Tested without the little sub-board, same behavior, same message. I think that this sub-board is normal, as I79 is missing on the Index 2 controller, then present on the Index 3 one. So they likely corrected an issue and added the 74AC74 that way before implementing it properly on the controller board. (I have the index 0, index 1, index 3 schematics but not the index 2) Index 3 : So, I tested in my Data 808S, firmware 7.41, with an index 3 controller, no luck. Both SEMU aren't detected at all. Being RWI 5.09 or 5.10. Aren't they compatible with the Barco Data and needing a Barco Graphics ? If I put an IRIS board, even after the SEMU, the IRIS is well detected. km987654, do you still have your SEMU setup ? In case you can look at what PCB ID you have, in the menu ? Robin Hi Robin The SEMU won't show up in the Menu if you use earlier firmware than 7.61. I can only tell you that I have, right now, the same physical setup you have minus the interesting controller and the SEMU is recognised and shows up in the menu and you can operate the menu items. So perhaps there is an issue with that SEMU board or, as mentioned, your controller is different somehow. Do you have another suitable controller without the daughter board? and can you test the SEMU in another Barco (909 if available)? Just noticed an earlier image of a bunch of controllers and you have a suitable controller without the daughter board so try that one.

I had RWI 5.06 mounted, I switched to 5.09 then 5.10 unfortunately with same result... Running the set with the new SEMU in place, and video cables going to it disconnected, the message is the same in the menu (I switch the 720 input board with another one that has the "no SEMU" straps in place)
I will test it in the other 808, that has an apparently index 3 controller. Robin Okay get rid of that little daughter board "780805" the SEMU should go straight into the controller. If that doesn't work then its likely that your controller board has a problem or at least is not standard.

Hello, I got the newer SEMU-II from Hulio, and here is what I get : The only thing that the manual says about this is "Contact your Barco Service Center"... My older SEMU is PCB v3 : Having the last BG808S firmware 7.61, I don't think there is something possible to do... Robin What RWI version are you using. I have tried a few but only 5.09 works. I would say though that I have not seen that message at any time as it either worked or did not. Try just the SEMU-II board with no connection to the driver board. Could you post a picture of the controller with the SEMU board in place. A clear image if you could.

The SEMU board you have is very noisy. The SEMU board from the 909 works well with no noise in the picture. You will also need the contrast modulation board to make this work and the one that is designed for the 808s also creates much picture noise but again the contrast modulation from the 909 works and doesn't introduce noise. The contrast Modulation board will cut image contrast by a good margin making the image dull. If you intend to blend the best solution may well be an external blend box like a Diventix by Analog Way. Just wanted to add some information to my above comment about Contrast Modulation Board and how it reduces contrast by a good margin. Its been a while since I have used the CM board and after making the above comment I decided to take another look at it and its impact on the image. While there is a change in the contrast level I would say its not big as I first mentioned and I think this is because when I first installed the CM board the other boards contained 20 year old capacitors, I have over time replaced a significant number of capacitors right across the projector and this makes the projector different to when I originally tested the CM board.

Hello, Okay, so they are indeed different board and different version of the SEMU II. That's clear so. Have you tried to get the 909 version on a 808S ? I've tried to add the J20 with 74AC32 and 74AC74, with the stock controller, but no luck so far. The PJ start up, show the hourglass (as when SEMU is loading or redoing the edge calculation), then black picture. Whatever the remote button I push on, It shows the hourglass for some seconds and then black. So no menu, no way to switch to an input. (Except standby button which do its job.) That's a fail ! Using RWI v5.09 , that's not better. To be continued... Robin Yes I have added both the 909 SEMU and CM boards to a 808s Controller and they work just fine. You need firmware v 7.61 and RWI 5.09 and a controller that already has J20.

Attached are the two sets of boards. The one with the fan attached is from the 808. These boards create a lot of picture noise. The other image is of the 909 boards. Much better to use. 909 board numbers (clean)

I just don't understand why people keep dealing with him. There are far too many bad experiences including my own and a lot of these are available in open forums for people to read.

No, my tubes are still sitting on the shelf untouched... Using glycerol-water mixture seems to be a good overall solution, since it does not seem too aggressive either. You can buy ice clear with and without the anti corrosion agent, i cant remember which one Keith and i have, but he will have a bottle there handy. Ive never had an issue with it so far, but i didnt find any noticable improvement over poly glycol either. I have mixed ice clear with the poly glycol and it did go cloudy as shit to start with, but cleared up after about an hour or so, and with convection while in use, any cloudy fluid went away pretty quick. Just had a look at the bottle. It says Non Corrosive.

Well, i think i made a mistake here. After using my Marquees a fair amount in the last months, i noticed halos on black background around bright menus. Looking into the lenses confirmes: the glycol is cloudy again. Shame on me for telling you it was good. Now looking for a vendor of "ice clear AF" (or similar) in Germany. Are there any threads about coolants i did miss? Ice clear AF
All about Glycol CRT coolant and where to buy
Barco 808LC Glycol Replacement
Ice clear product page
Experiments with glycols and similar stuffThe refractive index of PMMA (=acrylic) is 1,492, monoethyleneglycol's 1,4318, glycerine's 1,4745. I do not know if c-elements are made of PMMA, that's a guess. One could also tend to use propyleneglycol, but according to Wikipedia, it is highly hydrophilic. I donot know if water would diffuse through the bellows and into the propylene glycol, but in the case of monoethyleneglycol, it does. If anyone does have the possibility of using a refractometer with a C-element, i'd be thankful. Regards, Julian Look Here for some Ice Clear information www.curtpalme.com/forum/viewtopic.php?t=37673&highlight=glycolOn reading that thread I see you have already been there

You need firmware 7.61 and RWI 5.09

How is this project moving? or not?

Thanks for the info. The 7.61 firmware turns the BG808s into a BG808s2 whatever that is. I have never seen the RWI 6.3 my latest is 5.10. Okay I had the version wrong, but here it is. It's 6.01. Keep in mind, this did not work or did not work optimally with old remotes. I am not sure if it didn't work at all or if it only worked with the rear reciever. Yes you are right about the remote. The Cine series used a different system to the rest of the Barco CRT projectors. Well the 8 and 9 series not sure about the 7. Thanks for posting firmware.

RWI I think was 6.3. Latest version I believe. Oddly enough on the 808s using this version turns the old style remote completely useless, so I only have that in my Onyx. The ctrl needs a 1 mbyte eprom, originally 27c801. Same size as the last version 808 you uploaded (hence I will also need to get at least one of those eproms though I might have a few out in my workshop, will see). Thanks for the info. The 7.61 firmware turns the BG808s into a BG808s2 whatever that is. I have never seen the RWI 6.3 my latest is 5.10.

Casey is the Gun when it comes to Barco ASTIG. He has spent more time learning about these than most have spent watching movies. I think from memory he put together a procedure and posted it on here. I would say that the same procedure he uses for the Cine 9 would work well with the Cine 8. You can spend a full day on one tube alone to get the best corner to corner focus. Getting CPC setup correctly is a lot of time but it makes all the difference. Its time well spent.
