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.
