Figure 5 : DE90i-A Carrier Circuit Board
NOTE: For dual, interchangeable drive configuration, the two drives must be of the same
make and model.
The appropriate signals from the drive must be connected to J3 on the carrier board. These
signals are used to enable the functions of the unit selection, as well as the front panel display,
and drive activity indicator light. A 3-pin wire wrap connector is provided to enable fabrication
of a cable (cable not included) from the AT/IDE drive to the DE90i-A carrier circuit board. Figure
5 illustrates the DE90i-A carrier printed circuit board.
Configuring Connector J3
The connector J3 has three (3) 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 be connected to the "Active" signal of the drive (optional). This signal
controls the level of the drive activity indicator light on the front panel of the
receiving frame.
