Detailed Installation Procedure 2-7
All external SCSI bus connections to the SYM22801 host adapter are
made with shielded, 68-conductor cables (see Figure 2.3). The
connectors on this cable are always keyed to ensure proper pin-1
connection.

Important: You can connect up to sixteen SCSI and Fast SCSI
devices, including the host adapter board, on a single-
ended SCSI bus only if they are at least .3m apart on a 6
meter cable. For Ultra SCSI, you can connect up to eight
devices, including the host adapter board, on a
single-ended Ultra SCSI bus only if they are evenly spaced
on a 1.5 meter Ultra SCSI cable (0.19m between devices).
You can connect up to four devices if they are evenly
spaced on a 3 meter Ultra SCSI cable (0.75m between
devices). Your single-ended SCSI bus should not exceed
