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.).
Component Video Output: Io XT 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 XT.
A Note About YPbPr: Component Video, or YPbPr, has been given several names over time. YUV, Y/R-Y/B-Y, and
YCbCr, are just some examples. Although these various formats have some differences in
levels, they are all basically the same. Io XT uses the modern YPbPr terminology exclusively. Io
XT 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 via the AJA Control
Panel.
Io 4K Connectors These connectors are offered only on the Io 4K model.
Thunderbolt 2: The Io 4K provides the second-generation Thunderbolt ports to support UHD and 4K
signals. Two ports are provided for “daisy-chained” network configurations.
Bi-directional SDI I/O: Four bidirectional BNC connectors can be configured via the AJA Control Panel for:
• HD/SD inputs (x2) and outputs (x2)
• Or you can input or output 4 channels of video representing individual quadrants of
the higher definition Ultra HD (3840x2160) and 4K (4096x2160) formats.
NOTE: The Io 4K can only be configured for either input or output of 4K at a time. It cannot support
4K input and output at the same time since both require four BNCs.
Dedicated SDI HD/SD Output: One BNC connector is provided for full-time, real-time output of HD/SD video. 4K video is
down-converted to 2K HD and UHD is down-converted to HD.
Installing Io XT/4K Software

System software updates may occasionally become available to AJA Io XT/4K owners on
our website (www.aja.com). We recommend checking occasionally for both software
updates and additional product information.
NOTE: If your computer has previously had another video capture or multimedia device installed,
ensure you uninstall any related software before installing Io XT/4K This will prevent any
hardware or software conflicts.
If you add Io XT/4K supported applications at a later date and have not previously
installed the appropriate drivers, you must run the install program again selecting the
appropriate application support software to be installed.
