Content Summary
This bulletin highlights a compatibility issue with Windows XP SP2 and IEEE 1394b adapters, affecting image acquisition from IEEE 1394 DCAM cameras. SP2 limits IEEE 1394 devices to 100 Mbit/s, impacting Cognex CVL and VisionPro software. Microsoft's hotfix (KB885222) partially resolves this by restoring speeds up to 400 Mbit/s for IEEE 1394a devices. Solutions include using Windows XP SP1 or switching to IEEE 1394a adapters. Contact Cognex Technical Support for assistance.
This technical bulletin addresses a compatibility issue between Windows XP Service Pack 2 (SP2) and IEEE 1394b (FireWire) adapters, affecting image acquisition from IEEE 1394 DCAM cameras connected via IEEE 1394b interface cards. With SP2, all IEEE 1394 devices default to 100 Mbit/s speeds instead of their maximum, impacting Cognex CVL and VisionPro software, which fails to acquire images from IEEE 1394a cameras connected to IEEE 1394b adapters. Microsoft has released a partial hotfix (KB885222) that restores speeds up to 400 Mbit/s for IEEE 1394a devices, sufficient for Cognex software. Alternative solutions include reverting to Windows XP SP1 or replacing IEEE 1394b adapters with IEEE 1394a adapters. For installation issues or further assistance, contact Cognex Technical Support.
