User and Control Bit Pass-Through (A16.D16 and D64 Only)
To enable the pass-through of AES user and control bits the device must be set to PCM 32
encoding within Dante Controller. Changing the encoding setting is detailed in the Dante Controller
section of this guide.
N.B. When set to 32-bit encoding the audio remains 24-bit. The additional 8 bits are used totransport the user and control bits from the AES3 signals.

Hardware Connections
Mains Power Connections
The A16.D16, A32, D64 and GPIO 32 include redundant PSUs with IEC C14 inlets.
Either supply can individually power the unit. Ideally these should be connected toseparate power circuits to provide redundancy of incoming AC power.

Dante Connections
Network B ports are SFP cages which can be fittedwith either RJ45, single-mode or multi-mode LC fibre
connectors
Network A ports feature etherCON
ruggedised RJ45 connectors

Note: Network B functionality is currently notenabledA pair of LEDs per port provide
network information:
ACT flashes when there is
network activity
GB/SFP shows Ethernet/SFP
network status

The A16.D16, A32, D64 and GPIO 32 have two redundant sets of network connections. The
Network B port connectivity is currently not enabled, this requires an additional Dante card which iscurrently not available.

Audio and GPIO Connections
All audio and GPIO connections are via 25-pin D-type connectors.
See Appendix B for pinout information.

SSL Network I/O Controller
This section applies to the A16.D16, A32 and D64 only. GPIO 32 cannot be controlled from SSL
Network I/O Controller.

Installing Network I/O Controller
When SSL Network I/O is used without an SSL console, configuration and control is achieved using
the SSL Network I/O Controller PC application. This can be downloaded from the SSL website as partof the Network I/O Stagebox upgrade package or as a standalone installer.
Locate and run the Network I/O Controller installer and follow the on-screen prompts to install theapplication.
Application data is stored per Windows user account, allowing each user’s configuration of device
filtering, sorting and application window size to be retained.

Network Configuration - PC
Once Network I/O Controller is installed, connect the Windows PC to the same subnet as the
Network I/O. The SSL Network I/O Controller application uses the network adapters configured in
Dante Controller for communication. Before starting Network I/O Controller first open Dante
Controller and select the network adaptors connected to the Dante network. ‘Use shared Danteinterface’ must be selected to ensure all applications using the Dante network use the correct
adaptors. Subsequent changes to network settings may require Network I/O Controller to berestarted.

TCP/IP is used to communicate with the unit, so check Windows firewall settings if communications
are not working.
Set the computer to ‘Never Sleep’ to maintain communication.

Devices View
The Devices tab provides management of the I/O devices displayed in the Control View.
Device Filtering allows Network I/O device types to be hidden, both from the Control View and
the Control View Filtering and Sorting section. An example use case may be to hide allcompensated devices so that the Control View only shows the gain tracked signals, not thecompensated split feeds.
Control View Filtering and Sorting provides control of the order in which devices are displayed in
the Network View of the Control View, in addition to individual device filtering.
SHOW ALL clears the currently selected device
filters.
HIDE OFFLINE ensures only currently connected
devices are displayed, irrespective of device type.

Device Filtering is provided for all Network I/O device types available in Network
I/O Controller. These device types can be pre hidden, so they are not visible fromthis instance of the software when they are discovered. Device filtering hides theselected device types from the Control View and the below Control View
Filtering and Sorting table.

Column headings can be selected to affect the Sort Order of this table and importantly the order in which
devices are displayed in the Network View of the Control tab.
Selecting the heading for a column will set it as the ordering field and toggle between ascending ordescending. Sorting can be alpha-numeric by Name or Device Type, or numerically by IP address or Index(discovered order).

Ownership
Net I/O stageboxes can be controlled by SSL Live or System T consoles and the Network I/OController PC application. Separate Stagebox and Input ownership options are available to prevent
control conflicts between networked consoles and control computers sharing resources.

Press and hold Inputs Ownership to open the
Ownership menu:
Own All will assign all unowned inputs
Take All will assign all inputs including those
owned by another controller
Release All will release ownership of inputs
owned by the controller

The current owner is listed
in white.

Press and hold Stagebox Ownership to assign
or relinquish stagebox ownership.

Stagebox OwnershipStagebox ownership provides general ownership of the stagebox configuration, covering thefollowing parameters:Operating level
SRC state of AES inputs

A stagebox does not require an owner at all times, so can remain unowned if the above settings do
not need to be adjusted.

