- WD1003V-SR1/SR2
-
- User Guide
-
-
- The WD1003V-SR1 controller is designed to interface with up to two
- Winchester hard disk drives with 2,7 RLL specifications in an IBM PC
- AT or compatible system and will support drives with up to 16
- read/write heads and 2048 cylinders. Each drive may be a different
- configuration.
-
- The WD1003V-SR2 also supports up to two floppy disk drives including
- 360 KB, 720 KB, 1.2 Megabyte, and 1.44 Megabyte drives (5-1/4 inch or
- 3-1/2 inch). The WD1003V-SR2 also supports "intelligent" 1.44
- Megabyte media drives. These intelligent drives obtain the drive
- type and data rate from the drive's media and do not depend upon the
- state of J1 pin 2 for this information.
-
- Installation of the controller requires three steps: 1) verifying
- jumper settings; 2) installing into the host computer; 3) formatting
- the hard disk drives. To complete installation, you will need the
- following:
-
- DO NOT USE WITH MFM TYPE HARD DISK DRIVES
-
- THE WD1003V-SR1 AND WD1003V-SR2 ARE TO BE USED WITH RLL DRIVES ONLY
-
- Two hard disk cables (3 if using 2 hard disk drives); Winchester RLL
- hard disk drive; screwdriver; MSDOS Version 2.0 or later; IBM
- Advanced Diagnostic diskette (or similar program for IBM
- compatibles); FDISK and Format utility (normally included with
- MSDOS).
-
- Preparation of Controller
-
- WARNING
- HANDLE THE CONTROLLER BY THE ENDS OF THE BOARD
- SOME OF THE CHIPS ARE STATIC SENSITIVE AND DAMAGE
- MAY OCCUR IF THE BOARD IS INCORRECTLY HANDLED
-
- Before you can install your WD1003V-SR1 or SR2, you will need to be
- certain that the jumpers (small shorting plugs) are correctly set.
- Refer to Table 1 for correct jumper settings. Modification of
- factory jumper settings is rarely necessary. Modify jumpers only
- under the direction of a qualified individual; i.e. your dealer.

- WARNING
- MAKE SURE COMPUTER IS TURNED OFF
- AND POWER IS DISCONNECTED
-
- 1. Verify that your host computer has a 135 watt power supply. If
- the disk drive(s) is(are) being installed internally, it is best to
- locate the controller in the nearest available expansion slot to the
- drive.
-
- 2. Remove the blank expansion slot bracket. Put the bracket away
- and save it for possible future use. The screw will be used to hold
- the new controller in place.
-
- 3. The terminating resistor must be present only on the last hard
- disk drive connected. If there are two drives, the terminating
- resistor must be present on the second drive. Verify proper setting
- of drive select switches for drive select 1 or 2. Refer to your
- system owner's manual for information about proper drive termination
- and select switches. DO NOT USE RADIAL SELECT OPTION.
-
- NOTE: IF USING THE WD1003V-SR2 WITH BUILT IN FLOPPY CONTROLLER...
-
- DO NOT ATTEMPT TO USE WITH ANY OTHER FLOPPY CONTROLLER. IT IS NOT
- POSSIBLE TO DISABLE THE FLOPPY CONTROLLER ON THE WD1003V-SR2.
-
- 4. Attach 34-pin control connector to J5 on the controller board.
- Make sure that Pin 1 of the cable connector goes to Pin 1 on the
- controller board. Pin 1 of the cable connector is typically located
- on the color coded side of the cable.
-
- 5. Connect control cable to drive.
-
- 6. Attach 20-pin data connector to J4 (Drive C or 0).
-
- 7. Attach 20-pin data connector to J3 (Drive D or 1).
-
- 8. Connect data cables to drives.
-
- 9. Attach Winchester activity LED connector to J6.

- FOR WD1003V-SR2 USERS:
-
- 10. Attach the floppy cable connector to J1.
-
- 11. Attach cable to floppy drive(s).
-
- NOTE: THE FLOPPY CABLE IS NOT THE SAME AS THE CABLE USED TO CONNECT
- THE HARD DISK DRIVES.
-
- 12. Install controller board into the expansion slot. Make sure that
- the board is seated properly by pressing down on both ends of the
- board. Secure the board with the bracket screw.
-
- CAUTION
- WHEN ROUTING CABLES, BE CAREFUL NOT TO PINCH
- THEM. CABLES MUST NOT GET CAUGHT BETWEEN THE
- COVER AND THE BOARDS, NOR SHOULD THEY OBSTRUCT
- ANY AIR FLOW PATH FROM FANS OR VENTS.
