What Is the Kystar G616 LED Receiving Card?
The Kystar G616 Gold Card receives data from a compatible LED sending controller and converts it into module control signals. Its 16 standard module interfaces provide 32 RGB data groups for full-color LED panels. Use G616 when its connector layout, driver-chip support and configured load match your cabinet or module design.
Functions for LED Panel Setup and Maintenance
- Module data distribution: connect panel ribbon cables through the 16 output interfaces after confirming their signal pinout.
- Brightness and color calibration: apply supported point-by-point brightness and chrominance correction, including low-gray compensation.
- Refresh and grayscale adjustment: configure supported frequency multiplication and low-brightness grayscale functions for the actual panel driver and scan arrangement.
- Configuration readback and recovery: read existing configuration and use supported recovery functions when servicing cards.
- Connection diagnostics: inspect network communication and cable sequence, and configure irregular screen layouts in supported software.
G616 Specifications
| Specification | Details |
|---|---|
| Product role | Full-color LED receiving card; requires a compatible upstream sending controller. |
| Module interfaces | 16 standard 16-pin output interfaces. Confirm ribbon-cable orientation and the documented pin assignment. |
| RGB data groups | 32 groups per receiving card. |
| Network connections | 2 Gigabit network ports. The original specification does not distinguish fixed input and output roles. |
| Supported driver categories | Multiple general-purpose, PWM and dual-latch driver chips. Confirm the exact IC and firmware; this is not a guarantee of support for every chip. |
| Load reference in original Chinese v2.3 | The October 2021 document lists a single-card area of 128 × 1024 and a maximum of approximately 130,000 pixels. Verify the actual load with the panel’s driver IC, scan mode, refresh and card revision. |
| Power reference | Original v2.3 lists 3.5–6 V and 0.6–1.0 A, with 5 V power connections shown. Confirm the supplied board’s connector, polarity and rating. |
| Calibration and maintenance | Point-by-point brightness/chrominance correction, low-gray compensation, configuration readback and recovery. |
Compatibility, Load and Image-Quality Limits
Match G616 to the actual module driver IC, scan ratio, ribbon-cable pinout and color order. The number of interfaces and RGB data groups describes the signal arrangement; it does not alone establish a cabinet resolution or a guaranteed refresh rate. Validate the desired load with the supplied firmware and panel configuration.
The preserved documents describe an older G616 hardware generation, while the manufacturer’s Gx series page lists later G616 documentation. Confirm the board revision before treating a newer specification as applicable to this unit.
Frequency multiplication and calibration can help tune the display, but camera banding also depends on scan mode, LED drivers, refresh settings and camera shutter or exposure. Test the finished display with your camera rather than assuming every setup will be free of scan lines.
For an upstream sending option, review the Kystar S2 two-port sending card and confirm the compatible firmware and total screen mapping.
Frequently Asked Questions
Is G616 a sending card?
No. It receives data from the sending system and provides control signals to LED modules. A suitable sending controller is required upstream.
Does it support every PWM driver chip?
The original document supports multiple PWM driver chips, not universal compatibility. Confirm your exact chip and module configuration before replacing a card.
Can the old card configuration be recovered?
The documented functions include configuration readback and recovery. Keep a known working configuration and confirm the supported procedure for the card and software version.
Summary and Documentation
Choose G616 for compatible LED modules needing its 16-interface, 32-RGB-group arrangement. Verify card revision, load, wiring and driver settings, then test grayscale, calibration and refresh on the completed screen. The original product images and both model PDFs are retained below.
