Twisted Pair (TP) Cable Advantages

Twisted pair cable is much smaller, lighter, more flexible, and less expensive than coaxial cable. These TP products make cable runs simpler and less cumbersome. Termination of the cable with RJ-45 connectors is simple, quick, and economical.

Transmission distance

The maximum distance is determined by the frequency and resolution of the signal that is input to the transmitter. The table below specifies the recommended maximum transmission distances and transmitter Pre-Peak switch positions (see item E on page 2-6) using Extron Enhanced Skew-Free A/V UTP cable or UTP CAT 5, 5e, or 6 cable, terminated with RJ-45 connectors.

NIt is possible to exceed the recommended distance; however, image quality may be reduced.

NThe MTP units are designed for and perform best with Extron Enhanced Skew-Free A/V cable terminated in accordance with the TIA/EIA T 568 A wiring standard. CAT 5, 5e, and 6 cables are acceptable, but less preferable. We also recommend the use of preterminated and tested cables. Cables terminated on site should

be tested before use to ensure that they comply with Category 5 specifications.

NThe recommendations shown in the table on page 4 apply for a single transmitter and receiver and for a transmission daisy chain. For example, the maximum suggested range for 1024 x 768 video is 300’ (90 m) with Pre-Peak off and 500’ (150 m) with Pre-Peak on whether the system consists of one transmitter and one receiver or a transmitter and three daisy-chained receivers.

NFor a daisy-chained system, the first receiver in the chain must be at least 100’ (30 m) from the transmitter when the Pre-Peak switch is on.

NFor a daisy-chained system, any receiver in the chain closer than 350’ (105 m) may experience some form of over-peaking when the Pre-Peak switch is on. An overpeaked image may appear bloomed.
