MRV412-N: module connections and loading capacity
The NovaStar MRV412-N is a receiving card for LED display cabinets with 12 HUB75E module connectors. It handles up to 24 parallel RGB data groups. Select the cabinet configuration against its module driver IC, wiring and scan requirements; the maximum pixel count alone does not define compatibility.

Configuration and maintenance
Firmware and configuration parameters can be read back and saved to a computer. Keep these records with the module driver IC and scan information when maintaining an existing screen. A file intended for a similarly named receiving card should not be assumed to match the MRV412-N.
Mapping 1.1 identifies controller numbers, receiving-card numbers and Ethernet ports on cabinets. Temperature and voltage monitoring need no external sensing device, while bit-error detection helps identify network communication problems. A 5-pin LCD connection supports cabinet display of temperature, voltage, current run time and total run time.
The card stores configuration parameters in application and factory areas, and retains two firmware copies. Loop backup requires primary and backup network connections to the controller. A custom stored image can be shown at startup, after an Ethernet disconnection or when video is unavailable.
Display adjustment features
Color management covers Rec.709, DCI-P3, Rec.2020 and custom gamuts. 18bit+, pixel-level brightness and chroma calibration, seam brightness correction and multi-batch adjustment help align the appearance of modules and cabinets. Pixel calibration uses NovaStar’s calibration system.
Individual RGB gamma adjustment works with NovaLCT and a supporting controller. A 3D-capable controller is needed for 3D output. Low-latency mode is off by default and reduces receiving-card latency to one frame only when the module driver IC has built-in RAM. The image can rotate by 0°, 90°, 180° or 270°.
MRV412-N and MRV416-N
The MRV412-N provides 12 HUB75E connectors and 24 parallel RGB data groups. The MRV416-N provides 16 HUB75E connectors and 32 groups. Match the port arrangement and module configuration to the cabinet before choosing between them.

Frequently Asked Questions
Does the MRV412-N support 512 × 512 pixels?
Yes, with PWM driver ICs and an 8-bit video source at 60 Hz. With common driver ICs under the same source conditions, the stated maximum is 512 × 384 pixels.
How many LED module connections are available?
There are 12 standard HUB75E connectors with support for up to 24 parallel RGB data groups. The module wiring and scan configuration must also match.
Can I use an MRV412 firmware or configuration file on the MRV412-N?
Do not infer compatibility from the similar name. Match the exact receiving-card model, module driver IC, scan mode and wiring before loading a file. The MRV412-N supports firmware and configuration readback so existing data can be saved for maintenance.
What is the difference between the MRV412-N and MRV416-N?
The documented connector count is 12 HUB75E ports on the MRV412-N and 16 on the MRV416-N. Their supported parallel RGB groups are 24 and 32 respectively. Those differences must be considered alongside the actual module configuration.
How do I display a test pattern without an Ethernet signal?
According to the MRV412-N specification, disconnect the Ethernet cable and press the self-test button twice to display a test pattern. Press the button again to switch patterns. This tests the local display path; it does not confirm the incoming video or network mapping.
