Help Needed: Troubleshooting 2707-NC5 Allen Bradley Cable Connections

Question:

Hello, I'm in need of assistance. I'm looking for someone who has a 2707-NC5 cable and is willing to help me by opening the case to inspect the cable connections inside. I have tried referencing a pinout diagram from a manual, but it hasn't been entirely helpful. I have identified two broken connections that I need to solder back on correctly. Specifically, I'm concerned about the black and white cables that are currently soldered on, but I suspect they may be reversed. These cables are highlighted in the attached picture. I plan to send the cable out for on-site testing, so it's crucial that the connections are correct. Thank you for your help.

I'm having trouble locating the specific cable I need, despite searching through my collection of old cables. It may be a 422 to 232 cable. I will continue my search until I find it.

I'm currently searching for a hard-to-find cable, specifically a 422 to 232 adapter. Despite checking my old cables, I haven't been able to locate it yet. I will continue my search and appreciate the effort put into helping me find it.

Here is some information that may be beneficial to you.

Hey there, it sounds like you have quite the situation on your hands. I regret to inform you, I don't own a 2707-NC5 cable currently to physically help you out, but I've had a similar experience a while back. A solid piece of advice I can lend, in addition to studying the pinout diagram, is always to document your original configuration before changes, that way you have a baseline to revert to should things go awry. Concerning the black and white wires, typically, black indicates ground and white is usually for data, but, of course, this will vary based on the manufacturer. I agree with your plan of on-site testing after doing the fixes - there's nothing like testing to assure things are in proper working order!

Hey there! I actually have the same 2707-NC5 cable you're talking about. I'm by no means an expert, but I'll gladly open the case to help you out. From my understanding, the black wire typically denotes ground while the white wire is often a neutral or data line in these setups. So, if your suspicion about the reversed cables is correct, you may run into performance issues or even potential damage. Please wait for my confirmation by sharing the internal setup of my cable! Would also recommend checking with a professional or the manufacturer just to be totally safe.

Hello there, I'm familiar with the 2707-NC5 cable. Your caution about the potentially reversed black and white wires is indeed in orderβ€”the negative ground or signal ground is usually black while the white can be either a data line or DC power. However, it can change depending on the person who wired it previously. I suggest, if you're uncertain, try using a continuity tester or multimeter to trace the path from the pin to the wire in question. This way you'll be assured you're soldering them back correctly. Good luck with your repairs!

Hey there! I'm fairly familiar with the 2707-NC5 cable and would be happy to assist. From the picture and information you've given, it indeed sounds plausible that the black and white cables could be reversed. The black cable typically signifies the negative or ground connection, and the white one for positive. However, to be utterly certain before you proceed, I would suggest double-checking with a multimeter to be really sure before making your final solder connections. Let me know how it goes or if you need more assistance. Best of luck with the troubleshooting!
