Power Supply Options
The transmitter can be powered:
  Locally with the supplied 12V DC adaptor or Lightware’s rack mountable PSU, or
  Remotely by a PoE-compatible power injector, like Lightware’s TPS-PI-1P1.
  Powering  by  a  matrix  board  over  the  TPS  (CATx)  cable.  Output  board  needs  to  be 
powered by an external PSU.
 SW4-TPS-TX240 transmitter is PoE-compatible and can receive power over the TPS line. 
The TPS-TX/RX95 extenders are not PoE-compatible thus not able to send/receive power to/
from the SW4-TPS-TW240 transmitter.
