I have been using 2 cables to test with. both 4-6 #1 6' #2 15' I boot box, plug in #1, both ends are detected. try #2, no ends. try #1, both ends. try #2, no ends seems like a bad cable. so I plug #2 into a dv cam, cam gets fw2, dv plays in kino just fine. un plug cam, plug back into laptop, no ends. back into cam, dv2. back into laptop,no ends. I have about 100 firewire cables, probably 10 the same as #2: 4-6, 15', same manufacture. I also have other boxes I could use to help figure out what is going on. But I am hesitant to start introducing more hardware without some guidence. any suggestions? -- Carl K |

Most DV devices are only S100 devices ( = support only 100 Mbit/s data rate), some rare ones are S200, some S400 ( = support 100, 200, and 400 Mbit/s). S100 is less demanding on cables; it is easily possible that a badly built cable works without a glitch at S100 but fails miserably at S400. -- Stefan Richter -=====-==-== ==-- =--== http://arcgraph.de/sr/ |
