I would like to use my older Moome cards in my switcher. Could anybody please tell me what the proper modifications are to make these work!

Thanks

I will answer my own question. After much work I have found out how to mod these cards to work in the Ehome switcher. I have modified a DVI card from 2005 and a hdmi card with gamma from 2007. They both work in the projector and in the switcher with this mod. The newest Moome cards have this already and are the best cards Moome has made yet! I recommend that you buy one while you still can. I just wanted to be able to make use of the older cards and if you need a component input the older ones have it! I like the cards with gamma adjustment much better than the ones without it.

Top of card:
Cut c15 flush with circuit board and also 1/8” from the back of the connector.
Solder wires from c4 and c26 to the 1/8” nub on c15.
Bottom of card:
Form a solder bridge on abc4.
Solder a wire from any pin on row 27 to pin a16.
Disconnect a15 from 5 volt supply:
The 5 volt trace runs under the 32 pin three row connector from abc5 to abc27 with a short trace to abc15(top of the board). The short trace to abc15 needs to be cut. This is hard due to lack of space but it can be done! I suppose you could drill from the bottom to remove the trace also. I would use a very small drill bit, less than 1/16” and use your fingers to drill the hole.
I used a very small Jewelers screwdriver to scrape across until the trace was broken. You need a very powerful magnifying glass to see what you are doing. Do a continuity check to make sure you have cut the trace. For the continuity check attach meter from any pin 5 to b15
Pin numbers:
With the card right side up and the face of the card pointing at you the pins are as follows:
A) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32
B) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32
C) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

Don't try this unless you have the skill to pull it off!
Good Luck
Gerry
Very Happy
