I cannot find a replacement cable for a APC power supply. I was wondering if there was a shop in Bangkok that sold unusual cables? Or, if I had the pinout schematic, if there a shop that could make it easily?

Online (non-Thai) parts suppliers want between 50-100% of the cost of the UPS for just the cable!

The RJ45 is standard Ethernet? I'd be surprised if it wasn't. If so I wouldn't think this cable would be too hard to find/expensive anywhere.

Are you in BKK? Have you looked around Panthip, Fortune etc?

eBay?

It's a USB to RJ45 cable (I have an APC also). Might be able to find it in the above posters mentioned locations, though suspect it is a special pinout.

No, I am not in BKK, but will be going there in a few days, and was hoping for some shop names at Pantip, wherever. Hopefully, I'll find something in the hour or so I have to finish this.

I got the pinout diagram at the same place you linked, Tywais. Good resource. It is actually an RJ50, but the pinouts.ru page specifically says that "The jack in the UPS may easily use a 8 pin RJ45 connector."

Thanks to both of you.

I took a closer look at the pinouts and APC deliberately uses pins 1 and 10 (which don't exist for the RJ45 but do for RJ50). I made a cable with an RJ45, but it didn't work. So I spent two hours scouring Pantip for a 10-pin RJ50 and not an 8-pin RJ45, and scored one in a bin of throwaway circuit boards (RJ50s are impossible to find). I made another cable, and it seems to work, but that's probably a false sense of security. I suspect that APC uses this unusual cable (rather than USB to USB), to keep guys from DIY their products and using below-quality cables. Time will tell.

Thanks, all.

So it is. I made an assumption (always a bad idea) that it was RJ45 since I deal with that regularly and am used to it. But yeah, just pulled mine off and RJ50 it is. Plus the pinout site says it also. Sorry about that.
