Any cat5 cable I've ever seen has 4 twisted pairs on this side of the pond. This place has about 400 feet of cat5 strung about and its all just 100mbit. I think the router I bought last summer can do a gigabit but I don't believe either side of it is running that fast. I did find some crimp on 6 wire plugs at the shack last night, and some 25 foot wall to phone cables but the only females were either in the usual 2" square boxes or in line couplings, half of which were still too big if they had been pried apart. So I settled on a 5 way inline with setscrews to retain the wires. A lot easier to breadboard for testing too. Later last night I fine tuned the .brd file a bit, finally figuring out how adjust a hole so it didn't snap to the grid which because of that parts foot print I had to set to 0.05 inches. But when I tried to run pcbgcode --config I think it was, I got a missing drill.cfg (or something similar) so when I am awake next, I'll need to read up on that. What I did read seems to indicate all drill holes are in the same file regardless of size, and there is only one 'layer' for unplated holes. I would have thought it would put each size of drill in its own layer so that one could mount a given size drill, and run the output file for that size of drill. Probably something I don't understand yet. The only real problem I had with the board layout is that I had to repeatedly ripup the individual nets by hand, all of them, before the auto function would even try to fix things when I moved parts to actually fit the board real estate I can use. Seems to me if there is a Drc error, it should do an auto-ripup and start all over, but I didn't find that magic twanger to do that. But I got it done, so its not a show stopper by any means. > ------------------------------------------------------------------------ > ------ Try before you buy = See our experts in action! > The most comprehensive online learning library for Microsoft developers > is just $99.99!
