SP0 OPEN (default) SP1 OPEN Spindle motor starts at power-on. SP0/SP1 Spindle Delay Option ----------------------------- SP1 CLOSED SP0 OPEN Spindle start-up is delayed based on SCSI ID (12 seconds per ID). SP1 OPEN (default) SP0 OPEN Spindle motor starts at power on. WP Write Protect Option ------------------------ WP CLOSED Drive is write protected. WP OPEN Drive is not write protected. (default) PTY Bus Parity Check Option ---------------------------- PTY CLOSED Drive neither generates nor detects parity. OPEN Drive generates parity and has parity detection enabled. (default) W1/W2/W3 Bus Termination Power Option -------------------------------------- W1 CLOSED (default) Drive provides terminator power. W2 CLOSED Host system provides terminator power (via J1). W3 CLOSED Drive provides terminator power (via J1) to the BUS. W4 Interface Termination ------------------------ W4 INSTALLED Drive provides termination for the interface lines; i.e., onboard termination is electrically enabled. x OMITTED Drive does not provide terminatiopn for the inter- face lines; i.e., onboard termination is electrically disabled. Remote LED ---------- Open Collector output - Used to drive a user-supplied LED to indicate the drive is active. ********************************************************************** G E N E R A L ********************************************************************** AV What is an AV Drive? -------------------- Today's demanding digital video and audio applications require disk drives to sustain a pre-determined minimum data transfer rate. Any interruptions in this data rate are detrimental to AV applications that require constant delivery of data at 30 frames per second minimum. In standard drives utilized for data processing requirements, the error correction and thermal calibration methods employed are not optimized for continuous delivery of data. These routine housekeeping tasks will procedure gaps in the data stream as long as 850 ms, resulting in jumps, gaps, and stutters in motion and sound when used in most AV applications.
