5. Operating Instructions
The BETOPPER LC003-HB offers versatile control options:
5.1. Standalone Operation
Use the control panel on the rear of the fixture to select modes and adjust settings. The display and buttons (Menu, Up, Down, Enter) allow for direct control over functions such as color temperature and dimming.
5.2. DMX-512 Control
Connect the fixture to a DMX controller using standard 3-pin XLR cables. Set the DMX address on the fixture via the control panel. Refer to your DMX controller's manual for specific programming instructions. This allows for integration with other stage lighting equipment.
5.3. Master-Slave Mode
To synchronize multiple LC003-HB units, connect them in a daisy-chain configuration using DMX cables. Designate one unit as the "Master" and the others as "Slaves" through their respective control panels. The slave units will then mimic the master unit's settings and effects.
5.4. Color Temperature Adjustment
The fixture provides pure white (5600K) and off-white (3200K) light beams. Adjust the color temperature via the control panel or DMX to suit your specific lighting needs.
