We have a customer who is trying to daisy chain 4 Sony EVI-HD7V cameras to a C90, and he is finding that the codec will only detect the first camera. I know the C-series codecs support the EVI-HD7V since TC3, but I have not been able to find any documentation on daisy-chaining them. Are there any caveats that he should be looking out for, or any special configuration of the C90 (or the cameras for that matter)?
Please refer the chapter 4 of the document Cisco TelePresence PrecisionHD Camera
Also please remember to use cisco provided daisy chain cable if not make sure about your custom made cable.
Thanks and Regards,
