Barco 9xx flash memory back up

Youre still obsessed with that board arent you...

Tell me true man? Why is it when i had 909 v3.12 software my fans ran fast with and without the so called fan control board???

Why is it my CineMAX v2.0 ran them slow with and without the fan controller board???

Why did flashing software to Cine 9 v2.21 make the fans run slow and quiet with or without the so called fan controller board???

909 v2.21 is NOT THE SAME as Cine 9 v2.21...

Honestly... How many more times???

Thanks. Now it makes sense.

Yeah it was, many moons ago. Im not sure if it was this forum though. Id have thought it would be pretty obvious to any Cine 9/909 user though, the menus look different for a start, so its plain to see the software is clearly not the same.

The version number indicates the version of the software for whatever designation, Cine 9 or 909, Cine 9 software has a few extra home user features that 909 software does not, as well as running the fans slower and the scan limit is 130kHz, instead of 180kHz for the 909, which no one here could ever make use of anyway, and theyre only kidding themselves if they think they will.

All i did to make mine run quiet was ditch the 909 software for the Cine 9 software. With or without the boards Redfox is refering to, the fan speed followed the software designation only. The CineMAX software ran the fans slow and quiet even without the boards, and the 909 software ran them fast, regardless of the boards being there or not.


Any version of Cine 9 software should provide the same result. Considering there was no functionality improvement for 909 v3.12 over Cine 9 v2.21, its a real no brainer in my opinion, but if anyone can give a really good reason as to why you should want 909 software on there instead of Cine 9, by all means, explain it to me. No one has put forward anything valid yet.

Testing time


See if options in menu's pop up when fancontroll gets plugged etc.
Tray of Cinemax, splitpack 919 and 4 trays of 919's.

Ok I tested Cinemax software version 2.13 with and without the Fancontroll in the tray.

With the Fancontroll you get the option Temperature that is not there without the board.
Bad luck made that the chip on my fancontroll board seems bad. I get -1C and once I2C error.

How about the noise. No difference in this setting but I remember having the tempsensor error before. I would not know as I seldom check the temperature but I would notice that the Max was noisy. Than I would check the temp and yes often a reboot fixed this. Often I had to wait a minute after shut down to fix the sensor. I will order some new sensor chips to continue this. Edit: might be some caps as later it worked again.

So I know from memory that the fancontroll board makes the Max more quiet. Not much but noticable. I could hear it direct from the start and after some time but I worked hard on getting the Max quiet with cork etc. So I listened closely.

Also the software is probable the same on the Seos and Max but the extra option only appears when the sensor is there.

Thanks for the schematics Hulio. (how do you always get that info)
When  i first time started to look at  controller boards (about a year ago) i had three of them all with different failures , but beside that all of them had a commun issue the core supplies +5vp and 3.3v had a excessive ripple (noise) one around 8%.
For a processor board it should be around 1% for reliable operation .
Same boards drew 0,8A others 1,3A the last where of course the worst regarding ripple, so i found out that the differents in current came from the different brand of the seven rams used by the altera chip.
Does your board uses the K6R4016V1 (samsung) ram's then the  current wil be around 1.3A, if you're board uses the AS7C34098 (alliance) ram's then the current wil be around 0,8A and that's a big differents
also for the +9v power supply it also lowers the heat up of the altera and rams. (maybe there are boardsbwith other brand rams ,i don't know of ?)  I did the test with one of the boards to know sure and replaced all seven rams and then the current was down to 0,8A. (don't want to do that again)
That was a big step in lowering the ripple of the supply but  i was not at 1% yet ,i had to replace the cap at I67 (3,3v) it was dried out , then aded a cap on  I68 (+5vp) because there was no cap there and there should be one , this can cause oscillations and there is no suppression of the ripple coming from I67 (new schematics confirms this) . Now the output at the suplies was at spec but was still out on the altera chip ,adding caps to the +3.3v on the altera did the job. Suppose this is the  pcb design at fault .
So the altera is from all the core components the one that 's makes the most noise.
My latest board is late revision and these problems seem to be solved (new schematic)
This is  only a discription of wat i experienced with the supplies on some boards.
Until now i managed to repair three board out of four ,the latest is a real challenge for me. (no clue yet,)
