Io IP Transport, Capture, Display v16.2r1 5 www.aja.com
Chapter 1 – Introduction
Overview
Io IP is a powerful yet portable video and audio I/O device for professional IP
based workflows. As part of AJA’s industry-leading Io line of Thunderbolt capture
and playback devices, Io IP works seamlessly with a large number of popular
creative software applications, including out-of-the-box support for Adobe
Premiere Pro, Apple FCP, and Avid Media Composer.
Designed as a flexible platform with support for SMPTE ST 2022-6 and ST 2110
uncompressed IP video/audio, Io IP brings the highest quality 2K, HD, and SD
video and audio over IP to computers running Mac or Windows Operating
Systems. Io IP can also support 4K/UltraHD p60 (2SI) capture or playback, via
SMPTE ST 2110-23.
Io IP is also supported through the very same SDK as the rest of the KONA family,
making it straight forward for developers to make the transition to Video over IP.
Io IP Features
Io IP is designed as a platform with the flexibility to support different
uncompressed IP requirements at the highest quality for 4K/UltraHD, 2K/HD, SD
video and audio over IP for host systems running Mac or Windows Operating
Systems. By loading the appropriate firmware (aka bitfile), Io IP is able to change
its 'personality' to fit the required workflow as follows.
s2022 firmware supports Rx and Tx for:
• YCbCr 4:2:2 10-bit for 2K/HD and SD.
• Supports 2022-7 for redundant Tx.
s2110 firmware supports Rx and Tx for:
• YCbCr 4:2:2 10-bit for 4K/UltraHD, 2K/HD and SD.
• Supports 2022-7 for redundant Tx up to 2K/HD.
• Supports 2110-23 can be used for 4K/UltraHD p60 (2SI) capture or playback.
s2110-RGB firmware supports Tx for:
• RGB 4:4:4 12-bit for 2K/HD post production rates (23, 24, 25)
• Supports 2022-7 for redundant Tx up to 2K/HD.
NOTE: NDI is supported on Io IP in the same way as it is supported on KONA4, courtesy
of running Newtek Connect.

Io IP Transport, Capture, Display v16.2r1 6 www.aja.com
Video Formats
See "Appendix A Specifications" on page 71 for a listing of supported video
formats.
Physical Connection for IP Video
• 2 x 10 GigE Ethernet SFP+ Cages - SFP+ modules (not included).
See "Appendix A Specifications" on page 71 for a list of SFPs tested by AJA.
Inputs and Outputs
• Io IP ships by default with s2110 rmware for ST 2110 operation.
• For ST 2022-7 operation, a second SFP is used for redundant transport of the
other SFP's signals.
• When supporting 4K with Io IP via ST 2110-23, note that both SFPs are being
used in one direction, either input or output.
• Io IP HDMI output supports HDR signaling and monitoring for HDR10 and
HLG. HLG support is application dependent. Check with your software
manufacturer for compatibility.
Digital Audio Input
• 16-Channel embedded audio
Digital Audio Output
• 16-Channel embedded audio, 16- and 24-bit per channel, 48 kHz sample rate,
synchronous
• 8-Channel HDMI embedded audio, 48 kHz sample rate, synchronous
Signal Timing
• 1x BNC assignable to reference video or LTC input
• Relevant to SMPTE ST 2022-6/7 workows only
• Not used for SMPTE ST 2110 workows
Internal HD/SD Hardware Downstream Keyer
Io IP provides a powerful hardware keyer that can place graphic files with an
alpha channel over video in a selectable matte or the contents of the device’s
framebuffer from a software application. Key a bug or text over picture and avoid
what might normally be a lengthy software render. Also, working with these
software applications, you can key video that has an alpha-channel over video
input or a matte.
NMOS
NMOS is a mechanism for providing discovery, registration and control in ST
2110 environments. A separate application, “AJA NMOS”, supports automatic
discovery of IP devices on the network, using an app (daemon) that operates in
the background with minimal user configuration. The first AJA device accessed by
the computer running the daemon can be discovered and subject to control by
an external NMOS network control application. NMOS uses the IP address of the
host machine for communications.

