HD-C36C LED Control CardAsynchronous Cascade Card — 524,288 Pixels, 10 Onboard HUB75E, Wi-Fi APP & Remote Power Relay
Huidu HD-C36C asynchronous LED control card for mid-size full-color screens: 1024×512 pixel control, 10 onboard HUB75E outputs, 4GB storage with U-disk expansion, and phone APP control over Wi-Fi — supplied by Excelled, a trusted LED screen manufacturer for global B2B buyers.
What Is the Huidu HD-C36C LED Control Card?
The HD-C36C LED control card is the bigger brother of the HD-C16C: an asynchronous cascade card that integrates sending and receiving functions on one PCB. Its control range of 524,288 pixels (1024×512) covers the mid-size walls the C16C cannot, while keeping the same 10 onboard HUB75E connectors for direct module driving.
Content updates run over network cable, Wi-Fi (phone APP “Screen Master”), or U-disk. A relay output provides remote power control, and the card supports temperature, humidity and brightness sensors for environmental overlays on the screen.
• Control range: 524,288 pixels (1024×512); widest 8192 px, highest 1024 px.
• Storage: 4GB onboard flash, expandable via U-disk.
• Onboard display output: 10× HUB75E connectors — works as a receiving card.
• Output: 1× 1Gbps RJ45 (to HD-R receiving cards) + dual-track stereo audio.
• Inputs: 1× 100Mbps RJ45, USB 2.0, test button, sensor port, GPS port.
• Remote power: 1× relay control interface.
• Power: 8W at 5V DC. Operating temperature: -40°C to +80°C.

Why the HD-C36C Is the Sweet Spot for Mid-Size Asynchronous Walls
1024×512 on One Card
The 524,288-pixel budget covers the wall sizes where the HD-C16C stops — storefront video walls and mid-size indoor displays — without stepping up to a player box with a separate power budget.
Direct Module Driving
Ten onboard HUB75E connectors mean a screen up to the card’s range needs no separate receiving card. Fewer components per install: fewer power supplies, fewer cables, fewer failure points.
Expand With HD-R Receiving Cards
The gigabit output cascades HD-R series receiving cards for larger configurations within the 524,288-pixel budget — the same ecosystem as the C16C, so spare parts and config files interchange.
HD-C36C Pixel Capacity Calculator: Will Your Wall Fit?
The 524,288-pixel budget and the 1024-pixel height limit are the two numbers to check before quoting.
Example 2 — Does not fit: a 1280×1024 pixel wall = 1,310,720 px — over budget. Result: move up to the HD-A5 player box or split across two cards.
Example 3 — Height trap: 8192×1024 px passes the height limit but the pixel total (8.4M) far exceeds budget — pixel total and dimension limits must both pass.
General rule: pixel total ≤ 524,288, height ≤ 1024 px, width ≤ 8192 px. Send us your module count and pixel pitch for a free load check with your cabinet files.
When Should You NOT Choose the HD-C36C?
• Your screen needs more than 524,288 pixels — use the HD-A5 player box or split the wall.
• You need live HDMI input — the C36C is asynchronous only; choose the HD-A5 or HD-A6L.
• Your screen is smaller than 122,880 pixels — the HD-C16C costs less.
• You run single/dual-color text signs — the Huidu W-series sign cards are the right tool.
Right-sizing the card keeps project cost and complexity in line — the C36C wins in the 122,880-to-524,288-pixel band.
Huidu Card Selection Tree
How to Wire the HD-C36C Control Card
Three connections put the screen on air; everything else is program management over network, Wi-Fi or U-disk.
- Power: 5V DC into either the screw terminal or the fool-proof power connector.
- Modules: Ribbon cables from the 10 HUB75E headers to the LED modules — keyed orientation on each cable.
- Network: Input RJ45 to the PC for debugging and publishing; output RJ45 to the first HD-R receiving card when cascading.
- Options: Wi-Fi antenna for APP control, 4G module (not standard), relay to the power supply, temperature/humidity/brightness sensors.
HD-C36C Setup with HDPlayer — Step by Step
The C36C is configured with HDPlayer on PC, then updated day-to-day from the phone APP (“Screen Master”) or the Huidu cloud platform.
- Step 1 — Install HDPlayer and connect the PC to the input network port.
- Step 2 — Auto-detect: the card is recognized automatically — no complicated network setup, plug and play.
- Step 3 — Configure the screen: module type, scan mode (static to 1/64), resolution up to 1024×512.
- Step 4 — Edit the program: video, pictures, GIF, Office documents, clocks and timing pages.
- Step 5 — Publish: over network, Wi-Fi, or U-disk.
- Step 6 — Test: press the test button for aging test lines on the display.
- Step 7 — Schedule power: configure the relay for timed power on/off.
- Step 8 — Backup: save the configuration for field replacement.

HD-C36C Common Issues & Diagnostic Procedures
Straight answers from our support engineers’ most frequent HD-C36C LED control card tickets.
Q1 How many pixels can the HD-C36C control?
524,288 pixels (1024×512), with a maximum width of 8192 pixels and maximum height of 1024 pixels, through onboard HUB75E connectors or cascaded receiving cards.
Q2 Can the HD-C36C work without a receiving card?
Yes. The ten onboard HUB75E interfaces act as a receiving card, so one card drives a screen up to its pixel budget directly.
Q3 How do I update content without internet?
Copy the program to a USB flash drive and insert it into the USB 2.0 port, or connect over the network cable or Wi-Fi for one-to-one updates.
Q4 What software controls the HD-C36C?
HDPlayer on PC for configuration and program editing, the Screen Master phone APP for wireless updates, and the Huidu cloud platform for Internet cluster management.
Q5 What is the relay interface for?
The relay output controls the screen’s power supply remotely – typically used to schedule the screen on during business hours and off overnight.
Q6 Why does my card lose the clock time after power-off?
The on-board battery keeps time storage. If time resets, the battery is loose or drained – reseat or replace it.
