Huidu HD-R612 receiving card for LED screen modules
The HD-R612 has 12 onboard HUB75E outputs and two interchangeable Gigabit Ethernet ports. The linked specification identifies LS9929 / LS9919 driver-chip modules as its dedicated application, while also describing conventional receiving-card use.
Technical parameters
Values below are from HD-R612 specification V0.1. Conflicting supply and temperature entries are kept visible for configuration checks.
| Module interfaces | 12 × HUB75E |
|---|---|
| Primary application | Modules using LS9929 / LS9919 driver chips; also usable as a conventional receiving card |
| Recommended load | 256 × 256 pixels; outdoor module width ≤256, indoor module width ≤128 |
| Conventional-card limit | 128 × 1024, stated in the PDF overview; verify the module configuration |
| Scan / grayscale | Static to 1/64 scan / 256–65,536 levels |
| Network | 2 interchangeable Gigabit Ethernet ports |
| Cable distance | Super Cat5 / Cat6 within 146 m, as stated in V0.1 |
| Power connections | 2 DC power interfaces; either one may be used |
| Supply voltage | 5 V recommended; document ranges differ—see note below |
| Operating temperature | Parameter table: −40°C to 85°C; later °C row: −40°C to 80°C, with incorrect humidity label |
| Storage temperature | −40°C to 105°C |
| Operating humidity | 0–95% |
Power and temperature note: the PDF recommends 5 V but gives three different voltage ranges: 4–6 V, 4.5–5.5 V and 4.2–5.5 V. Its working-temperature table lists −40°C to 85°C, while a later row marked in °C lists −40°C to 80°C and is incorrectly labelled as humidity. Confirm the applicable limits for the supplied revision.
Wiring and commissioning
Connect the sending system or another receiving card through either network port. Use the HUB75E pin definitions in the PDF to match the LED modules. Smart settings support screen layout, and receiving cards may be arranged in any sequence. D1 flashing indicates normal operation; rapid D2 flashing indicates Gigabit recognition and data reception.
HD-R612 frequently asked questions
What LED modules is HD-R612 designed for?
The V0.1 specification describes it as a dedicated receiving card for LS9929 / LS9919 chip modules. It also lists support for common IC modules and most PWM IC modules; confirm the actual driver IC and module wiring.
What is the R612 recommended loading range?
The parameter table recommends 256 × 256 pixels, with outdoor module width no more than 256 and indoor module width no more than 128. The overview separately states a 128 × 1024 conventional-card limit. These statements should be checked against the actual module configuration, not combined into an unrestricted load.
Which sending devices are listed as compatible?
The PDF lists A4, A5, A6, A601, A602 and A603 players; A3, A30, A30+, C10, C10C, C30, C15, C15C, C35 and C35C asynchronous controllers; T901, T901B and T901S synchronous controllers; and VP210 / VP410 processors.
What voltage should I use for the HD-R612?
The document recommends a standard 5 V supply. Its ranges differ: 4–6 V in the parameter table, 4.5–5.5 V at the connector descriptions and 4.2–5.5 V in the technical table. Confirm the supplied board limits before using a voltage other than the recommended 5 V.
Can I check the card without sending normal program content?
The onboard test button is described as providing screen tests for brightness uniformity and module flatness. The card also has power/data status indicators and an external indicator connection.
