  • Page 6: About This Manual

    About the MTP Universal Receivers Extron MTP U R RSA SEQ, MTP U R RS SEQ, MTP U R RS, and MTP U R A receivers are for long distance distribution of RGB, component (bi/tri level), S-video, or composite video signals over twisted pair cables.
  • Page 7 The MTP U Rs are a part of the Extron VersaTools distribution amplifiers, switchers, transmitters, receivers, and associated video accessories. The MTP U R models receive signals (high resolution RGB video, bi-level or tri-level component video, S-video and composite video) on an RJ-45 connector over Extron’s Enhanced Skew-Free™...

  • Page 8: Tp Cable Advantages

    The maximum distance is determined by the frequency and resolution of the signal transmitted. The following table specifies the recommended maximum transmission distances and transmitter Pre-Peak switch positions using Extron Enhanced Skew-Free A/V UTP cable or UTP CAT 5/5e/6 cable, terminated with CAT 5 rated connectors.

  • Page 9: Receiver Jumpers

    Receiver Jumpers The MTP U R receivers have three jumpers on the main board. Jumper 1 (JMP1) controls RS-232 directional communication, and Jumpers 2 (JMP2) and 3 (JMP3) control vertical and horizontal sync respectively. By default, JMP1 is closed on all models and configured to send serial data both ways (bidirectional), transmitter-to-receiver and receiver-to-transmitter.

  • Page 10: Setting The Jumpers To Positive Vertical And/Or Horizontal Sync Polarity

    Introduction, cont’d If applicable, reinstall the receiver and reconnect all cables. Setting the jumpers to positive vertical and/or horizontal sync polarity Jumper 2 is the controlling jumper for vertical sync, and Jumper 3 for horizontal sync. Jumpers 2 and 3 are to the left of Jumper 1, when viewed from the rear of the receiver.

Smooth Figure 16 — Power connector wiring To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter. As an alternative, an Extron P/S 123 Universal 12 VDC Power Supply, part #60-814-01, can power multiple MTPs or other Extron 12 VDC devices using only one AC power connector.

  • Page 21: Tp Cable Termination

    TP cable termination Figure 17 details the recommended termination of TP cables with RJ-45 connectors in accordance with the TIA/EIA T 568A or TIA/EIA T 568B wiring standards. Either standard can be used with CAT 5/5e/6 cable, but ensure that the same standard is used on both ends of the cable.

  • Page 25: Skew Delay Compensation

    Skew Delay Compensation CAT 5/5e/6 TP cable can lead to registration errors between the red, green, and blue video signals. Pair skew can be measured with test equipment or identified by viewing a crosshatch test pattern with a critical eye to determine if either the red, green, or blue video image leads (appears to the left of) the other two video images.

  • Page 26: Non-Seq Receivers Skew Compensation

    Non-SEQ receivers skew compensation Try using the following methods to minimize or eliminate pair skew: • Switch to Extron’s Enhanced Skew-Free A/V UTP cable. • Add a skew compensation cable equal to the length of pair skew to the receiver’s output.
