Calculate
Best suited for
- Driving a cabinet or module group of up to 256 × 256 pixels with a single card.
- Permanent installations that need temperature / voltage monitoring.
Key features (manufacturer)
- A single card loads up to 256x256 pixels
- 8 standard HUB75 connectors on the card; a HUB board is unnecessary
- Gigabit Ethernet port that can connect to the PC
- Pixel level brightness and chroma calibration on NovaLCT
- Pre-stored images for startup, Ethernet cable disconnection and no video source signal
- Status detection of temperature, voltage, Ethernet cable communication and video source signals
- Supports NovaStar's general 5-pin LCD module
- Readback of the configuration file and firmware version on NovaLCT
Capacity and loading area
The card receives data over the Ethernet chain and drives the module group inside this area. The cabinet/module load cannot exceed this area or the capacity of 65,536 px.
