The CH-1507 transmitter and receiver set can send uncompressed audio/video and IP data over a single run of CAT5e/6/7 cable at a distance up to 100 metres. It has the added benefit of control through the built-in RS-232 and IR ports and a bi-directional LAN serving connection. The Receiver (PD) can be powered by the PoE (48V) function of the transmitter (PSE), allowing for greater flexibility in installations.
