Author Topic: DA-20 How to set the A-Chain Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 08-26-2004 10:08 PM                     Dean, yes same cable assuming you buy a null converter to put on one end of it for using with SDDS. Otherwise just buy two cables and mark them DOLBY or SONY. I think Mark has been smoking some of that I-30 stuff. I haven't seen SRD track printing quality get better or worse over the years. It's always been fine.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-26-2004 10:29 PM                     There's no I-30 here, just I-40 and I-15!

DTS & SDDS: Cross over (null modem) 9 pin serial female to female. You can buy them at any computer shop, Fry's, Best Buy, whatever. Or you can make your own.  |  IP: Logged Dean Kollet Jedi Master Film Handler Posts: 591 From: Florida State University Registered: Jul 2003 posted 08-26-2004 11:51 PM                     same cable for DTS and SDDS?  |  IP: Logged Robb Johnston Expert Film Handler Posts: 147 From: St. Louis Suburbs Registered: Nov 1999 posted 08-27-2004 12:41 AM                        except for a null modem on the SDDS (both 2000 and 3000 and 3000 reader calibration)  |  IP: Logged Ferdinando Innocenti Film Handler Posts: 79 From: Genova / Italy Registered: Jun 2004 posted 08-27-2004 01:02 AM                     Dean, the cable is not the same for SDDS: for Dolby connections it's a pin to pin cable (1 to 1, 2 to 2, and so on), for Sony connections is a null modem cable; loook at here for a scheme: http://www.loop-back.com/null-mod.html Ciao Nando  |  IP: Logged Josh Jones Redhat Posts: 1207 From: Plano, TX Registered: Apr 2000 posted 08-27-2004 03:16 AM                        We run late run art stuff up here, used to track 5-6 regularly. used beat up print of The story of the weeping camel is tracking 0-1-2 here, with film guard of course. I also noticed a difference at the house when I started using the stuff. Meanwhile at the plex, the lowest I see is 3, many are hovering around 6.

All you really need is one straight through serial cable and a null modem adaptor that you can buy at Rat Shack. This makes for less of a tangle in your sound case.

Thanks Nando  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-27-2004 07:52 PM                     Fernando, No need to appologize for your English. Its actually VERY good! "Straight through" is just another way to say it. "Pin to pin" is also good. I have to wonder how many people in other countries are worried about posting here because thay may think their english is bad but in reality it is very good.... I'd bet there are many! I would like to see more people from other countries post here.

I said to the 'tech', "I have asked some 'friends' about it and they suggested replace the bulb." He just says "no, it was the power supply, I tested the voltages" - whatever that means. (I don't know at that point if he was refering to the da-20 or the cat700). I said "well its not working". As far as he knew the thing was fixed. But everyone was bypassing it and had the cat 700 turned off. I'm cutting very long story short here, believe me. Only 1 of the 30 screens (spread over three close locations of the same company) has a cat700, the rest are basement, oh 2 are DTS (dont ask) on Vic5's. Problem, we have no spare bulbs, so I had a look at the bulb currently in the reader, I couldn't really see any fogging or dis-colouring, and having no new bulb to compare it to, I decided to rotate the lamp 45 degrees and also make sure it was seated properly. (Hmm, I know where to get a new bulb, YOU reading this BRETT?? - Better hide the spares) Next session all I was getting was the '-' and thought F&*k, and thinking at reboot all I'll get is F. But WHOA at reboot, it was coming in at 6. jumping to F then settled to 5.5/5.0 or even as low as 4. However it would flash to F. for a milisecond too many times my for liking to let the show actually run in SRD. Next session it started '-' again, but after a re-boot sat on nice 4-5, but still jumped to 6. then f. at times. (The print was a quite new Peter Sellers, not a 9/11 that I don't think anyone can run in SRD anymore) One note though, the tiny LED's on the DA-20 in the top right (L-C-R-LS-RS-SW) barely ever flash, all the other DA-20's (with basement readers flash like crazy), is that another indication the bulb is at fault? So the new bulb idea sounds right to me. If only I could convince the 'tech' of that. The rebooting it (the DA-20) each show seems strange though. I'll do more research, when I'm next there to put a in new bulb. (hello BRETT - Hide 'em mate)  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 08-31-2004 05:42 PM                     Yes Bill, change the bulb. The worst thing that could possibly happen is that it did not fix the problem and you now have a spare. oooooh, what a horror!  |  IP: Logged
