Huidu HD-R3210 receiving card with 10 HUB320F interfaces
The Huidu HD-R3210 is an LED receiving card for synchronous and asynchronous display control systems. Ten onboard HUB320F interfaces support 40 groups of parallel RGB data or 120 groups of serial data. Select it by the module interface, driver IC, scan method and cabinet resolution.
The reference below follows Huidu HD-R3210 Product Specifications V1.0, released October 15, 2025. Confirm the installed board revision and firmware before replacement. The usable pixel load depends on the number of interfaces used and the module resolution.
HD-R3210 module and loading specifications
| Module interfaces | 10 standard onboard HUB320F interfaces |
|---|---|
| Data output | 40 parallel RGB groups or 120 serial data groups |
| Maximum load in parameter table | 512 × 512 pixels at 60 Hz; actual load depends on module resolution and interfaces used |
| Module examples in specification | P1.25 modules × 8; ≥ P1.5 modules × 10 |
| Supported driver IC modules | Common IC modules and most PWM IC modules; verify the specific IC and configuration |
| Scan range | Static to 1/128 scan, subject to the decoder restriction below |
| Sending-device types | Dual-mode sending box, asynchronous sending card, synchronous sending card and Huidu VP-series video processor |
| Grayscale | 256–65,536 levels |
Decoder restriction: V1.0 states that 138-series decoding does not support 1/8 scan or above, listing 138, 5166, 5266, 2012, 2013, 7258 and 32019. Confirm the module decoder and scan ratio before selection; the overall scan range alone does not establish compatibility.
Power, installation and communication
| Operating voltage | DC 3.8–5.5 V |
|---|---|
| Listed power consumption | 3 W |
| Board footprint in drawing | 144.0 × 91.5 mm |
| Net weight | About 97 g |
| Operating temperature / humidity | −25°C to +75°C / 0–95% RH |
| Communication | Gigabit Ethernet |
| Specified cable distance | Within 80 m using Super Cat5 or Cat6 network cable |
| Image rotation | 0°, 90°, 180° and 270° |
Compare mounting positions, power polarity and cable access with the existing cabinet. Switch off power before replacing or wiring the card, as directed in the manual. The specification includes the connection diagram and the JH1 interface definition.
Configuration, image correction and maintenance
Smart settings and screen-layout configuration support module arrangements. The built-in screen test helps check brightness uniformity and module flatness. Point-by-point brightness and color correction works with a grayscale correction system; RGB gamma, light/dark-line and seam adjustments provide additional image tuning.
Modules equipped with Flash can store and read back correction coefficients. A pre-saved screen can display at startup, after a network disconnection or when no video-source signal is present. The card monitors its own temperature and voltage without external equipment and records runtime.
Configuration parameters can be saved to a factory area and restored after changes. The card also stores two firmware programs to help recover from an abnormal update. Keep the working receiver configuration and correction files before maintenance.
Huidu HD-R3210 FAQ
Why does the manual mention both 260,000 pixels and 512 × 512?
The overview states up to 260,000 pixels, while the parameter table lists 512 × 512 at 60 Hz. These are the supplied document’s figures. Confirm the usable cabinet load from the actual module resolution and interface arrangement rather than treating either as an unconditional system capacity.
Does support for most PWM IC modules cover every scan configuration?
No. Check the actual driver IC, decoder and scan ratio, including the 138-series restriction above. Provide the module model and configuration for a compatibility check.
Is HD-R3210 a standalone media player?
It is a receiving card used with a compatible sending device. The specification lists synchronous, asynchronous and dual-mode sending types plus Huidu VP-series video processors.
