REVASRI Mini7 Laser Ranging Module Instruction Manual

1. Introduction

The REVASRI Mini7 Laser Ranging Module is designed for system integrators to seamlessly incorporate laser ranging capabilities into various systems, including thermal or electro-optical systems, weapon scopes, and consumer products. This module utilizes a 905nm eye-safe laser diode, offering a long operational lifetime and low power consumption.

It provides accurate distance measurements from 10 to 1200 meters with a resolution of 0.1m and a ranging error of ±1m. Its compact size and robust aluminum construction make it suitable for diverse applications.

2. Safety Information

WARNING: Laser Radiation

• This device uses a 905nm Class 1 laser, which is considered safe for human eyes under normal operating conditions. The laser output is less than 5mW.
• Do not stare directly into the laser beam or view it with optical instruments (e.g., binoculars, telescopes) as this may increase eye exposure.
• Do not attempt to disassemble or modify the module. Unauthorized modifications can result in hazardous laser exposure and void the warranty.
• Ensure the module is used in accordance with local regulations and safety standards for laser products.

The testing software and detailed instructions are typically provided via a download link included with your purchase. Follow these steps:

1. Download Software: Access the provided link to download the testing software and any necessary drivers.
2. Install Drivers: Install any required USB-to-serial drivers for the TTL-USB test kit.
3. Install Testing Software: Follow the on-screen instructions to install the REVASRI testing application.

6. Operating Instructions

Once the module is connected and software installed, you can begin operating the Mini7 module.

6.1. Using the Testing Software

1. Launch Software: Open the REVASRI testing software on your computer.
2. Select COM Port: In the software, select the correct COM port corresponding to your connected TTL-USB device.
3. Set Baud Rate: Ensure the baud rate is set to 9600 bps, as specified for the UART communication.
4. Initiate Ranging: Use the software interface to send commands to the module to initiate distance measurements. The software should display the measured distance.

6.2. UART Communication Protocol

For system integrators, the module communicates via a standard UART (TTL 3.3V) interface. The baud rate is 9600 bps. A detailed serial protocol description is typically provided with the testing software and instructions. This document will outline the specific commands and data formats for sending ranging requests and receiving distance data.

Note: The output units for distance measurements are typically in meters. Refer to the detailed protocol documentation for precise unit information and data parsing.

7. Maintenance

The REVASRI Mini7 Laser Ranging Module is designed for durability and requires minimal maintenance.

• Cleaning: Gently wipe the lens part with a soft, clean, lint-free cloth. Avoid abrasive materials or harsh chemicals that could scratch the lens or damage the waterproof seal.
• Storage: Store the module in a dry, cool environment, away from direct sunlight and extreme temperatures.
• Water Resistance: The lens part is waterproof (IP54 rated), offering protection against splashing water. However, the module is not designed for submersion. Ensure connectors are dry before use.
• Battery: If using the test kit, replace the CR2-3V battery when power is low to ensure accurate readings and proper operation.

8. Troubleshooting

If you encounter issues with your REVASRI Mini7 module, refer to the following common problems and solutions:

• No Power/Module Not Responding:
  • Check battery in the TTL-USB test kit. Ensure it is correctly inserted and has sufficient charge.
  • Verify all cable connections between the module, test kit, and computer are secure.
  • Ensure the USB-to-serial drivers are correctly installed on your computer.
• Communication Errors:
  • Confirm the correct COM port is selected in the testing software.
  • Verify the baud rate is set to 9600 bps.
  • Close any other applications that might be using the COM port.
• Inaccurate or No Ranging Data:
  • Ensure the laser path to the target is unobstructed.
  • Check that the target is within the specified ranging scope (10-1200m).
  • Verify the module's lenses are clean and free from dirt or condensation.
  • Confirm the module is receiving stable power.
• Software Issues:
  • Restart the testing software and your computer.
