Programming cable specifically for S-Drive controllers

[jk-tech]

Hello,
i looking for the software so long and don’t found it anywhere. Can anybody give me a tip?
I have some pg controllers because i try to build an offroad mobility scooter for my wife. Unfortunately the wigwag poti don’t live long because of heavy shaking. I want find another solution of the expensive poti.
Many thanks

I don't know if it would work for this, but my first thought would be to use an Arduino or other micro-controller to drive a 'digipot' for the input to the controller (see discussions elsewhere for the Arduino based RC system for a more detailed description...) and then finding a more suitable thing to use as a user-interface to feed the Arduino...

This is short on details, but might give you a way to get started...

Finally today I did it successfully. The issue was the damn CH340 chip, infact today as I received the FTDI232 I connect it with the same previous wiring setup and it worked like a charm.

So thank you all guys for your time, especially @woodygb, I really appreciate it!

Dear all,
i got the sofwtare, thankjs a lot.

@ ex-Goosereider
i did your idea for a hacked cheap china controller (PWM DC10-55V 60A). Analog input from a standard robust poti, reading it constantily and convert it to an pwm signal, feeding a low pass filter to generate a anlog output from 0 to 5V. It works, but the electronic conversions was to extensive so i looking for another solution.

Then i use an curtis 1225, this controller have the abiloty to modify the sensitive of anlog input. So you can install an robust poti (in use https://docs.rs-online.com/56b9/0900766b81584534.pdf), set the parameter to 15 instead of 100 and so you can use a 285° poti as an 20° poti. This works great, but not with PG Controller.

In case of PG controller it seems to be a current sensing system because the second ground speed poti is in serie with the wigwag and in this case only current measuring is avaible or anothe black magic measuring. Now i know that the ground speed is also avaible at a separate pin after controller programming. I hope i got 0V and 5V on the poti-pins to feed the mcu and drive the controller with analog output.


Many thanks

You do NOT need the second speed limiting pot... simply omit it.

Dear woodygb,
many thanks for the fast answer.

Unfortunately i need the second ground speed poti, because my wife drives sometimes very dynamical, also in the supermarket and second i want walk and not run alongside of my wife.

But i'm sure to find a solution.

A verbal request to "slow down" might also work.

[woodygb]

You do realise that there are 2 wiring options for the speed pot?

Check your P.M.

where can you find the software??

Hi,

I have a Kymco XLS with an s-drive. I need to find the software for modifying the programming along with the cable detailed in this topic.
I am a new member and need help.

Thanks

Hi Jonathan ...Welcome!

Please add your general location to your profile.

I can provide a lead ...but postage may be prohibitive depending on your location in this world.

Hi,

Profile updated.

Thanks for the offer of a cable, how much is it? I will probably try myself first , but if I fail I will be in touch for sure.

I will let you know how I got on with everything when done.

Thanks again

Jonathan

I can offer 2 versions ...one is based on a cheap chinese FTDI chip clone/knock off board @ £15 or one based on a GENUINE FTDI chip cable @ £25.

Hi all,

As promised, details of my investigations with a Kymco maxi xls.

To start with I tried a couple of usb - ttl adaptors I had kicking around , the first was a genuine pl2303. This did not work.
Next I tired a CH340, again I had this and use quite regularly for other purposes, again this did not work.

Today I received a ft232rl, from a uk seller, but probably fake, it worked- first time no problems.

I have seen some discussion in this thread regarding the pull up resistor value, I can confirm that 47K and 33K both worked fine and in fact I still had good comms with the 5v completely disconnected from the adaptor.

I used both the manufacture and oem software versions without any problems, and I was able to turn the annoying reverse buzzer off completely. Happy days.

Big thanks to woodygb for providing the software and manuals.

Jonathan
