2.2.3 Connecting the SCSI Peripherals
SCSI bus connections to the SYM8953U host adapter inside your
computer can be made with an unshielded 68 conductor Ultra SCSI PVC
ribbon cable (see
Figure 2.3
). The lead connected to pin 1 on the cable
is marked with a colored stripe. The connectors on this cable may also
be keyed to ensure proper pin-1 connection.
All external SCSI bus connections to the SYM8953U host adapter are
made with high quality shielded 68 conductor cables (see
Figure 2.3
).
The connectors on this cable are always keyed to ensure proper pin-1
connection.
Note:
All the cables shown in
Figure 2.3
are included in the
Symbios Adapter Board Kit for the SYM8953U host
adapter.
You can connect up to eight SCSI, Fast SCSI, and Ultra SCSI devices
on a SE Ultra SCSI bus only if they are evenly spaced on a 1.5-meter
Ultra SCSI cable (0.19 m between devices).

Note: Absence of the word “Wide” means an 8-bit bus width. It is
acceptable to use the word “Narrow” to avoid ambiguity.
