Diagram of Model 800 HSSI (SCSI-2) Interface Breakout Box Network Application
The drawing illustrates Daisy-Chained SCSI-2 peripherals, HSSI devices connected to the Model 800 HSSI (SCSI-2) Interface Breakout box.
The Model 800 HSSI (SCSI-2) Interface Breakout Box is a tool designed for use to monitor all signals of the SCSI-2 interface. It is simply inserted in series between SCSI interface devices to provide access to and monitoring of all data, timing, and control signals. 15 one-foot mini patch cords that plug into the test points on the box are provided to facilitate access to signals passing through between connected devices.
There are fifty numbered test points on the unit. They are connected directly to the 50 pins of both HSSI/SCSI-2 connectors. Test points serve as access points for signals that are being passed between connected devices. The mini patch cords allow easy access to the corresponding connector pin, which can in turn be connected to a scope probe, data analyzer, voltage meter, or other diagnostic instrument!
HSSI: High Speed Serial Interface
HSSI is a short distance communications interface that is commonly used to interconnect routing and switching devices on local area networks with the higher speed lines of wide area networks.
SCSI: Small Computer System Interface
SCSI is a hardware interface that allows for the connection of up to 15 peripheral devices to a single PCI board called a “SCSI host adapter”. SCSI uses a bus structure and functions like a mini-LAN connecting 16 devices, with the host adapter counting as one device.
Both ends of the cable use a 50-Pin male plug which can plug directly into the Model 800 (SCSI-2) HSSI Breakout Box
