Compatibility Checklist

Matching these points before ordering reduces wrong-selection risk.

  • Compatible with standard & PWM driver IC modules (according to controller ecosystem)
  • Confirm scan mode (static to 1/128) matches your module and controller configuration
  • Use correct port mapping and cabinet-to-cabinet routing plan during commissioning

Installation & Commissioning

Following best practices reduces downtime and makes maintenance easier.

  • Check LED indicators to confirm power and signal status during initial setup
  • Document port mapping/routing for easier future service
  • Use quality CAT5e/CAT6 and proper grounding to reduce noise and flicker risk

Common Issues & Quick Fix

During setup, most issues come from mapping, scan settings, or cable routing.

  • Shift/mirror/tearing -> mapping/scan mismatch; re-check configuration and routing
  • Random flicker -> grounding/noise or unstable power; verify distribution and cable quality
  • No output -> check Ethernet link, port mapping, and ribbon orientation
