Installation Overview
1. If not previously installed on your Thunderbolt equipped computer, ensure
that appropriate third party application software is installed as detailed in
its user documentation.
2. Download and install the latest Io 4K Plus software from:
https://www.aja.com/en/support/downloads
3. Connect your Io 4K Plus to your computer using an appropriate Thunderbolt
cable.
4. Connect the video and audio inputs and outputs.
5. Power up the unit (AC supply or battery). The Io 4K Plus will startup
automatically.
6. AJA recommends that you now run AJA Control Panel, as this allows you to
verify that the installation has completed successfully.
NOTE: AJA Control Panel will prompt you to update firmware (if the new software
package contained a firmware update for your AJA device).
System Test Application
AJA System Test is a utility for measuring system performance. The application
includes:
• System Disk Test
• AJA Device Test
• Disk + Device Test
• System Report
The application tests Read and Write, Capture and Playback speeds tests 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.
Theoretically the best test is to fill your storage disk to 80% and then test capture
at the highest data rate you will use.
