Author Topic: BARCO - CHEAP PLUG Allan P. Barnes Film Handler Posts: 4 From: Grand Bend, Ontario, Canada Registered: Jan 2006 posted 07-09-2014 09:57 PM                        FILE THIS UNDER "BARCO KNOWN ISSUE #2" On the rear of the Barco model 1200+1500+2000 digital projectors is a very cheap little multi-pin plug. The TOUCH SCREEN MONITOR plugs in here. This monitor is overpriced but useful - and not required for daily use. IF you use this plug more than once it is HIGHLY PROBABLE you will blend one or more of these little tiny BRASS/COPPER PINS. RESULT you will blow (aka destroy) an entire TI BOARD. Cost to replace the board $1200usd. PLUS the skilled labour (6-8 hours) to reinstall new software and new addresses .. to make old boards talk to new TI Board. Barco is a good product line but this is one very cheap ass plug. NOW here is what I really hate about ... on the nose of these same BARCOS is a very nice heavy duty multi-pin CANNON type XLR  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 07-09-2014 11:33 PM                     Yep, been there and done that with that socket by accidentally bending those pins in the socket when attaching the monitor. Luckily, I have a small pair of needle nose pliers to straighten things out. The keyway for this socket is hard to see, but once you know where the keyway is in proportion to the cable, the connection becomes easy. I power the projector down before connecting the monitor to this socket. I carry a monitor around to connect to my 15 BARCOS when doing bulbs so I do my on-board stuff when doing the changes. -Monte  |  IP: Logged Allan P.

It would be a simple fix to upgrade the plug to an good solid XLR... like the one on the nose. My solution - return the TOUCH SCREEN MONITOR and use a Lamp top with the Barco Com.Program.  |  IP: Logged John Roddy Expert Film Handler Posts: 114 From: Spring, TX, United States Registered: Dec 2012 posted 07-10-2014 12:31 AM                        I always wondered why they didn't just use a single ethernet cable for all of it. It should be possible to run power and connectivity through a single cable. The port currently has eight pins, and that's with serial support. Anyway, it is pretty tough to break them once you get an understanding of how fragile they are. I've also only seen one board fry over the bent pins, and that's just because someone tried to bend them back without powering down the projector first. On the other hand, the series-II ports are a LOT easier to replace. Soooo, there's that. Still an iffy design in the first place, but it now takes two minutes to fix as opposed to spending hours dissecting the entire projector.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 07-10-2014 03:31 AM                     it is indeed a little fragile but if you don't push hard while looking for the position pin it's fine. I'd say 50/50 here, choose a better socket and use the equipment properly! Also, why would you use that socket more than once?  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 07-10-2014 07:07 AM                     quote: Marco Giustini Also, why would you use that socket more than once?

Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 07-10-2014 07:22 AM                     I'd say anyone that is buying one touchpanel for multiple projectors is "doing it wrong." Either have the touchpanel on all projectors or NONE. If you are wanting to just have one device to save money (understandable), then buy a MUCH cheaper PC and load the FREE software on it...they even have it in Linux so you could probably repurpose some obsolete laptop back into service...use that by going around theatre to theatre...Barco does give you 3-4 Ethernet jacks on each projector. The multipin XLR connector is actually for an anamorphic lens mover that never came to be in the series 2 projectors or the .98" series 1. Note, in the series 2 projectors, they moved it to the Cinema Controller board. Its a shame they didn't do anything with that...but that is for another discussion. I suppose it could be re-purposed for a 3D mover but most are using the GPIO connector for that sort of thing. As for what connector to use...I can't defend the one they chose or putting the pins on the projector side if that has the potential to do damage...however, I don't know if Ethernet would have been the best choice either. They have a bit of current going on to power the touchpanel and they have to supply Ethernet and RS232...so you have 4-5 wires just on the power/RS232 alone. If you have an RJ45 you have the potential for people to plug the wrong thing in too. And if you are going to make it a proprietary scheme to accommodate all of the functions, that would make it a HUGE liability.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 07-11-2014 09:41 AM                     I think on the S1 projectors the connector has to come out to remove the rear cover. It is pretty easy to not use it, you need a 12V power supply but the S1 has a power outlet on the control panel. Then an ethernet cable and a serial cable if you need serial - that's required oif you lose the IP address (internally or forget it). Having the pins short should not fry a card. That's bad design and easy to avoid.  |  IP: Logged Darryl Spicer Film God Posts: 3250 From: Lexington, KY, USA Registered: Dec 2000 posted 07-11-2014 10:29 AM                    We just use the RS232 serial port on the controller board and a separate matched power supply for the touch panel that we have.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-11-2014 01:05 PM                     Agreed! I always use Communicator to change a lamp in a Barco.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 07-11-2014 02:08 PM                     Where we have touchpanels in use it is on all projectors...which is typically just the 1 screen. The touchpanel becomes more of an integral player and the theatre typically has more than the 6 or so buttons on the projector. In our typical multis...no touchpanels...but we do offer a cheaper alternative by having a purpose built computer at each projector and an KVM switch so the monitor/keyboard used for the server can also be for the projector.  |  IP: Logged Rick Raskin Phenomenal Film Handler Posts: 1100 From: Manassas Virginia Registered: Jan 2003 posted 07-11-2014 05:48 PM                     I once got my ass roasted at a standards meeting when I referred to an 8 pin modular connector as an RJ-45. I was duly informed that RJ-45 is a specific implementation using an 8P8C modular connector.  |  IP: Logged
