This video demonstrates using AMP VLAN while On-Site to add a Just Add Power Transmitter or Receiver to a system that was previously configured. Add Device: On-Site requires that the switch already has a blank port prepared for the Transmitter/Receiver.
AMP - Advanced Matrix Programmer - is a software that configures 3G and MaxColor Just Add Power devices into an HDMI matrix switching system.
