DH418 HUB75 LED Receiving Card
The NovaStar DH418 receives display data for LED modules through eight standard HUB75 interfaces. It supports up to 16 groups of parallel RGB data and a maximum normal load of 256 × 256 pixels per card. Before selecting a replacement, compare the module pinout, driver IC, mounting dimensions and cabinet configuration.

Calibration and 3D Requirements
Pixel-level brightness and chroma calibration works with NovaLCT and NovaCLB to reduce brightness and color differences. NovaLCT also provides immediate adjustment of dark or bright lines at module and cabinet joins.
For 3D, use a controller that supports the function, enable it in NovaLCT or on the controller, and configure the 3D parameters. The specified 3D capacities are lower than the normal 256 × 256 load: 192 × 256 for PWM driver ICs and 176 × 256 for general driver ICs.
Feature verification note: The original listing mentioned independent RGB Gamma adjustment. The linked V1.0.0 document does not confirm that feature; check the supplied hardware, firmware and controller before relying on it.
Setup and Maintenance in NovaLCT
Mapping displays receiving-card numbers and Ethernet-port information on the cabinets. A stored image can be used at startup, when the network cable is disconnected or when no video source is available. The card reports its own temperature and voltage without extra monitoring peripherals and supports a cabinet LCD for temperature, voltage and operating-time information.
Bit-error monitoring requires NovaLCT V5.2.0 or later and helps locate communication problems. Firmware and configuration parameters can be read back and saved locally. Loop backup needs primary and standby network paths; configuration and application-program backups provide additional recovery options.
Frequently Asked Questions
How many LED pixels can a DH418 receiving card load?
The original V1.0.0 specification lists a maximum normal load of 256 × 256 pixels. The 3D limits are 192 × 256 with PWM driver ICs and 176 × 256 with general driver ICs.
Does DH418 use HUB75 connectors?
Yes. It has eight standard HUB75 interfaces and supports up to 16 parallel RGB data groups. Use the PDF pinout to check your LED modules before connecting them.
What input voltage is specified for DH418?
V1.0.0 specifies 3.3–5.0 V DC, a rated current of 0.5 A and rated power consumption of 2.5 W.
Can DH418 display an image when the video signal is lost?
Yes. NovaLCT can store an image for startup, a disconnected network cable or absence of a video source. Configure the required stored image before use.
Where are the DH418 pinout and status LED meanings documented?
The original Chinese specification linked below includes the HUB75 interface diagram, physical dimensions and indicator-state explanations. It also covers loading limits and supported maintenance functions.
