fq040517-01 - How Do I Access the SCSI Wide E-Disk® Flash Drive in the E-Disk® VME Plug-In Module?


QUESTION:

How Do I Access the SCSI Wide E-Disk® Flash Drive in the E-Disk® VME Plug-In Module?

ANSWER:

There are two ways to access the SCSI flash drive:
  • from the 68-pin VHDC front panel connector; and/or
  • from the plug-in module P2 connector attached to the VME back plane
The E-Disk VME SCSI Wide card is compatible with the Dy 4 Systems SVME/DMV-181 Power PC 7410 SBC that is wired according to Force Computers’ VME products. The P2 connector pin outs are defined in Table 2.
