the number of the port
within that box. For example, a port in a
source list labelled 12-08 would be the
8th input in the I/O box with the HID of
12. The same port label in a destination
list would be the 8th output of the same
I/O box 12.
AES ports are numbered in stereo pairs
and as such have a L or R suffix to denote
the left and right legs of each pair. For
example 16-09R in a source list would be
the right leg of the 9th AES input pair to
I/O box 16.
MADI I/O boxes have two inputs and two
outputs, each of which contains 56 or 64
channels of audio (quantity set by front
panel button on the I/O box). Labels for
ports within a MADI stream contain an
additional number to identify the MADI
stream the port is in. For example, 31-2-
40 in a destination list would be channel
40 in I/O box 31’s second MADI output,
the middle number being used to identify
the MADI stream.
Modular I/O boxes can contain a mixture
of formats of I/O and their default port
labels contain a reference to the card
slot within the I/O box to further aid
identification. Modular I/O card slots are
labelled using letters rather than numbers.
Note that some card types take up more
than one slot space, such cards are
identified by their left most slot. Slot labels
are printed across the upper fixing rail and
each card has a small circular hole in the
upper left corner through which the slot
label can be seen. Slots are labelled in
alphabetic order however, the characters
F, I, O, Q, U and Y are omitted as these
could easily be miss-read and confused
with other letters or numbers. The central
slot in the card-frame is not included in
this labelling scheme as external I/O
cards are never fitted in this location. It
is instead labelled “H2 Interface” and is
always populated with a Hydra2 network
interface card. A source list port label of
12-K-04 would be the 4th input of the
card in slot K of the I/O box with the HID
12.
Modular SDI cards have two SDI inputs/
outputs per card. Each SDI stream can
have 16 channels of audio embedded into
it. An SDI port label of 12W1-8R would
be the 16th (and last) audio channel in
the first SDI stream of the card in slot W
of the I/O box with a HID of 12. 12W2-1L
would be the first audio channel of the
second SDI stream on the same card.
Each port’s format (Mic / Line / AES /
MADI / SDI etc) is also displayed and
color coded adjacent to its label to further
aid identification.
H2Oeditedcustomlabels
Default / native labels provide a unique
ID for each port and are very useful at an
engineering level, however, custom labels
may be more beneficial at an operational
level by referring to the device feeding or
being fed by the Hydra2 port, e.g. ‘Mic2’,
or ‘VT6’.
Port labels can be edited by H2O users.
H2O edited port labels are passed on
to all consoles on the same network,
replacing their defaults.
Consoleeditedcustomlabels
Port labels can also be edited at a
console level using the console’s Main
PC Application for Apollo and Artemis
consoles, or from the Touch Display
interface for Summa consoles. Console
edited labels are only visible on the
console from which they were entered,
other consoles and H2O will not display
them.
Ports that require the same label to be
visible from each console should be edited
using H2O to avoid having to name them
on each console.
PortDescription
If required, a description can be entered
against each port label in both H2O and
from each console’s PC/Touch Display
interface. As with labels, H2O-entered
data is visible to H2O and all consoles,
whilst console entered data is only visible
to the console it was entered on. The
description field allows for more text to be
entered against a port than can fit into a
label field.
