RV12S

INTRODUCTION

• The RV12S is a general receiving card developed by TWT Tech Co., Ltd. (hereinafter referred to as TWT). A single RV12S supports resolutions up to 512×384@60Hz (TWT V5.3.1 or later required). It supports various features such as pixel-level brightness and chroma calibration, quick adjustment of dark or bright lines, 3D functionality, individual gamma adjustment for RGB, and image rotation in 90° increments. The RV12S can significantly enhance display performance and user experience.

• The RV12S uses 12 standard HUB75E connectors for communication and supports up to 24 groups of parallel RGB data. On-site setup, operation, and maintenance were all taken into account when designing the hardware and software of the RV12S, allowing for an easier setup, more stable operation, and more efficient maintenance

FEATURES

Improvements To Display Effect

• Pixel level brightness and chroma calibration
  Work with TWT's high-precision calibration system to calibrate the brightness and chroma of each pixel, effectively removing brightness differences and chroma differences, and enabling high brightness consistency and chroma consistency.
• Quick adjustment of dark or bright lines
  The dark or bright lines caused by splicing modules and cabinets can be adjusted to improve the visual experience. The adjustment can be easily made and takes effect immediately.
• 3D function
  Working with the sending card that supports 3D function, the receiving card supports 3D image output.
• Individual gamma adjustment for RGB
  Working with TWT (V5.2.0 or later) and the controller that supports this function, the receiving card supports individual adjustment of red gamma, green gamma and blue gamma, which can effectively control image nonuniformity at low grayscale conditions and white balance offset, allowing for a more realistic image.
• Image rotation in 90° increments
  The display image can be set to rotate in multiples of 90° (0°/90°/180°/270°).

Improvements to Maintainability

• Mapping function
  The cabinets can display the receiving card number and Ethernet port information, allowing users to easily obtain the locations and connection topology of receiving cards.
• Setting of a pre-stored image in receiving card
  The image displayed on the screen during startup, or displayed when the Ethernet cable is disconnected or there is no video signal can be customized.
• Temperature and voltage monitoring
  The receiving card temperature and voltage can be monitored without using peripherals.
• Cabinet LCD
  The LCD module of the cabinet can display the temperature, voltage, single run time and total run time of the receiving card.
• Bit error detection
  The Ethernet port communication quality of the receiving card can be monitored and the number of erroneous packets can be recorded to help troubleshoot network communication problems. TWT V5.2.0 or later is required.
• Firmware program readback
  The receiving card firmware program can be read back and saved to the local computer. TWT V5.2.0 or later is required.
• Configuration parameter readback
  The receiving card configuration parameters can be read back and saved to the local computer.

Improvements to Reliability

• Loop backup
  The receiving card and sending card form a loop via the main and backup line connections. If a fault occurs at a location of the lines, the screen can still display the image normally.
• Dual program backup
  Two copies of firmware program are stored in the application area of the receiving card at the factory to avoid the problem that the receiving card may get stuck abnormally during program update.
