The 5-wire harness is color-coded for easy identification and connection. Below is the pinout configuration:

1. Connect the Harness to the Pump:
   Attach the JST XH 5-pin connector to the corresponding port on the Kamoer peristaltic pump. Ensure the connector is securely seated.

2. Wire the Harness to a Controller:

   • Connect the Red (VCC) wire to a 12V DC power supply.
   • Connect the Black (GND) wire to the ground of the power supply and controller.
   • Connect the Yellow (DIR) wire to a digital output pin on your microcontroller to control the pump's direction.
   • Connect the Green (PUL) wire to a PWM-capable digital output pin to control the pump's speed.
   • Connect the Blue (EN) wire to a digital output pin to enable or disable the pump.

3. Program the Controller:
   Use a microcontroller (e.g., Arduino UNO) to send control signals to the pump. Below is an example Arduino sketch:

// Define pin connections for the Kamoer 5-wire harness
const int dirPin = 2;  // Direction control pin
const int pulPin = 3;  // Pulse signal pin
const int enPin = 4;   // Enable signal pin

void setup() {
  // Set pin modes
  pinMode(dirPin, OUTPUT);
  pinMode(pulPin, OUTPUT);
  pinMode(enPin, OUTPUT);

  // Initialize pump in disabled state
  digitalWrite(enPin, LOW);  // Disable pump
  digitalWrite(dirPin, LOW); // Set initial direction
}

void loop() {
  // Enable the pump
  digitalWrite(enPin, HIGH);

  // Set pump direction to clockwise
  digitalWrite(dirPin, LOW);

  // Generate pulse signals to control pump speed
  for (int i = 0; i < 1000; i++) {
    digitalWrite(pulPin, HIGH);
    delayMicroseconds(500); // Adjust delay for speed control
    digitalWrite(pulPin, LOW);
    delayMicroseconds(500);
  }

  // Disable the pump after operation
  digitalWrite(enPin, LOW);

  // Wait before the next operation
  delay(2000);
}

• Power Supply: Ensure the power supply provides a stable 12V DC output with sufficient current capacity (at least 2A).
• Signal Integrity: Use short, shielded wires for signal connections to minimize noise and interference.
• Direction Control: Toggle the DIR pin to change the pump's direction. Ensure the pump is stopped before changing direction to avoid damage.
• Enable Signal: Use the EN pin to disable the pump when not in use, reducing power consumption and wear.
• Heat Management: Avoid prolonged operation at maximum speed to prevent overheating.

1. Can I use a different voltage supply?
   No, the harness and pump are designed for 12V DC operation. Using a different voltage may damage the pump.

2. What happens if I leave the EN pin floating?
   The pump may behave unpredictably. Always set the EN pin to HIGH or LOW explicitly.

3. Can I extend the wire length?
   Yes, but ensure the extended wires are of the same gauge (24 AWG) and use shielded cables to minimize signal degradation.

4. Is the harness compatible with other pumps?
   This harness is specifically designed for Kamoer peristaltic pumps. Compatibility with other pumps is not guaranteed.