Io IP Transport, Capture, Display v16.2r1 7 www.aja.com
Generally, NMOS works as follows:
• When Io IP starts up, the NMOS app actively scans the network for an NMOS
registry using MDNS/DNS. If found, the NMOS registry is informed who the
Io IP device is, and its capabilities.
• If during startup the NMOS registry is not found, the NMOS app continues to
announce Io IP's presence via MDNS so that it can later be discovered, and
then after discovery, it can be manually registered in the network control
application.
During installation AJA NMOS can be set to launch upon reboot or power up
(see "NMOS Installation" on page 16). The application's function is to make the
Io IP discoverable and controllable by various IP routing and control systems
(e.g. Imagine, LAWO, Sony). Discovery, registration and network control are not
part of SMPTE ST 2110 but are specified by JT-NM NMOS or Network Media Open
Specification. Two parts of this standard are IS-04 Discovery and Registration and
IS-05 Connection Management.
When the tray icon is clicked (on the Mac or right click on Windows), the AJA
NMOS application offers a number of options:
• View Log - toggles opening or closing of the log window
• Stop/Start Service - allows the NMOS service to be stopped and restarted
without quitting the application
• Enable/Disable Debug Log - enables or disables the generation of debug
output to the AjaLogger and the log window
• Enable/Disable DNS Debug - enables or disables additional DNS debug
information (independent of Debug Log setting)
• Enable/Disable Verbose Debug - enables or disables additional debug
information if the Debug Log setting is enabled
• Select Interface - NMOS only uses one interface to access the registry. If there
is only one interface, then that is not a problem. If there is more than one, then
if auto is selected, it will automatically choose one based on whether it sees
any mDNS messages on one of the interfaces. Otherwise, the interface can be
selected.
• Set Registry IP - allows the registry ip address and port to be set manually.
• Quit - causes the NMOS application to exit
AJA Software & Utilities
Io IP operates with AJA's Desktop software package, developed for powerful
integrated video/audio capture, editing, and production with a variety of 3rd-
party software. AJA software is distributed as a unified package which includes all
the software, firmware, plug-ins, and utility programs for the Io IP, as well as AJA’s
Io, KONA, and T-TAP products.
Two retail packages are available, one for Mac and one for Windows.
Mac and Windows Packages
These packages include:
Firmware
Firmware, otherwise referred to as a bit file or the Io IP's 'personality', refers to
very low level code that defines the capabilities of the hardware. It is important
to always update to the firmware recommended following install of new, or older
versions of software.

Io IP Transport, Capture, Display v16.2r1 8 www.aja.com
Drivers
AJA device drivers for the host system OS provide tightly integrated hardware/
software operation.
AJA Control Panel
The Control Panel provides:
• Source selection and control of your AJA hardware
• A block diagram to show visually what routing and processing is being
performed
AJA Control Room
Control Room is a cross-platform software application for ingest, playback and
output with AJA products.
AJA System Test
AJA System Test provides accurate and detailed evaluations of drive and system
performance statistics, allowing you to measure the capabilities of your system
for recording and playing back various resolutions and codecs. The application
includes:
• System Disk Test
• AJA Device Test
• System Report
The application tests Read and Write, Capture and Playback speeds in both
Megabytes per second and Frames per second. The disk speed tests differ from
standard disk I/O performance applications in that they specifically test the
system under conditions typically encountered with video capture, playback, and
editing.
NOTE: Theoretically the best test (or simulation) is to fill your storage disk to 80% and
then test capture at the highest data rate you will use.
3rd-Party Plug-ins
Plugins for popular 3rd-party Professional Video Applications from Adobe, Avid,
Apple, OBS and Telestream.
NMOS App
Available for automatic discovery of IP devices.
Network Requirements
For uncompressed workflows (SMPTE ST 2022-6 and SMPTE ST 2110) a 10GbE
switch is required.
For SMPTE ST 2110 specifically, a PTP clock source must also be deployed and the
switch must therefore also be PTP aware.
In all cases the switch used must be both managed (configurable) and IGMP
aware.
SFPs are not included with the purchase of Io IP. Recommended SFPs are listed in
"Specifications" on page 71.

