1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of the BouPower 13398-DO Dual Synchronous Velocity Slide Controller. This controller is designed to manage the slide-out systems in recreational vehicles (RVs), ensuring smooth and synchronized movement. Please read this manual thoroughly before installation and use to ensure proper function and safety.
2. Safety Information
- Always disconnect the RV's battery power before performing any electrical work or installation.
- Ensure all connections are secure and properly insulated to prevent short circuits.
- Do not tamper with the internal components of the controller. This is not a user-serviceable device, and tampering will void the warranty.
- Verify correct voltage (12V DC) before connecting the controller.
- Keep the controller away from moisture and extreme temperatures.
3. Product Overview
The BouPower 13398-DO is an advanced dual synchronous velocity slide controller. It is a direct replacement for the V-Sync II controller and is specifically designed for Lippert In-Wall Slide-Out systems on RVs. This unit ensures precise and balanced movement of your RV's slide-out room during extension and retraction.

5. Operating Instructions
5.1 Mode Button (Manual Override)
The mode button is used to engage the electronic manual override function. This can be useful in situations where the standard slide control is not functioning.
- To Manually Override:
- Press the button 6 times and hold down on the 7th press until the lights start to flash.
- Use the normal slide control switch located inside the coach to retract the room.
5.2 Status LEDs (Fault Indication)
The controller is equipped with two LEDs (one green, one red) to indicate its current status and any detected faults. These LEDs provide crucial diagnostic information.

Green LED Indications:
- 1 Blink: Motor 1 activity.
- 2 Blinks: Motor 2 activity.
Red LED Fault Indications:
| Blinks | Fault | Description |
|---|---|---|
| 2 | Battery Dropout | Battery capacity drops below 6 volts during operation or there is a short in the switch wiring. |
| 3 | Low Battery | Voltage is below 8 volts at the start of the cycle. |
| 4 | High Battery | Voltage is above 18 volts. |
| 5 | Excessive Motor Current | High current draw, also indicated by one side of the sliding mechanism continually stalling. |
| 6 | Motor Short Circuit | The motor or the wire connected to the motor has short-circuited. |
| 8 | Wire Short Between Controller and Motor | The encoder is not providing a signal. This is usually a wiring issue. |
| 9 | Hall Power Short To Ground | The power supply to the encoder has shorted to ground. This is usually a wiring issue. |
6. Maintenance
The BouPower 13398-DO controller is designed for minimal maintenance. However, regular checks can help ensure its longevity and reliable operation:
- Inspect Connections: Periodically check all wiring connections to ensure they are tight and free from corrosion.
- Keep Clean and Dry: Ensure the controller is kept clean and dry. Avoid exposure to excessive dust, dirt, or moisture.
- Environmental Protection: Protect the controller from extreme temperatures and direct sunlight, which can degrade electronic components over time.
7. Troubleshooting
If you experience issues with your slide-out system, refer to the Red LED Fault Indications table in Section 5.2. The number of blinks from the red LED corresponds to a specific fault code, helping you diagnose the problem.
- No Power: Check battery connections and voltage. Ensure the power connection to the controller is secure.
- Slide-out Not Moving: Check for Red LED fault codes. Verify motor connections and ensure the switch is functioning correctly.
- Uneven Slide Movement: This could indicate an issue with one of the motors or their encoder signals. Check for relevant fault codes (e.g., Excessive Motor Current, Wire Short Between Controller and Motor).
- Manual Override Not Working: Ensure you are following the correct procedure for engaging the manual override (press 6 times, hold on 7th).
If the problem persists after following these steps, contact customer support.
