GS8512 Pixel Protocol
Manufacturer: Genesis-Systech
The GS8512 is a Genesis-Systech DMX512 LED driver IC in an SOP8 package that decodes a standard DMX512 signal to drive an RGB (3 channel) fixture with 16-bit (65536 level) grayscale at a 12kHz PWM refresh across an 8 to 30V supply.
Specifications

Strengths
- 16-bit (65536 level) grayscale per channel for smooth, high-resolution dimming
- Wide 8 to 30V operating supply with 12V/15V/24V single-lamp and 24V dual-lamp series drive options
- Standard DMX512 input, so it works with any existing DMX512 source or interface without custom protocol timing
Limitations
- RGB only (3 channels), with no dedicated white channel
- Little English-language datasheet presence, as it is a first-party Genesis-Systech (Shenzhen Junlue Technology) part
Overview
The GS8512 is a DMX512 driver IC from Genesis-Systech (Shenzhen Junlue Technology). Rather than acting as a self-clocked pixel chip, it receives a standard DMX512 control signal and decodes it locally to drive an RGB (3 channel) LED load, giving 16-bit (65536 level) per-channel grayscale for smooth dimming and a 12kHz PWM refresh rate. It operates over a wide 8 to 30V supply and supports 12V, 15V and 24V single-lamp drive as well as 24V dual-lamp series drive, making it flexible for a range of fixture voltages. The 12kHz refresh sits comfortably within typical broadcast and cinema frame rates, so on-camera flicker is generally not a concern for standard shooting. Because it is a DMX512 decoder, it is driven by any ENTTEC DMX512 source or interface (for example the DMX USB Pro, ODE or Storm) over a standard DMX line, and does not require a custom pixel-protocol definition. ENTTEC is not affiliated with Genesis-Systech.
