They did have though the locking screws as opposed to the new design. Also they FINALLY coppied the cooling system which Cinemeccanica and I think Kinoton used in their editions which uses a cooling tank and a pump rather than that bizzare strange pressurised system which you needed an MBA in physics to callibrate correctly!! I think Barcos' approach in the first edition was that ppl would be mounting the projectors on the ceiling!!!!! Demetris  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 05-22-2010 09:57 PM                     I dunno...I took delivery of a DP2000 in December 2009 and it still had the old convergence system. The Manual alluded to the new design but I have never seen it on the series 1. I have mixed views of the pressurized cooling system. Having an inverted mount option would be nice in some installations (put the projector on a lift and have it drop down between the two film projectors when it is needed and tuck back up when done). In truth...the cooling system was easy to figure out once you've done it once or twice. The big thing to remember (other than calibrating the pressure...again easy) is to let it bleed the air out over the course of about an hour. Just let it get the air bubbles out while you do something else. Then pressurize and seal it up. That said...99% of the installations don't need a pressurized system so it is merely a point of failure to be concerned about so I'm good with it going away. I'm not as pleased about the washable filters though. We started with that and people don't clean them as well as they should. While disposables are expensive, they do ensure that the filters are clean, when changed.

You can get a tire pump with a gauge in it and just add one atmosphere of pressure for most conditions.  |  IP: Logged David Favel Jedi Master Film Handler Posts: 764 From: Ashburton, New Zealand Registered: Feb 2002 posted 06-11-2010 01:48 AM                     OK guys, looking for reccomendations for a 3 cinema install. Cinemas 1 & 2 9metre wide screen (29feet) Cinema 3 11metre wide (36feet) At the moment, am leaning towards RealD, NEC and DoReMi. But am really looking for experienced guidance.  |  IP: Logged Demetris Thoupis Phenomenal Film Handler Posts: 1240 From: Aradippou, Larnaca, Cyprus Registered: Apr 2001 posted 06-11-2010 01:59 AM                     It's more a matter of taste really. I would use the Barco DP20C and master image instead of real d. The doremi server is excellent and greatly maneuverable in terms of customization. On the other hand do you want the silver screen? If not then you need a 1,8 gain screen and replace master image with xpand if its brightness you seek more or with dolby 3d correctly callibrated if its quality you seek.

We have installed a bunch under 10m and they look hot! Pretty cost effective too. Master Image is also a good option and on the 11m screen a DP2k15C with 3kw lamp will get you across the line even. You should shop around and get quotes on a variety of configurations before you jump in.  |  IP: Logged Demetris Thoupis Phenomenal Film Handler Posts: 1240 From: Aradippou, Larnaca, Cyprus Registered: Apr 2001 posted 06-11-2010 04:04 AM                     The cost difference between the DP15C and DP20C is minimal. Its better to have the advantage of being able to install a bigger lamp than being at the limit. Also the great benefit of the Barco units is the fact that they can have the Dolby filter wheel embedded in the projector with a lesser cost than the actual Dolby 3D Kit.

