NovaStar NV3210 HUB320F Receiving Card
The NovaStar NV3210 uses 10 standard HUB320F connectors for LED module communication. It supports up to 40 groups of RGB real-pixel data, 40 groups of 3-LED sub-pixel data or 30 groups of 4-LED sub-pixel data, with HDR and module flash functions for compatible display systems.
Loading Capacity with M3 and COEX Controllers
Maximum resolution depends on the controller family, driver IC and video bit depth. All figures below are per receiving card at 60 Hz.
| Parameter | Specification |
|---|---|
| PWM IC + M3, 8-bit | 512 × 512 |
| PWM IC + M3, 10-bit / 12-bit | 512 × 384 |
| PWM IC + COEX, 8-bit / 10-bit | 512 × 512 |
| PWM IC + COEX, 12-bit | 512 × 384 |
| Common IC + M3, 8-bit | 512 × 384 |
| Common IC + M3, 10-bit / 12-bit | 256 × 384 |
| Common IC + COEX, 8-bit / 10-bit | 512 × 384 |
| Common IC + COEX, 12-bit | 256 × 384 |

Current and power consumption can vary with settings, use and environment. Check the PDF pin definitions for the selected real-pixel or sub-pixel data mode.
HDR, Calibration and Image Adjustment
The NV3210 supports HDR10 and HLG, Rec.709/DCI-P3/Rec.2020 and custom color gamuts, and 18bit+. Pixel-level brightness and chroma calibration works with the NovaStar calibration system. Quick dark/bright-line adjustment and multi-batch brightness adjustment help address seams and cabinet differences.
One-frame latency at the receiving-card end requires driver ICs with built-in RAM. 3D output requires a compatible 3D controller. Independent RGB gamma adjustment uses NovaLCT and a supporting controller; image rotation is available in 90° increments.
Module Flash and Maintenance
For modules with flash memory, the card supports automatic module calibration, flash management and applying calibration coefficients from module flash. Module auto light-up requires dedicated firmware. LCD-related features also require specialized firmware.
Mapping 1.1 identifies controller, port and receiving-card numbers. Stored images, temperature and voltage monitoring, bit-error detection, firmware readback and configuration readback support maintenance. Reliability functions include dual NCP backup, loop backup, dual configuration backup and dual program backup. Loop backup requires primary and backup line connections.

Frequently Asked Questions
Does the NV3210 use HUB75E or HUB320F connectors?
The NV3210 uses 10 standard HUB320F connectors. Check the exact pin definitions and module wiring in the specification.
Why do NV3210 loading limits differ between M3 and COEX?
The specification gives separate limits by controller family and source bit depth. For example, a PWM driver IC with a 10-bit source at 60 Hz is rated at 512 × 384 with M3 or 512 × 512 with COEX.
Does the NV3210 support HDR?
Yes. The specification lists HDR10 and HLG support. The controller, source and display configuration must be selected for the required workflow.
Is module auto light-up available with standard firmware?
The specification identifies module auto light-up as requiring dedicated firmware and modules with flash memory. LCD-related functions also require specialized firmware.
Which line decoding signals does the NV3210 support?
It supports A, B and C line decoding signals. D and E signals are not supported, as stated in the pin-definition section of the specification.
