Machine Protection From Electromagnetic Interference in Industrial and High EMI Areas

Industrial EMI is broadband and high-power. Use industrial-grade power line filters and higher-rejection RF filters.

Four methods without specialized equipment: revenue analysis, smartphone WiFi analyzer, process-of-elimination, test filter.

Handheld RF transmitters inject commands via communication cables. RF filters block the attack signal at the port.

Real arcade testing validates devices in actual RF environments, temperature/humidity, and with specific machine models.

Dense urban venues have 50-100 WiFi APs nearby. Protect with sharp-cutoff RF filters, ferrite beads, and cable shielding.

Bluetooth at 2.4GHz can cause false payout commands. RF filter below 2.4GHz eliminates the interference.

Select RF filter cutoff above machine communication frequency but below wireless band. Install close to port for best effect.

High wireless traffic causes RF energy on communication cables. Use sharp-cutoff filters plus ferrite beads for protection.

External hardware protection works on all machine operating systems. Only connector type and frequency band matter.

Pre-configured devices arrive ready to use. RF filters are pre-configured by design. Bus monitors need manufacturer pre-loading.
