DH7516 LED Receiving Card
General-purpose LED receiver card with 16× HUB75E connectors, up to 32 groups of parallel RGB data, 512×384@60Hz PWM loading, brightness calibration and individual RGB Gamma — supplied by Excelled, a trusted LED screen manufacturer for global B2B system integrators.
Quick Answer: What Is the DH7516 LED Receiving Card?
The NovaStar DH7516 LED receiving card is a general-purpose receiving card designed for LED display cabinets. It loads up to 512×384 pixels at 60Hz over 16 HUB75E connectors with 32 groups of parallel RGB data, supports per-LED brightness calibration and individual RGB Gamma, and is driven by NovaLCT V5.3.0 or later — suitable for rental walls, fixed indoor signage and large-format advertising.
What Is the NovaStar DH7516 LED Receiving Card?
The DH7516 receiver card is NovaStar’s general-purpose receiving card built around 16 standard HUB75E connectors with up to 32 groups of parallel RGB data. With 8bit video sources, a single card loads up to 512×384 pixels at 60Hz using PWM driver ICs, or 384×384 with common driver ICs, when driven by NovaLCT V5.3.0 or later — enough pixels for large cabinets and high-density indoor walls from one card.
What separates the DH7516 from entry-level LED receiver cards is its brightness toolchain: per-LED brightness calibration (working with NovaLCT and NovaCLB) evens out module-to-module brightness drift, quick adjustment of dark or bright lines fixes cabinet splicing seams in seconds, and individual red, green and blue Gamma keeps low-grayscale images uniform and white balance stable.
On the reliability side, the DH7516 carries loop backup over main and backup Ethernet lines, dual application program backup that survives interrupted updates, firmware and configuration readback, Mapping for on-wall card location, and temperature and voltage monitoring without extra hardware. Bit error rate monitoring (NovaLCT V5.2.0+) logs packet errors per port, and RoHS plus EMC Class A certification round out the package.

Why Choose the DH7516 LED Receiving Card: 16-Port Loading, Brightness Calibration & RGB Gamma
Most mid-range LED receiving cards stop at moving pixels. The DH7516 is built to move more of them and keep the image uniform while doing it — that is exactly where its three strengths come from.
DH7516 Features: 16 HUB75E Ports — More Cabinets Per Card
The DH7516’s 16 HUB75E connectors drive up to 32 groups of parallel RGB data — double the data capacity of an 8-port card. Fewer cards per screen means fewer spare parts, simpler wiring and lower per-cabinet cost, which is why integrators pick the DH7516 LED receiving card for mid-size and large walls.
DH7516 Brightness Calibration & Individual RGB Gamma — Uniformity Without the Flagship Price
Panel uniformity is where budget walls fail. The DH7516 answers with per-LED brightness calibration so a replaced module blends into its neighbors, plus individual red, green and blue Gamma that tames color cast at low grayscale. Note the scope: the DH7516 offers brightness calibration only — there is no per-pixel chroma calibration, no 18bit+ processing and no Color Management, so those features are not a reason to choose this card.
How to Install, Wire & Replace the DH7516 LED Receiving Card
The DH7516 mounts directly onto the LED module hub board via its 16 HUB75E connectors. Each 16-pin HUB75E header carries two groups of parallel RGB data (R1/G1/B1 and R2/G2/B2), line decoding signals (HA/HB/HC/HD plus HE), latch (HLAT), output enable (HOE) and shift clock (HDCLK) — the extra E address line enables 1/32 scan support. The card draws power through dual DC input connectors; either can be used.
DH7516 HUB75E Pin Definition (JH1 Reference)
| Pin | Signal | Pin | Signal | Description |
|---|---|---|---|---|
| 1 | R1 (Red data 1) | 2 | G1 (Green data 1) | RGB data group 1 |
| 3 | B1 (Blue data 1) | 4 | GND (Ground) | Ground reference |
| 5 | R2 (Red data 2) | 6 | G2 (Green data 2) | RGB data group 2 |
| 7 | B2 (Blue data 2) | 8 | HE (Line decode E) | E address line — enables 1/32 scan |
| 9 | HA (Line decode A) | 10 | HB (Line decode B) | Row/line addressing signals |
| 11 | HC (Line decode C) | 12 | HD (Line decode D) | Row/line addressing signals |
| 13 | HDCLK (Shift Clock) | 14 | HLAT (Latch) | DCLK shifts data through registers; LAT latches data to output |
| 15 | HOE (Output Enable) | 16 | GND (Ground) | OE controls LED output state |
DH7516 Installation Checklist
- Power off the cabinet before inserting or removing the receiving card — hot-swap is not supported.
- Align pin 1 on both card and hub board — the pin numbering on the connector silkscreen marks orientation.
- Use either DC power input — the DH7516 provides dual power connectors for wiring flexibility.
