Introduction
The A5s Plus is a general small-size receiving card developed by NovaStar Tech Co., Ltd. (hereinafter referred to as NovaStar). Supporting various functions such as Color Management, 18bit+, Pixel Level Brightness and Chroma Calibration, Quick Adjustment of Dark or Bright Lines, Multi-batch Adjustment, Low Latency, 3D, Individual Gamma Adjustment for RGB, and 90° Image Rotation, the A5s Plus can significantly improve the display effect and user experience.
The A5s Plus uses high-density connectors for communication to limit the effects of dust and vibration, resulting in high stability. It supports up to 32 groups of parallel RGB data or 64 groups of serial data (expandable to 128 groups of serial data). Its reserved pins allow for custom functions of users. Thanks to its EMC Class B compliant hardware design, the A5s Plus has improved electromagnetic compatibility and is suitable for various on-site setups.
- For PWM driver ICs, the maximum load capacity per card is:
- 512×384@60Hz (For 8bit video sources)
- 256×384@60Hz (For 10bit and 12bit video sources)
- For common driver ICs, the maximum load capacity per card is:
- 384×384@60Hz (For 8bit video sources)
- 192×384@60Hz (For 10bit and 12bit video sources)
Certifications
RoHS, EMC Class B
If the product does not have the relevant certifications required by the countries or regions where it is to be sold, please contact NovaStar to confirm or address the problem. Otherwise, the customer shall be responsible for the legal risks caused or NovaStar has the right to claim compensation.
Features
Improvements to Display Effect
- Color Management: Support standard (Rec.709 / DCI-P3 / Rec.2020) and custom color gamuts, enabling more precise colors on the screen.
- 18bit+: Improve the LED display grayscale by 4 times to avoid grayscale loss due to low brightness and allow for a smoother image.
- Pixel Level Brightness and Chroma Calibration: Work with NovaStar's calibration system to calibrate the brightness and chroma of each pixel, effectively eliminating differences and enabling high consistency for both brightness and chroma.
- Quick Adjustment of Dark or Bright Lines: The different brightness of seams caused by splicing of modules or cabinets can be corrected to improve the visual experience. The correction is easy and takes effect immediately.
- Multi-batch Adjustment: Adjust the brightness of cabinets or modules to minimize display discrepancies caused by variations in production batches.
Improvements to Maintainability
- Smart Module (dedicated firmware required): Work with the smart module to support module ID management, storage of calibration coefficients and module parameters, monitoring of module temperature, voltage and flat cable communication status, and LED error detection.
- Automatic Module Calibration: After a new module with flash memory is installed to replace the old one, the calibration coefficients stored in the flash memory can be automatically uploaded to the receiving card when it is powered on, which ensures unchanged uniform display brightness and chroma.
- Uploading Calibration Coefficients: Upload calibration coefficients to the receiving card quickly or in a stable manner, with acceleration support if needed.
- Module Flash Management: For modules with flash memory, the information stored can be managed, allowing for the storage and readback of calibration coefficients and module IDs.
- One-click to Apply Calibration Coefficients in Module Flash: For modules with flash memory, when the Ethernet cable is disconnected, users can hold down the self-test button on the cabinet to upload the calibration coefficients in the memory of the module to the receiving card.
Improvements to Reliability
- Dual Card Backup and Status Monitoring: In an application requiring high reliability, two receiving cards can be mounted onto a single hub board for backup. When the primary card fails, the backup card can serve immediately to ensure uninterrupted operation of the display.
- Loop Backup: The receiving card and controller form a loop via the primary and backup line connections. When a fault occurs at a location of the lines, the screen can still display the image normally.
- Dual Backup of Configuration Parameters: The receiving card configuration parameters are stored in the application area and factory area of the receiving card at the same time. Users usually use the configuration parameters in the application area. If necessary, users can restore the configuration parameters in the factory area to the application area.
- Dual Program Backup: Two copies of firmware program are stored in the receiving card at the factory to avoid the problem that the receiving card may get stuck abnormally during program update.
Appearance
The A5s Plus receiving card features a compact design. The top view shows the NovaStar logo and the product name 'A5s Plus', along with a Power Running Indicator and a Power Indicator. The bottom view highlights High-Density Connectors. All product pictures shown in this document are for illustration purpose only. Actual product may vary.
Indicator
| Indicators | Color | Status | Description |
| Running indicator | Green | Flashing once every 1s | The receiving card is functioning normally. Ethernet cable connection is normal, and video source input is available. |
| Flashing once every 3s | Ethernet cable connection is abnormal. | ||
| Flashing 3 times every 0.5s | Ethernet cable connection is normal, but video source input is unavailable. | ||
| Flashing once every 0.2s | The receiving card failed to load the program in the application area and is now using the backup program. | ||
| Flashing 8 times every 0.5s | A redundancy switchover occurred on the Ethernet port and the loop backup has taken effect. | ||
| Power indicator | Red | Always on | The power input is normal. |
Dimensions
The board thickness is not greater than 2.0 mm, and the total thickness (board thickness + thickness of components on the top and bottom sides) is not greater than 8.7 mm. Ground connection (GND) is enabled for mounting holes.
Dimensions are provided in millimeters (mm) with a tolerance of ±0.3 mm.
A diagram illustrates the dimensions: 70.0 mm (length) x 45.0 mm (width) x 8.3 mm (thickness). Other measurements include 3.7 mm, 8.3 mm, 1.6 mm, 5.8 mm, 60.5 mm, 3.8 mm, 70.0 mm, and 4 Ø3.2 mm for mounting holes.
Note: The distance between outer surfaces of the product and hub boards after their high-density connectors fit together is 5.0 mm. A 5.0 mm copper pillar is recommended.
To make molds or trepan mounting holes, please contact NovaStar for a higher-precision structural drawing.
Installation
Please refer to the diagram below. Hold the product securely from the sides (long edges) near the center, and press it into the HUB board to install.
? Caution: The product's static resistance is 2 kV. Be mindful of static protection during handling.
