RN 6 provides termination for the SCSI interface lines. (Active termination is recommended when multiple drives are used.) Default is RN6 installed. SCSI terminators are installed only in the end devices on the SCSI cable; remove them from each of the other devices.
W1 and W2 select the source of power (+5V) for terminators RN1 and RN2; W12 controls the drive supplying +5V to the bus.
W1 W2 W12
Y N - Drive provides terminator power. (Default) N Y - Host provides terminator pwr via J1 pin 26 to RN6.
- - Y Drive supplies +5V to the bus via J1 pin 26. (Default)
Jumpers at J2 pins 7 and 8 controls the spindle option.
No Jumper The drive starts the spindle motor at power-on. (Default) Jumper The drive waits for a Start Unit SCSI command to start the motor.
A jumper at J2 pins 11 and 12 selects the write protect option.
Jumper The drive is write protected. No Jumper The drive is not write protected. (Default)
A jumper at J2 pins 13 and 14 selects the bus parity check option. The drive always generates parity regardless of this option.
Jumper SCSI interface parity checking disabled. No Jumper SCSI interface parity checking on. (Default)
Jumpers at W8 and W9 control spindle sync termination. This depends on system configuration; i.e. Master Mode or Master Controller Mode.
W8 W9 Yes Yes Slave and Master Sync are terminated. No No Spindle sync not terminated. (Default)
A jumper at W11 selects the frame ground option.
Jumper Frame ground connected to logic ground. No Jumper Frame ground not connected to logic ground. (Default)
