3. HARDWARE SETUP 6) Two 68-pin Ultra160 SCSI Connectors (SCSI-A, SCSI-B) This motherboard has two 68-Pin Ultra160 SCSI connectors; one for each of the two channels. Each channel can support a maximum of 15 devices as specified by Ultra160 standards. 34 1 68 35 68-Pin Ultra160/Ultra2-Wide SCSI Connector SCSI-A (Internal) 1 35 3.

The onboard SCSI chipset incorporates an advanced multimode I/O cell that supports both single-ended (SE), Ultra2, and Ultra160 devices. With Ultra160 devices, the SCSI bus platform performs at full Ultra160 speeds (up to 160MB/sec) 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. IMPORTANT: Connect SCSI devices as shown. Each channel should have only one type of SCSI standard (e.g. 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 A Internal SCSI Devices (up to 15 devices) 68-pin Female Terminator 68-pin Internal SCSI Cable (Twisted-Pair Ribbon) Channel B TR-DLSR TR-DLSR SCSI Connection Example Internal SCSI Devices (up to 15 devices) 68-pin Female Terminator NOTE: Ultra160 SCSI devices do not have termination jumpers and must use a separate terminator on the last connector (internal) or device (external). 32 ASUS TR-DLSR User's Manual
