4. Product Overview

The wonsung LK-20 system comprises several key components that work together to create laser projections. The core of the system is the galvanometer scanner, which uses two small mirrors mounted on motors to rapidly deflect a laser beam in X and Y axes, creating patterns. The main control board (show card) generates the signals that drive these galvanometers, and a power supply provides the necessary electrical current.

The system is modular, allowing for flexibility in integration with existing laser setups or for custom projects.

5. Setup Instructions

Careful assembly and wiring are essential for the correct operation of the LK-20 system. Ensure the power supply is disconnected from the mains during assembly.

5.1 Component Identification

Familiarize yourself with each component. The galvanometer scanners are typically black cylindrical units with small mirrors. The main control board is a circuit board with various connectors and often a digital display or DIP switches. The power supply is a metal enclosure with input and output terminals.

5.2 Wiring Connections

1. Galvanometer to Driver Boards: Connect the X and Y galvanometer scanners to their respective driver board outputs. These connections are typically keyed to prevent incorrect insertion.
2. Driver Boards to Main Control Board: Connect the driver boards to the main control board (show card) using the provided ribbon cables or multi-pin connectors. Ensure correct orientation.
3. Power Supply to Control Boards: Connect the DC output of the power supply to the main control board and driver boards. The system requires a 15V DC power input. Verify polarity before connecting.
4. AC Power Input: Connect the AC input of the power supply to a suitable mains power source. For soldering to an inlet, follow standard IEC AC power wire coloring: brown for the hot line (phase), blue for the neutral line, and yellow/green for grounding. The power supply unit's AC input is typically fused.
5. External Control Connections (Optional): If using external control, connect the DB25 or ILDA connector to the main control board.

After all connections are made, double-check them for security and correct polarity before applying power.

6. Operating Instructions

The wonsung LK-20 offers both standalone operation via its show card and external control options.

6.1 Standalone Operation (Show Card)

The main control board features DIP switches to select various pre-programmed patterns and modes. Refer to the specific DIP switch settings provided with your show card for detailed mode selection. For a quick test, setting all switches to LOW except for switch 1 and switch 10 (resulting in a [1000000001] configuration) will activate an 'auto cartoon' mode, displaying random animations.

Some show cards also include a microphone input, allowing the system to generate patterns influenced by ambient audio signals.

6.2 External Control (ILDA/DMX)

The system supports external control via ILDA (International Laser Display Association) and DMX512 interfaces. This allows for advanced control from a computer or dedicated lighting console.

• ILDA: Connect an ILDA-compatible Digital-to-Analog Converter (DAC) to the DB25 port on the main control board. Software like Pangolin's BEYOND can then be used to create and project complex laser shows.
• DMX512: A 3-pin connector is available for DMX interface. An XLR/DMX connector with appropriate wiring is needed to connect the PCB port to a DMX adapter. Software such as freeStyler can be used for DMX control.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your laser galvo system.

• Cleaning Mirrors: Periodically inspect the galvanometer mirrors for dust or smudges. Use a soft, lint-free cloth and a specialized optical cleaning solution to gently clean the mirror surfaces. Avoid touching the mirrors with bare hands.
• Connection Checks: Ensure all wiring connections remain secure. Loose connections can lead to intermittent operation or component damage.
• Environmental Conditions: Operate the system in a clean, dry environment. Avoid excessive dust, humidity, and extreme temperatures.
