Installation

DiamondMax10 80/100/120/160/200/250/300GB AT 3-7

Once you install the CS jumper, the drive is configured as a Master or

Slave by the state of the Cable Select signal: pin 28 of the ATA bus

connector. Please note that pin 28 is a vendor-specific pin that Maxtor

is using for a specific purpose. More than one function is allocated to

CS, according to the ATA CAM specification (see reference to this

specification in Chapter 1). If pin 28 is a 0 (grounded), the drive is

configured as a Master. If it is a 1 (high), the drive is configured as a

Slave. In order to configure two drives in a Master/Slave relationship

using the CS jumper, you need to use a cable that provides the proper

signal level at pin 28 of the ATA bus connector. This allows two drives

to operate in a Master/Slave relationship according to the drive cable

placement.

The DiamondMax10 80/100/120/160/200/250/300GB AT hard disk

drives are shipped from the factory as a Master (Device 0 - CS jumper

installed). To configure a drive as a Slave (Device 1- DS scheme), the

CS jumper must be removed. In this configuration, the spare jumper

removed from the CS position may be stored on the PK jumper pins.

3.3.1.2 Drive Select (DS) Jumper

You can also daisy-chain two drives on the ATA bus interface by using

their Drive Select (DS) jumpers. To use the DS feature, the CS jumper

must not be installed.

To configure a drive as the Master (Device 0), a jumper must be installed

on the DS pins.

Note: The order in which drives are connected in a daisy chain

has no significance.

3.3.1.3 Master Jumper Configuration

In combination with the current DS or CS jumper settings, the Slave

Present (SP) jumper can be implemented if necessary as follows:

Note: The CS position doubles as the Slave present on this

drive.

• When the drive is configured as a Master

(DS jumper installed

or CS jumper installed, and the Cable Select signal is set to

(0), adding an additional jumper (both jumpers DS and CS now

installed) will indicate to the drive that a Slave drive is

present. This Master with Slave Present jumper configuration

should be installed on the Master drive only if the Slave drive

does not use the Drive Active/Slave Present (DASP–) signal

to indicate its presence.
