Installing the SYM8953U Host Adapter
You can connect up to four devices if they are evenly spaced on a
3-meter Ultra SCSI cable (0.75 m between devices). Your SE SCSI bus
should not exceed 3 meters (total internal and external cable lengths),
even with fewer than four devices.
For LVD applications, you can connect up to 16 devices including the
host adapter if they are evenly spaced on a 12-meter Ultra SCSI cable
(0.19 m minimum between devices).

1. This parameter may be exceeded in point-to-point and engineered
applications.
2. Additional spacing rules apply.
3. SE and high power differential are not defined at Ultra2 speeds.
