  • Updated
Follow

This article explains how to enable APIPA (Automatic Private IP Addressing) on a GCQuad or QuadMax using the Hardware Diagnostic Tool (HDT).

APIPA is commonly used when troubleshooting direct Ethernet connections between the device and a PC, especially when the device is not receiving an IP address from a network or cannot connect to Foresight Sports software.

  • Foresight Sports software cannot detect or connect to the device

What You’ll Need

  • A Windows PC

  • A USB-C cable (for the USB method)

  • The Hardware Diagnostic Tool (HDT)

💡 macOS is not supported for USB or HDT log retrieval.
