Introduction 3 General Description The StorCase Technology Data Express® DE75i-A is a removable low-profile drive carrier and receiving frame. The Data Express is designed to provide durable and reliable mounting for 3.5 low profile AT/IDE drives within 5.25" half-height peripheral slots (Figure 2).
4 Introduction Receiving Frame Front Panel The Key Lock/Drive Power Switch performs three functions. The key lock assures proper seating of the drive carrier within the receiving frame, turns power to the drive carrier on and off, and prevents unauthorized removal or installation of the carrier. For the computer to access data on the DE75i-A drive, the key must be turned counterclockwise to the locked position.
Introduction 5 Receiving Frame Rear Panel DC Power Connector (J3): The Data Express uses a standard 4-pin DC Power Connector to accept DC power. I/O Connector (J7): The input/output connector provides a standard interface for all IDE signals. See Table 4 for J7 pin assignments. Master/Slave Selection (JP1 ID0-ID1): Master Drive configuration ID0 (default). Forces master drive configuration on receiving frame.
6 Installation INSTALLATION Installing the Drive into 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.
Installation 7 Figure 5: DE75i-A Drive Carrier Circuit Board The J3 connector has three pins: J3 Pin 1 should be connected to the Master signal of the disk drive. This signal indicates that this is the Master C: drive. J3 Pin 2 may be connected to the Slave/Slave Present signal of the drive. This signal indicates whether a Slave D: drive is present or not. J3 Pin 3 may optionally be connected to the "Active" signal of the drive.
8 Installation Table 1 shows the signal levels on J3 Pin 1 and Pin 2 for different W1, W2, and W3 jumper settings. Connections to J3 Pin 1 should be made with signals from the drive that refer to Master, while the connections to J3 Pin 2 should be made with signals from the drive that refer to Slave. Table 1: J3 Master/Slave Signal Levels * corresponds to a jumper installed on the carrier L (Low) corresponds to an installed jumper on the drive H (High) corresponds to a removed jumper on the drive.
Installation 9 If a slave drive is removed, Table 3 shows the signal levels on J3 Pin 1 and Pin 2 that will result for different W1, W2, and W3 jumper settings. Table 2: J3 Master (No Slave) Signal Levels * corresponds to a jumper installed on the carrier L (Low) corresponds to an installed jumper on the drive H (High) corresponds to a removed jumper on the drive.

10 Installation Figure 6: Typical AT/IDE Drive Connections Typical AT/IDE drive jumper positions are shown in Figure 6. C/D DSP The darkened pin in the figure above is connected to Pin-1 of the provided wire wrap connector. Install the jumper in the DSP position as shown in Figure 6. Install the wire wrap connector onto J3 on the drive carrier circuit board. StorCase Technology, Inc. DE75i-A User's Guide - Rev.
Installation 11 Installation 1. Attach the I/O cable on the drive carrier circuit board to the drive. Refer to Figure 7 for an illustration of the installation process. 2. Attach the 4-pin power cable on the drive carrier circuit board to the drive. If you are installing only one drive carrier, skip to Step 4. 3.
12 Installation Installing the Receiving Frame The drive should be installed into the carrier before installing the receiving frame into the mounting bay of the computer 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 manufacturers instructions. If necessary, temporarily remove any expansion boards that may make installation difficult. 3.
Installation 13 Figure 9: Receiving Frame Mounting Holes 5. Adjust the front of the receiving frame so the carrier slides freely in and out on the receiving frame guides. The position of adjoining peripheral units may require adjustment. 6. To connect the drive to a Remote Activity LED in the computer system, connect the appropriate cable(s) to the receiving frame rear panel as shown in Figure 4. Connect JP1 Pins 17 & 18 to a remote activity LED. 7.
14 Installation Selecting the Unit ID Number 1. Verify that power is turned on to the DE75i-A receiving frame by turning on the computer. A number should appear in the unit display window if the carrier is locked in place. 2. Unlock the DE75i-A drive carrier and remove it from the receiving frame. A "u" will be displayed initially when the unit is unlocked but will return to a number when the carrier is removed from the receiving frame.
Installation 15 Unit ID Select Switch Settings The following table lists the Unit ID Select Switch settings and the valid AT/IDE unit numbers. Please note that all invalid switch settings have X's and result in a blank display in the receiving frame display window.
16 Installation AT/IDE Interface Connector J7 The AT/IDE Interface connector (J7) pin assignments are as follows: Table 4: AT/IDE Interface Signals Pin 01 03 05 07 09 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 Signal Host ResetHost Data 7 Host Data 6 Host Data 5 Host Data 4 Host Data 3 Host Data 2 Host Data 1 Host Data 0 Ground Reserved HIOWHIORReserved Reserved IRQ 14 Host ADDR 1 Host ADDR 0 Host CS0DASP- I/O O I/O I/O I/O I/O I/O I/O I/O I/O O O I O O O Notes Pin 02 04 06 08 10 12 14 16 18 20 22 2
