Manual for GeniuX 4
Narrow SCSI
Narrow SCSI interface uses an 8-bit bus and a 50-pin connector. It supports Ultra narrow
SCSI peripherals and supports data transfer rate of 20MB/S. Be sure the red side of the cable
is aligned with the end of the connector which is marked with “ ”
Wide SCSI
Wide SCSI interface uses a 16-bit bus and a 68-pin connector. It supports Ultra Wide SCSI
peripherals and supports data transfer rate of 40MB/s.
Ultra 2 SCSI
Ultra 2 SCSI interface use a 16-bit bus and a 68-pin connector. It supports Wide Ultra2 SCSI
peripherals and supports data transfer rate of 80MB/S. Please note:
1. Ultra Wide SCSI HDDs can be connected to either Wide SCSI connector or Ultra 2
SCSI connector. In both ways the data transfer rate is 40MB/S.
2. Ultra 2 SCSI HDDs can also be connected to either Ultra 2 SCSI connector or Wide
SCSI connector. Supports the data transfer rate of 80MB/S only when connect-
ing to Ultra 2 SCSI connector. If connecting to Wide SCSI connector, the data trans-
fer rate is 40MB/S
3. If an Ultra wide SCSI HDD is connected to Ultra 2 SCSI channel, and all other HDDs
connected are Ultra 2 SCSI HDDs, the data transfer rate supported will be 40MB/
S for all.
