Introduction About this Manual This manual details the installation and operation of the Extron MTP U R series of mini twisted pair universal receivers.
The MTP U Rs are a part of the Extron VersaTools® line of basic 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™ A/V UTP cable, or over Category (CAT) 5/5e/6 shielded twisted pair (STP), unshielded twisted pair (UTP), or foil shielded twisted pair (FTP) cable.
Introduction, cont’d 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 and termination with RJ-45 connectors is simple, quick, and economical. Transmission distance The maximum distance is determined by the frequency and resolution of the signal transmitted.
N The transmitter and receiver 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 cables are acceptable but less preferable. 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 5/5e/6 specifications. The recommendations shown in the table apply for a single transmitter and receiver.
Introduction, cont’d 6. If applicable, reinstall the receiver and reconnect all cables. N Jumper 1 should be set to uni-directional when an MTP DA is installed as part of the system to avoid any RS-232 /Audio detection issues. When an MTP U R series receiver is used with an MTPX Matrix Switcher, it should be set to unidirectional for transmitter to receiver communication, otherwise it should be set to bi-directional when using the RS-232 output insert connections on the switcher.

Installation Installation C Installation and service must be performed by authorized personnel only. The 1U high, quarter rack width, MTP U R receiver can be mounted on a rack shelf, to a rack without a shelf, under a desk or tabletop, or on a projector bracket. UL guidelines for rack mounted devices The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the MTP U R receiver in a rack. 1.
• RSU 129, Standard universal 1U rack shelf kit (part #60-190-01) • RSB 129, Basic universal 1U rack shelf (part #60-604-02) On the standard rack shelf, the MTP U R mounts in one of four locations to the rear of the rack or in one of four locations to the front of the rack. MT PT VG A RS VersaTools Basic Rack Shelf MT PT VG A RS Quarter Rack Width False Faceplate Use 2 mounting holes on opposite corners.
Installation, cont’d N Fxtron recommends where more than one shelf is required, rack mount shelves are installed at least 1U apart, to allow for air flow and proper cooling between the shelves. 3. Install false faceplate(s) or other unit(s) to the rack shelf. 4. Mount the shelf into the rack. Back of the rack mounting The MTP can be mounted to the rear of a rack using the Extron MBB 100, VersaTools® back of the rack mounting kit (part #70-367-01).

Installation, cont’d 12 1. Remove the feet from the bottom of the MTP, if they are installed. 2. Attach the mounting brackets to the MTP with the machine screws provided. 3. For furniture mounting, hold the MTP with the attached brackets against the mounting surface. Mark the bracket screw hole locations on the mounting surface. 4. For furniture mounting, drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.3 mm) deep in the mounting surface at the marked screw locations. 5.

See “Power supply wiring” to wire the connector. b Input 1 connector — Connect one end of the cable from the transmitter. See “TP cable termination” to wire the RJ-45 connectors. C c Do not connect these devices to a computer data or telecommunications network.

N Wire the supplied male power connector (plug) as in figure 16. Smooth Ridges A A Captive Screw Connector SECTION A–A Power Supply Output Cord Tie Wrap 3" 16 (5 mm) Max. Figure 16 — Power connector wiring C N Power supply voltage polarity is critical. Incorrect voltage polarity can damage the power supply and the product.
TP cable termination RJ-45 termination must comply with TIA/EIA T 568A or TIA/EIA T 568B wiring standards for all connections. N 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.
Installation, cont’d Front Panel Controls and Indicators Front panel features on the MTP U R receivers are shown below.
a b Power LED — Indicates power is applied to the MTP. c Select button (SEQ models only) — This recessed button selects the red, green, or blue video signal to adjust and resets all three video signals to a skew delay of zero nanoseconds. Use a Tweeker to press and release this button to cycle and select the red, green, or blue video signal to adjust. The selected signal is indicated by the Red, Green, and Blue LEDs (d).
Installation, cont’d The maximum setting (at the clockwise limit) provides 100% peaking. Adjust this control while viewing the displayed image to obtain the optimum picture sharpness. See “Peaking and Level Adjustment” section below for details. N To avoid possible video loss due to errors in the video format detection, the user should always start with minimal peaking and level, then only increase values as required. h Audio LED (MTP U R RSA SEQ models only) — This LED lights in audio mode by default.
N Since this product differs from the standard MTP receiver by its ability to auto detect the video format received, based on the video signal quality, it requires a reasonable adjusted signal for both level and peaking. There is some margin for over peaking, but if too much over peaking occurs the signal may not be recognized due to signal loss. Skew Delay Compensation CAT 5/5e/6 TP cable can lead to registration errors between the red, green, and blue video signals.
Installation, cont’d N A 2-nanosecond (ns) adjustment is very fine. Up to 10 ns of delay may be necessary before a change in the display is detectable. Maximum delay possible is 62 nanoseconds. c. Use a Tweeker or other small screwdriver to press the Select button one more time to save the most recent adjustment or allow the 10-second timeout to elapse. 4. If the remaining color is left shifted, repeat step 3.
