How The Validator Works - Azkoyen COMBO-T Technical Information

• It has an effective "anti-fishing system" which has the job of foiling any attempt of fraud using the
procedure of tying a string to a coin.
• Modular construction.
• It can control 3 and 5-way sorters.
• Built with plastic material of the latest generation, wear-resistant, dissipating of static electricity, of high
rigidity and dimensionally stable at high temperatures and humidity (low level of absorption) and
resistant to saline mist.
• The lifespan is guaranteed for more than 1.000.000 services.
• It has a hardware test (perform self-check), that is requested by the machine, which informs it of any
possible anomalies that are occurring inside the validator.

5.1.2 How the validator works

The validator works as a peripheral inside the Combo T and the whole system, through the cctalk bus. It is
the system that has full control of the validator. Each time that the system is activated or a reset is
performed, the validator remains with all coins inhibited and classifies in only one direction.
Once the system to which it belongs begins communication with the validator, it informs the validator of the
coins that can be admitted and the classification that has to perform, these programmes are stored in the
RAM of the validator and can be modified in any time, but only from the machine itself.
Communication of the machine with the validator is permanent (credit polling), recording any credit or error
that could have been generated by the validator. If communication stops during 1 second or more, the
validator would stop accepting coins.
Once a coin has been inserted, it is analysed by the sensor module and if it corresponds to a programmed
coin that is not inhibited, it is automatically accepted and the machine is informed.
For more information about the different commands of operation, check the module Protocol cctalk of this
product.
