An external terminator provides termination for the interface lines.
Suggested end-of-cable terminator: Methode DS2050-01-68D
If a jumper is installed at W1 (Default), the drive provides terminator power (TERMPWR) to the bus.
If the jumper is omitted, the host system provides TERMPWR.
A user-supplied LED may be connected to Remote LED (Pins 1 and 2).
Jumpers at SP0 (Pins 11 and 12) and SP1 (Pins 13 and 14) control the spindle options.
N N The drive starts the spindle motor at power-on. (Default) Y N The drive waits for a Start Unit SCSI command to start the spindle motor. N Y Spindle start-up is delayed based on SCSI ID address (12 seconds per ID)
A jumper at WP (Pins 15 and 16) selects the write protect option.
Jumper The drive is write protected. No Jumper The drive is not write protected. (Default)
A jumper at PTY (Pins 17 and 18) 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)
Use of the MSYNC and SSYNC signals is optional. These signals are used as spindle synchronization reference.
Note: J1A is sampled at initialization for jumpers on pins 7-8, 5-6, 3-4, and 1-2 for SCSI ID3, ID2, ID1, and ID0 respectively; these connections (if not jumpered) are then released for the following usages:
A dash character (-) at the end of a signal name indicates that it is asserted at the low level (i.e., active low) and negated at the high level.
Output signal negated (Default); indicates no drive fault.
Output signal asserted; indicates a drive fault condition.
Use is optional; used as spindle synchronization reference.
Open collector output; used to drive a user-supplied LED to indicate the drive is active.
Logic ground; provides signal ground.
5 VDC (1A max); used to drive external LEDs.
Input signal negated (Default); drive is not write protected.
Input signal asserted; drive is write protected.
