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.
Specify PCIHSD2, Part number: 0700615. Includes technical and user documentation, 20' cables,
DOS I/O routines & interactive test program, IRIX 6.5 driver, Windows NT/2000/XP driver, and Linux driver. All of the drivers and technical & user documentation are contained on a CDROM. You can E-mail us at sales@appdatsci.com or call us at 972-620-8530 for pricing information.
Save on host overhead - the PCIHSD2 has much lower overhead for networking or communication applications and is significantly faster than conventional ethernet.
Save money - continue to use your exiting HSD peripherals without having to make changes.
Save on installation time - simple to install and easy to use software I/O routines.
Save on repair and testing - fast and economical way to verify the integrity of an existing data link.
The PCIHSD2 host computer initiates all transfers with the HSD compatible external device. Once transfer begins, the PCIHSD2 executes and monitors the flow of control, status, and data between the host computer memory and the external device.
The host and external device, which is connected to the PCIHSD2, operate independently of each other. Transfers between the PCIHSD2 and the host are at the speed of the PCI bus. Control and status transfers are by I/O. Data transfers are by DMA or Programmed I/O. The transfer rate between the PCIHSD2 and the external device are dictated by the speed of the 32-bit transfers between the PCIHSD2 FIFO and external device.
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.
Installation of the PCIHSD2 is easy because the board configuration is software selectable. Just plug the PCIHSD2 into any PCI slot in the PC chassis. Then attach the 50-conductor ribbon cables to the Encore host or external device. Each PCIHSD2 comes complete with installation and programming instructions, and the supporting software includes software example programs for the Encore host. The PCIHSD2 is typically configured via software in one of the following ways.
PCIHSD to HSD Interface: One 100-pin hi-density latching connector on rear edge of board.
Cable: The cable harness attaches to the 100-pin latching connector located on the PCIHSD2 board. The other end of the cable has two 50-pin IDC female connectors that attach to the HSD device or Encore computer.
