Coin settings for stern spike 2 pinballs

Dimitris Papadakis

Properly adjusting the coin acceptor on a Stern Spike 2 pinball machine is essential for the optimal operation of your machine. In this guide, we will examine two methods of adjustment, emphasizing their advantages and differences.

If we want to adjust the coin acceptor in parallel, then we must take the following into account:

CH5 connector

CN5 Coin Slot Input Pin Comment
Coin 3 / Out 3 Left coin slot pin 9 Used for the base currency 1€
Coin 2 / Out 2 Center coin slot pin 8 Alternative coin insertion 2€
Coin 1 / Out 1 Right coin slot pin 7 Useful for special coins or tokens
Coin Enable/Inhibit (+) ***
pin 6 control mechanism used to enable or disable the coin acceptance function

 

  1. AL55v parallel coin acceptor setup
  2. We define the value of each of our channels.
  3. the machine keeps statistics per channel
  4. We know how many coins were 1€ or 2€ or 0.5€
  5. Greater flexibility in bonus settings

 

  1. Setting only one output on the AL55v coin acceptor
  2. We set a value in only one channel
  3. the machine does not keep statistics per channel
  4. we don't know how many coins were, for example, 1€ and how many were 2€
  5. Compatible with coin acceptors that do not have the ability to program

*** explanation of the enable / inhibit function

  • Enable/Inhibit :

    • Enable : Activates the coin acceptor, allowing it to accept coins.
    • Inhibit : Disables coin acceptance, making the coin acceptor inactive.

  • (+) :

    • The "+" sign means that this function is activated by a positive voltage. To "Enable" the coin acceptor, a positive voltage must be applied to this pin (e.g. 12V or 5V, depending on the coin acceptor).
    • If the pin remains without voltage or receives a negative voltage (GND), then the mode will be "Inhibit" (it will not accept coins)

coin acceptor schematics:

Coin selectors with 10 pole connectors use 6 outputs to indicate coin type that has been detected and accepted. One input called “inhibit” is used to block acceptance of all coins. Some validators have also one output as indication of return or “flight deck” opened. After the acceptance of one programmed coin, corresponding output is activated for a brief time period. Active level is mostly “low” and period is typically 100 ms. For coin selectors AL55/66 user can program time period from 5 to 1000 ms in steps of 5 ms.
