MRV208-N LED Receiving Card
The NovaStar MRV208-N connects LED modules through eight standard HUB75E connectors and supports up to 16 groups of parallel RGB data. Its display tools include color management, 18bit+, pixel-level brightness and chroma calibration, seam correction and multi-batch adjustment.
Loading capacity depends on the driver IC and video bit depth. The capacities below are specified for use with M3 controllers; they should not be treated as an unconditional rating for every controller and module combination.

Calibration and Display Adjustment
Working with NovaStar’s calibration system, the card adjusts individual pixel brightness and chroma. Quick dark/bright line adjustment addresses seams between modules or cabinets, while multi-batch adjustment reduces brightness differences between production batches. Individual red, green and blue gamma adjustment requires NovaLCT and a controller that supports the function.
Low-latency mode can reduce latency at the receiving-card end to one frame only when the module driver IC has built-in RAM. This is not an end-to-end system latency specification. 3D output requires a controller with 3D support.
Maintenance and Backup
Mapping 1.1 displays controller, receiving-card and Ethernet-port information on cabinets. Data group mapping helps identify module connections. Temperature/voltage monitoring, bit-error detection, firmware readback and configuration readback support commissioning and maintenance.
A stored image can be set for startup, a disconnected Ethernet cable or loss of video signal. The cabinet LCD connection can show temperature, voltage and running time. Calibration coefficients can be uploaded, read back, saved to hardware or erased.
Loop backup uses primary and backup cabling between the controller and receiving cards. Configuration parameters are stored in both application and factory areas, and dual firmware programs provide a backup during program updates.

Frequently Asked Questions
What is the maximum loading capacity of MRV208-N?
With M3 controllers, PWM driver ICs support up to 512 × 512 at 60 Hz for 8-bit sources or 512 × 256 for 10-bit sources. Common driver ICs support 512 × 384 or 512 × 192 respectively, also at 60 Hz.
How many HUB75E connectors does MRV208-N have?
It has eight standard HUB75E connectors and supports up to 16 groups of parallel RGB data. Check the module pin definition and required data grouping before installation.
What is required for one-frame low latency?
The module driver IC must include built-in RAM. The one-frame figure applies to latency at the receiving-card end; other stages of the video system add their own latency.
Does MRV208-N support pixel-level color calibration?
Yes. It works with NovaStar’s calibration system for pixel-level brightness and chroma calibration. It also supports color management, seam adjustment and multi-batch brightness adjustment.
What backup functions are available?
The card supports loop backup, dual storage of configuration parameters in application and factory areas, and dual firmware program backup. Loop backup requires the corresponding primary and backup cable connections.
