Dear Friends, I have installed a Vicon Camera the video was coming fine. Then i change some DIP switch to make is Serial Connection with RS422 Support and i am using Pelco D to communicate with it. But when i reinstalled the camera. I see the movement in camera but no video on my PC. The Camera is connected through NVTs to Encoder. I also Noticed that Camera lens is moving around 360 degree as it move when it starts after 2 mins time. Can any body help me in this please
