When using Matrox Solios/Radient frame grabber, JAI camera control may perform very slow or even no response, but actually this problem can be solved or at least be improved by change one setting in Matrox Intellicam.
In default mode, Matrox CL frame grabbers outputs random signal through CC1. Camera will be busy to answer this signal, and have no time to answer ASCII commands that user sends.
-Open your dcf file
-Click Menu Digitizer -> Control
-Once open Digitizer Controller dialog, CC1 signal will be fixed.
In dcf file dialog, find "Other" tap, Check "Enable CC output on connector 1", then CC1 signal will be fixed.
When the setting done, you can connect camera without no response.
