I/O Interfaces COM1, keyboard/mouse, VGA, 10BaseT/100BaseTX, and PMC, all accessible through front panel
SCSI, COM2, LPT1, PMC I/O, and, optionally, IDE and FDC, routed to the P2 connector (PMC I/O and FDC are on rows d & z)
P2 Breakout Board Rear plug-in module
Routes all P2 I/O to standard connectors
DB-9 connector for COM2, DB-25 connector for LPT1, Ultra- SCSI connector, and floppy drive and IDE connectors
64-pin DIN connector for PMC I/O
Flat-ribbon headers also available for all I/O
Enables interface of all I/O in a single VME slot
Transition Module Requires one additional slot for a two-slot configuration with the DPC2, including floppy and hard drives
Includes front panel SCSI and COM2 connectors
Rugged/Extended Temperature Special thermal design allows extended temperature operation
Tested to -40°/+85°C operation
Use of surface-mount SDRAMs and no socketed components allows high shock/vibration immunity
Power requirements +5 VDC @ 4.4 A typ.
+3 VDC Lithium Coin Cell @ 2.4 mA
