L’étiquette du Département de Communications Canadien identifie un équipement certifié. Cette certification veut dire que l’équipement satisfait à certaines exigences de sûreté, d’exploitation, et de protection de réseau de télécommunications. Le Département ne garantit pas que l’équipement fonctionnera à la satisfaction de l’utilisateur.

Avant d’installer cet équipement, les utilisateurs doivent s’assurer qu’il est admissible d’être connecté aux installations de la société de télécommunications locale. L’équipement doit également être installé en utilisant une méthode de connexion admissible. Dans certains cas, le câblage intérieur d’une société associé avec une ligne unique de service individuel peut être étendu par un ensemble connecteur certifié (prolongateur téléphonique). Le client doit être conscient du fait que la conformité aux conditions ci-dessus n’empêcherait pas la dégradation de service dans certaines situations.

Les réparations à l’équipement certifié devraient être effectuées par un établissement d’entretien canadien autorisé qui est désigné par le fournisseur. Toutes réparations ou modifications faites par l’utilisateur à cet équipement ou aux mauvais fonctionnements de l’équipement, peut donner à la société de télécommunications un sujet de demander que l’utilisateur déconnecte l’équipement.

Les utilisateurs devraient s’assurer, pour leur propre protection, que les connexions électriques mises à la masse du service électrique, des lignes téléphoniques et du système de tuyaux d’eau métallique, si présent, sont interconnectées. Cette précaution pourrait être très significative à la campagne.

Avertissement:

Les utilisateurs devraient ne pas tenter de faire de telles connexions eux-même, mais devraient prendre contact avec l’autorité d’inspections électriques ou un(e) électricien(ne) convenable.

Note—Le numéro de chargement (load number / LN) assigné à chaque dispositif terminal indique

le pourcentage du chargement total à être connecté à une boucle téléphonique qui est utilisé par le dispositif, pour empêcher une surcharge. Le raccordement sur une boucle peut consister de quelque combinaison de dispositifs, assujettis uniquement à l’exigence que le total des numéros de chargement ne peut pas dépasser 100.

NetController

This manual describes the installation, care and use of the Continuum NetController CPU module.

The Continuum NetController CPU module is part of the Andover Controls Continuum Ethernet-based intelligent building system. The Continuum system allows you to costeffectively mix and match DIN rail-mounted CPU, power supply, and various combinations of I/O modules and user interfaces to meet your control and monitoring needs. This CPU includes an impressive array of features.

The Continuum NetController with flash EPROM is the high-powered Central Processing Unit (CPU) module and network manager for the Andover Controls Continuum intelligent building system.

High-Speed Communications

The NetController acts as the system coordinator for the Continuum I/O modules, providing integrated global control and monitoring, history logging, local and remote alarming. It communicates with the I/O modules via LON communications and a choice of RS-485 or free topology bus media. In addition, an optional Ethernet support interface allows the NetController to communicate with other NetControllers and Continuum Workstations over a high-speed 10Mb Ethernet Local Area Network (LAN) using the TCP/IP protocol. Two different Ethernet interface modules are available¾you can choose either a 10BASE-2 (thin coax) or 10BASE-T (twisted pair) cable media.

Flash Memory

NetController’s 2Mb of flash EPROM (expandable to 4Mb) allows you to download software revisions over Ethernet or standard telephone lines using a Continuum workstation. This flash memory feature eliminates the need to perform EPROM changeouts in the field.

Continuum CPU Reference 1

Serial Communications

NetController’s four programmable communications ports can be configured as either an RS-232 or an RS-485 interface to modems, printers, third-party devices, and the Infinity Infinet field bus network. Andover Controls has developed an extensive library of thirdparty software interfaces, including tie-ins to chiller control panels, fire alarm systems, emergency generator systems, bar code readers, elevator controls, and video switchers.

Plain English® Programming

The Continuum NetController can be configured to meet the exact requirements of your application using the powerful Andover Controls Plain English programming language. Programs are entered into NetController using the Continuum Workstation. The program is then stored in, and executed by, the NetController.

Software Capabilities

The dynamic memory of the Continuum NetController can be allocated for any combination of programs, scheduling, alarming, reporting and data logging. Our objectoriented Plain English language with intuitive keywords provides easy operation and programming. In addition, Plain English ‘s pre-defined and customized functions and powerful math capabilities reduce programming time for repetitive applications.

Optional Auto-Baud Modem

The optional Andover Controls Continuum modem allows NetController to communicate and exchange data over standard voice grade telephone lines with speeds up to 14.4K baud. The modem has built-in data compression and error-correction protocols, auto- dial/auto-answer capabilities, and is UPS-supported.

UPS Operation

The Continuum NetController incorporates software programmable battery backup that reduces or eliminates the impact of power failure. On UPS, the NetController CPU can turn off I/O power to extend battery life and support modem and network operation for up to four hours. In addition, NetController can go into a low-power mode in which only the DRAM and real-time clock are powered for up to 72 hours.

Modular Design for Snap-Together Connection

NetController features a sleek, lightweight casing designed for natural convection cooling. Built-in connectors on either side of the NetController module allow power transmission from the power supply module and communication signals to the Continuum I/O modules to feed through easy snap-together connections. Built-in quick-release fasteners at the back of the module are provided for DIN rail mounting¾no tools required. These fasteners also snap into a locked position for panel mounting. The NetController module is designed for mounting in an optional NEMA 1-sytle Continuum enclosure.
