Compatibility Checklist
Matching these points before ordering reduces wrong-selection risk.
- Works with common driver IC modules; supports most PWM IC modules (system dependent)
- Confirm scan mode and mapping configuration in your controller/sender software
- Use quality CAT5e/CAT6 and proper grounding to reduce flicker/noise risk
Installation & Commissioning
Following best practices reduces downtime and makes maintenance easier.
- Label and document HUB port mapping for easier future service
- Run the built-in screen test during commissioning to verify uniformity and flatness
- Keep clean cable routing and strain relief to reduce connector stress
Common Issues & Quick Fix
During setup, most issues come from mapping, scan settings, or cable routing.
- Flicker/noise -> check grounding, DC distribution stability, and cable quality
- Shift/mirror -> re-check scan/mapping configuration and HUB port mapping
- No data -> verify Ethernet link LEDs and sender-to-receiver routing order
