Is this one appropriate. https://www.amazon.com/USB-TTL-232-converter-serial/dp/B01CNW061U/ref=mp_s_a_1_6?ie=UTF8&qid=1534116404&sr=8-6&pi=AC_SX236_SY340_QL65&keywords=usb+to+ttl+232 I believe I have an infineon cable purchased about 5 yrs ago but it may be like looking for a needle in a...

Im ordering these for the next part of this project.

I guess I put the cursor in the wrong place to measure shortest pulse. Looking at the divisions it seems like 10us. I will order an rs 232 serial to usb adapter as I cant seem to find the old one I had lying around.

I will look at the post for more info. I was able to capture a decent image of the communication. The four wires are red black green and yellow. Going on the assumption the green and yellow were comm wires was wrong. After more experimentaion it seems that there is 5v, ground, pack voltage and a...

Great advice everyone. I will wipe the dust off my usb osciliscope and capture the output as a first step and post pics here.

As a personal challenge more than nessesity I want to try creating an arduino software to communicate with this controller. I have a friend who owns a working complete scooter. I can connect to intercept data signal. What device could forum members recomend to record serial data stream. Reverse...

I have programed kelly controllers but its been a few years. My memory is that the com port selection is important and definitely the controller needs to be powered. I cant remember if key on must be connected too but try that if you havent already.

I use two giant zipties and a sadle shaped piece of rubber to mount to any tube. Removable and much more firm attachment than stock bracket system.

The 4 wire set definitely includes pack voltage so with only two remaining pins it is hard to imagine how the headlight, throttle and brake switch opperate. The pictures are from an alibaba page selling the top side board Link to ad...

Pictures below. The controller looks more modern than I am accustomed to seeing.

Looks lke I cant post pics yet as a new user. I will post pics when that feature is unlocked.

I found an abandoned, vandalized scooter in the gutter no battery or handlebars. It appears to be very new technology compared to other ebikes. I connected a 36v power source to the controller. The wire harness that leads up to the throttle and on off panel has 4 wires, one of which is pack...
