Is there a multipin cable rated for cat-5 type use?
(Most of the lines are for baluns but few are data)

Need an easy disconnect for 14 cat-5 for an A/V equiped lectern. Is there a multipin cable rated for cat-5 type use? (Most of the lines are for baluns but few are data) |
14 Cat5? Let me guess, is this for NASA?

3 lines for rs-232 and I-R
1 line for building network connection
1 line for e-snake type networked audio
1 line for touch panel controller
I'm just following the blueprints but would have done things much differently myself.
(I could probably get the control lines down to one, would have used a local switcher so only one video output and then everything would fit on one of those wireworks connectors mentioned above.)
Thanks for the tips!

I know when done properly there is less than 5/8 of untwisted pairs between in and out with the modular style connections. I don't see how this is possible with circular multipins? Likewise the physical spacing between the pairs is much wider and not in a linear fashion like the modular connectors. All the category spec's have been designed and based around the 8p8c connector -how will deviating from that effect the transmission? I am curious how the wireworks connector fares -and how much deviation from spec is there and if there's enough headroom left for other deviations in the system such as excessive footage of stranded patchcords, 8p8c "barrel" type joiners and/or patchbays inline? Nor have I ever seen soldered connectors in telecom but that would be a necessity with some of these connectors.
(It seems I have too many questions -and first time in my audio system design career I'm feeling way overwhelmed with our industry's shift to data technology!)

yup, very few (if any) non RJ45 connectors will meet CAT5 specs, but since a lot of what AV uses CAT5 for isn't as picky, other connectors will work.
if you're not running ethernet over the cables, chances are pretty good that you'll be ok.
