The CH-2507 transmitter and receiver set can send uncompressed audio/video and IP data over a single run of CAT5e/6 cable at a distance up to 100 meters with the added benefit of control through the built-in RS-232 and IR ports and an LAN serving connection. The transmitter (PD) can be powered by the PoE (48V) function of the receiver (PSE), allowing for greater flexibility in installations.
