Composite Video & Stereo Audio over Twisted Pair Transmitter

711N

Overview

The 711N is a twisted pair transmitter for composite video and unbalanced stereo audio signals. The 711N transmitter converts composite video and stereo audio to a twisted pair signal and the 712N receiver converts the twisted pair signal back into composite video and stereo audio signals.

•  Bandwidth — 85MHz — 3dB.

•  Twisted Pair Input/Outputs — RJ–45 connectors.

•  Looping Input — 712N (RJ–45).

•  Selectable Input Signal Termination — 712N.

•  Level (Gain) and EQ (Peaking) Controls — 712N.

•  Power Connect™ System — A single connection to the transmitter or the receiver powers both units when the devices are within 150ft (50m) of each other.

•  System Range — Up to 400m (1200ft).

•  Cable — UTP (unshielded twisted pair) or STP (shielded twisted pair) such as CAT 5.

Features

• Range >6.2 miles (10km)

Applications

•  Remote monitoring for CCTV, medical, school and broadcast applications.

•  Existing facilities with TP cable already installed.

•  Teleconferencing in offices and hospitals using existing intercom or telephone wiring.