For the smallest screens you could go down to a 1.2kW lamp (6000 lumen)  |  IP: Logged Demetris Thoupis Phenomenal Film Handler Posts: 1240 From: Aradippou, Larnaca, Cyprus Registered: Apr 2001 posted 09-28-2010 12:41 PM                     The Doremi server gets a from me. It is built on a basic "windows explorer" platform for the projectionist/operator although it uses a Linux OS. The think I love most is the flexibility of the automation cue creation unlike Dolby DSS unit which simply draws all info from the projector with all the sensless macros being listed, with the Doremi you can select ONLY the ones you want. Also Doremi keeps releasing a lot of updates on their DCP2000 based server and handle any device with ease. Just make sure you have the pkl in your USB drives Demetris  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 02-17-2011 12:47 PM                     Okay, I'll repost it here: I recently read a few setup manuals of series-II projectors. Currently I am lacking manuals for Kinoton and Barco machines. However, I found that the setup options for the Christie series-II are much broader than for NEC series II. The NEC seems to offer the same basic functionality over the WEB interface as on the local machine panel. I am sure the NEC setup options are enough for most simple installations, but I ask myself wether more options are hidden in a special installers menu? The christie has a very well thought out system of access limitations for different grades of users. I don't see anything like that on the NEC. I see the same mentioned for the Barco Communicator software, though I have no idea about the range of Barcos setup options compared to Christie. Any thoughts about the general setup featureset of the Barcos/Kinoton/Cinemeccanica? I'd really like to discuss the setup-differences of the current Series-II machines more deeply. The Barco manuals are not freely downloadable it seems. Maybe someone can make them available in the warehouse download section? I know I can download them after registration with Barco, but it seems you already need to have a Barco machine in order to register. That doesn't help in decision making. - Carsten  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-17-2011 02:46 PM                     NEC and Barco have different user levels too. Though I find that most seem to have the all-access level or the no-access level (all or nothing). It all depends on what features you are looking for as to how limited a projector will seem to be. I've generally found Barco's software to be the most thought out and best but I have not played with the Christie series IIs to see all of the improvements...the web versions of the ZX and M were slow pigs that were most frustrating to work with. The TPC was better but also nothing compared to Barco. NECs software is "okay" but clunky in its layout and not quite as intuitive as it should be but if you keep at it, it can let you do most anything...it is just awkward. -Steve  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 02-17-2011 03:41 PM                     I can't see anything in the NEC series-II setup manuals. All the basic things are there, but no user/access right management. The browser interface just duplicated the minimal LCD-Screen/button interface in functionality. Is there an advanced mode that is not mentioned in the manuals? These manuals are not just an operating guide, they seemed to be meant for installers (lens adjustments, Title settings). The Series-I manuals are more explicit. I'd really like to see what Barco offers. The Christie documentation and functionality is excellent. Interesting question though, as to how much functionality the 'advanced projectionist' should expect to be enabled for him. - Carsten  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-18-2011 06:48 AM                     On the NEC ICC program, they have the "service" level...which I think is the top level. There will be an (s) showing on the main page when you are on that level. It is password protected...I think there are 4 levels total though I have only ever been on the service one. Get an account on my.barco.com and you will have access to all of their manuals. The Communicator has a manual all of its own. Barco manuals are largish (10s of Megabytes, typically) so they might be awkward for uploads/downloads here. Plus, Barco does have them for download (including previous versions, typically). -Steve  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 02-19-2011 01:05 AM                     Barco projectors ship with a "default user" level that the communicator software (on the touchscreen or your computer) boots into and a "service technician" level that lets you do most anything to the projector, including some "bad idea" stuff. There's a root level too, but the password is not given to mere mortals. We have no need for root access anyway... unless we want to "revise" the logs I suppose. You can fairly easily set up your own added user levels with access to whatever functions you want from a list of what the "service technician" is allowed. There's a master key for the Christie Medeco locks, but Christie is pretty tight with them. The Christie marriage procedure is dead simple. With Barco you need the supplied iButton fob and a keypress combination "password" to marry the system after opening a secure cover or removing a board... but a "service technician" can add any iButton rfid fob to the system, set its password, and get on with the marriage. I suppose some DCI regulation requires a key of some sort. The first rule of computer security, though, is "if an attacker has physical access to the computer there is no security". This stuff just makes working on the things more difficult without increasing real security. Hint: the Barco security cover intrusion microswitches are wired as normally closed.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-19-2011 07:30 AM                     Dave, That is a pretty good explanation...I do have access to the root level and its primary function is for the employee with a vengeance that changes passwords on their way out the door. Someone that has root level can restore the passwords to the factory defaults. However, the passwords are referenced to the communicator program, not the projector...so if you are using YOUR copy of the software, you won't be locked out While the security switches are indeed N.C. ... on the backplane of the projector, those cables plug into an area that requires triggering one of the switches...so one would have to plan in advance. It isn't that it is hard to remarry the boards or clear a security issue...however, it WILL be logged and it will also not who did it (another reason I don't like that the Service Tech password is left at the factory setting and is used by most). You have no idea who has been in there...just that someone has. -Steve  |  IP: Logged
