CORIOdiscover performs network discovery by broadcasting over UDP port 10001 to identify any CORIO3 device on the same network segment. If CORIOdiscover is not detecting the CORIO3 device, ensure that the PC and target device are on the same segment and the device has fully booted.
Windows Defender firewall may be blocking discovery traffic. Under Allow and App Through Windows Firewall, please make sure that CORIOdiscover and CORIOdiscover.CLI is allowed in all available network types -- Public, Private, etc. Restart CORIOdiscover if it is running. In some rare instances, it may be required to restart Windows for this change to take effect. IT policy may block the ability to make changes to this setting, and the system administrator may required to make the required changes.
