3 Interface Cards
SCSI Adapter Card
•
Provides data reliability and cable distance of differential SCSI without
cost of external differential transceivers.
•
Improves connectivity (up to 15 LVD Ultra 2 SCSI devices) and cable
lengths (up to 12 meters with Ultra 2 SCSI). Longer cables may be
possible in point-to-point connections.
•
Supports SCAM (SCSI Configured Automatically) Level 1 functionality.
PCI connector
•
One 32-bit universal connector (supports both 5 V and 3,3 V signaling).
•
Configured as a 7,5 W board (PRSNT1 and PRSNT2 grounded).
•
The SCSI Adapter Card sink current on the 5 V power supplies lines. The
3,3 V is supplied by an on-board regulator.
PCI Bus
•
Complies with PCI Specification 2.1.
•
Supports 32-bit, 33 MHz PCI Bus.
•
Supports PCI write and invalidate, read line and read multiple commands.
•
Functions as full 32-bit PCI DMA Bus Master.
•
Operates on 3.3 V or 5 V PCI buses.
Terminators
•
Three multi-mode SE/LVD active, auto-terminating terminators
•
Auto-termination: terminators are active when one of the tow connectors
is used. If both connectors are used at the same time, terminators will
automatically switch to high impedance mode.
•
The terminator will automatically detect the bus type (LVD or SE) and
switch to the right mode.
Flash memory
The flash memory stores the SCSI BIOS. Refer to
