Coin mechanism
The communication with the coin mechanism is done via a standard parallel interface. There are used 6 signal lines and by transmitted pulses, the passed coins are registered on them.
Exist 4 types of signalization that allow different numbers of recognizable coins.
Singular impulse for each
This is the simplest variant for signalization and in this way, there could be set up to 6 different types of coins.
The setting is done by choosing one active line for each code for a coin. A coin with code 1 - line one, a coin with code 2 - line 2, etc. No line is chosen for the rest of the free codes(7 - 16).
The minimal and maximal duration of the impulse is not significantly important, however, it is necessary to cover the scope set by the coin mechanism. Usually, this duration is either 100 or 200 milliseconds but there are some models with a duration of 500 milliseconds.
The controllers and mints offered by us standard use this variant with the listed nominals:
| Coin code | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| Active line | 1 | 2 | 3 | 4 | 5 | available |
| Nominal | 10 st. | 20 st. | 50 st. | 1 lv. | 2 lv. | available |
A series of impulses
In addition to the previous option, some mints maintain the supply of several impulses on a given line to code the different coins. For instance 1 impulse - 50 st.; 2 impulses - 1 lv.; 4 impulse - 2 lv.
The controller maintains this mode without extra changes in the settings. The condition is the price of the coin should correspond with the number of impulses to the price of a singular impulse.
Impulses with different duration
The controller can determine the duration of the given impulse of the coin mechanism and based on that reads different nominals.
For instance: 100 ms. - 50 st., 200 ms. - 1 lv, 300 ms. - 2 lv.
For the settings it is allowed for several codes for coins to have the same active line but with different minimal and maximal duration for an impulse that does not overlap. For instance: code 1 - 60-140 ms., code 2 - 160-240 ms., code 3 - 260-340 ms.
Combination of active lines (binary)
The coin mechanism can activate several lines simultaneously. In this way, by applying different combinations of active lines there could be recognized up to 16 different types of coins.
For instance, only 1 line - 1 st., 1 and 2 lines - 10 st., 1, 2 and 3 lines - 1 lv.
The setting up of this mode happens by choosing more than 1 active line for the given code. Recognition happens by the exact matching of the active lines.
Допълнителни настройки
Филтриране на смущения - при превключване линиите и при външни шумове е възможно да се регистрират много кратки импулси, които грешно да бъдат разпознати като монети. Този параметър указва импулси с по-малка продължителност от зададената да бъдат пренебрегвани.
Изчакване за край на импулс - възможно е от страна на монетния механизъм някоя линия да бъде поставена в активно състояние. Това е индикация за забрана на този вид монети. За да разпознае контролера това състояние, той изчаква зададеното време, след което спира да следи тази линия.
Забранени линии - Контролера също може да постави някоя линия в активно състояние и така да покаже на монетния механизъм да не приема тези монети. Забележка: не всички монетници разпознават това състояние. То се подържа от G13, но не и от RM5HD.
