The modems of Telemetron system work on standard protocols MDB and EXE. Sales statistics is read using DEX / UCS and DDCMP protocols. Most vending machines and coin changers work with these protocols.
Currently, the modem is guaranteed to work with the following models of devices:
Desktop coffee machines
If your model of the machine or coin changer is not listed, check the protocol of your machine. Telemetron system will work on the following protocols:
MDB (Multi-Drop Bus) - a protocol that involves connecting all performing modules of the vending machine to a common wire that supports their logic. The main controller of the machine is the head unit, which sends commands on to other devices (coin changer, bill acceptor and cashless devices).
EXE (Executive, Protocol A) - a protocol developed by the company Mars Electronics International (MEI) to control the devices of vending machines. Transactions occur under the control of the coin changer, and the prices can be stored both in a vending machine mode (Standart mode), and in the coin changer itself (Price-Holding mode, if you need a more detailed history of the audit).
DEX / UCS (Direct Exchange / Uniform Communications Standard) - audit interface, which electrically corresponds to the levels and parameters of the RS-232. Transmits data of EVA-DTS fields, as well as the configuration of EVA-DTS, for example, transmits pricing information to a vending machine or payment device after collection of audit data.
DDCMP (DEC Data Communications Message Protocol) - this protocol is used to transmit EVA-DTS data.
Also you can send us the model of your machine, and we will check it for compatibility with the system.
