There are several versions of the PCI20U ARCNET NIM. Three models sup-
port traditional ARCNET 2.5 Mbps di-pulse transceivers. The PCI20U-CXS
supports coaxial star or point-to-point configurations facilitated by the use of
active hubs. The PCI20U-CXB supports coaxial bus configurations while the
PCI20U-TB5 supports twisted pair bus configurations using RJ-45 connectors.
Both bus topology products usually do not require active hubs. Four models
also support EIA-485 networks and both standard mode and backplane mode
are supported. The PCI20U-485 (backplane mode) and PCI20U-485D (non-
backplane mode) support DC-coupled operation. The PCI20U-4000 (back-
plane) and PCI20U-485X (non-backplane) support AC-coupled operation.
