describes the signals for the SCSI Signals group.
Description
SCSI DIFFSENS signal. A low level
input enables SCSI SE mode. A
mid-range level input enables SCSI
LVD mode. A high level input enables
SFF-8067 Mode. Tie this pin to V
to enable SFF-8067 mode.
SCSI High ID 2. This LVD SCSI pair
may be connected to any of the SCSI
data signals from data bit 8 through
15. This provides the means for the
SCSI core to respond to selection as
a device with an ID greater than 7.
In SE mode, the SHID2 pin is the
SE signal pin, and the SHID2+ pin
should be connected as a virtual
ground on the SCSI connector.
SCSI High ID 1. This LVD SCSI pair
may be connected to any of the SCSI
data signals from data bit 8 through
15. This enables the SCSI core to
respond to selection as a device with
an ID greater than 7.
In SE mode, the SHID1 pin is the
SE signal pin, and the SHID1+ pin
should be connected as a virtual
ground on the SCSI connector.
SCSI High ID 0. This LVD SCSI pair
may be connected to any of the SCSI
data signals from data bit 8 through
15. This enables the SCSI core to
respond to selection as a device with
an ID greater than 7.
In SE mode, the SHID0 pin is the
SE signal pin, and the SHID0+ pin
should be connected as a virtual
ground on the SCSI connector.