- Connect Ethernet in loop topology — main and backup lines form a closed loop between sending card and card chain; if one line faults, the screen keeps displaying.
- Verify indicator status — green flashing once every 1s plus red power indicator always on means normal operation with video source present.
- Check the bit error counter in NovaLCT after installation to confirm clean Gigabit links between cards.
How to Configure the DH7516 LED Receiver Card in NovaLCT — Mapping, Firmware & Readback
The DH7516 is configured entirely through NovaLCT (NovaStar LED Configuration Tool for Windows). Full 512×384 loading requires NovaLCT V5.3.0 or later; bit error monitoring, individual Gamma adjustment and firmware readback are available from V5.2.0. Download NovaLCT and NovaCLB from the official NovaStar website — the same tools handle mapping, calibration, firmware and readback across the whole DH series. The card pairs with sending controllers such as the MCTRL660 LED controller, VX1000 all-in-one controller and MCTRL4K controller for complete NovaStar LED control systems — and where a compact mini receiving card fits better, the AT30 LED receiving card covers that category.

DH7516 LED Receiving Card Troubleshooting FAQ — Indicator Codes & Common Fixes
Q1 What is the maximum loading capacity of the DH7516 LED receiving card?
Diagnosis: With 8bit video sources and PWM driver ICs, a single DH7516 loads up to 512×384 pixels at 60Hz; with common driver ICs it loads 384×384 pixels. Solution: Both capacities require NovaLCT V5.3.0 or later. Confirm your driver IC type before specifying the card count — PWM ICs unlock the higher 512×384 loading per card.
Q2 DH7516 vs DH7508 vs MRV416-N — which NovaStar receiving card should I choose?
Diagnosis: The lineup splits by port count and processing depth: the DH7516 offers 16 HUB75E ports with up to 512×384@60Hz loading, the DH7508 covers budget 8-port cabinets, and the MRV416-N adds 512×512 loading plus 18bit+ processing. Solution: Choose the DH7516 for 16-port cabinets that need maximum loading per card at an accessible price — it shares the 145.6×91.5mm footprint with the MRV416 family, so a batch swap onto existing hub boards is straightforward. Verify the connector count and pin-1 orientation of your hub boards first, and re-map the replaced cabinets in NovaLCT after swapping.
Q3 Does the DH7516 support per-pixel chroma calibration?
Diagnosis: No. The DH7516 supports per-LED brightness calibration only, not chroma calibration. Solution: Brightness calibration evens out module-to-module brightness; for color-uniformity projects you need a card with per-pixel chroma calibration such as the MRV416-N or DH7512. Check the calibration requirement in your tender specification before purchasing.
Q4 How do I configure the DH7516 receiving card in NovaLCT?
Diagnosis: Configuration requires NovaLCT V5.3.0 or later on a Windows PC. Solution: Connect the PC to the same network as the sending controller, detect the receiving cards, set up screen mapping, upload brightness calibration coefficients, then verify the bit error counter reads zero before going live. All settings are stored in the card and survive power cycles.
Q5 Why is NovaLCT not detecting my DH7516 receiving card?
Diagnosis: Usually a network-layer issue rather than a card fault. Solution: Confirm NovaLCT V5.3.0 or later, check that the PC is on the same subnet as the controller, and allow the discovery port through the firewall. Check the indicators: green flashing once per second means the card is healthy; other patterns point to cabling or the video source.
Q6 How do I update the firmware on the DH7516 receiving card?
Diagnosis: Firmware is updated and read back through NovaLCT, with readback available from V5.2.0. Solution: Download the latest package from the NovaStar download center, flash one card first, and read the program back to the local computer for archival. Dual application program backup means an interrupted update falls back to the backup copy instead of bricking the card.
Q7 How many DH7516 receiving cards does my LED wall need?
Diagnosis: Divide the wall’s pixel dimensions by the card’s loading capacity in each axis and round up. Solution: Example: a 1920×1080 wall with PWM driver ICs = 4 cards across (1920/512) × 3 cards down (1080/384) = 12 cards. The practical count also depends on cabinet scan rate and HUB layout — share your module size for an exact calculation.
Q8 What power supply does the DH7516 receiving card need?
Diagnosis: DC 3.3V–5.5V input, either of the dual power connectors. Solution: Use the cabinet’s existing 5V rail — rated current is only 0.5A at 2.5W, so the card adds negligible load to the power budget. The red power indicator stays on when input is normal, and NovaLCT reports the card’s measured voltage and temperature.
Q9 What is the DH7516 price for wholesale orders?
Diagnosis: NovaStar publishes no fixed retail price; genuine DH7516 pricing depends on quantity, packing and destination. Solution: Excelled supplies the DH7516 on wholesale B2B terms — request a quotation through our contact page with your quantity and destination for volume pricing on the factory-standard 100-cards-per-box packing, with a per-card antistatic bag and anti-collision foam included.
