  • PCI20EX PCI Express (Pcie)
    PCI20EX PCI Express (PCIe) Bus ARCNET® Network Interface Modules INSTALLATION GUIDE INTRODUCTION The PCI20EX series of ARCNET network interface modules (NIMs) links PCI Express (PCIe) bus compatible computers with the ARCNET local area network (LAN). Since most PC motherboards have migrated from the legacy PCI and PCI-X Bus, a PCI Express style NIM is required. The PCI20EX series is compliant to the PCI Express Card Electromechanical Specification Revision 2.0 and both standard height and low-profile brackets are provided. The PCI Express interface allows for jumperless configuration and Plug and Play operation. The module operates with either an NDIS driver or a null stack driver in a Windows® environment. The PCI20EX incorporates the COM20022 ARCNET controller chip with enhanced features over the earlier generation ARCNET chips. New features include command chaining, sequential access to internal RAM, duplicate node ID detection and variable data rates up to 10 Mbps. Bus contention problems are minimized since the module’s interrupt and I/O base address are assigned through Plug and Play. The PCI20EX exploits the new features of the COM20022 which includes 10 Mbps communications utilizing the various EIA-485 transceiver options. Each PCI20EX module has two LEDs on the board for monitoring network operation and bus access to the module. It is equipped with an 8 position, general purpose DIP switch typically used to assign the ARCNET node address. Ultimately, the node address is configured via software so the DIP switch can also indicate user-defined functions such as data rate, cable interface, or master/slave status of the system.

  • Local Area Network
    Local area network A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.[1] By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involvesleased telecommunication circuits. Ethernet and Wi-Fi are the two most common technologies in use for local area networks. Historical technologies includeARCNET , Token ring, and AppleTalk. A conceptual diagram of a local area network. Contents History Cabling Wireless media Technical aspects See also References External links History The increasing demand and use of computers in universities and research labs in the late 1960s generated the need to provide high- speed interconnections between computer systems. A 1970 report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation.[2][3] A number of experimental and early commercial LAN technologies were developed in the 1970s. Cambridge Ring was developed at Cambridge University starting in 1974.[4] Ethernet was developed at Xerox PARC between 1973 and 1974.[5][6] ARCNET was developed by Datapoint Corporation in 1976 and announced in 1977.[7] It had the first commercial installation in December 1977 at Chase Manhattan Bank in New York.[8] The development and proliferation of personal computers using the CP/M operating system in the late 1970s, and later DOS-based systems starting in 1981, meant that many sites grew to dozens or even hundreds of computers. The initial driving force for networking was generally to share storage and printers, which were both expensive at the time.

We can just concentrate on the software, which will allow us to bring new features to market sooner.” Motor drive with Smart Trac The list of features made possible with the Smart Trac drive fam- ily include: ■ programmable using the programming languages specified in IEC-1131-3 ■ isolated RS232 serial port for PC communication ■ RS232

  • ARCNET Tutorial
    ARCNET Tutorial 1 w w w. c c o n t r o l s. c o m ARCNET®—Embedded Network, Industrial LAN or Fieldbus? ARCNET was originally classified as a local area network or LAN. A LAN is defined as a group of nodes that communicate to one another over a geographically-limited area usually within one building or within a campus of buildings. That was the intent of ARCNET when it was originally introduced as an office automation LAN by Datapoint Corporation in the late 1970s. Datapoint envisioned a network with distributed computing power operating as one larger computer. This system was referred to as ARC (attached resource computer) and the network, that connected these resources, was called ARCNET. ARCNET’s use as an office automation network has diminished; however, ARCNET continues to find success in the industrial automation industry because its performance characteristics are well suited for control. ARCNET has proven itself to be very robust. ARCNET also is fast, provides deterministic performance and can span long distances making it a suitable fieldbus technology. The term fieldbus is used in the industrial automation industry to signify a network consisting of computers, controllers and devices mounted in the “field”. ARCNET is an ideal fieldbus. Unlike office automation networks, a fieldbus must deliver messages in a time predictable fashion. ARCNET’s token-passing protocol provides this timeliness. Fieldbus messages are generally short. ARCNET packet lengths are variable from 0 to 507 bytes with little overhead and, coupled with ARCNET’s high data rate, typically 2.5 Mbps, yields quick responsiveness to short messages.

  • Fiber Optic "Cable" Coaxial Cable Types Twisted Pair
    1 Local Area Network A local-area network is a computer network covering a small geographic area, like a home, office, or group of buildings e.g. a school. The defining characteristics of LANs, in contrast to wide-area networks (WANs), include their much higher data-transfer rates, smaller geographic range Metropolitan Area Network Metropolitan area networks, or MANs, are large computer networks usually spanning a city. Metropolitan area networks can span up to 50km, devices used are modem and wire/cable They typically use Optical fiber connections to link their sites. A MAN is optimized for a larger geographical area than a LAN. Wide Area Network Wide Area Network (WAN) is a computer network that covers a broad area (i.e., any network whose communications links cross metropolitan, regional, or national boundaries Channel A Channel can take many forms, including ones suitable for storage which can communicate a message over time as well as space. A connection between initiating and terminating nodes of a circuit. A single path provided by a transmission medium via either physical separation, such as by multi pair cable. Types of Channel Fiber optic "cable" Coaxial Cable Types Twisted Pair Fiber optic "cable" ● SPEED: Fiber optic networks operate at high speeds - up into the gigabits • BANDWIDTH: large carrying capacity • DISTANCE: Signals can be transmitted further without needing to be "refreshed" or strengthened. 2 • RESISTANCE: Greater resistance to electromagnetic noise such as radios, motors or other nearby cables. • MAINTENANCE: Fiber optic cables costs much less to maintain. Coaxial Cable Types Coaxial cable, or coax, is a cable consisting of an inner conductor, surrounded by a tubular insulating layer typically made from a flexible material, all of which is then surrounded by another conductive layer and then finally covered again with a thin insulating layer on the outside.
