To ensure correct and safe operation of the product, you must follow generally recognized safety procedures in addition to the safety precautions specified in this manual;

The product is restricted to trained personnel:

Before use, always check that the product is from a known source to ensure correct operation and when integrating this device into a system, the safety of that system is the responsibility of the assembler of the system.

1.2Avoid fire or personal injury

Use the appropriate power cord: Only use the power cord that is dedicated to this product and certified by the country/region where it is located. Do not use other inferior power cords.

Observe all terminal ratings: To avoid fire or electric shock hazards, observe all ratings and markings on the product. Before connecting the product, check the user manual for detailed ratings.

Stay away from exposed circuits: Do not touch exposed connectors and components directly with your hands when the power is turned on.

Do not operate if you suspect a malfunction: If you suspect the product is damaged, have it checked by qualified service personnel. Do not use the product if it is damaged. Do not use the product if it is damaged or malfunctioning. If you suspect a safety issue with the product, turn it off and disconnect the power cord, and clearly mark it to prevent further use.

Do not operate in wet conditions: Please note that condensation may occur if a unit is moved from a cold to a warm location.

Do not operate in flammable or explosive environments: Pay attention to the working environment around the instrument when operating it.

Provide a safe work environment: Make sure your work area meets applicable ergonomic standards.

 1.3 Avoid laser damage to people

Be aware of the harm of laser to human body. Since the laser driven by this product has high output power, please do not look directly at the output port to avoid laser burns to eyes and skin. Do not place the product where children can easily reach it .

1.4 Precautions for use

Reasonable use and careful management of the product can maintain its performance indicators for a long time and extend its service life. Please pay attention to the following matters during use:

The instrument should be protected from mechanical vibration, collision, drop and other mechanical damage.

Please do not disassemble the device by yourself. The product has a self-destruct function. Disassembly by yourself will result in the warranty being void.

Do not allow the device to get wet. Liquids may cause serious damage to the device. Do not use it with wet hands .

Do not use non-special accessories for operation and measurement.

Note:

① To ensure product reliability, voltage fluctuation shall not exceed 10% of the operating voltage range.

② To ensure normal heat dissipation of the laser, please fix it to the relevant heat sink with screws after installing the laser.

Remark:

DC modulation: modulation signal bandwidth: DC-10MHZ

The modulation signal has three levels: Low = 800 µA/V, Medium = 8 mA/V or High = 80 mA/V, corresponding to the L, M, H levels on the board.

Modulation signal voltage range (-1.5V—+1.5V)

3. Configuration instructions and operation steps

Appendix 1 (Status indicator light description)

Appendix 2 (The laser pin sequence is as follows (laser pin example diagram))

Laser Pinout Example

Type B pin

3.1 Configuration instructions:

Power interface: Input +5V DC power supply

Serial port interface: provides relevant communication protocols and host computer

Status indicator light: Indicates the working status of the laser (refer to Appendix 1)

Power: Power indicator light, the light is on, indicating that the power supply is normal

LASER1: Laser control status indicator, on for on, off for off

TEMP1: Laser temperature lock indication, when the thermistor temperature collected differs from the set temperature

When within ±10Ω, the indicator light is on

3.2 Steps:

1. Connect the power supply and check whether the power supply is normal and the Power light is on .

2. Turn off the power and install the laser. Before installation, please carefully confirm the laser pin sequence and direction (refer to Appendix 2) (note that the laser pin definition must be consistent with the appendix) .

Connect the serial port, open the host computer software, and set it according to your needs. For specific operations, please refer to "ONLD Host Computer User Manual".

Note: Please keep the laser close to the heat sink and fix it with screws to ensure normal heat dissipation of the laser.

Note: When the set current exceeds 500mA, please use air cooling or other cooling measures for the module.
