Just bought a second 1272Q projector (only 745 hours!), thought if the first one ever gave out and I didn't have another one I might go through withdrawls or something. Anyway, it has an IFB-20 in it. All I could find for information was 1.)analog RGB input (D-sub 9-pin) 2.) RGB bandwidth of 120MHz. What can this be used for? I also got a SIC-20 which has a 9-pin on one end and (2) 15 pin on the other end (1 male 1 female). Is this good for anything??





Thanks! Ron

You can use that card just like a regular RGBHV card. With the cable you have, it's perfect for feeding an HTPC to the projector.

Good to see you again, Bruce.

Ron - if you don't want the cable, let me know - I have a couple of the IFB-20 cards, and my soldering skills are such that I was never able to fabricate a cable that would allow the card to work properly. (or - perhaps my card was defective. Even applying Occam's razor, hard to tell which is the case, so I gave up, even after some detailed and patient help.)

It seems that there has been a couple of different wiring schemes for 9pin to 15pin VGA cables. You need to check that the cable is the right one for the Sony IFB cards.

If I can recall, I think that the Extron 9pin to 15pin cables were different from the Sony diagram......or it could be another, I'm just not sure. However, if making a cable, just make sure you use a Sony diagram. :)

Yes, I believe Extron uses "unique" pinouts on its D9 and D15 connectors.

I'm not even sure if either Sony or Extron complied with the VESA pinout standard for EGA to VGA adapters. :confused:

However, I just use the pinouts for the equipment it's going to be used on and never have any problems. ;)

Sure - but you have an unfair advantage. You can see all the small stuff, and solder it correctly. ;) I could have about 20 years ago, but it has become a pretty iffy proposition in the last few years. I'm pretty sure I used the Sony charts you so generously supplied me with, but somehow I made a hash of it. Now that you've reminded me, I may give it another try, just to say I've done it. :o

:p :D :p lol. See all the small stuff? Why would you say that? I work through a desktop magnifier light......and I still have to use my reading glasses. :)
