AMPrime 2.4G Wireless Module Transmitter & Receiver

1. Product Overview

The AMPrime 2.4G Wireless Module Transmitter & Receiver system is designed to convert a wired car rear view camera into a wireless one. This eliminates the need for long video cables running through the vehicle, simplifying installation for parking assistance and reverse viewing systems.

3. Installation Guide

This wireless module system is designed for easy integration with existing wired car cameras and monitors. The following diagrams illustrate typical connection scenarios.

3.1 Wireless Transmitter Connections

1. Connect the Camera Video Jack (yellow RCA) of the transmitter to the video output of your car camera.
2. Connect the Camera Power Jack (red barrel connector) of the transmitter to the power input of your car camera.
3. Connect the Power Positive (red wire) of the transmitter to a +12V power source. For reverse cameras, this should typically be the reverse light circuit to activate the camera when reversing.
4. Connect the Power Negative (black wire) of the transmitter to a ground point.

3.2 Wireless Receiver Connections

1. Connect the Monitor Video Jack (yellow RCA) of the receiver to the video input of your car monitor or head unit.
2. Connect the Power Positive (red wire) of the receiver to a +12V power source. This can be the same reverse light circuit as the transmitter, or a switched 12V source that activates when the monitor needs to display the camera feed.
3. Connect the Power Negative (black wire) of the receiver to a ground point.

3.3 Overall Installation Diagram

For detailed wiring, ensure both the transmitter and receiver are powered by a +12V source. If used for a reverse camera, connect the transmitter's power to the reverse lamp circuit. The receiver's power can also be connected to the reverse lamp circuit, or to an accessory power source that activates the monitor when needed. If your car radio has a 'BACK' pin, connect it to the reverse lamp circuit to automatically switch to the camera input.

For additional visual guidance, refer to the comprehensive installation diagrams available in the User Manual (PDF).

4. Operation

Once properly installed and powered, the wireless module system operates automatically:

1. When the car camera receives power (e.g., by engaging reverse gear), it sends video to the wireless transmitter.
2. The transmitter converts the video signal into a 2.4G wireless signal and broadcasts it.
3. The wireless receiver, when powered, continuously scans for the signal from the transmitter.
4. Upon receiving the signal, the receiver converts it back into a standard video signal and sends it to the connected monitor/head unit.
5. The monitor/head unit displays the camera feed. If the receiver's power is linked to the reverse light, the display will automatically switch to the camera view when reverse gear is engaged.

5. Maintenance

• Keep the transmitter and receiver units clean and free from dust and moisture.
• Regularly check all cable connections to ensure they are secure and free from corrosion.
• Avoid exposing the units to extreme temperatures or direct sunlight for prolonged periods.
• Do not attempt to open or modify the units, as this may void the warranty and cause damage.

6. Troubleshooting

No Signal / Black Screen:

• Ensure both the transmitter and receiver are receiving power (check wiring to +12V and ground).
• Verify that the camera is powered on and functioning correctly.
• Check all RCA video connections for proper seating and damage.
• Confirm that the monitor/head unit is set to the correct video input channel.

Interference / Flickering Display / Signal Delay:

• Reposition the transmitter and receiver units to minimize obstructions and potential sources of electromagnetic interference (e.g., other wireless devices, large metal objects).
• Ensure the units are not too close to high-power electrical components in the vehicle.
• Check for any loose connections that might cause signal degradation.

Unit Gets Hot:

• While some warmth is normal during operation, excessive heat could indicate an issue. Ensure proper ventilation around the units.
• Verify that the input voltage is within the specified DC 9-14V range.

Does Not Work At All:

• Double-check all wiring against the installation diagrams.
• Test components individually if possible (e.g., test camera with a wired connection).
• Ensure the power source provides stable 12V.

7. User Tips

• Optimal Positioning: For best performance and to avoid interference, carefully consider the placement of both the transmitter and receiver units. Try to minimize physical obstructions between them.
• Reverse Light Connection: When using for a reverse camera, connecting the car radio's 'BACK' pin to the dedicated reverse fuse in the front compartment can ensure reliable automatic switching to the camera view.
• Power Supply: Ensure both the transmitter and receiver are connected to a stable +12V power source. For automatic activation, the transmitter should be wired to the reverse lamp circuit.
• Heat Management: Some users have noted the units can get warm. Ensure they are installed in a location with adequate ventilation to prevent overheating.

8. Frequently Asked Questions (FAQ)

Q: Can I use two of these wireless systems in one car?

A: The product description does not specify multi-channel support. Using two 2.4G wireless systems simultaneously in the same vehicle may lead to signal interference between the units, potentially causing unreliable video transmission. It is generally not recommended unless the product explicitly states multi-channel capability.

Q: Is there a 5-volt version of this module?

A: No, this specific model is designed for a DC 9-14V input. Using a 5-volt power supply will not provide sufficient power for operation.

Q: Does this wireless connection work with all common plug-compatible reversing cameras?

A: Yes, this module uses standard RCA connectors for video input/output, making it compatible with most aftermarket car cameras and monitors that also use RCA connections.
