  • Triad Rackamp 350 & 600 DSP V2.0 Instructions for IP Setup
    Triad RackAmp 350 & 600 DSP v2.0 Instructions for IP Setup & Advanced Features This document describes IP (Internet Protocol) features unique to our RackAmp 350 & 600 DSP v2.0. Other connections, features and functions for these amps are very similar to our previous RackAmp 300/500/1000 DSP (v1.X). For more information see our RackAmp 350/600 DSP v2 Quick Start Guide and Triad SubAmp DSP v1.X Installer Setup Manual on the HOW TO or SUPPORT pages of our website http://www.triadspeakers.com/index.html . IP Features in RackAmp v2.0: IP for Setup – Use a computer or smart phone for remote setup when your subwoofer amps are located in different rooms than your subwoofers. IP for two Advanced Features 1. 6 Band Parametric EQ with 5 Hz resolution (-12dB to + 3dB; Q of .3 to 10). 2. Two Customizable Presets (default Volume & 1 band Parametric EQ). Note: IP allows Setup, Reset, or review by browser only; it is NOT for use with an external control system (Crestron, Control4, etc). IP Connections: • Via LAN: Connect RackAmp Ethernet Interface to a LAN with a standard Ethernet cable. If connecting to a wireless LAN, you can also use a Wi-Fi enabled smart phone, tablet, or laptop. The only issue when using a smart phone or tablet is that sliders do not work with the touch screen (the screen moves, not the slider). Instead, click on the number box above the slider and type the numbers in directly. • Direct to computer: Connect RackAmp’s Ethernet Interface direct to computer with an Ethernet crossover cable or a standard Ethernet cable with a crossover adaptor.

    SCAN90CP02 www.ti.com SNLS168L –MAY 2004–REVISED MARCH 2009 SCAN90CP02 1.5 Gbps 2x2 LVDS Crosspoint Switch with Pre-Emphasis and IEEE 1149.6 Check for Samples: SCAN90CP02 1FEATURES • Flow-through pinout 23• 1.5 Gbps per channel • LVDS/BLVDS/CML/LVPECL inputs, LVDS • Low power: 70 mA in dual repeater mode @1.5 Outputs Gbps • IEEE 1149.1 and 1149.6 compliant • Low output jitter • Single 3.3V supply • Configurable 0/25/50/100% pre-emphasis • Separate control of inputs and outputs allows drives lossy backplanes and cables for power savings • Non-blocking architecture allows 1:2 splitter, • Industrial -40 to +85°C temperature range 2:1 mux, crossover, and dual buffer • 28-lead LLP package, or 32-lead LQFP configurations package DESCRIPTION The SCAN90CP02 is a 1.5 Gbps 2 x 2 LVDS crosspoint switch. High speed data paths and flow-through pinout minimize internal device jitter, while configurable 0/25/50/100% pre-emphasis overcomes external ISI jitter effects of lossy backplanes and cables. The differential inputs interface to LVDS and Bus LVDS signals such as those on National's 10-, 16-, and 18- bit Bus LVDS SerDes, as well as CML and LVPECL. The SCAN90CP02 can also be used with ASICs and FPGAs. The non-blocking crosspoint architecture is pin-configurable as a 1:2 clock or data splitter, 2:1 redundancy mux, crossover function, or dual buffer for signal booster and stub hider applications. Integrated IEEE 1149.1 (JTAG) and 1149.6 circuitry supports testability of both single-ended LVTTL/CMOS and differential LVDS PCB interconnect.

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced.

  • QOS-Aware Middleware for Mobile Multimedia Communications
    Multimedia Tools and Applications 7, 67–82 (1998) c 1998 Kluwer Academic Publishers. Manufactured in The Netherlands. QOS-aware Middleware for Mobile Multimedia Communications ANDREW T. CAMPBELL [email protected] The COMET Group, Center for Telecommunications Research, Columbia University, Room 801 Schapiro Research Building, 530 W, 120th St., New York, NY 10027-6699 http://comet.columbia.edu/campbell, http://comet.columbia.edu/wireless Abstract. Next generation wireless communications system will be required to support the seamless delivery of voice, video and data with high quality. Delivering hard Quality of Service (QOS) assurances in the wireless domain is complex due to large-scale mobility requirements, limited radio resources and fluctuating network conditions. To address this challenge we are developing mobiware, a QOS-aware middleware platform that contains the complexity of supporting multimedia applications operating over wireless and mobile networks. Mobiware is a highly programmable software platform based on the latest distributed systems technology (viz. CORBA and Java). It is designed to operate between the application and radio-link layers of next generation wireless and mobile systems. Mobiware provides value-added QOS support by allowing mobile multimedia applications to operate transparently during handoff and periods of persistent QOS fluctuation. Keywords: middleware, mobile communications, adaptive algorithms, active transport, QOS 1. Introduction Recent years have witnessed a tremendous growth in the use of wireless communications in business, consumer and military applications. The number of wireless services and sub- scribers has expanded with systems for mobile analog and digital cellular telephony, radio paging, and cordless telephony becoming widespread. Next generation wireless networks such as wireless ATM (WATM ) will provide enhanced communication services such as high resolution digital video and full multimedia communications.
