HD/SD SDI Input and Output
BNC connectors are provided on Io Express for one HD/SD-SDI input and one
HD/SD-SDI output. The input and output support video and embedded 24-bit
digital audio. Use SDI wherever possible for the best quality 10-bit uncompressed
video input, capture and output. If peripheral equipment has a variety of inputs/
outputs, look to see if it has SDI I/O, and use it where possible. Most high-end
professional broadcast equipment supports SDI (VTRs, cameras, media storage
servers, etc.).
HDMI Input and Output
Two HDMI connectors on the Io Express provide input and output of HDMI
compatible video and multi-channel embedded audio (8 channels). HDMI v1.3a
capability at 30 bits per pixel allows full support of the latest 10-bit monitors.
HDCP is not supported on either input or output. Io Express HDMI output does
not have HDCP, and input sources having HDCP are not supported. The HDMI
input is designed to support long cable runs—up to 100 ft. when using 22 or
24AWG HDMI cable, or up to 50 ft. using 28 or 30AWG HDMI cable. The HDMI
output supports standard HDMI cables only. The AJA Control Panel allows
selection and adjustment of some HDMI parameters.
Analog 2-Channel Unbalanced Audio Output
Io Express provides two analog output connectors, one for each channel. These
connectors are RCA-style phono jacks.
A 1/8 inch TRS headphone jack, with volume control, is also available on the front
panel.
RS422 Machine Control
A female DE-9 connector on Io Express provides connection for VTRs, camcorders,
disk media servers, and other devices using RS422 SMPTE (Sony) protocol.
(Connector pinout is listed in "Appendix A Specifications" .)
Component Video Output (with Composite and Y/C)
Io Express features a group of 3 BNC connectors for output of component,
composite and Y/C functions. The signals are labeled on the BNC connectors on
the rear panel of Io Express.
Component Video, or YPbPr, has been given several names over time. YUV, Y/RY/B-Y, and YCbCr, are just some examples. Although these various formats have
some differences in levels, they are all basically the same. Io Express uses the
modern YPbPr terminology exclusively. Io Express supports three different types
of YPbPr: SMPTE/EBU N10, Betacam (NTSC), and Betacam (NTSC Japan). These
three formats differ in level only and are configured in the Mac System via the Io
Express Control Panel.
Reference Video and LTC Input
Two BNC connectors on Io Express provide reference Input and Output. The
Reference Video input can also be used for LTC input. The selection of Reference
(sync) or LTC is set using the Io Express Control Panel.
In Video Pass-through mode, these connectors are effectively loop-through.
Supplying reference signal to the Reference input allows you to synchronize Io
Express outputs to your house analog reference video signal (or black burst).
If you have a sync generator or central piece of video equipment to use for
Io Express Capture, Display, Convert v14.07
www.aja.com

synchronizing other video equipment in your studio, then connect its analog
composite output here. When Io Express outputs video, it uses this reference
signal for locking. When connecting a reference video source, the locking signal
should be the same format as the Primary format selected in the Io Express
Control Panel. It is possible in some circumstances to use an alternate format
video signal as long as the basic frame rate is compatible.
In This Manual
Chapter 1 gives general Io Express information and lists product features and
system requirements.
Chapter 2 provides instructions for installing and configuring Io Express.
Chapter 3 discusses the operation of Io Express when used with AJA Control Panel
and third-party applications.
Appendix A presents a list of Io Express technical specifications.

Chapter 2 – Installation
What’s In The Box?
As you unpack the shipping box(es), carefully examine the contents. Ensure you
received everything and that nothing was damaged during shipment. If you find
any damage, immediately notify the shipping service and supply them with a
complete description of the damage. AJA will repair or replace damaged items.
If you find shipping damage, contact your AJA dealer or distributor for details on
how to have your Io Express repaired or replaced. Save packing materials and the
shipping box. If you ever require service or move your system use the packaging
materials and box for safe shipment.
When you unpack your AJA Io Express, you’ll find the following components:
• Io Express
• PCIe Card
• PCIe Tether Cable
Installation
Overview
The installation and set up of Io Express is very simple. The steps of installation
and configuration are discussed here and summarized as follows:
1. Unpack the shipping box.
2. If not previously installed on your Mac Pro or Windows workstation, ensure
that appropriate application software, such as Apple’s Final Cut Pro or
Adobe Premiere Pro, is installed as detailed in its user documentation.
Editing software must be installed and have been run at least once prior to
installing Io Express software.
3. Download and install the latest Io Express software from:
http://www.aja.com/en/support/io/mac/io-express/
4. Install the Io Express PCIe card in your Mac or PC (see "Connecting To Your
Computer" below).
5. Cable the system audio and video sources, VTR, audio monitor, and video
monitor (see "Cabling the System" on page 10).
Connecting To Your Computer
CAUTION: Always have power off when connecting any device to the PCIe bus.
1. With your computer off, install the PCIe card into the computer or external
PCIe chassis.
NOTE: Refer to your PC manufacturer’s documentation for installing a PCIe card.
2. Connect the PCIe tether cable between the Io Express PCIe port and the
PCIe card.

