"Automatically get recommended drivers and updates for your hardware" http://windows.microsoft.com/en-GB/wind ... r-hardware

That will stop it... The ONLY version that works on my laptop and desktops is 3.2.0.0. And once you install a newer version its hells own job to stop windows reinstalling the newer one instead. You must delete these from the system. Reboot and start again.

For what its worth there may be good or bad USB sockets (hubs are usually bad) at the front or the back. Try all of them. And all ports from 1 to 8 with each. Reboot each time.

As I've said, I'm using the new version on the awesome cable. I plugged it in, windows went off and installed different drivers and it worked.
That's how it should be. And only use a hub if it's got it's own power.

I'll plug mine in later and see what drivers windows installed.

[Burgerman]

Could be that the very newest drivers also work. I haven't tested them for some years. Allowing windows to auto update used to kill it. As might the next update... It does the same to my graphics card too. Best to use whatever revision works best.

I don't allow windows to auto install anything. Learned how many problems that causes the hard way far too many times.

The cable I'm now using is based on the FTDI chip...I suspect that this is also Terry's

This lead has an extra extension ... nothing special inside just cross over wires...it allows the std wheelchair programming lead with Neutrik / XLR plug to be used with the scooter controllers.

Pictures taken today.

Hello!
This is your new cable?
Kenwood - outdated?
And what kind of adapter in the photo?

[woodygb]

Yes it's an FTDI based lead.

6P FTDI FT232RL USB to Serial adapter module USB2.0 TO TTL RS232 Cable F/Arduino


Features :
Red wire： 5V
Black wire： GND
White wire： RXD
Green wire： TXD
Yellow wire： RTS
Blue wire： CTS
FTDI based USB to TTL Serial Cable are designed using the the standard FT232RL chipset.
The cables provide a fast, simple way to connect devices with a TTL level serial interface to USB.
RX and TX LEDs indicator
The cables are available with a 6-way SIL, 0.1" connector
TTL levels is 5V
The TTL-232R cables are a family of USB to TTL serial UART converter cables incorporating FTD's FT232RQ USB to Serial
UART interface IC device which handles all the USB signalling and protocols. The cables provide a fast, simple way to connect
devices with a TTL level serial interface to USB
Each TTL-232R cable contains a small internal electronic circuit board, utilising the FT232R, which is encapsulated into the USB
connector end of the cable. The other end of the cable comes with a selection of different connectors supporting various applications .
Cables are FCC, CE, RoHS compliant and are available.
Cables are available with either a 6-way SIL,0.1”pitch connector, a 3.5mmAudio Jack, an 8 way, keyed 2mmpitch connector
(intended for use with VMUSIC2 or VDRIVE2) or bare, tinned wire ended connections

Where to buy or how to make this adapter?
I am your parcel has not yet received. Waiting. Mail long runs.

[woodygb]

EBAY

http://www.ebay.co.uk/sch/i.html?_from= ... o&_sacat=0


The drawing is how I make my leads.... the photo simply shows a wheelchair programming lead with an additional adaptor for the S-drive.

I hope the cable arrives soon.

[woodygb]

The cable in the photograph is constructed like this.... and is dual purpose.

Just a quick side note: mail to Russia (St. Petersburg - Санкт-Петербург) takes 4 weeks from Vienna. Mail from Vienna to Kamtschatka (Камчатка) 7 weeks.

[woodygb]

Posted on 16.01.2015 and the package arrived yesterday.

[woodygb]

There has been a report of incorrectly programmed ebay leads ...if your FTDI lead doesn't work ..see link .... for info and a solution.

[Princess Myia]

Wow, this is all double Dutch to me.
BM, fancy a visitor lol

[Burgerman]

Dunno. Are you a slim fit attractive single young blonde?

Seriously, if you want to drive hundreds of miles I could. Is your controller OVAL shaped, not to get too technical...
And do you have 2 or 4 pole motors?

If you don't know about motors ask your "engineer" to help!

WoodyGB will probably make you a lead. But you will need a person with a computer to change your settings. This is a much easier option! And cheaper.

[Princess Myia]

very happily married
Need to check the motors and the controller is oval yes, will post pics later, think it maybe easier.
If Woody could make me a lead that would be fab, could I then post out to you to reprogram or bring it over? You're not that far and if you'd be willing to do it, I would be willing to make the journey. I only have access to my parents Mac (my windows pic is being sent off for repair) and they are a bit funny about putting unknown programs into it.

Thanks BM

[Burgerman]

You cant use a mac.

I don't need a lead. That is if you wanted to do it yourself. And you should. Because while I can do a quick job here, you will want to fine tune it for yourself over a few weeks or so. And its easy. The software is safe! And simple. Find a 13 year old with a laptop.

But I can do it here for you with a hand held programmer if you want.

>>>my windows pic is being sent off for repair

This is the case for EVERYTHING if you don't take charge and do things yourself. Cars, computers, tools, everything in life. Knowledge is power!

[steves1977uk]

I can offer to help Myia since I am able to program both Pilot+ and R-Net Power Modules as I live 20-odd miles from her.

Are you able to bring the chair to me Myia once you've got it set up to drive?

Steve

[Princess Myia]

Yes I realised that as soon as I sent the reply, you wouldn't need the lead.

Yep, knowledge is power, shame I don't have that knowledge virus ate away at it, lost everything (I did have anti virus software), it's having to go to manufacturers to be, basically, rebuilt.

[Princess Myia]

That's a very kind offer Steve

Yes I could bring the chair to you once it's set up and you are soooooo much nearer

Thank you very much

[steves1977uk]

You're very welcome Myia Drop me a PM once you've got your chair set up to drive and we'll arrange a time for you to visit me.

Steve

[Princess Myia]

Ok fab, will do. Not sure how long it will be though, starting on the chair in the next day or two.

[Burgerman]

Motor compensation 2 pole 100 to 110
Motor compensation 4 pole 45

Get this reversed and it will either barely turn or ne out of control.

[Princess Myia]

These are the motors I am using plus spare ones.
Not sure if they are 2 or 4 pole motors

[Princess Myia]

Another

[Princess Myia]

Two more

[woodygb]

These are the motors I am using plus spare ones.
Not sure if they are 2 or 4 pole motors

The number of brush holders ... they are the black plastic covers over the metal blade that the wire pushes onto ... gives the clue as to the number of poles.

So yours appear to be 2 pole.

[Burgerman]

Correct. Fit only for the bin.

They are terrible. They look similar to 4 pole but really are bad. Even when new. And low in torque /weak, unreliable and have lots of backlash so they jerk every time you turn.

[Princess Myia]

Ok, thank you. Will have a look round for some 4 pole motors

[Burgerman]

Sunrise medical.
Used motors - seldom a good idea apart from just keeping something old running. Those are about the only bit on a chair that does wear out. They lose efficiency, range, torque, get noisy, develop backlash in cush drives and gears. Brakes wear, seize.

I take a set off a chair that I am about to rebuild, that SO FAR have never let me down every 2 years regardless. BEFORE they do. As I have did last week, that go straight in the emergency parts pile. That chair will be reborn, with every part either as new, or new, and blasted, analysed, measured, re powder coated, new upholstery, new bearings, tyres, motors, connectors, bolts (stainless steel, cap screws, polished), new footplate, rose joints, batteries, etc. Regardless of the way they look when stripped. Result is a new chair. One that will run for 2 years used abusively and all day every day with zero breakdowns or maintenance. I cant afford that to happen.

[Princess Myia]

Thanks for that BM, was just about to buy a used pair of eBay. Will check out sunrise
