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
