PCI20U Series data SHEET ® PCI20U Series — Universal ARCNET Card The PCI standard requires that plug-in boards use a controller chip. New features include command +3.3 V power source provided by the PC’s chaining, sequential access to internal LAN, and motherboard, making the +5 V power source obsolete. duplicate node ID detection. Bus contention In response to this development, Contemporary problems are minimized since the module’s interrupt Controls introduced a universal-voltage PCI ARCNET level and I/O base address are assigned through Network Interface Module (NIM) which is compatible Plug-and-Play (PnP) operation. There is no with both +3.3 Volt and older, 5-Volt computers. requirement for wait-state arbitration. The PCI20U product is a drop-in replacement for the The PCI20U Series exploits the new features of the PCI20 +5 V PCI card which removes work needed by COM20022 such as 10 Mbps communications for the user to migrate to +3.3 V PCI or PCI-X slot EIA-485 transceivers — DC-coupled and AC-coupled motherboards. This demonstrates the company’s (transformer) variants. Conventional 2.5 Mbps commitment to ARCNET technology and to their dipulse signalling is also supported. customer’s requirements for legacy installations. The PCI20U module has two LEDs on the board for PCI-X is an enhancement to the original PCI Local monitoring network operation and PCI bus access to Bus Specification enabling devices to operate at the module. It is equipped with an 8-position, speeds up to 133 MHz. If a PCI20U is installed into general-purpose DIP switch which could be used to a bus capable of PCI-X operation, the clock remains reassign the ARCNET node address without at the 33 MHz frequency — restricting all other removing the module. Ultimately, the node address is devices on that bus to the conventional PCI protocol. configured via software so the DIP switch can be used for user-defined functions. This device incorporates the COM20022 ARCNET Features • Interfaces ARCNET with PCI and PCI-X bus computers • Automatic configuration of I/O and interrupt • High-speed I/O access to its ARCNET controller • Supports coaxial and twisted-pair cabling including EIA-485 • CE Mark • RoHS compliant • Enhanced software capabilities over earlier generation ARCNET controllers • Suitable with all Contemporary Controls MOD HUB and AI Series active hubs • Variable data rates up to 10 Mbps utilising the various EIA-485 transceiver options DS-PCI20U00-BA0 Data Sheet — PCI20U Series Transceiver Options Dipulse (Analogue) Signals EIA-485 (Digital) Signals Coaxial Bus Topology (PCI20U-CXB) DC-coupled EIA-485 (PCI20U-485 or PCI20U-485D) Cards with -CXB transceivers accept RG-62/u cable via EIA-485 backplane mode is invoked in the -485 card BNC Tee connectors. Each node is a high-impedance via user software and in the -485D card via the card’s in both powered and unpowered states. BNC-style own hardware. Either card uses a 3-terminal screw 93Ω terminators must be applied to both ends of a bus connector* for twisted-pair up to 274 metres in length segment. The maximum segment length is 305 metres and up to 17 nodes. Use proper cable and maintain and up to 8 devices can share the segment. wiring phase integrity among all nodes. Use 120Ω termination and proper bias at each end of the bus. Coaxial Star Topology (PCI20U-CXS) AC-coupled EIA-485 (PCI20U-4000 or PCI20U-485X) In a -CXS coaxial star system, devices connect in a EIA-485 backplane mode is invoked in the -4000 point-to-point fashion with RG-62/u coaxial cabling not card via user software for segments up to 80 meteres exceeding 610 metres. If more than two cards share in length and up to 8 nodes. Backplane mode is the cabling, a hub is needed — because a -CXS card invoked by the hardware in the -485X card which provides the 93Ω of termination internally. supports up to 13 devices and a segment length of 213 metres. The -4000 card uses dual RJ-45 jacks. Twisted-Pair Bus Topology (PCI20U-TB5) The -485X card uses a 3-terminal screw connector*. Using dual RJ-45 jacks, a -TB5 dipulse transceiver Apply 120Ω termination at each end of the bus. supports up to 8 devices and 122 metres of shielded or unshielded twisted-pair. RJ-45 style 93Ω * Dual RJ-45 sockets replace the 3-pin connector if terminators must be applied at each end of the bus. the /J model is specified (see Ordering Information).
