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.

1-2

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.

Recommended transmission ranges at 60 Hz

Video format Maximum range

Composite video and audio 800 feet
Component video and S-video 800 feet
640 x 480 500 feet
800 x 600 400 feet
1024 x 768 350 feet
1280 x 1024 300 feet
1600 x 1280 250 feet

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.

IN1124/28/30 Transmission System • Introduction

About the TP Receiver

The Extron IN1130 TP receiver receives the transmission of one
of transmitter’s proprietary video and audio signal over a TP
cable. The receiver then decodes the received signal and buffers
and distributes two identical video outputs on female 15-pin
HD connectors. The receiver buffers and distributes two
identical mono audio outputs on 3.5 mm mini jacks.

The receiver has a sharpness control that fine tunes the
compensation to optimize the video outputs for various cable
lengths.

Cable testing

To ensure proper cable termination, each transmission cable
system that uses CAT 5 cable should be tested (Extron’s skew­free UTP cable does not need to be tested). Testing the cable
from the RJ-45 connections at the transmitter and receiver gives
the most accurate indications of cable problems.

There are two varieties of cable runs: simple runs, in which a
single cable is terminated only at the transmitter and receiver,
and complex runs, which can include patch bays and multiple
terminations and lengths of cable. In either case, the entire
cabling system should be tested.

A complete test measures cable length and tests the wire map,
attenuation, NEXT, PSNEXT, ELFEXT, PSELFEXT, return loss,
ACR and PSACR. All of these tests are critical for digital data
transfer, but not for analog video. While all of these tests are
important indicators of the quality of the cable termination, the
most critical testing parameters for video transfer are wire map
(T-568-A or T-568-B termination) and pair length measurements.
The largest concern is equalization of skew between cable pairs.
Cable systems of 300 feet or less should exhibit no transmission
problems if they pass at least CAT 5 channel certification testing.

The Microtest OMNI SCANNER 2 performs comprehensive
certification testing to the proposed CAT 6 standards. Other
manufacturers also make testing equipment. The tests include
advanced diagnostics for troubleshooting the cause and location
of many cable and termination problems. For simple
installation testing, the Microtest MICRO SCANNER PRO tests
wire map and cable length, including individual cable pair
length.

Equalizing pair skew

The manufacturing process for network (CAT 5) UTP cable
leads to a condition called pair skew. For best results, pair skew
needs to be equalized when using the CAT 5 cable in A/V
applications. The design of Extron’s skew-free A/V UTP cable
minimizes pair skew to the point that equalization is not
required.

Skew exists between pairs when the physical length of one wire
pair is different from another. As the transmission cable length
increases, the amount of skew increases. Skew affects the
displayed image when the differential length between wire
pairs exceeds 2 feet, causing the timing of the red, green, and
blue video signals to appear out of alignment (horizontal
registration errors). A white vertical line on a black field can
appear as individual red, green, and blue lines that are close
together; the signal transmitted on the shortest wire pair leads
the other colors and appears to the left on the display.

UTP cable test equipment measures and reports wire pair
length. The report on the various pair lengths can be used in
equalizing pair skew. The nominal velocity of propagation
(NVP — the speed at which the signal travels on the
transmission line, measured as a percentage of the speed of
light) of TP cable is very close to that of conventional coaxial
cable. The similarity in NVP means that:

• by using an Extron IN9045-L6 15HD male-to-5 BNC male,
6’cable, to adapt the output on a 15-pin HD connector to
BNC connectors,

• and then adding an additional length of coax equal to the
length of pair skew, placed on the receiver’s output,

you can equalize the effects of pair skew (figure 2-8).
If UTP cable test measurement cannot be done, pair skew can

still be equalized by viewing a test pattern with a critical eye.
Examine the test pattern for loss of horizontal registration and,
through a process of trial and error, equalize any pair skew with
coax extensions on the red, green, and/or blue outputs.

Extron skew compensation coax cables are available in lengths
of 2 through 20 feet, see Appendix A for part numbers.

the rear panel output 15-pin HD connectors.

Outputing component video, S-video, or composite
video on the 15-pin HD connectors requires an
Extron IN9045-L6 15HD male-to-5 BNC male,
6’cable.

Troubleshooting

1. Ensure that all devices are receiving power. The

transmitter’s and receiver’s front panel Power LEDs
indicate that they are receiving power.

2. Ensure that the transmitter is receiving a video input.

3. Ensure that the TP cable(s) are properly terminated in

accordance with TIA/EIA T 568A or TIA/EIA T 568B
standards and that the RJ-45 connections are securely
made.

4. The transmission distance may be too short. Ensure that

the UTP cable is at least 50 feet long.

5. The transmission distance may be too long. Try

shortening the distance between the transmitter and
receivers.

6. Call the Extron S
