DP83822I: Configure DP83822 for dual port etherCAT application

Alex Yeh

Part Number: DP83822I

Dear team,

Would you please help to check below DP83822 hardware strap pin configuration for dual port etherCAT application and comment if any advice?

Btw, does it suggested to enable Auto-Negotiation (Advertised Modes) in this application or Force Modes? This is for AC servo drive end-equipment.

Thanks!

Regards,
