Problems with CC3D

[Remorc]

Good afternoon folks!

I am having issues on my first build with my CC3D. I ordered the CC3D from ReadyMade RC since they are local to me and I have been having issues getting it to connect to my computer. I have disconnected everything from the FC with only the USB cable connected. When I connect it to the GCS, the green and blue LED light up. After about 5 seconds, the blue LED begins to blink. However, GCS never sees the FC and my computer cannot see the USB device. I have tried several computers (one Mac and one PC) to no avail. Unfortunately, I only have 1 cable that will fit this connection. Any thoughts on how to solve this problem? Thanks!

I just wanted to give an update. I contacted RMRC and they are willing to send me a replacement board. However, I bought a new cable today and everything works fine. This was my own fault. Just wanted to let everyone know. Party on!

Some USB cables are designed to only charge something like a phone, and do no include any of the data leads! Those can really be a pain because you see the thing has power! So what could be wrong? That had me going with my first APM controller. I found a short cable in the drawer and figure, hey I'd install it on my quad so that I didn't have to leave the USB connection of the controller accessible, just the end of the "extension". It was a charging cable!

I remember a major variable speed drive company selling me a $75 cable (nowdays~ $200) with 24 pin terminations to deliver data to a pc . Checked the pin outs & found only 2 wires connected end to end We made our own cables after that for about $10 Same BS is carrying on expensive HDMI cables which are no better than the cheapest physically good units

A long time ago, I worked at a specialty/tech shop and I learned to diagnose RS232. The hardest connections were to plotters, because if you got the handshaking wrong, the tx end didn't get the signal to pause transmission when the rx buffer filled, but it took a print file with lots of short vectors, and a bit of time to know if that happened. I'd watch the breakout box and the printing to see when tx stopped or the pen just went off like crazy. Some were hardware and some were software handshake, so just the pins didn't tell you. And the documentation was usually wrong, sort of like this hobby now. Anyway, we'd add a couple of resistors and maybe a cap to inert pins, then potted the connections before putting the covers on. People were happy to pay a premium for a cable no one else could or did figure out.
It's not the soldering you're paying for. It's knowing what to solder where (and the cost of the time required to learn it)!
