usb cable with PL 2303 chip you must be

[woodygb]

It isn't simple for me to explain why ...especially with the language barrier.

It isn't JUST an RX and TX...other parts are required.

Communication with programmable chips requires different protocols.

Here is a link to a page that has the various configurations required by some of the Radios ... .

[woodygb]

Buy it and try it.

[Burgerman]

It needs a bunch of things in its favour to work.

Correctly built and tested.
Correct chipset.
Correct driver that matches the operation system
Correct configuration.

Its really not a simple job to get all of this correct. I wish you luck. And when it doesent, and youy wasted time and money, and still had to supply a cable, a diode, and an XLR connector, you can still but woodygb's cable and proven solution. As you will likely still need it!

PL2303

You have all the information that I can give ... please stop asking .

Buy whatever you think will work and try it.

October will stop reading the topic first as

This is either a seriously bad translation or you are talking to a bot.

Just bought a new Kenwood KPG-4 Replacement USB RIB-Less Programming cable http://www.radioarena.co.uk/index.php?_a=viewProd&productId=628 and after cutting the plug off it I find it has only three wires, Red, white and black - no green wire. Is this right and if so which wires then connect to the pins of the neutrix?

Thanks Steve

[woodygb]

The wire colours vary depending on the whim of the Chinese / Korean supplier.

It's probably as shown in this pic.

GND = Black
White = TX ..put the diode in this line.
Red = RX





The alternative is to pop the case and put the diode inside across the TX and RX pads .... see this thread.
Then you only have two wires GND and a combined TX & RX.

Thanks Woody. Actually by pure chance we swappyed the wires around and by pure chance it worked. The new lead is now reading the controller perfectly. The original cable I made after following your instructions worked perfectly until the other day when I accidentally ran over it. If that wasn't bad enough I ran over it again for a second time the other day and when I went to check on my new build I couldn't get it to read the joystick/power module.

Anyway, and back up and running. The problem with my chair not moving is now solved. It was a programming error and after sending a copy of my settings to John (BM) he saw something that I had missed although I'm not sure what it was. Anyway I sent this file to the power module and hey presto my chair is now moving once more.

Thanks again, Steve

[Burgerman]

Pleased to hear it.

You had torque set to zero (meaning it would send no amps???) Changed to 100.

And I changed the inhibit settings from:
low 0 to 100 (in case you had an inhibit switch fault)
mid 50 to 100 (I may have left that one?)
high 100 to 100...

Can I suggest the pound shop. Diopter +3 And a bucket of anti gravity. Most of my stuff ends up on the floor too.

Also try setting the TURN DECELERATION and LOW SPEED TURN DECELERATION to 100 as I am surprised you can hit a doorway like that set to 70... I certainly cant. It steers like someone else is in charge.

[segreen]

Sure, I'll sort it tomorrow. I'm not actually using the chair. Its my latest build and the best yet. Made for a 'tetra' - not too tippy like the one I keep falling out of!

[Burgerman]

Well I did warn people endlessly that my chairs are tippy and have a small narrow/short lively footprint...

WoodyGB, Burgerman,

I've just come across this board recently and am new to power wheelchair modding. I plan on doing some beginner robot work in the near future. I've followed the schematic to make my own cable from USB-UART cable and an XLR connector. One question: I saw a reference to the "PG Drives" software. Can you post a link so I can make sure I'm using the right software? Thank you in advance and for all the great info on this board. Simply fantastic.

[rustyjames]

Hi, I believe this is the link ?: http://support.pgdt.com/Remote-Service- ... mmers.aspx

[woodygb]

Nope ..that is Service software....
It just allows you to download and upload settings .... not alter them or indeed see them.

[rustyjames]

I still have a lot to learn

[woodygb]

.

I have many Permobil .prg files and all the ones I have looked at have Torque set as zero. ... I suspect therefore that the "fix" you applied was to override an Inhibit.

[Burgerman]

I would agree except that the inhibits don't do a thing if the ALM is disconnected and it was apparently...

Mine are all set to 100 as well as torque.

[JenR]

I have a permobil c500 with pilot+ and want to program my controller
I already have a USB to TTL (5v) cable, but how do you guys connect the RX, TX and GND to your wheelchair? Do you use a plug for this or do you just jam the naked cables in your controller?

And could someone pm me a link to the latest pgdt software? Thx!

[woodygb]

You program thru the 3 pin charging port using an XLR / Neutrik plug as described and shown in numerous pics throughout this thread.

[JenR]

Ok, I made the cable using an Adafruit FTDI friend I borrowed from a colleague at work:



Installing the PC Mobility Programmer now, I hope it works

Edit: hmm, doesn't work... I see the serial to usb device in device manager, I changed it to COM8 (also in mobility pc programmer) and it says COMMS INACTIVE. My wheelchair is turned on and the battery lights are blinking (6 lights). Any ideas?

[JenR]

Maybe I soldered the XLR plug wrong?

The picture says it is viewed from the solder side of the plug, so I soldered the TX and RX to the left pin on the solder side. This is the right pin if you look at it like a normal plug.



correct?

[bgmen]

seet it http://www.crercc.com/comport.html if a chip Pl2303 download http://www.crercc.com/files/driver/PL2303_Prolific_GPS_AllInOne_1013.exe

[JenR]

I already correctly installed the driver from ftdi, and the device is listed correctly in device manager, so that can't be it I think.
