3.1 About HDBaseT™ Technology
HDBaseT™ is an advanced all-in-one connectivity technology (supported by the
HDBaseT Alliance). It is particularly suitable in the consumer home environment as
a digital home networking alternative where it enables you to replace numerous
cables and connectors by a single LAN cable used to transmit, for example,
uncompressed full high-definition video, audio, IR, as well as various control
signals.
The products described in this user manual are HDBaseT certified.
3.2 About Power over Ethernet (PoE)
Power over Ethernet (HDBaseT) passes electrical power along with data on
Ethernet cabling. This allows a single twisted pair cable to provide both a data
connection and electrical power to compatible devices. PoE is convenient, flexible
and safe requiring the use of fewer power outlets, simpler configuration and low
power connections over standard category cables. A 48V DC power supply
connects to the PoE transmitter and can power the PoE receiver up to a distance of
100 meters (320 feet). Beyond this range, a 12V DC power supply must be
connected to the PoE receiver.
The TP-780T is a PoE injector. It cannot receive power from
another PoE injector but only from a 48V DC power supply.