Io IP Transport, Capture, Display v16.2r1 9 www.aja.com
System Requirements
AJA Video recommends that your system meet minimum hardware and software
requirements to achieve a satisfactory level of performance. Updates to system
requirements are subject to change.
NOTE: See Software Vendor system requirements for GPU recommendations and
additional hardware requirements and recommendations.
See the Io IP Release Notes, available on the AJA website and also installed with
the software package, for detailed system requirements including OS, CPU, RAM,
and GPU.
For IP installations specifically, AJA recommends:
• IP infrastructure with adequate bandwidth to sustain the capture and
playback of the material you expect to be working with across the number of
systems that are active at any given time
• For multi-seat installations, IP infrastructure that is comprised of fully
managed switches and is in turn supported by a team of qualied network
administrators
• For SMPTE ST 2022-7 implementations, two entirely independent network
infrastructures are required for true redundancy
NOTE: For large scale installations with shared storage, IP, or for very high performance
requirements, AJA recommends consultation with an experienced a system
integrator. A consultant will be able to assist with many important variables.
Disk Storage Methods
To ensure performance and quality, the disk storage system used with
the workstation must be able to meet the demands of storing real-time
uncompressed media. At the very minimum, the disk storage system must be
able to provide and maintain a consistent transfer rate from the workstation to
disk (read/write). There are a variety of system configurations and peripherals that
can provide this level of performance.
For more on disk storage performance see "AJA System Test" on page 8.
About Io IP Modal Operation

supported on the output. HDMI Output also supports HDR (HDR10 and HLG).
Reference Video
When in SMPTE 2022-6 mode, Io IP can lock to reference analog or tri-level input,
or the incoming SMPTE 2022-6 stream.
For analog reference, a single BNC on the Io IP endplate allows you to synchronize
Io IP outputs to your house analog or tri-level reference video signal (or black
burst). If you have a sync generator or central piece of video equipment to use
for synchronizing other video equipment in your studio, connect its output here.

Io IP Transport, Capture, Display v16.2r1 14 www.aja.com
When Io IP outputs video in SMPTE 2022-6 mode, it locks to this reference signal.
When connecting a reference video source, the locking signal should be the same
format as the Primary format selected in Io IP software. It is possible in some
circumstances to use an alternate format video signal if the basic frame rate is
compatible.
Io IP can also lock to an incoming SMPTE 2022-6 signal, or it can free run.
Balanced Analog Audio Input and Output
A 25-pin connector provides 8-channel balanced analog audio, 24-bit 48kHz
sample rate D/A and A/D, for use with an industry standard 8x XLR on DB-25
breakout cable (cable not included). The eight analog audio channels can be
configured four different ways:
• Ch 1-8 Output
• Ch 1-4 Input and Ch 5-8 Output (default setting)
• Ch 1-4 Output and Ch 5-8 Input
• Ch 1-8 Input
12V Power Connector
A standard 4-pin XLR type connector is provided for either battery or line source
power using the supplied AC power adapter.

your system use the packaging materials and box for safe shipment.
Installing Io IP Software
NOTE: If your computer has previously had another video capture or multimedia device
installed, ensure you uninstall any related software before installing Io IP. This will
prevent any hardware or software conflicts.

Io IP Transport, Capture, Display v16.2r1 16 www.aja.com
Before installing the AJA Desktop Software package, ensure that your capture/
editing application is installed as detailed in its user documentation. You cannot
use the AJA Desktop Software package with a third-party application until the
application has been installed and run at least once on your workstation. Next,
install the AJA Desktop Software package. If at a later date you add any Io IP
supported applications that require drivers, you must run the AJA install program
again to install them.
NOTE: Always uninstall the previous version of the AJA Desktop Software package
before updating your Io IP.
NMOS Installation
You can choose how to install AJA NMOS with the AJA Software Installer package.
The default Complete (PC) or Standard (macOS) installation choice will require
you to manually launch the AJA NMOS application when you want to use NMOS.
With the alternative Custom (PC) or Customize (macOS) installation choice you
can check the AJA NMOS Service box, which will make AJA NMOS automatically
launch on startup. In either case, NMOS operation will require your AJA device to
be connected to a network that has a running NMOS control application.
macOS Installations
macOS High Sierra (10.13), macOS Mojave (10.14), macOS Catalina (10.15), macOS
Big Sur (11.x) and macOS Monterey (12.x) all have security requirements that may
present dialogs during installation. Please refer to the Release Notes for guidance
Io IP Firmware Installation
IMPORTANT: The firmware installed in your Io IP should match the version of the AJA
software package. If a mis-match is present, the Io IP may not work and a "Not
Valid, device needs firmware update" message will be displayed. Always update
the firmware of your Io IP when you install an AJA software package. In addition,
a restart is required after changing firmware to enable NMOS registration.
Types of Io IP Firmware
AJA Desktop Software can provide the Io IP with three different personalities, or
modes of operation.
• s2022
• s2110
• s2110 - RG B
Switching between these different Io IP operating modes requires loading the
appropriate firmware bitfile and then resetting the Io IP.
Cabling the System
See "Rear Panel Connectors" on page 13.
Io IP Cable Connections
For 2022-6 and 2022-7 operation, 10GbE infrastructure can beconnected
with either a short (3 feet) Direct Attached cable, or optical fiber cable with
appropriate SFPs.

