Identify the NovaStar MRV560-1 receiving card
For a replacement or cabinet wiring check, start with the model suffix and connector orientation. MRV560-1 uses male connectors on the top of the board. The MRV560 series is described by NovaStar as an EMC version of MRV360 and supports three selectable output-data arrangements through two 50-pin hub interfaces.
The interface drawings below accompany the original product images. Consult the MRV560 series connector-variant overview when comparing the -1, -2, -3 and -4 versions.
Output modes to match with the cabinet
- 16-group mode: RGBR′ parallel data.
- 20-group mode: RGB parallel data.
- 64-group mode: serial data, with each data cable able to drive one LED bar.
JH1 and JH2 carry different assignments in each mode. Match the selected mode to the complete table in the specification before connecting the hub. Do not infer the signal assignment from connector shape alone.
Electrical and physical reference
| Parameter | Specification |
|---|---|
| Connector variant | Male connectors on top |
| Specified resolution | 256 × 226; no refresh rate stated with this entry |
| Data connectors | Two 50-pin interfaces |
| Voltage, min / typical / max | 3.3 / 5.0 / 5.5 V |
| Current, min / typical / max | 0.33 / 0.5 / 0.55 A |
| Working temperature | −20 to +70 °C |
| Working humidity | 10–90% |
| Board / overall thickness | Approximately 1.7 mm / 19 mm including components on both sides |
The resolution is reproduced exactly from the linked Rev1.1.2 document. Its 256 × 226 entry should not be silently replaced with a figure from another receiving-card series.
MOM, calibration and service functions
The J4 MOM interface is used for calibration-coefficient and LED-module information storage. MRV560 also supports configuration-file readback, stored-picture settings and pixel-by-pixel brightness/chromaticity calibration. Temperature, power-supply voltage and Ethernet cable communication status can be monitored, and a monitoring card can be connected.

Blank J4 entries are left unspecified in the source document; they are not assigned a signal here. Use the original connector diagram to determine orientation.
Frequently Asked Questions
How can I identify an MRV560-1 connector arrangement?
The MRV560-1 variant has male connectors on the top side. Check the complete model marking and compare the board images and connector orientation before selecting a replacement.
Where are the JH1 and JH2 data pin definitions?
The downloadable Rev1.1.2 specification contains separate tables for 16-group RGBR′, 20-group RGB and 64-group serial data. Select the table that matches the cabinet’s configured data mode.
What is the difference between J4 and J9/J10?
J4 is the MOM interface associated with calibration-coefficient and module-information storage. J9 and J10 are indicator connectors with five and six pins respectively; their signal assignments are listed above.
Are blank J4 pins ground connections?
The source leaves those entries blank. They are not identified as ground, so do not assign that function to them. Only entries explicitly marked GND are labeled as ground in the table.
Can I read back configuration and monitor the card?
Yes. The documented functions include configuration-file readback, temperature monitoring, Ethernet communication-status detection and supply-voltage detection, with support for connecting a monitoring card.
