Maxtor 300 manual Drive Select DS Jumper, Master Jumper Configuration

Page 22

Installation

Master or Slave with the CS feature, the CS jumper is installed (1). The drive's position on the 80 pin conductor Ultra ATA data cable then determines whether the drive is a Master (Device 0) or a Slave (Device 1). If the drive is connected to the end of the Ultra (cable Select) data cable the drive is a Master. If the drive is connected to the middle connection it is set as a Slave.

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 PATA 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 PATA 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 PATA bus connector. This allows two drives to operate in a Master/Slave relationship according to the drive cable placement.

The Quickview 300 PATA 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.

3.3.1.2Drive Select (DS) Jumper

You can also daisy-chain two drives on the PATA 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.

3.3.1.3Master Jumper Configuration

In combination with the current DS or CS jumper settings, the Slave Present (SP) jumper can be implemented if necessary as follows:

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.
