Product Overview

The CPCI22 Series links CompactPCI bus compatible computers with the ARCNET Local Area Network (LAN) for a complete solution for industrial and telecommunications applications. You'll find this product has a low-profile, 3U form factor with hot-swap capability and high-performance.

This device allows for both jumperless configuration and Plug-and-Play (PnP) operation. Hot-swapping is a significant benefit for operators of high-availability systems. Both NDIS and null-stack drivers are available for use with the module in a Windows environment.

It is equipped witht the ARCNET COM20022 controller chip and includes these features: command chaining, sequential access to internal RAM, duplicate node ID detection and variable data rates up to 10 Mbps. Bus contention problems are reduced since the module's interrupt level and I/O base address are assigned through PnP. There is no requirement for wait-state arbitration.

Each CPCI22 module has two LEDs for monitoring network operation and bus access to the module. It is designed with an 8-position, general-purpose DIP switch typically employed to assign the ARCNET node address. If the node address is configured via software, the DIP switch could instead indicate a user-defined function such as data rate, cable interface, or master/slave status of the CompactPCI system.

Six models of the CPCI22 are available. The CPCI22-4000 provides tranformer-coupled AC EIA-485 operation. The CPCI22-485 supports DC-coupled EIA-485 backplane mode. The CPCI22-CXB supports a coaxial bus configuration—often requiring no hubs. The CPCI22-CXS supports coaxial star configurations requiring external active or passive hubs if other than peer-to-peer topology is used. Other versions include the CPCI22-FOG-ST which supports fiber optic cable with ST connectors and the CPCI22-TB5 which supports twisted-pair cabling using RJ-45 connectors.
