Huidu HD-R516 LED receiving card with 16 HUB75E outputs
The HD-R516 connects compatible LED sending systems to display modules through 16 onboard HUB75E ports. It supports common and most PWM driver ICs, flexible card ordering and smart screen-layout settings.
Technical specifications
The linked HD-R516 V0.1 document provides the following values. Module-width restrictions apply alongside the recommended loading resolution.
| LED outputs | 16 × HUB75E |
|---|---|
| Recommended loading | 256 × 512 pixels |
| Module width limits | Outdoor ≤256 pixels; indoor ≤128 pixels |
| IC support | Common IC modules and most PWM IC modules |
| Scan / grayscale | Static to 1/64 / 256–65,536 levels |
| Network | 2 interchangeable 1 Gbps Ethernet ports |
| Cable distance | Super Cat5 / Cat6 within 146 m, as stated in V0.1 |
| Power connectors | 2 DC interfaces; either one may be used |
| Supply voltage | 5 V recommended; PDF ranges differ: 4–6 V, 4.5–5.5 V and 4.2–5.5 V |
| Operating temperature | Parameter table −40°C to 85°C; later °C row −40°C to 80°C, incorrectly labelled humidity |
| Storage temperature | −40°C to 105°C |
| Operating humidity | 0–95% |
Revision check: the PDF contains different voltage ranges and two different upper operating-temperature values. Its later −40°C to 80°C row uses °C but is labelled humidity. Confirm these limits for the supplied board before relying on the wider ranges.
Connection and commissioning
Either network port can connect to the sender or a neighbouring receiving card. Match the HUB75E pinout to the LED modules and use the screen routing settings to follow the actual cabinet wiring. The PDF provides connection and interface drawings for setup.
HD-R516 frequently asked questions
How many LED module ports does the HD-R516 have?
The card has 16 onboard HUB75E ports. It also provides two interchangeable Gigabit Ethernet ports for a sending device or another receiving card.
What loading range should I use for R516?
The PDF recommends 256 × 512 pixels and separately limits outdoor module width to 256 pixels and indoor module width to 128 pixels. Check your module size, driver IC and scan configuration before assigning the cabinet load.
Which sending systems are listed for R516?
Listed devices include A4/A5/A6/A601/A602/A603 dual-mode players; A3/A30/A30+/C10/C10C/C30/C15/C15C/C35/C35C asynchronous controllers; T901/T901B/T901S synchronous controllers; and VP210/VP410 video processors.
What power supply does the R516 require?
The specification recommends 5 V. It lists 4–6 V in one table, 4.5–5.5 V at the connectors and 4.2–5.5 V in the technical table. Confirm the supplied revision before applying a voltage outside the recommended 5 V.
How do the status indicators and test button work?
D1 flashes when the card is operating normally. D2 flashes rapidly when Gigabit communication is recognized and data is received. The onboard test button supports checks for screen brightness uniformity and module flatness; an external run/data indicator connection is also provided.
