Adjusting the Spin Down/Up Timer
NOTE: The timer for device spin down is controlled by a small selector, located in a cutout
on the side of the DE200 receiving frame as shown in Figure 11. The amount of
time required for a drive to spin down is approximately 15 seconds or more. This
number can vary depending on the type of SCSI device and manufacturer (some
drives may require 45 seconds or more). The factory configuration is set for 20
seconds. A different delay time may be selected with the provided alignment tool.
Refer to the SCSI device manufacturer’s manual for more information on required
device spin down time.

SCSI Interface Connector J2
The SCSI interface connector (J2) pin assignments are supplied for your convenience. All odd
numbered pins, except Pins 25 & 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.