www.aja.com

4. Connect the Power Supply to AC power and turn on Io Express using the
front power switch.
NOTE: For correct performance, always power up Io Express before starting your
computer and power down your computer before powering down Io Express.
Cabling the System
The following figure shows a typical interconnection for a system with digital A/V
sources. Your system may differ depending on VTRs, audio monitoring, and video
monitoring.
1. If desired, connect your house reference sync to the Io Express Ref/LTC
connector (BNC). The second Io Express Ref Loop connector (if used in Pass
through mode) can be connected to the VTR or terminated with a 75-ohm
terminator. If instead you are using LTC timecode input, connect to the Ref/
LTC input.
2. Connect an HDMI Video Monitor to the Io Express HDMI Out connector. Or
instead, use the Component Analog Video Out BNC connectors to go to an
analog monitor.
3. Connect a 9-pin DE-9 machine control cable between your VTR’s RS422
control port and the Io Express RS-422 machine control connector.
4. Connect two SDI cables between Io Express and your digital VTR (Digital
Betacam etc.): one from Io Express SDI In to the VTR SDI Out, and one from
Io Express SDI Out to the VTR SDI In. The Io Express SDI connections have
embedded audio so the VTR must be configured accordingly.
5. Use the two RCA-style unbalanced stereo output jacks for audio monitoring
output.

Chapter 3 – Operation
AJA Control Panel Overview
The AJA Control Panel is a software application that provides a simple visual
showing how the Io Express 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. You’ll find the AJA Control Panel application in your Applications
folder.
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.

Screen Navigation Shortcuts
Various Control Panel screen navigation shortcuts are available.
• Click on an icon to call up its related parameters screen. For example, clicking
on an Input triangle brings up the Input Select screen.
• Right-click or Control-click on an icon to see context-sensitive information and
direct select choices (Figure 4).
Figure 4. Context Sensitive Menu
• Left or right-clicking on some items opens a direct selection list. Hovering the
cursor over these items colors them yellow. These items include:
• Format and frame rate shown above the framebuffer
• Pixel format and Follow Input shown in the framebuffer
• Current mode (Playback or Capture) shown below the framebuffer
• Genlock
Playback and Capture Modes
The current AJA device operating mode is shown below the framebuffer. When
no external application is in control, selecting Input Passthrough in the Control
screen enables Capture Mode. Selecting Test Pattern or Hold Last App enables
Playback Mode.
When an external application is in control, it may change the operating mode
depending on the function that application is performing. For example, in Adobe
Premier Pro, selecting the Capture window will change the AJA Control Panel
mode to Capture Mode.
Block Diagram Area
The top block diagram area of the Control Panel screen is a visual representation
of the processing, if any, that’s currently occurring, including inputs/outputs,
reference source, and system status. Lines between inputs, the framebuffer, and
outputs, show a video path. Where there are no lines, there is no connection; this
can be because an input or output isn’t selected in the Input Select menu. The
lines will also show whether the outputs are video or video + key.
You can click any of the function screen selection links in the left column to view
its current settings or click on an icon to call up its related settings screen. You can
also right-click or Control-click to see context-sensitive information and choices
(Figure 5).
Figure 5. Context Sensitive Menu
Color Meanings
All items in the AJA Control Panel block diagram are color-coded to show what is
happening in real time. This applies to both icons and text. These colors indicate:
Blue - Video is same format as the Primary Format (framebuffer)
Io Express Capture, Display, Convert v14.013www.aja.com

