MRV416 LED Receiving Card
Flagship general-purpose LED receiver card with 16× HUB75E enhanced connectors, 512×512@60Hz pixel loading, 18bit+ grayscale, Color Management, and 1-frame Low Latency — supplied by Excelled, a trusted LED screen manufacturer for global B2B system integrators.
Quick Answer: What Is the MRV416 LED Receiving Card?
The NovaStar MRV416 LED receiving card is a general-purpose receiver card in NovaStar’s MRV series, built for LED display walls. The MRV416 features 16 HUB75E connectors and loads up to 512×512@60Hz with 18bit+ grayscale, Color Management and 1-frame Low Latency for broadcast-grade images, configured via NovaLCT V5.3.0+ — a fit for indoor walls, live events and broadcast applications.
What Is the NovaStar MRV416-N LED Receiving Card?
MRV416 LED receiving card (current revision MRV416-N) is NovaStar’s general-purpose receiving card built on 16 standard HUB75E connectors, supporting up to 32 groups of parallel RGB data. With 8bit video sources, a single card loads up to 512×512 pixels at 60Hz with PWM driver ICs, or 512×384@60Hz with common driver ICs — enough for a 6.5sqm P2.5 indoor wall from one card, or half that for high-scan fine-pitch modules.
What separates the MRV416-N from ordinary LED receiver cards is its display-quality toolchain: 18bit+ grayscale processing (4× the standard 16bit level, killing grayscale banding at low brightness), Color Management across Rec.709 / DCI-P3 / Rec.2020 gamuts, pixel-level brightness and chroma calibration, and a Low Latency mode that cuts end-to-end delay to 1 frame — a combination you only find on NovaStar’s flagship receiving cards. On the reliability side, it carries loop backup over dual Gigabit Ethernet, dual program backup, and dual configuration parameter backup, plus RoHS and EMC Class A certification.
Maintenance is where the MRV416-N saves field hours: Mapping 1.1 shows controller/card numbers and Ethernet topology on the cabinets, temperature and voltage are monitored without extra hardware, bit errors and Ethernet cable disconnections are logged, and both firmware and configuration parameters can be read back for offline archival via NovaLCT.
Pixel Capacity
Max 512×512@60Hz per card with PWM driver ICs via 16× HUB75E and 32 groups of parallel RGB data.
4× Grayscale

Why Choose the MRV416-N: 18bit+ Color Management & 1-Frame Low Latency Explained
Most mid-range LED receiving cards pass pixels through untouched. The MRV416 receiver card processes them — and that processing is exactly what separates a washed-out wall from a broadcast-grade one. Two features do the heavy lifting:
MRV416 18bit+ Processing — Why Your Dark Scenes Look Better
When an LED screen dims to 10% brightness, a standard card may only use a fraction of its 16bit grayscale range, so gradients like sunsets or stage smoke break into visible bands. 18bit+ multiplies the grayscale levels by 4 and remaps them across the whole brightness range — the image stays smooth from 100% down to near-black. In practice: no banding on dark scenes, no color cast at low brightness, and a visibly smoother image on fine-pitch indoor walls.
MRV416 Low Latency — 1 Frame From Source to Screen
Standard receiving-card chains add 2–3 frames of delay. For a live camera feed on stage, that lag shows up as lip-sync drift on the wall. The MRV416-N’s Low Latency mode reduces the delay on the receiving-card end to 1 frame (with driver ICs that have built-in RAM), and it can be enabled or disabled per project — off for static signage, on for live events, broadcast studios and interactive floors.
How to Install, Wire & Replace the MRV416-N LED Receiving Card
The MRV416-N mounts onto the LED module hub board inside the LED cabinet via its 16 HUB75E connectors. Each 16-pin HUB75E header carries 2 groups of parallel RGB data (R1/G1/B1 and R2/G2/B2), five line decoding signals (HA/HB/HC/HD/HE), latch (HLAT), output enable (HOE), and shift clock (HDCLK) — the extra E address line enables 1/32 scan support. The card is powered through dual DC input connectors; either can be used.
MRV416 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 | HE1 (Line decode E) | E address line — enables 1/32 scan |
| 9 | HA1 (Line decode A) | 10 | HB1 (Line decode B) | Row/line addressing signals |
| 11 | HC1 (Line decode C) | 12 | HD1 (Line decode D) | Row/line addressing signals |
| 13 | HDCLK1 (Shift Clock) | 14 | HLAT1 (Latch) | DCLK shifts data through registers; LAT latches data to output |
| 15 | HOE1 (Output Enable) | 16 | GND (Ground) | OE controls LED output state |
MRV416 Installation Checklist
- Power off the cabinet before inserting or removing the receiving card — hot-swap is not supported.
