In multiple SCSI device configuration, it is necessary to configure each device with a priority. The priority identification for each drive is determined by the three binarily weighted ID jumpers. An ID of 7 is the highest priority in a multidevice configuration. JP7 Write Protect ------------------ CLOSED Data cannot be written to the drive, only read opera- tions can be executed. x OPEN Allowing normal reading and writing. JP8/JP16 Spin On Power/Delay/Command ------------------------------------- JP8 OPEN JP16 OPEN With both jumpers removed (OPEN) the drive will not spin-up until the Host issues a Start/Stop command (1BH) with the Start Bit = 1. JP8 OPEN JP16 CLOSED With JP8 removed (OPEN) and JP16 installed (CLOSED), the drive spins-up after exhausting a 13 second per SCSI ID delay. JP8 CLOSED JP16 OPEN With JP8 installed (CLOSED) and JP16 removed (OPEN), the drives spins-up immediately when power is applied. JP10/JP11 Terminator Power --------------------------- JP10 OPEN JP11 CLOSED The terminator power is external from the SCSI bus. JP10 CLOSED JP11 OPEN x The terminator power is internal from the drive. JP15 SCSI bus parity --------------------- x JP15 CLOSED Enables odd parity detection. OPEN Disables odd parity detection. As shipped from the factory the XT-3000 detects parity. Odd parity is always generated. ********************************************************************** I N S T A L L ********************************************************************** MAXTOR XT-3000 OEM MANUAL 1011005 REV. C Interface Termination --------------------- As shipped, all assigned interface signal lines are terminated with a removable 220/330 ohm resistor network. The first device and the last device on the daisy-chain SCSI bus must be terminated. Remove the terminators from any devices in between. For instance, if the XT-3000 is in the middle of the string, remove its terminators. Any host adapters beeing used should be terminated in a similar fashion. The devices driving the drive inpute should be open collector devices capable of sinking at least 48 milliamps at a voltage level of less than 0.5 VDC (7438 or equivalent). Devices receiving the drive outputs should be of "SCHMITT" trigger type to improve noise immunity, 74LS14, 74LS240 or equivalent. The host adapter should not load the bus with more than one standard LSTTL input load per line, and should terminate the drive output signals with 220/330 ohm terminators. ********************************************************************** F E A T U R E S ********************************************************************** MAXTOR XT-3000 OEM MANUAL 10111005 REV.
