[. . . ] We recommend the following part numbers: AMP Berg Electronics 499496 66900-040 Dimensions are in inches 0. 100 ± 0. 010 0. 70 ± 0. 010 0. 235 ± 0. 025 0. 230 ± 0. 003 0. 025 ± 0. 002 0. 025 ± 0. 002 0. 160 1. 90 2. 00 0. 100 typ 0. 070 ± 0. 010 Figure 3. The drive interface connector 2. 3 Power connector The drive comes with a standard 4-pin power connector. 2. 4 Master/slave jumper block The master/slave jumper block allows you to configure the drive for operation. Figure 4 on page 18 shows the master/slave jumper block configuration options. A brief description of each option is follows the drawing. A spare jumper is attached in a neutral position on pins 1 and 3 by the factory. The jumper block accepts 2-mm (0. 079-inch) jumpers. If you need additional jumpers, use Seagate part number 10562-001 or an equivalent. If you use a jumper that is not the correct size, you may damage the jumper block and the jumper. 18 Medalist 630xe and 850xe ATA Product Manual, June 1996 1357 2468 Spare jumper 1357 Single drive or Master with an ATA-compatible slave The drive is the slave Master with a non-ATA-compatible slave Cable select 2468 Figure 4. Master/slave jumper block settings 2. 4. 1 Single-drive or master with an ATA-compatible slave This is the factory default configuration (the jumper place on pins 1 and 3 is a spare and does not affect drive operation). The drive operates as a single drive on the controller or as the master drive with an ATA-compatible slave. 2. 4. 2 The drive as slave To make the drive the slave, attach the jumper to pins 7 and 8. 2. 4. 3 Master with a non-ATA-compatible slave This setting allows you to configure the drive to work with some slaves that do not conform to the DASP­ timing parameter of the ATA specification. When a jumper is placed on pins 5 and 6, the drive assumes a slave is present and ignores the initial DASP­ signal. The slave must return the PDIAGS­ signal. 2. 4. 4 Cable-select configuration To configure the drive for computers that use cable select (CSEL), place the jumper on pins 3 and 4. The interface cable must be designed for cable-select interconnection. The cable construction determines whether the drive is the master or the slave. Medalist 630xe and 850xe ATA Product Manual, June 1996 19 Slave CSEL not carried to pin 28 of this connector Master Pin 28 grounded at computer Computer Figure 5. Connecting cable-selected drives 2. 4. 5 Factory-test configuration Do not install jumpers on pins 5 and 6 and pins 7 and 8 at the same time. This configuration is used to test the drive at the factory. When jumpers are installed in both of these positions, the heads continuously seek back and forth across the media and the drive ignores all control signals sent through the interface. 2. 5 Mounting the drive You can mount the drive in any orientation using either the bottom or the side mounting holes as described below. Figure 6 on page 20 shows the drive dimensions and mounting holes. Insert four mounting screws not more than 0. 20 inches (6 full turns) into the drive frame. Insert four mounting screws not more than 0. 13 inches (4 full turns) into the drive frame. To prevent damage to the drive: · Use only mounting screws of the correct size and length. · Lightly tighten the mounting screws--do not apply more than 6 inch-pounds of torque. 20 Medalist 630xe and 850xe ATA Product Manual, June 1996 Figure 6 shows the dimensions in inches. 0. 15 ± 0. 01 Six #6-32 UNC-2B mounting holes 1. 000 max 2. 362 ± 0. 010 4. 000 ± 0. 010 0. 630 ± 0. 025 0. 250 ± 0. 010 0. 030 5. 77 max 2. 375 ± 0. 025 1. 75 ± 0. 010 3. 750± 0. 030 Four #6-32 UNC-2B mounting holes Figure 6. [. . . ] However, instead of generating interrupts to transfer each sector, interrupts are generated to transfer blocks of sectors as defined by the Set Multiple Mode command. The Set Multiple Mode command is used to determine the number of sectors that constitute a transferable block. It must be executed before the Write Multiple command. When the Write Multiple command is issued, the Sector Count register contains the number of sectors (not the number of blocks or the block count) requested. [. . . ]
