Claims (1)

[Claims for Utility Model Registration] An interface logic that exchanges data, commands, and control signals between the SCSI bus and a first control logic; A device that sends and receives commands and control signals, a ring buffer type command memory that sequentially stores data and commands that are sent and received between the SCSI bus and the first control logic, and a command memory that sequentially stores commands and commands before and after timing error detection. a second control logic that controls the command memory so that data is saved; and an external communication that controls the second control logic and outputs the commands and data stored in the command memory to the outside. A SCSI standard device monitoring device comprising: an interface logic for use with the computer;
