KYStar G612 Gold Card receiving card
The KYStar G612 converts incoming sending-card data into LED module control signals. The linked specification identifies twelve standard module interfaces and 24 groups of RGB data for a compatible full-color LED display system.
Correction and configuration
Point-by-point brightness and chromaticity correction includes low-gray compensation. The card supports general-purpose, PWM and dual-latch driver chips, along with low-brightness grayscale display and color reproduction adjustment.
Configuration readback, one-click repair, network-status monitoring and cable-sequence detection help with installation and service. Flexible pixel placement supports special-shaped screens, and program write protection is listed in the specification.

Document notes: The pixel-area row’s 128 × 768 value is not numerically identical to its printed maximum of 98,000 pixels; confirm the permitted load for the exact revision and module setup. The feature list describes twelve interfaces, while the port-section heading contains inconsistent “sixteen 8P” and JH1–JH8 wording despite showing pin numbers 1–16. Verify the physical connector layout and matching pinout before wiring.
Replacement planning
Match the full model, revision, module driver, scan settings and supply connections. Keep the current configuration and calibration data where available. G612 specifications should not automatically be applied to G612E or other suffix variants.
Frequently asked questions
How many RGB data groups does G612 provide?
The linked specification lists 24 RGB data groups and twelve standard module interfaces in its feature section. Check its connector note before wiring.
What is the maximum G612 pixel load?
The retained PDF prints 128 × 768 and “MAX 98,000” in the same row. Confirm the applicable load for the exact card revision and module configuration instead of treating those figures as interchangeable.
Can G612 replace G612E directly?
The available G612 document does not establish direct interchangeability with G612E. Match the exact model suffix, pinout, driver-chip configuration and supply requirement.
What functions help recover a screen after card replacement?
The documented functions include configuration readback and one-click repair. Retain the existing settings and check compatibility before replacing the card.
