System with master and slave devices and ID number setting method of the slave devices

Abstract

The invention relates to the technical field of communication, and discloses a system with master and slave devices and an ID number setting method of the slave devices. According to the system with the master device and the slave devices and the ID number setting method of the slave devices, the master device included in the system can automatically set the ID number of each slave device in sequence according to the cascading sequence of the multiple slave devices. When the slave devices are mounted or replaced, a user does not need to manually distinguish and set the slave devices; therefore, the convenience for a user to install or replace the slave devices can be greatly improved, the setting error caused by the fact that the user manually distinguishes and sets the slave devices is avoided, and the problems that in the prior art, when a system is used for installing and replacing the slave devices, operation is tedious, and errors are prone to occurring are solved. Because a new slave device can be directly cascaded behind the last existing slave device, the expansion is convenient. And a dial switch does not need to be arranged on the slave devices, so that the cost of the slave devices and the complexity of the circuit are reduced.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a system with master and slave devices and a method for setting ID numbers of slave devices. Background technique [0002] In the prior art, some media processing systems such as copiers, printers, printing, scanning, and stamping integrated machines, as well as storage systems such as express cabinets and material cabinets, include a master device and multiple slave devices. Each slave device sends control commands and receives response commands sent by multiple slave devices. For example, in a media processing system, it includes a media processing device as a master device and a plurality of paper cassettes as slave devices, each paper cassette is used to accommodate a type of medium, the medium can be paper or bills, paper The box includes an opening for outputting the medium, the media processing device includes a conveying channel for conveying the medi...
