CCTALK Communication Protocol
ccTalk®
communication protocol is the Money Controls serial communication protocol for low speed control networks.
It was designed to allow the interconnection of various cash handling devices (
Hoppers, Bill validators, Coin selectors
etc
.), mostly in AWP and gaming Industry, but allso in other devices that use those components.
cctalk®
is an open standard. All documentation is available at web site:
www.cctalk.org
.
6. Serial cctalk communication (English language)
New generation of coin selectors AL55 or AL66 use
cctalk®
communication protocol. This protocol was developed by
company Emulator M (ex. Coin Controls) to enable connection of different peripheral devices (Coin selectors,
Hoppers(
pay out device
), Banknote readers etc.) in small network.
Protocol is mostly used in gaming and casino machines but it can be implemented in any other tipes of machines that
use same type of devices. It is public protocol and free to use. Pls. find documentation on: www.cctalk.org.
Communication protocol of ALBERICI coin selectors AL55I66 complies with generic specification 4.4
6.1
Communication specifications
Serial communication was derivated from RS232 standard.
It is low data rate NRZ (
N
on
R
eturn to
Z
ero
) asyncronous communication with:
Baud rate 9600, 1 start bit, 8 data bits, no parity, 1 stop bit.
RS232 handshaking signals (
RTS, CTS, DTR, DCD, DSR
) are not suported.
Message integrity is controled by means of checksum calculation.
6.1.1
Baud rate
The baud rate of 9600 was chosen as compromise betwen cost and speed.
Timing tolerances is same as in RS232 protocol and it should be less than 4%.
6.1.2
Voltage level
To reduce the costs of connections the “Level shifted “ version of RS232 is used.
The idle state on serial connector is 5V, and active state is 0V.
Mark state (
idle
) +5V nominal from 3.5V to 5V
Space state (active) 0V nominal from 0.0V to 1.0V
Data I/O line is “open collector” type, so it is possible to use device in systems with different voltages.
6.1.3
Connection
The connection of Coin selector to network is achieved by means of 4 pole JST connector (
standard type 7
). Connector
is used for power supply and communication as well. For schematics and and connector appirance see image1.
Image 6.1 communication connector
Recommended periferal connector is:
JST B 4B-XH-A with crimping contacts SXH-001T-P0.6
6.2
Message structure
Each communication sequence consists of two message string.
Message string in case of simple checksum use is structured as follows:
[ Destination address ]
[ Nr. of data bytes ]
[ Source address ]
[ Header ]
[ Data 1 ]
...
[ Data n ]
[ Checksum ]
