Author Topic: Anyone using NC900-A with Doremi IMB, were having HDSDI trouble. Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 02-01-2013 02:52 PM                        Doremi confirmed the HDSDI should be working but we get nothing. Internal and HDMI are working fine. This is the IMB/Show vault combo. Same video path works with another cinema projector so the issue is definitely not the signal. Anyone having any luck feeding serial to the NEC 900? Doremi had us run a few tests and through the process of elimination the issue is pointing to the projector. Any special setup needed in the NEC for serial. I am sure we have everything set properly but there is always chance for human error.  |  IP: Logged Tom Bert Expert Film Handler Posts: 134 From: Belgium Registered: Apr 2010 posted 02-05-2013 10:01 AM                     What are you playing back over the SDI inputs? It will not accept DCPs from 'old servers' since the SDI inputs on the IMB are not connected to the decryption.  |  IP: Logged Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 02-05-2013 05:39 PM                        Tom alternative content 1920 x 1080p 23.98 The same video source/chain fed to a duel hdsdi card non IMB works fine.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 02-07-2013 04:01 PM                     Did you gointo the IMB setup on the server and select that input?  |  IP: Logged Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 02-07-2013 11:50 PM                        Yes, all IMB switching is done via the Doremi Showvault not the projector.  |  IP: Logged Chris Milton Film Handler Posts: 6 From: London, UK Registered: May 2012 posted 03-08-2013 05:52 AM                     I had the same problem with a Doremi IMB/Showvault and a Christie projector. For some reason you have to change the input on the projector to IMD-SDI. You don't have to do this when switching from internal to HDMI but for SDI you do.  |  IP: Logged Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 03-08-2013 09:51 AM                        quote: Chris Milton I had the same problem with a Doremi IMB/Showvault and a Christie projector.

I will give that a try, thanks for chiming in!  |  IP: Logged Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 03-08-2013 12:13 PM                        A few questions, so far no luck. What input do you have selected on the projector, Duel HDSDI or 292a/b. My 292 is greyed out I can only select Duel HDSDI. Do you still have to select HDSDI in the server or do you leave it set for "internal" or "HDMI"? Thank you!  |  IP: Logged
