Applied Data Sciences / PCIHSD2®
High Speed Data Link between a PCI bus HOST and the Encore HSD

The PCIHSD2 board is a new enhanced version of the industry proven PCHSD2®. The PCIHSD2 is functionally compatible with the PCHSD2 providing a PCI bus controlled emulation of the Encore HSD II board.

The transfer rate between the PCIHSD2's HSD port and the external device's HSD port are in excess of 10MBytes/second. The transfer rate between the PCIHSD2 board and the PCI bus is dependent upon the host system configuration and tasks in progress.

The PCIHSD2 is a minor re-design of the PCIHSD. The PCIHSD2 has a new type connector for connecting to the external HSD device. This new connector eliminates the need for the old J1 adapter board. The ribbon cables connect directly to the PCIHSD2. The PCIHSD and the PCIHSD2 are electrically identical. The only difference is the rear edge connector on the board. The spec sheet for the PCIHSD2 is identical to the PCIHSD except the PCIHSD2 does not have a J1 Adapter Board for connecting the ribbon cables.

Software Support:

Drivers are available for Linux v2.4.x & v2.6.x kernel, Windows NT/2000/XP and SGI IRIX 6.5. The PCIHSD2 comes with a Microsoft C, FORTRAN or PASCAL compatible relocatable object code device driver that is used to control the board. It is written for DOS version 3.1 or higher. There are 7 separate subroutines:

  • PCIOPEN: installs the driver in the DOS interrupt structure and initializes the data structures.
  • PCISTRT: starts a data transfer.
  • PCITEST: waits for completion of a NOWAIT operation.
  • PCITERM: terminates any existing transfer in progress.
  • PCICLOS: restores the DOS interrupt structure back to its normal configuration.
  • PCIMODE: set or change PCIHSD2 operating mode.
  • PCISTAT: read PCIHSD2 status.

Optional File Transfer software is available.
