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
