How does VLC work?

The VLC function works by, at a press of a button, projecting a stream of non-human readable characters in rapid succession on the local display that can be interpreted from a mobile device camera and translated into a human readable format.

This allows significantly more information from the PDU to be displayed in a more legible manner than the simple LED display can achieve. The mobile device (phone or tablet) can save this information and export to CSV.

This level of information would normally only be available over a unit's web interface or via software provided the device settings and IP address were configured. No prior configuration is required to access this data over VLC. The benefit of being able to populate a rack's power consumption and sensor data at a quick scan is enjoyed by all who have physical access to the rack and want a quick summary of the unit.
