Highlights
- U-201C is a passive twisted pair transmitter, using five or more than five non-shielded cable to transmit video images.
- Using twisted pair transmitter effectively save labor costs, cable cheap, soft, easy to install, and effective project cost savings.
- The product is without power, plug and play, the effective transmission distance of 220 meters color, 350 meters black and white images.
- One five lines and can transmit four video, using differential signaling, suppress interference suppression and noise filtering.
Specification
The set is designed to transmit video signal from a single source using a twisted-pair cable.
One of the devices matches the 75 ohm impedance of the unbalanced source to the impedance of the balanced line usually formed by a pair of UTP cable, the second performs the opposite function.
The video signal can be transmitted over a distance up to 400 m (UTP CAT5e).
The installer should pay attention to connecting the appropriate wires to the correct terminals: (+) to (+) and (-) to (-).
Improper connection will cause interference.
Definition of 'Balun':
"Balun" is the short for "Balance-Unbalance", in CCTV applications meaning a transformer for changing the transmission medium from a coaxial cable to a twisted pair, and vice versa.

Definition of 'Balun':
"Balun" is the short for "Balance-Unbalance", in CCTV applications meaning a transformer for changing the transmission medium from a coaxial cable to a twisted pair, and vice versa.
The biggest advantages of using balanced transmission cables are lower costs, higher resistance to external interferences, and possibility ofusing longer transmission lines.
Due to identical arrangement of the two wires of a balanced line, the interferences are also the same and can be cancelled in a differential balanced input of the receiver.