SFP Module Connections
For SMPTE 2022-6 / SMPTE 2022-7 operation (s2022), modules inserted into the
two SFP+ cages can be used to connect two separate 10 Gigabit Ethernet Links.
With AJA Desktop Drivers, the SFP 1 and 2 modules are configured using AJA
Control Panel software, using the Input, Output, and Network Settings tabs. In
most cases, only SFP 1 will be used, providing up to two total streams of SD or
HD video, each with 16 audio channels and metadata, for simultaneous input or
output, i.e. when using SMPTE 2022-6. Both links are bi-directional (one In, one
Out). When using SMPTE ST 2022-7, the Lower SFP carries a duplicate of the Upper
SFP data.
For a list of SFP+ modules tested by AJA, see "Appendix A Specifications" on page
71.
Unicast and Multicast Support
Io IP supports both unicast and multicast operation. Unicast operation is point to
point, from one sender to one receiver. Multicast operation is from one sender to
possibly multiple receivers. In both cases, the sender transmits information to a
location (IP address) on the network, and receivers access that information over
the network using that location IP address. Compatible IP addresses are required
for each type of operation. These network settings filter the IP addresses so the
information is sent successfully to the desired receiver(s).

Io IP Transport, Capture, Display v16.2r1 18 www.aja.com
IMPORTANT: Proper network configuration settings vary, depending on your particular
network environment. Because the process can be complicated, you should
always consult with your facility's IP or Networking Engineering department
before configuring Io IP network settings.
Listed below are example sets of compatible IP addresses that could be used in
an isolated network to test Io IP network operation.

AJA Control Panel Overview
The AJA Control Panel is a software application that provides a simple visual
showing how the Io IP hardware is currently configured and allows you to make
changes. You can change signal input and output parameters and define the
video processing that will be performed.
The AJA software installer automatically installs the Control Panel application on
your computer.

Io IP Transport, Capture, Display v16.2r1 20 www.aja.com
AJA Control Panel Operating Modes
AJA Control Panel has two fundamental operating modes.
Playback Mode - Used for playing back video files from the computer, usually
with a non-linear editing application (NLE) or AJA Control Room, through the
Io IP’s video/audio outputs for viewing and/or external recording.
Capture Mode - Used for capturing video/audio signals that are coming into the
Io IP from an external source to create video files on the computer using AJA
Control Room or an NLE, or just for display on the Io IP outputs. This mode is
also used for stand-alone video display or conversion when Control Panel is
being used without an external controlling application.
AJA Control Panel User Interface
The AJA Control Panel user interface includes a visual block diagram of the unit’s
current configuration. The current status, input and output settings, and many
other details are depicted in the color-coded block diagram. Below this block
diagram are various controls for changing operating parameters, which will vary
depending on which function screen has been selected.
The left side of the AJA Control Panel provides a navigation list of available
function screens. Clicking on a link (or alternatively, a related element in the block
diagram) displays a function screen corresponding to that topic.
NOTE: Although Io IP is sending and receiving video over IP, once that data is decoded
to memory it is governed by the same video menus used for SDI and HDMI based
AJA I/O solutions.
