Where can I find a listing of all the IFB cards that fit the sony projectors? Anyone got specs for them? I think it would be good info to have around.

Find a brochure for a G70 or G90- the latest models.. it should have them in the accessories section. For your 1272, all that's really useful is the IFB 11,12, and 12a. The 12 and 12a take component, but 480p only, unless you want green push. Others are S-video and 9 pin vga. There are ones(indexers) to designate a section of a screen, such as used in multiple RP cube setups, but no use for them.
With a switcher you could play with a IFB-3000 doubler.. harder to find.
Then of course there are the Moome Component/HDMI cards for sale if you have $$. The Crescendo transcoder+IFB-11/12+HDFury will do the same for less, though.

I just picked up a switcher today, it has an IFB12a in it. I thought I would be able to use it in a stack, and I see it has a bunch of jumpers and a few switches that I want to know about. Altogether I have three ifb-11's four ifb-1000's and one ifb-12a. Can I do the stack with an ifb-11 in each pj and an ifb-12a in one?

I am not sure quite yet of whether or not the IFB-12 will work as an OUT in the second input slot of the projector itself- still have to test that theory. It SHOULD however work as an out on the switcher. There is an in/out switch on the '12. not sure if there is anything else that needs changed on it yet, but it can't be set for component input obviously. Since you have the switcher, connect your inputs thru it, and send the signals to the projector using MONITOR OUT and the IFB-12.

There's a good thread in the archives (I think) about the switch settings on an IFB 12 to get it to accept 1080i, There is a sequence of jumper/switch settings that the IFB manual doesn't cover that get it to work with 1080i.
If someone finds it, maybe we can cut and paste it to the main site, as it is good info.

I've found this so far:

I finally got around to using Brian's switch and jumper settings on an IFB-12A. Unlike Brian, who installed the IFB-12A in the projector's "B" slot, I installed the IFB-12A into a PC-1271 switcher. The switcher is connected to my VPH-1271 projector via both a remote cable (SIC-M) as well as via RGB cables. As an initial test I connected by DVD player's 480p component output to the IFB-12A and sure enough it came up working when feeding the signal from the switcher to the projector via the remote cable (component video can only be sent from the switcher to the projector via the remote cable and not via the RGB cables). The picture looked good and will only require minor adjustments of height, width, etc. As a next step I'll give this setup a try with 720p and also with 1080i. The big advantage of using the IFB-12A, either in the projector's 'B" slot or in the switcher, is the projector's color intensity and hue actually work. Using a transcoder with my Panny RP-82 DVD player I found the color intensity somewhat too high with most movies. For the past 3 years I have been using the component input built into my other projector (G70) for my HD sources (currenly 4 sources of 1080i) and I have found that having full control over color intensity and hue is a significant benefit, especially when dealing with multiples source devices."

"This is a follow-up to my post of 10-11-04 above. This is with a IFB-12A installed in a PC-1271 switcher and connected to a VPH-1271 projector via a SIC-M remote cable. The IFB-12A has the switch and jumper settings that Brian came up with. I previously reported success with a 480p signal input. I have now connected a 1080i source (D-VHS) and can report that also works, but with a few comments. The projector/switcher was already being used for RGB inputs of both 480p and 1080i and as a result I did not need to adjust the projector's convergence settings when going a component input via the IFB-12A. However, I did find that I had to adjust: Size (image height and width), Position (to center the image), and Blanking. I did note a few things while making these settings for a 16X9 aspect ratio. I had to set the Height to minimum while and the position settings can cause some sync problems at certain setting. It is posible to get some 'foldover' within a cetain range of position setting (I have see this same effect with other projector's). However, I was able to find a combination and size and postion settings that worked OK for my setup. When all was finished I had a centered 16x9 image without any sync problems. I did note one odd thing and that is with a 1080i signal the Hue control doesn't function (get a 'not applicable' message on the screen), but with a 480p input the Hue control does work. However, the color intensity control does work with both types of component inputs.

Hi,
I've finally been able to test all that...
First lets have a look to the IFB-12 et 12A differences, here are the service-manual for those boards : (PDF de 2.5Mb each) IFB-12A et IFB-12 you will see that the différences are minimals and are not involved in our quest of 480p/576p/720p/1080i on 12xx CRTs.
I've just completed testing on a 1292 with both IFB-12 and IFB-12A both works like a charm.
But what a hell are doing those jumpers and switches ?
The schematic will give you the answers, pretty simple.
First JP5 (HD/GS) simply told the board we are hetting the sync signal from the Y(G) and not from H & V... So need some work before going further inside CRT. JP3 & 4 ("Sync"/"Vidéo") are obviously linked to this as they told the board to get the sync from the former treatment and not from H & V connectors.
No mystery here.
It's a bit more complicated for the from panel switches, but basically we told the CRT that the input signal is Component... Why we should put both switches 2 & 3 is not explained in the SM, but I guess it told the inside of CRT that the signal is not 15Khs (swhitch 2 alone) and its component sync (switch 3 alone)... Thanks brian for dicovering that settin both at same time do the trick on 12xx
Note that D50, G70 & G90 does manage this switches from the internal software and dont require the front panel stuff.
So, it does work wether it's an IFB-12 or 12A and it also work on the wonderfull 1292
Enjoy

Interesting indeed.. I never could get 1080i to work with my IFB-12.. have yet to try the 12a.. Maybe I should check back over my switch/jumper settings.... This info would be useful here on the site:
1. The settings for normal RGBHV input/output
2. The Component settings mentioned above.
