| Jumper Configurations for RZ22 Drives
=====================================
7.6.1 Jumper Options (Version 1 Logic Module): There shall be four
jumpers available for configuration. Three of the jumpers E1, E2,
E3 shall be used to select the drive's SCSI ID. E4 shall be
removed, enabling parity. The drives shall be shipped from the
factory with E1, E2, and E3 installed; E4 shall not be installed.
The SCSI ID jumper configurations are defined as follows:
E1 E2 E3 DEVICE
OUT OUT OUT 0
IN OUT OUT 1
OUT IN OUT 2
IN IN OUT 3
OUT OUT IN 4
IN OUT IN 5
OUT IN IN 6
IN IN IN 7
7.6.2 Jumper Options (Version 2 Logic Modules): There are six jumpers
available for configuration: three of these jumpers (E1, E2, and
E3) are used to select the SCSI ID, while E4 (installed) disables
parity. Jumpers E5 and E6 are used to enable either the spindle
synchronization signal or the LED (at J4, pins 1 and 2). The drive
shall be shipped from the factory with the following jumper
configuration: E1, E2, E3, and E6 installed.
There are three removable SCSI terminators at RP1, RP2, and RP3.
The drive shall be shipped from the factory with these terminators
removed. See Figure 7 for the location of these jumpers.

| Jumper Configurations for RZ24 Drives
=====================================
7.6 Jumper Options:
There are four jumpers available for configuration. Three
E1, E2 and E3 are used to select the drive's SCSI ID. Jumper E4
if present is unused. The following Table defines the setting
for these jumpers.

IN IN IN 7
APPLICATION NOTE:
The drive should be powered on if the SCSI Bus to which it is
connected is expected to be functional. The Bus interface of this
device will cause low voltage levels on the SCSI Bus to which it is
attached if drive power is not applied.

| Jumper Configurations for RZ55 Drives
=====================================
7.6 Jumper Options:
There are nine jumpers available for configuration. Three of the
jumpers ID0, ID1, ID2 are used to select the drive's SCSI ID. The
following table defines the setting for these jumpers.
ID2 ID1 ID0 DEVICE

W11 IN SEE 8.2.3
W4 OUT PARITY ENABLED
W21 IN FRAME GROUNDING TO HDA
IDO IN SCSI ID
ID1 IN SCSI ID
ID2 IN SCSI ID
8.2.3 Terminator Power: Terminator power (TERMPWR) shall be supplied
through a diode to prevent the back-flow of power to the drive.
TERMPWR has the following characteristics:
Supply voltage: 4.0 VDC to 5.25 VDC
Minimum source drive capability: 800 mA
Maximum sink capability: 1.0 mA sink capability (except for
the purpose of providing power to
an internal terminator) with a 1 A
fuse or equivalent current
limiting device.
APPLICATION NOTE: Bus termination is required on the last physical
device connected to the SCSI Bus. The termination power is
controlled by three jumpers W1,W2, and W11. The sourcing of
terminator power is defined by the following chart.
Source of SCSI Source of Drive
W1 W2 W11 Bus Power Terminator Power
out out out none sourced none
out out in drive +5 VDC none
in out out none sourced drive +5 VDC
in out in drive +5 VDC drive +5 VDC
out in out none sourced bus +5 VDC
out in in drive +5 VDC bus +5 VDC
If jumpers W1 and W2 are out, the drive should not have any SCSI
bus terminators installed.

> -< RZ23 >-
Can you please post the source of this info ? (the para
numbers suggest that it is extracted from a manual).
Also, the later replies imply that there are some choices
available for where terminator and buss power should be sourced from,
I would like to refer to the manual for any rules or guidelines there
might be on making these choices. I'm thinking of getting a CD drive
but don't want to spend a lot, so its likely to come "bare bones",
i.e. the >$250 ones that are advertised for the clone market.

You might do better to use RZSCSI::RZ$SPECS:. Deb (Deb F. Savoie - DFS)