Green - Indicates that Io Express is performing an active change to the video
making it different from the Primary Format (e.g., down-conversion).
Yellow - Reference video (black burst or other reference source)
Red - The selected operation cannot be performed
Input/Output Icons
The input and output icons are triangles that together with their color show all
the input and outputs and their status (selected, not selected, input present or
not, format, etc.). A complete video path is shown when inputs and outputs are
connected with lines going to/from the framebuffer.
Figure 6. Input/Output Icons
Primary Format
The Primary Format is the media format written to disk and used in your project.
This is the format that the framebuffer will use and is shown in the Control Panel
using the color blue. It is the format that the third-party application software will
either receive from the AJA hardware, or is sending to the hardware. All icons in
blue are the same as the Primary Format used by the framebuffer. Also any text
descriptions in the block diagram that appear in blue indicate that something is
in the primary format. For example:
• If the input and output icons are blue, you know that the same format is used
throughout the video path. No format conversion is being performed.
• If the input or output icon colors differ (blue input and green output icons for
example), you know that a format conversion is being performed.
Secondary Format
Any format other than the currently selected Primary Format, is a secondary
format. This means that either the Inputs or Outputs are somehow different from
the framebuffer’s assigned format, the Primary Format. A conversion is readily
apparent because of the color change from blue.
NOTE: In some cases the application you use with the Io Express will automatically set
the Primary Format, overriding the user’s selected primary format in the AJA
Control Panel.
Format Conversion
Format function screen conversion allows selection of a video format conversion.
The choices offered depend on the AJA device present in your system, the
installed firmware version, and the Primary and Secondary format selected.
All conversions use AJA 10-bit hardware on the card.
Down-conversion display mode choices that may be available include:
• Anamorphic: full-screen
• Letterbox: image is reduced with black top and bottom added to image area
with the aspect ratio preserved
• Crop: image is cropped horizontally to fit new screen size
The table below contains the available Io Express down-conversion options.

Conversion Icon
When an input or output is a different standard than the framebuffer, the
Io Express may be down-converting the signal to the selected standard. This may
be automatic, because it’s detected an input signal that differs from the standard
currently selected, or because you’ve explicitly told it to convert. In either case,
the block diagram will show the conversion by displaying a conversion icon in
between the input/output and the framebuffer.
Figure 7. Down -Convert Icon
Controlling Application
It is important to understand that the computer can contain many applications
that can use the AJA device (as you switch from window to window) and it may
not always be obvious which currently controls it.
Figure 8. Control Panel In Use Message (in red)
In the top right corner, the Control Panel displays the name of the application
controlling the unit. In some cases, applications may not always properly “let go”
of the I/O interface as another takes over—you’ll be able to tell by looking at the
Control Panel.
Presets
Setups can be named and saved as a snapshot (Preset) for recall at any time. You
can save various AJA device Control Panel configurations associated with your
frequent tasks. You don’t have to spend time resetting interface configurations,
just load the previously saved Preset for each task. See "Saving, Loading and

Default Preferences
When an AJA device starts up, a preference can determine what settings it will
have it when it begins to operate. The AJA Control Panel offers two default
preference settings:
• Default User Preference - A preference stored from the last AJA device's
Control Panel settings to be used on next startup of AJA Control Panel. This
occurs on next restoration of the default state (triggered by start up of host
CPU, startup of the AJA device, or when a third-party application releases the
AJA device).
• Default Global Preference - A preference saved for use as a global default start
state for an AJA device that can be shared by multiple users, applied on first
startup, or by pressing the Control Panel Reset Device... button.
Default User Preference
The Default User Preference file (com.aja.devicesettings) exists to immediately
and automatically store all parameter changes made by a user on a particular AJA
device. When any control is changed in the Control Panel, that change is recorded
in the Default User Preference file stored in a unique location on that computer
that is dedicated to that particular device and serial number. Then, when AJA
Control Panel is restarted for any reason, the AJA device being controlled restores
the settings it had when Control Panel was last closed.
The Default User Preference file can be accessed at the following locations.
On Mac:
• From the Finder, hold down the Option key (to display the Library directory)
and click on Go/Library/Preferences/com.aja.devicesettings.
On Windows:
• C:\Users\<USER_NAME>\AppData\Local\aja\com.aja.devicesettings
NOTE: Clicking on the AJA Control Panel Erase All Prefs button deletes the existing
Default User Preferences file from this location. This file will be recreated as soon
as any Control Panel setting is changed.
Default Global Preference
An administrator can establish a house standard for an AJA device by copying
a preference file to a shared computer location. Once placed at that location, it
becomes a Default Global Preference file where it will establish a standard default
startup state for all users of that AJA device using that computer system. These
settings preempt the initial AJA factory default settings, and are applied when an
AJA device is first powered up, or when the Control Panel Reset Device button is
pressed.
Io Express Capture, Display, Convert v14.016www.aja.com

