There probably is a device that measure resistance of multi-conductor ribbon cable, but it is also probably custom made and costs lots of money.I know the circuit that Seldons sent to me; it is controlled LED on and OFF.
It is not my question that I am trying to ask. My question is, if I have
40-pin Ribbon cable and both side of cable has 40-pin connector. In
order to ohm out for continuty between 2 sides, I can use Fluke meter to check it, but it takes too long to do it every pin.
If someone knows, is there any electronic device tester or circuitry to perform continuty check with thousands of Ribbon cables in production?
great ! One question tho' Setting connectors up in that manner makes the ribbon one long wire... How do you judge which wire is open if no continuity...??Take a couple of sockets and wire so that all wires will be in series when the cable is plugged in. Battery, LED and resistor will show continuity. Then, take another connector and tie all the odd pins together and all the even pins together. With one end of the cable plugged in, the bussed pins should still show an open condition. DONE!
Sorry for the delay. I've been withoutout internet service for a few days.great ! One question tho' Setting connectors up in that manner makes the ribbon one long wire... How do you judge which wire is open if no continuity...??
