ARCNET®
PCI20 Series

selection guide of the PCI20 series.

The PCI20 Series of network interface modules (NIMs) interfaces ARCNET with PCI bus computers. The high performance PCI bus allows for jumperless configuration or plug and play operation.

The PCI20 inncorporates the newer COM20020 ARCNET controller chip with enhanced features over the earlier generation ARCNET chips. New performance and integration enhancements include command chaining operation and an internal 2K x 8 RAM buffer. There is no requirement for wait-state arbitration.

Each PCI20 module has two LEDs on the board. The green LED indicates that the module is transmitting data on the network and the yellow LED indicates bus access to the module. The PCI20 also has an external DIP switch so that node addresses can be easily reassigned without removing the module.

Several versions of the PCI20 ARCNET NIM exist. The PCI20-CXS supports coaxial star configurations requiring external active or passive hubs. The PCI20-CXB supports coaxial bus configuration usually requiring no hubs. Other models include the PCI20-FOG which supports fiber optic cable with either ST or SMA connectors. The PCI20-TB5 supports twisted-pair bus cabling using RJ-45 connectors. There are some versions that support EIA-485 communication each using RJ-45 and screw terminal connectors.
