Edgeflyer Posted July 5 Share Posted July 5 A long shot but I'm hoping someone may have a Tarot ZYXS2 that is no longer needed. I have one that I need to reprogram and can't find a usb cable or Bluetooth connection module for it anywhere to buy. I only really need the programming cable for. PC or mobile app but I can buy the gyro as well if necessary. Quote Link to comment Share on other sites More sharing options...

Edgeflyer Posted July 6 Author Share Posted July 6 That's great thanks but I'm not receiving from bmfa for some reason. Can you message me here? Quote Link to comment Share on other sites More sharing options...
FlyinFlynn Posted July 6 Share Posted July 6 That looks for all the world like a standard USB-Serial adapter Maybe try something like this. Quote Link to comment Share on other sites More sharing options...
Edgeflyer Posted July 6 Author Share Posted July 6 It does! I have a standard adapter but not sure of the pinouts got the ZYXS2 data port. Quote Link to comment Share on other sites More sharing options...
FlyinFlynn Posted July 7 Share Posted July 7 As to the pinouts, the ground pin in the data port will be connected to the ground of any servo socket, the +ve may also be connected to the +ve of the servo output...but it might not be as the servo will be +5v and the programmer may be 3v3. As to the Tx and Rx it wont hurt if you get those backwards, it just wont work so then try swapping them over. Other than that you could open the ZZYXS2 case and have a gander, the Rx and Tx traces will normally go together to a uP of some sort whereas the +ve will go off by itself.

FlyinFlynn Posted July 7 Share Posted July 7 Just found this - Can someone please help me with reprogramming a Tarot ZYXS2? It's the yellow version and does not have a usb cable as it came on a 2nd hand Heli. I bought a Bluetooth module for it as I thought but it turns out to be the ZYX 24 whereas the module for the ZYXS2 is the ZYX 12 I think. Itlinks to BT but no response from the gyro. If I knew the data port pinouts of the S2could I use a standard usb dongle to connect? The data port is 4 pin and I've worked out the first 2 pins from the left are ground then +5v. The other 2 presumably tx and Rx? I have a ft232rl and could make a lead. Will this work? Any other ideas please? on https://www.rcgroups.com/forums/showthread.php?1512179-New-Tarot-ZYX-ZYX-S-ZYX-S2-Flybarless-System/page851#post52678671 Quote Link to comment Share on other sites More sharing options...
Edgeflyer Posted July 7 Author Share Posted July 7 Yes that's me. Thanks for your suggestion which I may pursue as I have deduced the +5v and ground pins and can try swapping tx and Rx. As it happens Martin has kindly offered a zyxs unit for which my Bluetooth may work and which has a usb lead that may work on the S2! Many thanks to all for the assistance.
