BARCO RCVDS 400 Quad RGBhv card?

[JMDickson]

I have been using a Barco RCVDS 400 Quad with a Data 800 projector. I have two Video/Audio boards, two TTL input boards and four RGB/S boards. I would like to feed the unit a VGA signal. Is there an RGB board the supports seperate sync for the 400? I have found a seller who has such a board for the 800, but I don't know if I can use that or not.
If anyone has any experience with this type of setup, I would appreciate the help.

hi you can mix the two signals H&V (Sh &Sv) of your VGA so you will have a Synchro composite. Sc.

you have interface VGAuniversal barco who's can do it , extron, conex, inline etc...

I understand the unit expects negavitve sync for both horizontal and vertical. Is this correct? I take it I should use a BNC-T connector to combine the H&V lines.
I have seen utilities that allow you to 'force' the polarity of the sync. Is the unit in any danger if it recieves the wrong polarity sync signal that may be sent during the PC's boot cycle?

you can't use the 800 board in a 400 switcher they are different.
As in the previous post combine the syncs with a BNC T piece.
