10. Two 68-pin Ultra160/320 SCSI Connectors (SCSI1, SCSI2) This motherboard has two 68-Pin Ultra160/320 SCSI connectors; one for each of the two channels. Each channel can support a maximum of 15 devices as specified by Ultra160/320 standards.

The onboard SCSI chipset incorporates an advanced multimode I/O cell that supports both single-ended (SE), Ultra2, and Ultra160/320 devices. With Ultra160/320 devices, the SCSI bus platform performs at full Ultra160/320 speeds (up to 160MB/s or 320MB/s) and extended cabling 12m (or 25m in a point-to-point configuration). When an SE device is attached, the bus defaults to an SE speed and 1.5m cable length. Connect SCSI devices as shown. Each channel should have only one type of SCSI standard (e.g. Ultra320, Ultra160, Ultra2, Ultra-Wide). Mixing SCSI devices on the same channel decreases performance of the slower device. 68-pin Internal SCSI Cable (Twisted-Pair Ribbon) Channel B PRL-DLS ® Internal SCSI Devices (up to 15 devices) 68-pin Female Terminator 68-pin Internal SCSI Cable (Twisted-Pair Ribbon) Channel A Internal SCSI Devices (up to 15 devices) PRL-DLS SCSI Connection Example 68-pin Female Terminator ASUS PRL-DLS motherboard user guide 2-25
