NovaStar DH426 LED Receiving Card | 16 HUB75 Ports
Original price was: $ 19.00.$ 18.20Current price is: $ 18.20.
The NovaStar DH426 receiving card connects LED modules through 16 standard HUB75 ports and supports up to 32 groups of parallel RGB data. Its V1.1.0 specification lists up to 512 × 384 pixels with PWM driver ICs or 384 × 384 with general driver ICs.
DH426 Receiving Card for HUB75 LED Cabinets
The NovaStar DH426 is a general-purpose LED receiving card with 16 standard HUB75 connectors. It handles up to 32 groups of parallel RGB data and provides brightness calibration, cabinet mapping and network diagnostics through NovaLCT.
The specifications below come from the original linked V1.1.0 document, dated April 10, 2020. Its stated maximum loading capacity requires NovaLCT V5.3.0 or later; choose the loading limit for the module’s driver IC.
| Parameter | Specification |
|---|---|
| Output connectors | 16 × standard HUB75 |
| Parallel RGB data | Up to 32 groups |
| Maximum loading: PWM driver IC | 512 × 384 pixels |
| Maximum loading: general driver IC | 384 × 384 pixels |
| Input voltage | 3.3–5.0 V DC |
| Rated current / power consumption | 0.5 A / 2.5 W |
| Dimensions | 145.6 × 91.5 × 16.8 mm |
| Net weight | 100.1 g |
| Operating temperature | −20°C to +70°C |
| Operating humidity | 10–90% RH, non-condensing |
| Storage temperature | −25°C to +125°C |
| Storage humidity | 0–95% RH, non-condensing |
Calibration and Display Adjustment
Brightness calibration works with NovaLCT and NovaCLB to improve consistency across individual LEDs. Dark and bright seam adjustment in NovaLCT addresses visible lines caused by cabinet or module joins, with changes taking effect immediately.
For independent RGB Gamma adjustment, use a supporting controller and NovaLCT V5.2.0 or later. The 3D function also needs a compatible controller and the appropriate 3D settings; the receiving card alone does not provide a complete 3D system.
Configuration, Monitoring and Backup
Mapping displays receiving-card numbers and Ethernet-port information on the target cabinets to help identify wiring. NovaLCT can show the card’s temperature and voltage without extra monitoring peripherals, and read back firmware and configuration parameters for local storage.
Bit-error monitoring requires NovaLCT V5.2.0 or later. It checks communication between a sending device and receiving card, or between receiving cards. Loop backup uses primary and standby network paths; the second path takes over if one fails. The card also stores two application programs as a safeguard during program updates.
Frequently Asked Questions
How many HUB75 ports does the DH426 have?
It has 16 standard HUB75 connectors and supports up to 32 groups of parallel RGB data. Check the interface diagram in the PDF against your module pinout before connecting it.
What is the maximum resolution of a NovaStar DH426?
V1.1.0 lists 512 × 384 pixels with PWM driver ICs and 384 × 384 pixels with general driver ICs. NovaLCT V5.3.0 or later is required for the stated maximum loading capacity.
What power supply voltage does DH426 require?
The linked V1.1.0 specification gives an input range of 3.3–5.0 V DC, rated current of 0.5 A and rated power consumption of 2.5 W.
Can DH426 show 3D content on its own?
No. Its documented 3D function needs a controller that supports 3D, with the function enabled and configured in NovaLCT or on the controller.
Where can I download the DH426 specification and check the pinout?
The original Chinese V1.1.0 PDF is linked below. It includes the interface pinout, dimensions, indicator states and electrical specifications. It is a specification document, not a firmware download.
