Introduction This section introduces the MTP transmitters and receivers. Topics discussed in this section are: • About the MTP Transmitters and Receivers • TP Cable Advantages • Transmission Distance About the MTP Transmitters and Receivers The Extron MTP transmitters and receivers provide a system for long-distance distribution of NTSC, PAL, or SECAM video and audio.
TP Cable Advantages Twisted pair (TP) 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.
Installation This section describes the installation procedures, including: • Signal Jumpers for Generational Compatibility • Mounting Options • Panel Features and Connections CAUTION: Installation and service must be performed by authorized personnel only. Signal Jumpers for Generational Compatibility Over time, the MTPs have been redesigned, affecting the signal content of the TP cable wire pairs, changing the audio from stereo to mono, and eliminating the remote power capability.
Setting the Jumpers on Non AAP Models Figure 1. SHARP GAIN 1. Remove and retain the four screws (two on each side of the unit) that secure the cover to the MTP (see figure 1). Removing the MTP Cover 2. For the receiver, slide the cover slightly forward to clear the front panel adjustment knobs. 3. Lift the cover straight up. 4. If the transmitter or receiver is an audio unit, remove and retain the two screws that secure the audio board to the main (video) board (see figure 2).
5. Locate the jumper blocks (see figure 3) on the video board. Shift the jumper to the alternate location. Mono (default jumper position) Compatible with new model transmitter/receivers. Cannot remotely power transmitter/receiver Transmitter Front Panel Transmitter Rear Panel Receiver Front Panel Receiver Rear Panel Stereo Compatible with old model transmitter/receivers.

Setting the Jumpers on AAP Transmitters 1. Remove and retain the two screws that secure the back cover to the MTP (see figure 5). 1. Remove these screws. 2. Carefully pull the RJ-45 connector through this hole. OUTPUT − + POWER 12V 0.5A MAX Figure 5. Removing the MTP Cover 2. Pull the cover out of the way, carefully twisting the RJ-45 connector as necessary to slide it through the hole in the cover marked “Output.” 3.
Mounting Options UL Requirements The following Underwriters Laboratories (UL) requirements pertain to the installation of the MTP transmitter or receiver into a rack. 1. Elevated operating ambient — If the equipment is installed in a closed or multi‑unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (TMA) specified by the manufacturer. 2.

Mounting the MTPs on a Standard Rack Shelf Figure 8. Mounting the MTPs on a Rack Shelf Rack Mounting Instructions On the standard rack shelf, the MTP mounts in one of eight locations to the rear of the rack or in one of eight locations to the front of the rack. 1. Remove the feet from the bottom of the MTP, if installed. 2.
3. For furniture mounting — a. Hold the MTP with the attached brackets against the underside of the mounting surface. Mark the bracket screw hole locations on the mounting surface. b. Drill 3/32 inches (2 mm) diameter pilot holes, 1/4 inch (6.3 mm) deep in the mounting surface at the marked screw locations. c. Insert #8 wood screws into the four pilot holes. Tighten each screw into the mounting surface until just less than 1/4 inch of the screw head protrudes. d.

CAUTIONS: • The length of the exposed (stripped) portion of the copper wires is important. The ideal length is 3/16 inches (5 mm). Longer bare wires can short together. Shorter bare wires are not as secure in the direct insertion connectors and could be pulled out. • The captive screw audio connector can easily be inadvertently plugged partially into one receptacle and partially into an adjacent receptacle. This misconnection could damage the audio output circuits.

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. You can use either standard, but ensure that you use the same standard on both cable ends. WARNING: Damage may occur to the unit if TP cables are miswired as crossover cables.
