SCSI-3 MD68M (Thumbscrew) to SCSI-2 MD50M Cable
scsi-3 md68m（指旋螺钉）到scsi-2 md50m电缆
- 特征：
- Ultra SCSI（或SCSI-3）是最新的不断改进的SCSI标准，并且是诸如Iomega zip驱动器
- 它包括单端和差分总线型号的规格
- 单端类似于快速SCSI-2，除了它可以通过16位单线电缆总线寻址最多32个器件
- 这种风格还可在单端应用中提高高达20Mbps的数据吞吐量
- 单端SCSI-3限于4个设备超过3米或8个设备超过1.5米
- 差分SCSI是指每个信号使用两根导线的总线配置，信号由两根导线之间的电压差导出
- 这种方法有效地消除了SCSI总线上的噪声，并允许总线长度增加到25米
- 连接器1：微密度68公
- 连接器2：微密度50男
- Features:
- Ultra SCSI (or SCSI-3), is the latest of the ever-improving SCSI standards, and is the cable of choice for such peripherals as the Iomega zip drive
- It includes specifications for a single-ended as well as a differential bus style
- The single-ended is similar to fast SCSI-2, except that it accommodates addressing up to 32 devices over a 16-bit single cable bus
- This style also increases data throughput up to 20Mbps in single-ended applications
- Single-ended SCSI-3 is limited to 4 devices over 3 meters or 8 devices over 1.5 meters
- Differential SCSI refers to a bus configuration using two wires per signal, with the signal being derived by the voltage difference between the two wires
- This approach effectively eliminates noise on the SCSI bus and allows bus length to increase up to 25 meters
- Connector 1: micro-density 68 male
- Connector 2: micro-density 50 male
