1-5 TPX 88 Matrix Switchers • Introduction
Transmission distances
The minimum reliable transmission distance between transmitters and receivers is
50 feet for most models. The maximum distance is determined by the output
frequency, resolution, and the transmitter/receiver family. The table below lists the
recommended maximum transmission distances for most transmitter/receiver
families using Extron Enhanced Skew-Free A/V UTP cable, terminated with CAT 5
rated connectors.
Refer to each product’s user manual to determine the ranges for that family of
products.
Recommended transmission ranges at 60 Hz
Video format Maximum ranges
Composite video, S-video, and
component video and audio
800" (245 m) – 1000" (300 m)
640 x 480 500" (150 m) – 1000" (300 m)
800 x 600 400" (120 m) – 800" (245 m)
1024 x 768 300" (90 m) – 600" (185 m)
1280 x 1024 200" (60 m) – 450" (135 m)
1600 x 1280 150" (45 m) – 450" (135 m)
It is possible to exceed the recommended distances, however, image quality may
be reduced.
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.
Extron Skew-Free A/V UTP cable is recommended for most applications.
CAT 5 cable can be satisfactorily used for some products (refer to each
product’s user manual). The system can be used with cable other than that
recommended, but video performance will be compromised and maximum
cable lengths and video resolutions must be decreased.
