CcTalk implementation over simple async com port interface - vltgroup/ccTalk. The logic levels for the ccTalk line are 3.5 to 5V for mark state (idle) and 0 to 1V for space state (active). This allows a low cost interface width 5V microcontrollers. Some dedicated gaming PC based platforms like this one have one or more built in ccTalk ports. Simple 5V microcontroller interface.

ccTalk (pronounced see-see-talk) is a serial protocol in widespread use throughout the money transaction and point-of-sale industry. Peripherals such as the currency detectors for coins and banknotes found in a diverse range of automatic payment equipment such as transportation, ticketing, payphones, amusement machines, and retail cash management use ccTalk to talk to the host controller.

In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.

A currency detector or currency validator is a device that determines whether notes or coins are genuine or counterfeit. These devices are used in a wide range of automated machines, such as retail kiosks, supermarket self checkout machines, arcade gaming machines, payphones, launderette washing machines, car park ticket machines, automatic fare collection machines, public transport ticket machines, and vending machines.

The ccTalk protocol is one of 2 protocols specified by BACTA for use in all AWP machines with serial coin acceptors. (The other is the Host Intelligent Interface protocol developed by Mars Electronics International).^[1]:20

The protocol was developed at a company called Coin Controls (hence coin-controls-talk, later called Money Controls and from 2010 Crane Payment Solutions) on the outskirts of Manchester in north-west England mainly by Engineer Andrew William Barson. The first release of the protocol was in 1996.^[2]

Manchester is a major city and metropolitan borough in Greater Manchester, England, with a population of 545,500 as of 2017. It lies within the United Kingdom's second-most populous urban area, with a population of 2.7 million, and third-most populous metropolitan area, with a population of 3.3 million. It is fringed by the Cheshire Plain to the south, the Pennines to the north and east, and an arc of towns with which it forms a continuous conurbation. The local authority for the city is Manchester City Council.

England is a country that is part of the United Kingdom. It shares land borders with Wales to the west and Scotland to the north. The Irish Sea lies west of England and the Celtic Sea to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight.

The ccTalk protocol is an open standard.^[1]:13

The protocol uses an asynchronous transfer of character frames in a similar manner to RS232. The main difference is that it uses a single two-way communication data line for half-duplex communication rather than separate transmit and receives lines. It operates at TTL voltages and is ‘multi-drop’ i.e. peripherals can be connected to a common bus and are logically separated by a device address. Each peripheral on the ccTalk bus must have a unique address.

Two-way communication is a form of transmission in which both parties involved transmit information. Two-way communication has also been referred to as interpersonal communication. Common forms of two-way communication are:

The original protocol operated at 4800 baud with subsequent releases standardising on 9600 baud. Low cost bridge chips are now available from a number of manufacturers to allow ccTalk to run over USB at baud rates of at least 1 Mbit/s.

In telecommunication and electronics, baud is a common measure of symbol rate, one of the components that determine the speed of communication over a data channel.

ccTalk protocol stacks have been implemented on a range of devices from tiny Microchipmicrocontrollers with 512 bytes of ROM to powerful ARM7 32-bit processors.^[1]:12-13

An integrated circuit or monolithic integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material that is normally silicon. The integration of large numbers of tiny MOS transistors into a small chip results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block approach to circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones, and other digital home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs.

Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, sometimes known as firmware. Software applications for programmable devices can be distributed as plug-in cartridges containing read-only memory.

ARM7 is a group of older 32-bit RISC ARM processor cores licensed by ARM Holdings for microcontroller use. The ARM7 core family consists of ARM700, ARM710, ARM7DI, ARM710a, ARM720T, ARM740T, ARM710T, ARM7TDMI, ARM7TDMI-S, ARM7EJ-S. The ARM7TDMI and ARM7TDMI-S were the most popular cores of the family.

The protocol supports all standard operations for electronic devices such as flash upgrading of firmware, secure transfer of data and detailed diagnostic information.

Advantages of ccTalk include low cost UART technology, a simple-to-understand packet structure, an easily expandable command interface and no licensing requirements. The latter affords the protocol a good deal of popularity in a crowded and highly competitive field similar to open-source software.

In 2010, DES encryption was added to certain commands so that it could be made more resilient against attacks on the bus.^[2] Each peripheral has its own unique DES key.^[3][4]

The original ccTalk protocol did not use any kind of encryption. It was thought that the security in a serial interface was so much better than a parallel one that no. The ccTalk protocol is used to transfer information and commands to various money processing device, including coin/bill acceptors and coin. The OSI 7-layer network model is of limited use for a simple control protocol such as cctalk. Whereas the task of writing software for full-blown networking.
