TWIST-R-AUTO-M Active Video Receiver for Category 5 Unshielded Twisted-Pair cable (UTP)


TWIST-R-AUTO-M - Active Video Receiver converts a differential video signal into a standard one and is installed on the receiving end of the video line.

Receiver TWIST-R-AUTO-M has a line length automatic correction system, which compensates high-frequency signal losses in the line and automatically controls the video signal level. The receiver has an indicator of video signal presence and automated operation. The inputs of the receiver have galvanic isolation from the signal line as well as lighting protection. The receiver has galvanic protection from lighting and current surges with amplitude of up to 5 kA and a pulse width of up to 8/20µs, and also protection from constant differential voltage of up to 24 V or common voltages between the earth wire and cable wires of up to ±12 V.


When the TWIST-TA-M transmitter on the transmitting end of the video line and TWIST-R-AUTO-M receiver on the receiving end of the video line are connected in series, a high-quality colour video signal is transmitted through the unshielded twisted pair (UTP) cable at a distance of up to 900 metres (2952 feet).


Up to six TWIST-R-AUTO-Ms can be mounted to standard 19 inch 1U Rack mount. This device is called TWIST-R AUTO-1URM6.
