Key Coin Drop Signal Parameters

Pulse Width

- The duration of each pulse signal sent when a coin is detected. Example: If set to 50 ms, each coin generates a 50 ms “high” or “low” signal.

- Too short → controller may miss the pulse.

- Too long → may cause double-counting.

Pulse Delay

- The time gap between consecutive pulses for multi-pulse coins (e.g., a $1 might send 5 pulses,  ).

- Ensures the controller can distinguish between pulses of the same coin vs. pulses from multiple coins.

Coin Signal Sensitive

- Defines how responsive the system is to signal changes.

- Higher sensitivity → detects even small voltage changes (risk of false triggers).

- Lower sensitivity → ignores noise but may miss weak signals.

Coin Signal Idle Level

- The default state of the signal line when no coin is inserted.

- Can be High (logic 1) or Low (logic 0) depending on the coin acceptor design.

- Important so the controller knows what “resting” looks like.

Coin Signal Width

- Similar to pulse width, but sometimes refers to the expected width range the controller accepts as valid.

- Example: Accept pulses between 40–60 ms, reject anything outside that range.

Pulse Pull Down or Up

- Defines whether the signal line is pulled to ground (pull-down) or to Vcc (pull-up) when active.

- Pull-up → idle high, pulse goes low.

- Pull-down → idle low, pulse goes high.

- Must match the coin acceptor’s wiring to avoid inverted signals.

When a coin is inserted:

1. The acceptor sends a series of pulses.

2. Each pulse has a defined width and delay.

3. The controller checks against its sensitivity and idle level settings.

4. The pull-up/pull-down configuration ensures the signal logic matches correctly.

5. The number of pulses corresponds to the coin’s value.

So, LBPayLinker operates emulate to the coindrop pulse setting.
