v9980 vid card how do i get tv and security camera signals into card?
hi there
like i said i have the V9980 ultra vid card and want too put my cable tv, and my security camera signals into it so i can watch tv and monitor the security cameras. i the security cameras are going to a multiplexer and video recorder so i have several outputs. But where do they go into the vid card? cable tv just goes too the tv. |

But where do they go into the vid card? cable tv just goes too the tv. The Asus product information is sorely lacking. If I were you, I'd start by checking the software interface for the video card. Does it offer the option for more than one video input ? My expectation is, the hardware can only digitize one video input at a time, and the video breakout box on the product may in fact, only support one video source at a time (i.e. you may not be able to plug more than one video input device into the breakout box at the same time.) The card appears to use an "Asus AV adapter", and I think this is the same one as depicted on page 9 of http://www.asus.com.tw/pub/ASUS/vga/...1145_v8460.pdf (3.7MB) Treat the rest of this post as speculation --- This is a breakout box, with four connectors on the front and a cable with 9 pins that plugs into the video card. I have no info at all on the 9 pin possible pinout (the connector on the video card). On the front of the breakout box, the connectors are S-VIN In Composite S-VID Out Composite (DIN Input (RCA (DIN Output (RCA connector) connector) connector) connector) ___ ___ x x x / \ x x / \ x x x x | x | x x | x | \___/ \___/ [ ] [ ] The picture at the very bottom of this page, shows a possible pinout. http://www.weethet.nl/english/video_connect_pc2tv.php ___ ___ Cr - Lu / \ Cr Lu / \ G C G G | x | G G | x | \___/ \___/ [ ] [ ] There are a couple of video standards involved here. The leftmost connector actually has two interfaces on it, the four pin S-VID interface (Ground,Cr,Lu,Ground) and the two pin composite interface (Composite,Ground). There is the higher quality S-VID standard, and there is the older composite (baseband) video. The S-VID has separate Chrominance (color) and Luminance (intensity). Apparently, it is possible to connect a composite video signal, to the Chrominance by itself, and still get the signal to work. Based on that observation, the breakout box could have the Cr (Chronminance), the C (composite), and the center pin of the RCA connector, connected together. That is why, you should use only one video input, unless there is some evidence in the control panel for the Asus software, that the inputs are truly separate. If you own a multimeter, you might do some investigation that way, to determine how the breakout box is wired. The pinout of the left connector is not, as far as I can find with a search engine, standardized. The outside four pins are standard, but the three in the center are not. For example, I have a 7 pin to composite _output_ adapter that I got with an ATI video card, and the composite output signal is actually on the pin labelled "-" above. I have a separate adapter plug I bought at a TV/stereo store, and it converts S-VID to composite. With an ohmmeter, I can see how the Cr pin on the DIN on the left above, gets connected to the center pin of the RCA connector. So, to start with, have a look at the software and see if the software interface offers any info about the capabilities of the breakout box. My expectation is, at best the breakout box offers multiplexing only, and at worst it offers only one input and one output device connected at a time. In any case, I don't expect you'll be simultaneously looking at the security cameras and the cable television at the same time - unless you purchase a separate TV/video digitizer card to simultaneously digitize a second signal.
