Calculate
Best suited for
- Driving a cabinet or module group of up to 256 × 226 pixels with a single card.
- Permanent installations that need temperature / voltage monitoring.
Key features (manufacturer)
- A single card loads up to 256×226 pixels (as printed)
- Up to 24 sets of parallel RGB data or 64 sets of serial data
- 12-bit precision pixel level brightness and chroma calibration with NovaLCT and NovaCLB
- Quick seam correction and 3D function (with an independent controller that supports 3D)
- Voltage and temperature monitoring without peripherals; bit error rate monitoring with NovaLCT V5.2.0 or later
- Dual power supplies with status monitoring
- Loop backup through main and backup redundant cascading lines
- Dual backup of program; readback of configuration parameters
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 57,856 px.
