About this Manual

This manual documents the installation, features, and operation of the Extron IN1124 and IN1128 TP twisted pair (TP) transmitters/distribution amplifiers (referred to in this manual as “transmitters” or “transmitter/DAs”) and the IN1130 TP receiver (referred to in this manual as a “receiver”).

About the Transmitter/Receiver System

The Extron IN1124 and IN1128 transmitters and IN1130 receivers provide a system for long-distance distribution of computer (RGBHV or RGBS) video and mono audio over Extron’s skew-free A/V UTP cable or over CAT 5 unshielded twisted pair (UTP), shielded twisted pair (STP), or foil shielded twisted pair (FTP) cable. With adapter cables, the system can also distribute component video or S-video and/or composite video.

TP cable advantages

Extron’s skew-free cable or CAT 5 cable is a fraction of the size of coaxial cable, as well as being much lighter, more flexible, and far less expensive. These TP products make cable runs simpler and less cumbersome. Termination of the cable with RJ-45 connectors is simple, quick, and economical.

System distribution

The transmitters split and buffer the transmitted signal four (IN1124) or eight (IN1128) times. The receivers each have two RGBHV and audio outputs. With this combination of a transmitter/DA with a local monitor and four or eight buffered receivers, the input signal can be widely distributed.

Transmission distance

The minimum reliable transmission distance between transmitters and receivers is 50 feet. The maximum distance is determined by the output frequency and resolution. The table on the following page specifies the recommended maximum transmission distances using Extron skew-free A/V UTP cable or UTP CAT 5 cable, terminated with CAT 5 rated connectors.

Extron recommends using the highest quality cable available and affordable, with less than 8 nanoseconds/ 100 meters of skew (see Termination of TP cable in chapter 2). We also recommend the use of pre- terminated and tested cables. Cables terminated on site should be tested before use to ensure that they comply with Category 5 specifications.

The transmitters and receiver are designed for CAT 5 cable. The system can be used with CAT 3 cable, but video performance will be compromised and maximum cable lengths and video resolutions must be decreased.

It is possible to exceed the recommended distances, however, image quality may be reduced.

About the TP Transmitter/DAs

The Extron IN1124 inputs RGB video and computer audio, converts the input to an output comprising the video and audio, and distributes and transmits four identical proprietary signals over TP cables to up to four IN1130 TP receivers. The IN1128 distributes and transmits eight proprietary signals on TP cables.

Both transmitter models provide a buffered local monitor video output.

Both transmitter models sum the left and right channels of the unbalanced stereo audio input and transmit mono audio on the left and right channels. The transmitters have a local audio output on a 3.5 mm female mini jack connector.