Input Ownership
Input ownership offers a level of protection to inputs: when an input is owned the input parameters
can only be modified by the device that owns it. Parameters covered by input ownership are:







Mic gainPhantom power
Mic/line switching
Pad
Input mute
SRC (sample rate conversion)

Note that multiple consoles can share the same input signal but only one device can control the
input parameters. Altering the input settings will affect all consoles using the input.
N.B. Ownership settings are stored on the A16.D16/A32/D64. The mute state is stored in volatilememory on the unit and all channels will reset to unmuted if the unit is repowered.

18

A16.D16, A32, D64 and GPIO 32 User Guide

Individual Input Ownership
One of three options will be displayed when an input is selected on a device, depending on thecurrent ownership state. These options are Own, Take and Release:
Inputs owned by another controller have apress and hold Take button. The current
owner is displayed in the Ownership windowof the Focus View.

Unowned inputs have a press
and hold Own button and show
there is no owner.

Inputs owned by this controller
have a press and hold Releasebutton and show this console as
the owner.

Only mic inputs owned by thisdevice have a fader cap and canbe controlled.

Console Routing and Input Ownership
When an SSL console makes routes from a stagebox mic input to a console channel, the console willautomatically become the owner of any unowned inputs. If an input is owned by a different
controller then routing will not automatically take ownership, Take ownership will need to be
performed if input control is required on this device. Note that the audio route will still be maderegardless of whether ownership is assigned.
When an SSL console unloads a showfile (as happens when a new showfile is loaded or the console
is powered down), routes are unmade. Unmaking routes for mic inputs automatically releases
ownership, leaving them unowned for the next use. Ownership status is stored on the device, for all
controllers on the distributed network to take account of.
If a stagebox is unreachable (e.g. it has been powered off) when the console showfile is unloaded
then the stagebox storage of ownership will persist. If the stagebox is to be used on the same
console (or set of consoles with the same showfiles) on next use, this persistence of ownership will
not matter. If the stagebox is to be used on a different console, ownership will need to be clearedusing Reset I/O Settings from console software or Net I/O Controller, or the hardware reset option
detailed in Status and Reset.
Ownership from Network I/O Controller is manually controlled. Network I/O Controller does not
manage Dante routing, this is done with Dante Controller.

GPO Ownership (A16.D16 and GPIO 32 Only)
The A16.D16 and GPIO 32 GPO connections also have ownership status. The available ownershipstates are identical to those for inputs.
N.B. GPIO 32 ownership is only controllable from System T consoles. GPIO 32 cannot be controlledfrom SSL Network I/O Controller.

Dante Controller

Refer to Audinate’s Dante Controller user guide for complete information on Dante Controller
software. The information below details the basics required to get started.
Clock sync, device naming, AES67 configuration and network management are all done within Dante
Controller.
Dante utilises the device name for routing. Each device must have a unique name – if a name isduplicated it will be appended with a number.

Network Config
Each device requires its own unique IP address. This may be automatically configured, provided by a
DHCP server or assigned manually. Unless shipped as part of a preconfigured system, Network I/Ounits are set to obtain an IP address automatically.
If the IP settings need to be changed to a fixed address – to match the network environment inwhich the unit is to be installed – this can be achieved using the Dante Controller application.
Remember that the computer’s network adapter configuration will also need to be updated to matchthe Network I/O.
The primary and secondary ports must not be connected to the same logical network. Ideally,
separate switching hardware should be provided for primary and secondary networks. Creating
VLANs on shared hardware is acceptable but does not provide the most robust redundancy.

Device Info
The Device Info tab shows an overview of all devices on the Dante network including name,product type, software version, IP address, link speed and status.
Device > Device View provides configuration and diagnostics for each device including Tx and Rx
subscription and signal status, software and firmware version information, network utilisation andreal-time latency measurement, as well as configuration of device name, sample rate, bit depth,
latency, IP address and AES67 parameters. The Network Config tab provides IP addressconfiguration options.
The device will resolve to a link-local address if it is set to obtain an IP address automatically and no
DHCP server is present. To access via link-local, set your computer to obtain an IP address
automatically, directly connect to the device’s primary port and wait for the link-local addresses toresolve. Link-local addresses for the Primary Dante interfaces obtain IP addresses in the169.254.xxx.xxx range, secondary Dante interfaces obtain addresses in the 172.31.xxx.xxx range.

Linking/Unlinking Networks A and B
Network B functionality is not yet enabled. The Network Config tab within Dante Controller Device
View allows for Networks A+B to be linked/unlinked, this currently has no functional effect on theunit.

User and Control Bit Pass-Through (A16.D16 and D64 Only)
To enable the pass-through of AES user and control bits thedevice must be set to 32-bit encoding (PCM 32). This is set
within the Encoding section of the Device Config tab.
