SYSTIMAX IBS LonWorks Systems Design Guidelines

1. Introduction Lucent Technologies’ SYSTIMAX Intelligent Building Systems (IBS) supports cabling for the installation of LonWorks technology based Systems using various SYSTIMAX IBS Category 5 components, for example, 1061/2061 Local Area Network (LAN) cable or 62.5/125-µm fiber optic cables. The purpose of this guide is to help customers identify and implement SYSTIMAX IBS connectivity solutions for systems based on LonWorks Technology. Lucent Technologies’ SYSTIMAX IBS is a modular, flexible building distribution system. It supports control systems and building automation devices and systems by providing cost-effective connectivity for intelligent building control and management. SYSTIMAX IBS is part of SYSTIMAX Structured Connectivity System (SCS), which supports data, voice, and imaging communications using economical and easy-to-handle 24-AWG unshielded twisted-pair (UTP) copper cables and/or 62.5/125-µm fiber optic cables to provide connectivity in an open architecture environment. SYSTIMAX SCS and SYSTIMAX IBS support cabling for Lucent Technologies equipment and for equipment by other vendors. LonWorks Technology offers manufacturers a solution to designing, building, installing, and maintaining control networks. This technology is based on a peer-to-peer architecture and needs no central controller because intelligent nodes (control devices) communicate directly with each other. Each node has the intelligence to perform control functions and can communicate with other nodes using the LonTalk protocol. These nodes can be linked together to implement applications in consumer electronics, factory automation, commercial building automation, home automation, vehicle controls, etc. See references and contact a Echelon Representative for further information.

SYSTIMAX  IBS LonWorks Systems Design Guidelines

LonWorks technology provides the components and tools required to design applications that distribute intelligence and control throughout a system. A central component in LonWorks product family is the Neuron Chip, which contains the LonTalk protocol stack and a dedicated applications processor. When nodes are required to communicate over long distances, transceivers are used. The LonWorks FTT-10A Transceiver is a free topology device that provides a physical communication interface between a Neuron Chip and a LonWorks twisted pair network. The FTT-10A is used to implement node-to-node communication, and may also be used as elements of repeaters and routers to extend networks. A number of cabling arrangements in support of LonWorks systems are possible and should be considered in relation to the various applications that customers plan to use. For these different applications and cabling configurations, there are signal loss budgets and other performance issues for signaling. The number of devices placed on a link or bus, and the cabling distances supported, are determined according to the electrical characteristics of the cable and of the different types of applications and configurations. Because of the many aspects that must be considered, an Application Guide is desirable to help our customers identify and implement various connectivity solutions. This document contains information on SYSTIMAX IBS, SYSTIMAX IBS Configurations, Planning Guidelines, General Wiring Guidelines, and Instructions for the installation of LonWorks FTT-10A communication channels. Systems employing the FTT-10A transceiver will usually have interfaces to endpoint devices (that is, temperature sensors, dampers, etc.). This guide does not cover endpoint devices. Contact your Lucent Technologies and/or your LonWorks representative to determine the support for endpoint devices. See the Glossary section at the end of this document for explanations of abbreviations and acronyms.

1.1 SYSTIMAX IBS Architecture SYSTIMAX SCS has a full line of products, which includes transmission media, cross-connect and interconnect hardware, connectors and adapters, transmission electronics, electrical protection devices, and support hardware. It consists of six (6) subsystems: Work Location, Horizontal, Administration, Backbone (Riser), Equipment Room, and Campus. See Figure 1-1 for location of the subsystems. The star physical topology is followed by the telecommunication and data communications industries and by the Electronic Industries Association/Telecommunications Industry Association (EIA/TIA)-568 Industrial and Commercial Building Wiring Standard. Expansion is simple in a star topology because stations are added outward from a central node. And because each link and node is independent of the others, changes, rearrangements, and troubleshooting are easy. The subsystems of SYSTIMAX IBS are the same as those of SYSTIMAX SCS, except the term "coverage area" is used instead of "work area." Coverage area refers to the area served by a SYSTIMAX IBS information outlet (IO) or a device terminated on the cable. SYSTIMAX IBS includes extended coverage area wiring, which is wiring between coverage areas. The coverage area is typically defined by the structure of the building, access to the coverage areas, and the logical use of those coverage areas. The coverage area is usually larger

than the average work area. SYSTIMAX IBS devices and IOs are typically mounted in different physical places than voice/data IOs—for example, in the ceiling, on the walls, on door jams, and on other building structures. The topology of the SYSTIMAX IBS architecture is shown in Figure 1-1. In addition to the centrally administered star wiring circuits, this architecture includes chained circuits, and redundant-path fault tolerant circuits. Typically, the electronic equipment will be installed in the main equipment room (MER) or a telecommunications closet (TC). A central administered star circuit provides direct communication from the electronic equipment to the devices connected to an IO. The devices at the IO may be administered in the TC into bridged circuit connections, or chain circuit connections. The primary design concept is to centralize the electronic controllers in the MER when possible and run cabling to the endpoint devices or secondary controllers. If the controllers cannot be centralized because of distance limitations or functional criteria, then controllers are distributed in the TC(s) to meet the system requirements.

Figure 1-2. SYSTIMAX IBS Subsystem Although the recommended maximum distance from the TC to the device or voice/data equipment is 328 ft (100 m), components of the horizontal distance are different. In both SYSTIMAX IBS and SYSTIMAX SCS there is an allowance of 19.7 ft (6 m) of cable in the closet. Because the IBS coverage area is larger than a typical work area, the recommended horizontal distance is shorter than in SCS.
