SCSI cable is a kind of data cable used to establish high-speed connections and transfer data between minicomputers and peripheral devices such as printers, optical disks, and hard disks. The SCSI cable works on the basis of SCSI (Small Computer System Interface), which is a system-level interface standard for computers and their peripherals (such as hard disks, floppy drives, optical drives, printers, scanners, etc.).Different from VGA cable,the pins are samller and precision.

There are many types of SCSI cables, mainly depending on the location of the SCSI bus on the device and the type of connector. Common connectors include Centronics connectors, DB connectors, high-speed serial data connectors, and Telco connectors. Different types of connectors are suitable for different devices and environments, for example Centronics connectors are commonly used to connect most third-party peripherals, while Telco connectors are suitable for devices with up to 50 pins.Its functions are similar to vga to displayport or dvi to vga.
