Io 4K Plus Capture, Display, Convert v14.0r2 11 www.aja.com
HDMI output also supports:
• HDR 10 Support - HDR Infoframe metadata, compatible with HDMI 2.0a/CTA-
861.3
• HLG Support - compatible with HDMI 2.0b/CTA-861-G
NOTE: HDCP is not supported on either input or output. 4K 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.
RS-422 Machine Control
A female DB-9 connector provides connection for VTRs, camcorders, disk media
servers, and other devices using RS-422 SMPTE (Sony) protocol.
Reference Video and LTC Input
Two BNC connectors provide reference Input and LTC output. The Reference
Video input can also be used for LTC input. The selection of Reference (sync) or
LTC is set using the AJA Control Panel (
"Input Select Screen" on page 24
).
Supplying a reference signal to the Reference input allows you to synchronize
Io 4K Plus outputs to your house analog reference video signal (or black burst).
When connecting a reference video source, the locking signal should be the
same as the input format. It is possible in some circumstances to use an alternate
format video signal as long as the basic frame rate is compatible.
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 are
configured as Ch 1-4 input and Ch 5-8 output.
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.
Installing Software
NOTE: If your computer has previously had another video capture or multimedia device
installed, ensure you uninstall any related software before installing Io 4K Plus.
This will prevent any hardware or software conflicts.
Before installing the software package, ensure that your capture/editing
application is installed as detailed in its user documentation. Before using
Io 4K Plus with Avid Media Composer or other NLE application, it is best practice
to have installed and run the software at least once on your workstation. Next,
install the AJA software package.
If at a later date you add any Io 4K Plus supported applications that require
drivers, you must run the AJA install program again to install them.
