New member,
                Looking for the cable and software that will let me modify the settings in a Curtis 1228-2412 fitted to a pride mobility scooter.

                Most of the links are out of date for cables.

Thanks
Jeff

In the end I was successful by using an Arduino UNO R3 board as the USB-TTL converter and a 4001 IC (2 XOR gates) to invert the in/outs.

If anybody's interested in the wiring details for the Arduino/4001 solution, let me know.

Dave

Hi Dave, i´m very interested. Can I have the details? Thanks

great work I have been given a Curtis 1219 controller and want to have a mess about with it my question is if I build this adapter would it work on the 1219 controller? Many thanks for any info or tips on building the adapter

Im not sure it would work. I think the 1219s were built in 1999 ish so would be predating that software and quite old now

Hi, I am a new followers at this group

Could any body help me to get the 1314 PC Downloader for using with Curtis Control 1230 ??

I need the PC Software for programing the controller

At the last topic, I found the link from 'ampman', but I can't change the file into .exe

If you look at the post from Dima, near end of page 1 of this thread, there is a link to a newer version of the software online. Use the username / password he has given

Still the car looks nice, just don't spend too much on it as those type can be more expense to get running than say getting a newer Lithium brushless small car



We are having some problem to troubleshoot the Curtis motor controller
Problem is how can we Identify whether the motor controller is defective , when taking the parameters mode select value is one whether the system is on or off . Value can't be able to change.
Other parameters are able to change .
Is it the problem due to hardware problem.motor is not working please find solutions

Hai
I have problem to be solved immediately regarding the Curtis motor controller
How can reprogram the motor controller.
I could collect current parameters using programmer .I have edited the parameters and burnt but parameters of MODE cannot be changed as 1 . Whether the carriall is on or off.
Is it any hardware fault

Any body Please help

Just wanted to say thanks for all the good stuff [smile]

I'm trying to convert a mobility scooter (bought for parts) into a ride-on city bus for my kid.  Turns out the controller is throwing an error.  So, I was looking for diagnostic codes, found the full service manual with codes, and now I have the software (and interface schematic) to re-program the thing if it comes down to it.

I love the internet [thumb]

Hello

I want to realize die programming cable adapter for the curtis controller with the arduro board. Can anybody helb me with wiring diagrams and the programm for the arduro. That would really help me.

One more question.
I have a problem with the undervoltage limitation of the curtis. 68% of the voltage are still too much and I would like to adjust even less. Less than 68% can not be adjusted.
Is it possible to program the Curtis with 36V operating voltage but to operate it with 48V so that I can discharge the batteries deeper?

Thanks in advance for your help

Great. Out of interest what error was the controller showing and could you fix it?

I don't know about that, but generally the level is set to prevent damage to the batteries which happens if they go too low. One way round this is to have a bigger battery bank in Amphrs and then there will be less voltage drop and the cut out triggered less. What power is your motor and how big is the battery?

Near as I can tell, it's a 3-1, or throttle wiring.  All the wiring checks out, so the project just got bigger.  Time to have a conversation with the controller itself. 

I will, when I have time, build myself an opto-isolated serial cable that reverses the logic levels... should not be hard.  I'll just dead-bug the wiring to a DIP and pot the thing in hot glue.  Then, I'll attempt to get the programming software up and running on a laptop.  The first target will be a very old ThinkPad, running Win98, that has an actual serial port.  Failing that, I've got an XP laptop that I can try using a usb-serial adaptor.  No shortage of old junk I can waste time trying to make work.

Hopefully, once I can talk to the controller, I'll figure out what exactly is wrong.  Theoretically, I should not need to reprogram anything but, seeing as how I have to make the connection, I might make an attempt at replacing the rocker throttle with some console racing pedals I have.  Might be easier than the original plan of setting up a mechanical linkage from pedals to rocker.

Lots of fun... just annoying that it's gone from a quick to more involved project.  Lots of other things to do too.  I'd rather be spending my time making steering knuckles on the lathe than fighting with Win98 etc..

Haha!
Sounds interesting but don't envy you doing those tasks lol. Keep us updated.
Which model number of controller is it? I'm not sure which Curtis controllers actually work with that software

Hi guys, nice project here.

The way to buid a proper cable is have an usb-serial ttl converter and invert the rx and txd wires.
Or use a max232 chip to make ttl signals form the good old derial port on your PC.

I made my cabe using a 7404 hex inverter, it turned out Curtis used a hex inverting schmitt trigger 7414, but the 7404 worked fine.

I never had the cance to look at an original interface, I just bluit my own afted measuring signals form the programming/display port.

The way to go these days is programming a FT232RL chip. You can program these to invert rx and txd lines. If you program the right VID and PID you can even use it with the latest software.

Buggies gone wild forum has a nice tread on that.
Check that out! Be aware there are a lot of FT232RL fake chips around.

Please do not try to connect a cheap sub-serial interface. Some people clam that that workswell, but you could fry the communication port on your Curtis controller.

Satfrx: Could you please help with a link to the thread on Buggies gone wild forum, or a more detailed description of the programmable FT232RL chip?

Cheers

The bussgies gone wild tread is a bit long.... (104 pages now)
most important info is in the last pages. (10 pages or so)

Google for "programming curtis controller" and I am sure you will find the buggies tread on the first page.

The basics are buying a FT232r berakout board or cable.
Like this cable...  TTL-232R-5V-WE

 
Attach the desired connecotor (molex 12V P4 ATX) to the 3 wires  (GND, RX and TX).
The 15V/5V wire/pin is NOT to be connected.

Download the FTprog tool and program the RX and TX datalines to invert.

This should work with the older software. (find the comport number in windows devicemanager)

If you also use FT-prog to change VID to 1fa1 and PID to 00c8 than the newer software can be used. This works only with user settings, it needs a small adition to the registry to use OEM.
You do not need to programm the complete datablock into the chip. Just VID and PID is enoug. Curtis probably still uses a 74HC14 or something to invert the signals.
We can simply program the tx and rx lines as inverted signals. This works fine with my 1234 controller.

Be sure to get an original FT232r cable, reakoutboard or chip. There are a lot of copies around that look exactly like the original.

I bought some Arduino download cable or something, this is rubbish, one can not program these chips allthough they look like the original.
I complained to the seller he told me not to expext a proper chip on ebay.
FT232RL USB to Serial adapter module USB TO RS232 Max232 for Arduino download
You might find these will not work.....
But offcource you could always use onle like this and invert RX and TX lines using a 7414 or 4704. (only with v3 software)

Hi, can someone post a link to the old v3.12? The rtf. file that Ampman provided I cant get working. I have an 1236 controller.

The links still there in post #1, but you have to change it to an .exe filetype
This site wouldn't let me upload exes so just changed it to rtf to put it here

...

Please can you explain this a little bit more? How does the registry fix look like?

Do I have to use this max232 chip? Cant I just connect the molex pins to rs-232 and shoort the pins out, like ampman posted in the first post? thank you.
