CC TALK is a serial communication protocol providing an excellent balance between easiness and
safe information. This protocol was designed for the GAMING industry.
It includes a high number of specific controls, aimed at meeting a high control flexibility by a control
unit called Host (Machine Data Sheet)
It was designed to allow the interconnection between different types of money treatment devices
simply with a serial cable, shown below.
The use of controls is free and according to the type of application and requirements; anyway all
strategies and supervision are carried out by the Host.
The type of connection is called Multidrop, where only the Host can “Ask”, all devices “Listen” and
only the adressed device “Responds”. Communication is of “half duplex” type, i.e. on the line there
is only the request or the answer, never both at the same time (full – duplex).
From 4 to 10’
The protocol provides no procedure to manage peripherals. This is left to the common sense of the
Host programmer. For example, if you want to avoid replacing the validator or any other device, it
may be sufficient that, when the machine is started up, this requests its peripheral about serial
numbers, product code, manufacturer code,etc. If all information received from the peripherals
matches the information stored in the host all activities can go on, otherwise these may be ihibited
and the necessary measures will be taken.
RM5 X CC implements 35 controls described below.
