Quantum Atlas 10K II Ultra 160/m SCSI Hard Disk Drives 3 − 11
3.4.1.5 Enable Narrow Mode (Force 8) (Disk Drives with 68-Pin SCSI
Connector)
Wide Data Transfer (WDTR) negotiations can be limited to 8-bit responses either by
setting the Force 8 bit of the Quantum-Unique Page (39h) of the MODE SELECT
command (15h) to 1, or by installing a jumper on pin pair 23 / 24 of the Secondary
Option Connector (Figure 3-4).
3.4.1.6 Remote Busy and Fault Displays (Disk Drives with 68-Pin SCSI
Connector)
Busy and Fault status of the drive can be monitored remotely by connecting a remote
(external) Busy and/or remote Fault display LEDs to the appropriate pins on the 12-
pin Option Connector or the 28-pin Secondary Option Connector.
Remote Busy LED
On the Option Connector, connect the cathode side of the remote Busy LED to pin
8, Busy LED (Figure 3-4). Connect the anode side of the LED to pin 11, +5V.
On the Secondary Option Connector, connect the cathode side of the remote Busy
LED to pin 18, Busy LED (Figure 3-4). Connect the anode side of the LED to pin
17, +5V.
Remote Fault
On the Option Connector, connect the cathode side of the remote Fault LED to pin
2, Fault LED (Figure 3-4). Connect the anode side of the LED to pin 11, +5V.
On the Secondary Option Connector, connect the cathode side of the remote Fault
LED to pin 9, Fault LED (Figure 3-4). Connect the anode side of the LED to pin 17,
+5V.
