• 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. Change jumper to set slave
drive configuration, or remove jumper to use Unit ID Select Switch on receiving frame
(Figure 10 and Table 3).
• Activity Select (JP1 A-B): Default setting is "A" to use the activity indicator light
on the receiving frame. Set to "B" to use the drive activity light on the computer
chassis.
• Master/Slave Receiving Frame Interconnection (JP1 DPR): Used for older
model drives that do not support a "Slave Present" handshake signal at I/O connector
Pin 39. When using two receiving frames a connection between JP1 DPR may be
required.
• Remote Drive Activity (JP1 RLED): Pins 17 & 18 are used for remote drive activity.
