Anleitung Zusammenfassung
RS-232 function When the audio/RS-232 portion of the TP link is RS-232, it is either unidirectional or bidirectional, selectable by a DIP switch. 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 set it to be bidirectional. When bidirectional is selected, the receiver can receive commands from the transmitter and pass RS-232 responses back to the transmitter. See the BI-RS232 DIP switch description in "Rear panel features", on page 2-7, to allow bidirectional RS-232 communications. The RS-232 link: • 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 varies as a function of baud rate and TP cable length. 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 N VGA video transmitters provide pre-peaking, which boosts the signal before it is transmitted. The maximum distance is determined by the frequency and resolution of the signal that is input to the transmitter. The table on the next page specifies the recommended maximum transmission distances and transmitter Pre-Peak switch positions (refer to the applicable transmitter manual) using Extron Enhanced Skew-Free A/V UTP cable or UTP CAT 5, 5e, or 6 cable, terminated with RJ-45 connectors. N It is possible to exceed the recommended distance; however, image quality may be reduced. N Resolutions marked with an asterisk (*) in the table on the next page have the same range specifications at 75 Hz. Introduction, cont’d MTP R 15HD RSA D • Introduction 1-4 N The 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.

The installation must conform to national and local electrical codes and to the wall plate’s size requirements. UL/safety requirements The following Underwriters Laboratories (UL) requirements pertain to the installation of the Decora receiver into a wall or furniture. 1. This unit must not be connected to a centralized DC power source or used beyond its rated voltage range. 2. This unit must be installed in a UL listed junction box. 3. This unit must be installed with conduit in accordance with National Electrical Code. Preparing the site and installing the wall box Choose a location that allows cable runs without interference. Allow enough depth for both the wall box and the cables. The box should be at least 2.5" (6.4 cm) deep to accommodate the connectors and cables. Install the cables into the wall, furniture, or conduits before installing the wall plate. N The Decora unit is very deep and has a connector and a cable pigtail on the back side (figure 2-1 on page 2-3). Extron recommends its 1-gang or 2-gang junction boxes (part # 980130 or 980084), whi...
