## Abstract

In the information processing system, the user can easily grasp the names of terminals that the main information processing device possesses. By transmitting the name data showing each name of multiple terminals 13, 14, 15 that the main information processing device 4 has to the control device 2 via the predetermined communication means 8, 11, and displaying each name of each terminal that said name data shows on the display means 33 of the control device 2, the user can easily grasp names of terminals that the main information processing device 4 has.

## Claims

### Claim 1

An information processing system comprised of a main information processing device controlled by a control device through a communication means, and sub-information processing devices connected to said main information processing device, said communication means being a serial bus, said main information processing device being an amplifier, and said control device being a computer; wherein:
said main information processing device comprises:
a plurality of terminals for connecting to a plurality of sub-information processing devices with a corresponding plurality of connecting means;
at least one of said connecting means being said communication means;
memory means for memorizing name data indicating names of said terminals; wherein said memory means changes the name data indicating the names of said terminals in accordance with a user's input operation,
wherein the name data includes unique manufacturer and chip numbers; and
name data transmission means for transmitting said name data to said control device through the communication means; and
said control device comprises:
name data receiving means for receiving said name data which is transmitted from said main information processing device through said communication means; and
display control means for displaying the names of said terminals on the display means based on said name data.
