The ALPV154T is able to take the same HD input and send it to 4 different screens connected via the ALPV150R receivers. There is a feed through port on the unit to allow a local display or you can cascade another ALAV154T so you can supply 8 screens.
To help reduce cable clutter, the ADDERLink LPV150 has been designed to be powered by a USB port on your computer. Furthermore, this power is also transmitted alongside the video over the CATx cable, in turn powering your receiver unit.
