About the MTP 4T 15HD RS The Extron MTP 4T 15HD RS consists of four MTP T 15HD RS transmitters in a single enclosure. This set of transmitters and the Extron MTP RL 15HD RS and MTP RL 15HD RS SEQ receivers provide a means to distribute VGA or other high resolution video and RS-232 serial communications across long distances. The MTPs transmit and receive over Extron’s Enhanced Skew- Free A/V UTP cable or over CAT 5, 5e, or 6 shielded twisted pair (STP), unshielded twisted pair (UTP), or foil shielded twisted pair (FTP) cable. The MTP 4T 15HD RS can support four transmitter/receiver systems. Each system requires a transmitter and at least one connected compatible MTP receiver. Additional receivers can be daisy chained. N In this manual the term "transmitter assembly" refers to the MTP 4T 15HD RS. Each of the MTP transmitters in the assembly inputs a set of high resolution or low resolution video signals (RGB, component video, S-video, or composite video) on a 15-pin HD connector. Each transmitter also passes RS-232 serial data or control signals on 3.5 mm 3-pin captive screw connectors. The transmitters convert the video and RS-232 signals to proprietary signals and each outputs its set of signals to the compatible MTP receivers on an RJ-45 connector. The transmitters also make each video input available for local use on 15-pin HD connectors. Each receiver inputs the transmitted proprietary signal on an RJ-45 connector, converts the signal back into its high resolution video and serial data components, and outputs it locally. The RS-232 portion of the TP link: • Can be bidirectional in each system that consists of just one receiver (not a daisy chain); that is, the receiver can receive commands from the transmitter and pass RS-232 responses back to the transmitter. N By default, the RS-232 portion of the TP link is unidirectional only, from the transmitter to the receiver. If there is only one receiver in the system, you can configure that receiver for bidirectional RS-232 communications. Refer to the MTP 15HD RS Series manual. • Supports software flow control (XON, XOFF). N Hardware flow control is not supported. • Supports full duplex and half duplex operation. • Supports any baud rate (up to 38,400), data bits, parity, stop bits, and data format without configuration. N Higher rates are possible, but performance will vary as a function of baud rate and TP cable length. Up to eight receivers can be connected in series to a single transmitter, provided that the total distance from the transmitter’s TP output to the last receiver in the chain does not exceed the recommended distance for the resolution being used. N Each individual transmitter provides pre-peaking, which boosts the signal before it is transmitted. The receiver does not provide any pre-peaking control. The total recommended distance (see page 1-4) for an entire daisy chain is the same as for a single transmitter and receiver. The transmitter’s Pre-Peak switch has the same affect on the recommended transmission distance for a daisy chain as for a single transmitter and receiver. The SEQ version of the receiver also corrects the skew delay (misconvergence) commonly encountered when using CAT 5, 5e, or 6 TP cables for RGB video and component video transmission. N An SEQ receiver should not be necessary when Extron Enhanced Skew-Free A/V UTP cable is used. All four transmitters in the MTP 4T 15HD RS are powered by a single internal 100 VAC to 240 VAC, 50/60 Hz, 20 watts power supply that provides worldwide power compatibility. Introduction, cont’d MTP 4T 15HD RS • Introduction 1-5 1-4 MTP 4T 15HD RS • Introduction 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. Recommended transmission distances at 60 Hz Composite, S-video, Component 640 x 480 <300' (90 m) >350' (105 m) 800' (245 m) 1000' (300 m) 700' (215 m) 750' (240 m) 800 x 600 <300' (90 m) >350' (105 m) 550' (165 m) 650' (200 m) 1024 x 768 <300' (90 m) >350' (105 m) 500' (150 m) 600' (185 m) 1280 x 1024 <250' (75 m) >300' (90 m) 350' (105 m) 450' (135 ...
