MRV560-1 receiving card for LED cabinet replacement
Identify the board and connector layout before replacing an LED receiving card. This NovaStar MRV560-1 listing includes photographs, connector variants and pin references to help compare an existing card with the required replacement. MRV560-1 uses male connectors on the top side; the other MRV560 suffixes identify different connector arrangements.
Replacement checks
- Read the full model and revision from the existing board, including the “-1” suffix.
- Compare connector gender, board side and hub wiring with the diagrams below.
- Retain the cabinet configuration and calibration information before changing hardware.
- Confirm the module data mode and required resolution with the supplier.
Data modes and functions
| Model | MRV560-1, standard top-side male-connector version |
|---|---|
| RGBR′ parallel mode | 16 data groups |
| RGB parallel mode | 20 data groups |
| Serial mode | 64 data groups |
| Original resolution reference | 256 × 226 in the Rev1.1.2 feature list |
| MOM storage | Calibration coefficients and LED module information |
| Service functions | Configuration readback, stored-picture setting and monitoring-card connection |
| Monitored conditions | Temperature, supply voltage and Ethernet communication status |
The 256 × 226 figure is reproduced from the original model document; it is not replaced with a rating from a different MRV card. Verify the required cabinet loading for the supplied board revision.
Calibration and EMC design
The MRV560 family is described as the EMC version of MRV360. Its original specification lists RoHS and CE-EMC Class B compliance. Pixel-by-pixel brightness and chromaticity calibration uses coefficients for individual LEDs. High grayscale and refresh support is listed without a fixed numeric performance promise.
For a general feature overview, see the MRV560-1 receiving-card specifications page. Use the photographs and pin references here when checking a replacement.

Replacement questions
How do I identify an MRV560-1 board?
Check the model label and the top-side male connectors against the product photographs. The suffix is important because other MRV560 variants use different connector genders or positions.
Can I replace an MRV560-2 with an MRV560-1 without checking the hub?
No. The original variant table places male connectors on the bottom for MRV560-2 and on the top for MRV560-1. Confirm the hub arrangement and physical fit before ordering.
What should I save before replacing the receiving card?
Keep the correct cabinet configuration and calibration information. The MRV560 feature list includes configuration-file readback and MOM storage for coefficients and module information.
Are J9 and J10 the same connector?
No. The original references show J9 as a five-pin indicator connector and J10 as a six-pin indicator connector, with different pin assignments. Follow the matching table and board label.
What information helps confirm the correct replacement?
Provide clear board photographs, the full model and revision, hub-board details, cabinet pixel layout and the existing configuration file if available. This helps check fit and configuration instead of relying on the model family alone.
