Abstract

The invention discloses a protocol switching device suitable for MDB / ICP bus serial connection payment module, including MDB master device, MDB slave device, MDB bus, MDB master device and MDB slave device are connected through MDB bus communication, and also include MDB The transfer box and the network module, the MDB bus, the MDB slave device and the network module are respectively connected to the MDB transfer box. On the basis of the traditional MDB equipment solution, the present invention connects the MDB transfer box on the original MDB bus and connects the network module to realize the transformation of the traditional MDB equipment into a network and online payment function. Keep the original offline payment function. Without changing the entire MDB equipment system, it can be transformed into a new type of equipment with networked payment function at the lowest cost.

Description

technical field [0001] The invention relates to a communication device, in particular to a protocol conversion device of a payment module. Background technique [0002] The standard of the MDB / ICP bus protocol (Multi-Drop Bus / Internal Communication Protocol) was first developed by Coinco under the designation of the Coca-Cola Company of the United States. This standard was adopted by the NAMA Association in 1993 and adopted by EVMMA in 1994 after adding some compatible instructions. The MDB interface is actually a master-slave serial bus interface working at a baud rate of 9600. The peripheral devices used, such as coin acceptors, banknote dispensers, and card readers, are all slaves of the host computer (VCM), that is, the vending machine controller. . All peripherals communicate with the kiosk controller in the same way. [0003] At present, the MDB / ICP protocol (Multi-Drop Bus / Internal Communication Protocol) is a protocol developed by the European Vending Machine Manu...
