Master/Slave J2 Jumper Option on the Receiving Frame Mother-
board (Figure 3)
Master/Slave Selection Jumper (J2)
Master Drive configuration (Factory Default). Change jumper position to set
Slave Drive configuration.
Forces master/slave drive configuration on the receiving frame if JMP1
jumper option (located on the drive carrier circuit board) is configured to
Cable Select.
If using the Drive Select Method, this option is instead used to configure
the unit ID display (refer to Figure 4 for further information).
For 5.25” peripheral slots, the 5.25” adapter bracket must be installed. The
receiving frame is side-mounted into the adapter bracket using four (4) M3
Phillips Pan Head screws (provided).
With the drive carrier locked in place inside the receiving frame, install the
DE50 into the 5.25” drive opening in the computer or expansion chassis.
Use the appropriate guides to position the DE50 unit, and fasten it into
place with four (4) self-tapping screws (included). Mounting holes are pro-
vided on each side and the bottom of the adapter bracket to accommodate
a variety of mounting configurations. Use the mounting holes which best
suit the computer or expansion chassis configuration.
Unit ID Select Switches 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 shaded
boxes and result in a blank display in the receiving frame window.
NOTE:
The unit ID number display is for ID display purposes only (when
using the Drive Select Method). The master/slave setting must still be set
on the DE50 unit itself (refer to Page 1 for further information).
Selecting the Unit ID Number
Use the alignment tool (provided) to select the ID number of the disk drive.
NOTE:
The lock on the Data Express receiving frame functions as a
lock and a DC power switch for the carrier unit. The lock MUST be
engaged (turned counterclockwise) in order to supply power to the
carrier and installed drive unit.
