DBSTAR HRV11| HRV11S| DBS-HRV11E| DBS-HRV11MN LED Display Receiving Card Description

The DBSTAR HRV11, HRV11S, DBS-HRV11E, and DBS-HRV11MN LED Display receiving cards are engineered for reliable, high-performance LED display control across a wide range of applications. Supporting single-color, dual-color, full-color, real-pixel, and virtual-pixel panels, these cards deliver high refresh rates, flexible resolution options, broad LED driver compatibility, and built-in diagnostics for stable long-term operation. Designed for rental, fixed installation, and outdoor commercial displays, the HRV11 family emphasizes signal quality, system protection, and easy integration with fiber and copper transmission networks.

Product Features:
• Broad screen type support: single-color, dual-color, full-color, real pixel and virtual pixel displays.
• Wide LED driver compatibility: supports MBI5026, MBI5030, MBI5036, MBI5039, MBI5042, MBI5050, MBI6024 and similar drivers.
• High gray-scale options: supports 4096 (4K) and 65536 (64K) gray levels for smoother gradients and better image quality.
• High refresh performance: typical 180Hz refresh, scalable to higher rates (up to 3600Hz with compatible drivers such as MBI5042) for flicker-free video and stable camera capture.
• V-PWM3 advanced signal processing: improved PWM handling for accurate color rendering and brightness control.
• Real-time diagnostics: monitors voltage, cable errors, and module temperature to alert and protect the system.
• Error detection: open-circuit and short-circuit pixel detection for faster maintenance.
• Relay-controlled fan management: integrated relay output for automated fan control and improved thermal management.
• Scalable transmission: supports long-distance fiber transmission (multi-mode up to 500 m, single-mode up to 10 km) and large installation sizes (supports up to 100 receiving cards per connection chain).
• PWM brightness adjustment: 256-step PWM brightness control, compatible with external brightness sensors for adaptive display brightness.

Installation & Compatibility Notes
• Ensure LED driver compatibility before deployment; some advanced refresh capabilities (e.g., 3600Hz) require specific drivers such as MBI5042.
• For long-distance transmission, use appropriate single-mode fiber and ensure connectors and transceivers are matched for 10 km links.
• Use available diagnostic outputs during commissioning to pre-check module voltages, cable continuity, and temperature alarms.
