SCSI, the full name of Small Computer System Interface, Chinese called: Small Computer System Interface. It is an interface that connects the host and peripherals, and supports a variety of devices including disk drives, tape drives, optical drives, scanners, servers and workstations, and industrial control equipment. At present, the main customer group is industrial control industry customers. SCSI cable manufacturers can choose TXGA, and insist on achieving professionalism with focus for 15 years, which is trustworthy.
The SCSI signal specification specifies the signal delay, small pulse width and hold time of the SCSI bus. But users do not have to worry about these, because the SCSI protocol chip will manage most of the timing constraints. SCSI's protocol chips include AIC-6250 of Adaptetc and 5380 and 539 of NCR, which use an interlocked symbol exchange method to send data to the entire bus. This communication protocol is based on the question and answer symbol exchange. The bus state of SCSI is called phases. There are a total of eight possible bus phases, except for one, the others all adopt asynchronous transmission.
In the data phase, information can be exchanged in one of two ways: synchronous or asynchronous. Synchronous transmission is only used when both the host computer and the target device allow it. Data is transferred to the entire bus in parallel one byte at a time on the bus, using eight data lines. The typical asynchronous transmission rate is about 2 megabytes per second, and the synchronous transmission rate can reach as high as 5 megabytes per second.
The versatility of SCSI has made it a standard in most companies' system-level and external memory device products. The SCSI standard cable can easily connect multiple peripheral devices, and its standard command set simplifies the system designer to purchase SCSI peripheral devices while ensuring compatibility. The TXGA SCSI cable has stable connection, fast transmission, and provides customized services. When you need a SCSI connector, you can contact TXGA.
