Status and Reset
These reset buttons have the same functionality as the front-facing RESET A and RESET B user
buttons.
Device Reset
Performing a device reset will clear the SSL device settings. This includes ownership, input and GPIO
states. This does not clear Dante Brooklyn card settings.
Brooklyn Reset
Resetting the Dante Brooklyn card to default settings is performed from Dante Controller. Under the
‘Device Config’ tab for a device select ‘Clear Config’. This clears the device name, channel labels, IP
address settings, sample rate, latency and existing audio routes. This does not clear SSL Ownership
settings.

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 to
transport the user and control bits from the AES3 signals.

Hardware Connections
Mains Power Connections
The A16.D16, A32 and D64 include redundant PSUs with IEC C14 inlets. Either
supply can individually power the unit. Ideally these should be connected to separate
power circuits to provide redundancy of incoming AC power.


Dante Connections

The A16.D16, A32 and D64 have two redundant sets of network connections. The Network B port
connectivity is currently not enabled, this requires an additional Dante card which is currently 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
Installing Network I/O Controller
When an A16.D16, A32 or D64 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 part of 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 the
application.
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 Dante
interface’ 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 be
restarted.
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.
Network Configuration - Device
Unless shipped as part of a preconfigured system, Network I/O units 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 in
which 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 match
the Network I/O.
For additional information see the Dante Controller section.

GPIO (A16.D16 Only)
The A16.D16 is equipped with 4 GP input and 4 GP output circuits. Inputs are opto-isolated voltage
triggered and output closures are via DIL relay.
See Appendix B for connector pinout and contact ratings.
Setup

A16.D16, A32 and D64 User Guide Contents
Ownership
Ownership offers a level of protection to inputs: when an input is owned by a console the input
parameters can only be modified by the device that owns it. This prevents control conflicts between
networked consoles and control computers sharing resources. Parameters covered by ownership are:
●Mic gain
●Mic/line switching
●Pad
●Input mute
●SRC
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.
Any System T console, SSL Live console or instance of the SSL Network I/O Controller PC application
can control ownership. There are three levels of ownership:
●Stagebox ownership: control A16.D16/A32/D64 setup information only
●Input ownership: control input parameters only
●Input x ownership: control of input parameters on a per input basis
N.B. Ownership settings are stored on the A16.D16/A32/D64. The mute state is stored in volatile
memory on the unit and all channels will reset to unmuted if the unit is repowered.
Stagebox and Input Ownership

 
Page 14 of 26

A16.D16, A32 and D64 User Guide Contents
Individual Input Ownership
One of three options will be displayed when an input is selected on a device, depending on the
current ownership state. These options are Own , Take and Release :
If an input is not owned and it is routed to an SSL console, the console will automatically take
ownership. 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.
Ownership from Network I/O Controller is manually controlled.
Note that the audio route will still be made regardless of whether ownership is assigned.
GPO Ownership (A16.D16 Only)
The four A16.D16 GPO connections also have ownership status. The available ownership states are
identical to those for inputs.

A16.D16, A32 and D64 User Guide Contents
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 is
duplicated 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. 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 and
real-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 address
configuration 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 to
resolve. Link-local addresses for the Primary Dante interfaces obtain IP addresses in the
169.254.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 the
unit.
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 32-bit encoding ( PCM 32 ). This is set
within the Encoding section of the Device Config tab.