To establish a Default Global Preference, the administrator first configures the
AJA device (which automatically creates a "com.aja.devicesettings" Default User
Preference file in the location identified above) and then copy or move or that
file to the correct computer locations (manually or by pushing it out across the
network) on all the computers that use the AJA device.
NOTE: If the user makes changes to an AJA Device's Control Panel settings, those
changes are saved to the Single-User Preference file, which will take priority over
the Default Shared Preference file.
The shared computer locations for a Default Global Preference file are:
On Mac:
• From the Finder, click on Go/Computer/<System HD>/Users/Shared/AJA/
and copy or move the "com.aja.devicesettings file" described above to this
location.
NOTE: The "AJA" folder needs to be created manually at this location before moving the
preference file into it.
On Windows there are two possible shared locations depending on your system:
• C:\Users\Public\Aja\
• C:\Users\All Users\Aja\
Copy or move the "com.aja.devicesettings file" described above to one of
these locations.
NOTE: The AJA Control Panel Info screen displays the path to the Default Global
Preference file on that computer, if it exists.
NOTE: Clicking on the AJA Control Panel Erase All Prefs button does NOT delete an
existing Default Global Preference file from this location.

AJA Control Panel Function Screens
Control Screen
The Control Screen is where you set the Default Output, what the device outputs
when no application has control of the board. This screen also has controls for
setting the genlock source, and for setting the Horiz and Vert timing offsets. The
top of the Control Screen shows the current state of the device and also shows
the name of the Application which has control of the board, if there is one.
Default Output
Many video applications can grab control of the Io Express, so its outputs can
change dynamically. The Default Output settings are used to select what will be
output when no third-party video application is controlling Io Express.
Video Output
• Input Passthrough - This selection directs Io Express to route video from its
selected input through the card for processing and output.
• Test Pattern - This selection directs Io Express to output a preset pattern
when no other application is in control. The pattern is selected from the Test
Pattern dropdown list below, or a graphic file can be chosen.
• Hold Last App - This selection directs Io Express to hold and output the last
frame of video from the last application to control Io Express. This can be
helpful when operating in an environment where you’re switching back and
forth between multiple application windows.
Test Pattern
With Test Pattern selected above, you can choose the pattern type. Select from:
• Black, Color bars (75% or 100%), Ramp, Multiburst, Line Sweep, Multi Pattern,
or Flat Field, Check Field, White, Border, Linear Ramp, Slant Ramp, Zone Plate,
Color Quadrant, or Color Quad Border.
Io Express Capture, Display, Convert v14.018www.aja.com

Playback Timing
Use these controls to set the Genlock source and Timing adjustment.
Genlock
Selects how Io Express will synchronize program video:
• Freerun: Generates sync without an external reference source
• Ref In: Use the Ref Video source for sync (usually an analog black burst video
signal)
• Video In: Use whichever video input source has been selected in the Inputs
screen for sync
For video stability and proper system operation, you can genlock all equipment
to house sync. However genlock is not required for Io Express due to its excellent
freerun accuracy. On the Io Express house sync is connected to “LTC/Ref In”.
Alternatively, Io Express can receive externally supplied Linear Time Code on that
same input connector. The LTC/Ref setting on the Input Select screen (see "LTC/
Ref" on page 21) selects how that input signal will be used.
Timing (Horiz and Vert)
NOTE: The Playback Timing controls are greyed out when in Capture Mode.
These two pull-downs allow output timing adjustment with reference to the Ref
Video source selected.
• Horizontal: The Horizontal reference can be adjusted by selecting a number of
pixels (clocks) to offset
• Vertical: The vertical reference can be adjusted by specifying a number of lines
to offset.
Format Screen
The Format Screen shows the video format currently in use by the Io Express
framebuffer (called the Primary Format) and allows you to change it. All
throughout the Control Panel, choices are always presented based on what
Io Express can do with the signals available and the inputs/outputs selected.
Io Express Capture, Display, Convert v14.019www.aja.com

Primary (Frame Buffer) Format

when it has not been specified by the application. This setting also determines
the VOut formats to be displayed (see "VOut Filters" on page 26). Choose
between:
• Prefer p Fmt - progressive frames non-interlaced output
• Prefer psf Fmt - progressive segmented frames
NOTE: If you change this option while your NLE is open and running, you may need to
then make a change in one of your NLE settings in order for this to be reflected
dynamically in the project.
Io Express Capture, Display, Convert v14.025www.aja.com

