From: KJ on 13 Dec 2005 05:20 I own an Asus P4R800-VM and I would like to connect it to my TV set through the TV out. There is a TV-out connector onboard (6-1 pin, TV_OUT1) and I know there is a bracket/module for this (ASUS AV/S), but I do not want to use this (space and costs). I think it can't be that difficult to create my own, I do not see so much electronic parts on the module. It is just a matter of connecting cables. But I don't know the pin layout/meaning of the connector (it is not in the manual, all others connectors are) Does anybody know the meaning of the pins? There are 5 pins, I reckon there is 1 common ground, 1 composite signal en a couple for s-video/s-vhs (luminance (Y) & chrominance (C )) Pin1 from the connector is on the board & the manual topright) I saw that all/most Asus boards with tv-out have the same connector and probable the same pin layout. Mine is: _______ |* *|1 |* * *| ----- Does anybody know this? Or owns a ASUS AV/S module and could check this? I would help me a lot. Thx.

PDF page 38 of this new motherboard manual has a pinout: http://dlsvr03.asus.com/pub/ASUS/mb/socket939/A8N-VMCSM/e2294_a8n-vm_csm.pdf Post back whatever you discover, like whether the pin labels are correct or not. With the computer unplugged, it should be fairly easy to use an ohmmeter, and verify the two ground pins. Paul

I did find the two grounds pretty easy and those seem to be/are the same (the two on each side of the empty one). But now i found two 'readings' of the rest of the pins. One (yours) says oppsite to pin1 is the composite and the other says opposite to pin1 is one of the 2 s-video. But that would mean that there also are two AV/S modules, and that seems kind of strange, don't you think?

I think this is the AV/S (part number 90-C1OOBA-00XBY) http://www.newegg.com/Product/Showimage.asp?Mode=&Type=&Image=13-131-211-02.JPG%2C13-131-211-03.JPG&CurImage=13-131-211-03.JPG&Description= The only other reference to the pinout I can find, is this posting by Fred. The diagram in this post could be the cable end or it could be the header - in other words, a mirror image. http://groups.google.ca/group/alt.comp.periphs.mainboard.asus/msg/2caac55f603a589d I doubt they would use the exact same header pattern and change the pinout. That wouldn't be very bright. I don't know where else to look, to verify the pinout. And it is likely that all three active signals will be driven by the same kind of driver circuit. That is why I didn't offer any advice on sorting the other three signals... Paul

Because in his example the opposite to pin1 (gnd) is alway the composite, no matter how you look at it. The only mix up he could have made is the pin numbering i think. So pin6 = pin2 Would you have any idea if it could harm to just test it? I would first go for pin1 & pin2, being a composite signal. Test it on a TV screen. If it is not the composite but a s-video signal it will not hurt my tv, won't it? And the same for mixing up S-video with composite....
