Author Topic: NEC 900 Firmware Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 04-29-2016 12:57 PM                     Is it safe to upgrade firmware from 3.00 to the latest in one shot?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 04-29-2016 03:52 PM                     I, personally, wouldn't be so bold. In theory, it should work. Are you sure you are on service pack 3.00? That isn't even downloadable anymore. Remember too, on the NC900 some things have to be updated manually via RS232 in conjunction (like the lens firmware...currently on 10). The NC900 wasn't issued with anything less than 4.200 so something sounds fishy here.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-29-2016 06:10 PM                     Seems like someone stuck an ICP in it from an older machine.

These lenses ar more stable than NC-2000 are. Does anyone know what it is supposed to "fix"?

I too haven't had any lens shift failures, but the factory must have seen an issue repeating itself somewhere around the world , and this firmware is designed to prevent further occurrences...  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 04-30-2016 03:25 PM                     Mark, The 900 is VERY inaccurate when it comes to lens positioning, how can you say ZERO problems?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-01-2016 08:10 AM                     The new lens firmware is somewhat interesting but I have had zero lens problems with the NC-900's.

It can't hit its mark...ever. Heck you can't adjust it precisely to begin with. Version 10 of the lens firmware is supposed to fix a corruption potential. That said, I too have not had a problem in version 09.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 05-02-2016 04:57 AM                     Steve, Have you seen a similar issue with the Barco S series? Haven't installed many but it seems that if the two lens positions are far away then no problems; but if Flat and Scope are very close (Flat screen) then the projector seems to struggle to get back to the same spot twice?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 05-02-2016 12:50 PM                     I don't have enough experience with the "S" series to comment one way or the other beyond not noticing a problem but flat/scope lens settings must have been far enough apart. Fortunately, most of our potential "S2K" projectors have bought the better DP2K-12C instead.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 05-03-2016 07:48 AM                     For Barco projectors with almost-identical lens files I break the normal rule of saving after moving in the direction of motion from the other preset - by saving after moving the other way the lens motors go past the target and then back. This seems to make them more repeatable, I think possible with very small movements the drive hysteresis is not fully taken up. Making them go past and back on preset changes eliminates that error.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 05-03-2016 12:55 PM                     Thanks Dave, I'll give it a go next time  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-03-2016 07:28 PM                     My only beef about the NC-900 is the speed of the focus and zoom. Othter wise I've had zero complaints and no focus or zoom drift. Mark  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 05-03-2016 08:02 PM                     It has a bigger problem with vertical and horizontal shift. Though zoom isn't stellar either.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 05-04-2016 01:42 AM                     Mark That's simply untrue. It's a limitation acknowledged by NEC too.  |  IP: Logged
