Introduction 1 DATA EXPRESS® DE90 General Description The Kingston Technology Data Express® DE90 is a removable lightweight drive carrier and receiving frame designed to provide durable and reliable mounting for 3.5” SCSI or AT/IDE drives within 5.25" half-height peripheral slots (Figure 1).
2 Introduction The Receiving Frame Front Panel • The Key Lock/Drive Power Switch performs three functions. The key lock assures proper seating of the device carrier within the receiving frame, it turns power to the device carrier on and off, and it prevents unauthorized removal or installation of the carrier. For the computer to access data on the Data Express disk drive, the key must be turned counterclockwise to the locked position.
Introduction 3 The Receiving Frame Rear Panel (Refer to Figure 3) • DC Power Connector (J1): The Data Express uses a standard 4-pin Molex Disk Power Connector to accept DC power. • I/O Connector (J2): The input/output connector provides a standard interface for all SCSI signals. See Table 4 for J2 pin assignments. • ID Select Pins (J4): Pins 1 through 14 are reserved. Pins 15 through 20 of this connector provide unit SCSI ID selection for the computer system or expansion chassis.
4 Introduction Data Express Model Numbers The Data Express is available in both SCSI and AT/IDE models. Below is a part number schema of all currently available DE90 models. Receiving Frame and Carrier Combination DE90i - _ A = AT/IDE interface S = 8-bit single-ended SCSI interface 0414 Packaging Materials The Kingston Technology Data Express system is shipped in a container designed to provide protection and prevent damage during shipment.

Installation 7 DATA EXPRESS INSTALLATION Installing the Drive in the Carrier Preparation While performing the steps in this section, work on a soft surface to prevent excessive shock to the drive being installed. Also refer to the manufacturer's documentation provided with the drive. NOTE: A #2 Phillips screwdriver will be required during this procedure. 1. Remove the drive from its protective packaging. 2.
8 Installation NOTE: SCSI units are provided with a single row 3-pin wire wrap connector. This connector allows fabrication of ID select cable connections for use in confined areas or for drives which have nonstandard pin configurations. For example, drives with side mounted ID select pins will require the use of the wire wrap connector in place of the standard ID select cable.
Installation 9 Figure 5 illustrates a typical SCSI ID select connection to a drive with 2mm ID select pins. Attach the ID select cable to the drive using the 2mm connectors. Align the “ID0” pin with the black wire. Attach the 1.25mm connector on the other end of the ID select cable to the 1.25mm connector (J3B) provided on the signal distribution board, located inside the carrier. Refer to the manufacturer’s documentation to disable termination on the drive.
10 Installation The Quantum ProDrive LPS 270/540S (Figure 6) uses 1.25mm ID select pins. Connect the 1.25mm ID select cable connector to the drive ID select pins. Attach each of the 2mm connectors on the other end of the ID select cable to the 2mm connectors (J3A) provided on the signal distribution board, located inside the carrier. Align the “ID0” pin with the black wire of the cable. Refer to the manufacturer’s documentation to disable termination on the drive.
Installation 11 Installing the Receiving Frame The drive should be installed into the carrier before installing the receiving frame into the mounting bay of a computer or expansion chassis. NOTE: Use a #2 Phillips screwdriver during this procedure. 1. Turn off power to the computer. 2. Open the computer system according to the manufacturer’s instructions. If necessary, temporarily remove any expansion boards that may make installation difficult. 3.
12 Installation 4. To select the Data Express unit ID remotely through the computer system or external expansion chassis, the appropriate cable from the system must be connected to the ID select connector (J4) on the rear of the receiving frame as shown in Figures 5 and 6.
Installation 13 7. To connect the drive to a Remote Activity LED in the computer system or expansion chassis, connect the appropriate cable(s) to the receiving frame mother board as shown in Figure 3. Connect J6 Pins 4 and 6 to a remote activity LED. 8. Connect the I/O interface cable from the host adapter to the receiving frame. The pin 1 indicator on the cable must be properly aligned. Refer to Figure 3 for the correct pin 1 location. Make sure that only the last SCSI device is terminated.
14 Installation SCSI Interface Connector J2 The SCSI interface connector (J2) pin assignments are supplied for your convenience. All odd numbered pins, except pins 25 and 29 must be connected to ground. Pin 25 should be left open. Pin 29 can be used for Synchronized Spindle operation. Pin 26 is reserved for terminator resistor power source.
Appendix A - Attaching the On/Off Key 15 Appendix A - Attaching/Removing the On/Off Key The DE90 comes from the factory with a power/lock key which can be attached to the locking mechanism. Follow the steps below to attach the key. A B C 1. Make certain power is off to the receiving frame. Access Hole Pawl Key/Lock Locate the rectangular shaped key/lock mechanism access hole on the inside of the receiving frame. Note that the pawl is in an upright position. Insert the key into the lock.