- Align HUB75E pin 1 on both card and hub board — pin 1 is marked with a triangle/notch on the connector silkscreen.
- Use either DC power input — the MRV416-N has dual power connectors for wiring flexibility.
- Connect Ethernet in loop topology — main and backup lines form a closed loop between sending card and receiving card chain; if one line faults, the screen keeps displaying.
- Press self-test button twice after Ethernet disconnect to display test patterns — press again to cycle through patterns. Useful for pre-source cabling checks.
- Verify indicator status — green flashing once every 1s = normal with video source; red always on = power OK.

MRV416-N Troubleshooting FAQ — Indicator Codes & Common Fixes
Q1 What is the MRV416 LED receiving card and what does it do?
Diagnosis: The MRV416 is NovaStar’s general-purpose LED receiving card, current revision MRV416-N. Solution: It sits between the sending controller and the LED modules, loading up to 512×512 pixels at 60Hz through 16 HUB75E connectors with 32 groups of parallel RGB data, while 18bit+ grayscale, Color Management and a 1-frame Low Latency mode drive the display — all configured in NovaLCT V5.3.0 or later.
Q2 What is the MRV416 price for wholesale orders?
Diagnosis: NovaStar publishes no fixed retail price; genuine MRV416 pricing depends on quantity, packing and destination. Solution: Excelled supplies the MRV416 on wholesale B2B terms. Request a quotation through our contact page with your quantity and destination, and you will receive volume pricing for the factory-standard blister pack — 100 cards per box.
Q3 Where can I find the MRV416 manual, datasheet and firmware?
Diagnosis: The official reference document is the MRV416-N Receiving Card Specifications V1.0.3; firmware and NovaLCT are distributed through NovaStar’s official channels. Solution: Read the V1.0.3 document for maximum resolution, pin definitions, indicator codes and environmental limits. Update firmware only through NovaLCT V5.3.0 or later — dual program backup makes an interrupted update recoverable.
Q4 Can the MRV416 drive my LED modules?
Diagnosis: A single card loads 512×512 pixels at 60Hz with PWM driver ICs, or 512×384@60Hz with common driver ICs, from an 8bit video source. Solution: Compare your module’s resolution and scan rate against these limits — a P2.5 indoor wall up to about 6.5sqm can be driven by one card. Send us your module size and scan rate, and we will verify the exact card count before you order.
Q5 How many MRV416 cards does my LED wall need?
Diagnosis: Divide the wall’s pixel width and height by 512, rounding each result up. Solution: Example: a 1920×1080 wall needs 4 cards across and 3 down, or 12 cards in total. The practical count also depends on each cabinet’s HUB connector layout and scan rate — share your module size and scan rate for an exact calculation.
Q6 Why is NovaLCT not detecting my MRV416 receiving card?
Diagnosis: Usually a network-layer issue rather than a card fault. Solution: Confirm you run NovaLCT V5.3.0 or later, the PC is on the same subnet as the controller, and no firewall blocks the broadcast/discovery port. Check the running indicator: flashing once per second means the card is healthy and reachable; any other pattern points to the cabling instead.
Q7 How do I choose between the MRV416-N and MRV412 or MRV328?
Diagnosis: The lineup splits by port count and pixel capacity — MRV416-N: 16 HUB75E ports and 512×512@60Hz; MRV412-N: 12 ports at 512×512; MRV328: 8 ports at 256×256@60Hz. Solution: Choose the MRV416-N for 16-port cabinets that need full loading plus 18bit+, Color Management and 1-frame Low Latency; the MRV412-N covers 12-port cabinets at a lighter cost, and the MRV328 remains the EMC-focused choice — all three carry EMC Class A.
Q8 Green indicator flashing every 3 seconds — no display?
Diagnosis: Receiving card is functioning but the Ethernet cable connection is abnormal. Solution: Check the RJ45 cable between the sending card (or previous receiving card) and this card. Verify the connector is fully seated. If using loop backup, check both main and backup Ethernet lines — one may be carrying signal while the other is faulty.
Q9 How do I update the MRV416-N firmware?
Diagnosis: Version check happens inside NovaLCT. Solution: Open NovaLCT V5.3.0 or later, detect the card, and compare the read firmware version against the latest package from NovaStar’s official download center. Batch update your fleet only after testing one card on a spare cabinet — dual program backup makes a failed flash recoverable, but staged rollout is still the safe path.
Q10 What power supply does the MRV416-N need?
Diagnosis: DC 3.8V–5.5V input, either of the dual power connectors. Solution: Use the cabinet’s existing 5V rail — rated current is only 0.5A (2.5W), so the card adds negligible load to your power budget. The red power indicator stays on when input is normal; the card also reports its measured voltage in NovaLCT.