Analog Black
Select the settings for black level setup for the analog video. Choose from:
• 7.5 IRE
• 0 IRE
QuickTime Settings
VANC Checkbox
When checked, the VANC checkbox tells the Io Express to capture and process
any ancillary data in the SDI stream. This can include different types of metadata.
Applications such as Premiere Pro and Final Cut Pro will not capture or output this
data through the Io Express if this box is not checked.
NOTE: Io Express does not require enabling the VANC checkbox for Closed Captioning.
VOut Filters
These controls enable/disable output capabilities in the QuickTime VOut filter.
This filter is used by older applications that are built on legacy QuickTime
architecture such as FCP7, AJA TV and older versions of After Effects. Boxes that
are checked will define what framerate and resolution types will appear in the list
of available formats in the AJA hardware. For example, if 25/50 is unchecked, then
all resolution/framerate combinations with 25 or 50 fps will not appear in the list
of capabilities for the installed AJA hardware, when using QuickTime VOut filter
reliant application software.
Check the following to display that format, or leave unchecked to hide that
format.
• 23.98/29.97/59.94
• 24/30/60
• 25/50
Audio Setup Screen
Io Express Capture, Display, Convert v14.026www.aja.com

The Audio Setup screen shows the current settings for the analog audio output,
allowing you to re-configure it when desired.
Audio Monitor
This control selects which pair of channels from the NLE will be monitored. For
most editing scenarios this should remain as Ch 1-2, since most NLEs default to
dual track / stereo monitoring as a sum of the entire timeline.
NOTE: This setting only applies to dual channel monitoring environments (for example,
the headphone jack on the front of the Io Express).
Select from:
• Ch 1-2 through Ch 7-8
Analog Audio Monitor Level
This selection determines the analog audio output level (“FSD” is full-scaledeflection reading as measured on a VU meter). In addition to the front panel
monitor (headphone) output, this setting also effects the analog output via the
DB25 cable. Select from
• +24dBu, +18dBu, +15dBu, or +12dBu
Timecode Screen
The Timecode screen is used to select the timecode stream read for applications
that use it (for example, in AJA Control Room when the Timecode Source
preference is set to “Control Panel Setting” that application will read the selected
stream). This screen is also used for monitoring the RP-188 timecode embedded
in the digital data stream, for selecting a timecode offset (if required), and setting
timecode outputs.
Io Express Capture, Display, Convert v14.027www.aja.com

Input Settings
RP-188 Timecode <n>
In RP-188 timecode (SMPTE 12M-gg2) there can be multiple timecode types in the
data stream. Use this pull-down to select the one you wish to monitor:
• RP188 LTC (Linear timecode)
• RP188 VITC (Vertical Interval timecode)
• LTC Port input
The selection will be displayed in the timecode value displayed to the right of the
pull-down.
User Bits
For monitoring a variable framerate (VFR) timecode (such as Varicam), you may
wish to check the User-bits box. If you set this checkbox, Io Express will detect
and interpret the user-bits and display them next to the checkbox. You will see
the original framerate (30 fps in the figure below) followed by the adjusted frame
padding (two digits reporting discarded and retained frame padding).
NOTE: SMPTE 12M-2 is the updated name and specification for what was RP-188.
Output Settings
Use QuickTime Timecode (Mac OS Only)
This feature is for Final Cut Pro 7 (or earlier), VTR Exchange, and AJA TV only. When
checked, it directs Io Express to output timecode from the QuickTime timecode
track.
Timecode Burn-in
This pulldown selects whether the timecode value is displayed in a “burned-in”
window in video output. If set to “OFF”, timecode will not be keyed over the
video. If set to “Timecode”, then the timecode value will be keyed over the output
video for all of the Io Express outputs. This can be useful for synchronizing,
choosing edit points, dailies, and many other purposes.
Timecode Offset
When QuickTime timecode in disabled, this text entry field allows you to
generate a timecode based on the offset entry. You can select a framerate from
the pulldown menu at the right side of the pane. Use that same value here as the
source video to ensure the timecode is synchronized.
NOTE: SMPTE RP 188 defines a standard for the transmission of time code and control
code in the ancillary data space of a digital television data stream. Time code
information is transmitted in the ancillary data space as defined in ANSI/SMPTE
291M. Multiple codes can be transmitted within a single digital video data stream.
Other time information, such as real time clock, DTTR tape timer information,
and other user-defined information, may also be carried in the ancillary time
code packet instead of time code. The actual information transmitted through
the interface is identified by the coding of a distributed binary bit. Equipment
manufacturers can use the meta data for different purposes.
