ackray 0 Posted February 19, 2009 We are trying to put larger drives in this system. So we installed the drives and then ran the restore CD from the Pelco FTP site. The restore cd was the DX800 V2 CD. everything seemed to be fine. However now when we hook up the cameras, to this prior working system, they do not work. Is there hardware incompatibility between the series? In other words does this DVR need need the version 1 restore software? Does it need to be registered? THe manufacture date for this Pelco was March 2004. Does anyone know which version release this would be in? When I exit to the windows shell, there are no device conflicts. EDIT NOTE: Problem solved. The ribbon cable for the 16 port back plane had come lose. Share this post Link to post Share on other sites
