Practical Setup Checklist Using the Ku20 PDF
Before powering up your LED wall, run through this concise checklist derived from the manual:
- Verify power supply voltage matches the Ku20 specification (typically 48 V DC).
- Confirm all data cables are firmly seated and match the indicated pinout.
- Set the correct output resolution in the web UI to match your LED modules.
- Upload the latest firmware version if the current build is older than the release date listed in the manual.
- Run the built‑in self‑test and record any error codes for reference.
Common Questions Answered
Can I use the Ku20 with non‑Novastar LED modules? The manual states the card supports standard 3‑wire and 4‑wire LED strips that conform to the SMPTE 2020 protocol, but compatibility is not guaranteed for proprietary modules.
What is the maximum number of LED modules per Ku20 card? Up to 256 modules (16 × 16 matrix) can be driven, provided the total current does not exceed 30 A per power rail.
How often should I back up the configuration? Novastar recommends exporting the configuration file after any major change and storing it off‑site at least weekly.
Comparison: Ku20 vs. Earlier Novastar Controllers
| Feature | Ku20 | Ku10 (predecessor) |
|---|---|---|
