We are still looking for the right connector type to use to get ten or more differential channels in. One suggestion is to use the Camera Linkhttp://solutions.3m.com/wps/portal/3M/en_WW/electronics/home/productsandservices/CameraLink/ standard using individually shielded twisted pairs. But also cheaper alternatives as simple flatcables are considered. One may follow the discussion in the Mailing list or its archives.
