PINNED - Info on PROGRAMMING PGDT and others

You simply want a genuine one of these TTL-232R-3V3-WE ... a diode and a resistor..... the Chinese equiv leads often work but no guarantee.

Woody, could that cable be soldered directly to Anubis's 'Wizard orange programmer' ?

[woodygb]

The Anubis board outputs SERIAL .

I had success using a MAX3232 .... that outputs TTL .... and connecting the TTL output to a Chinese USB FTDI cable.

Have you managed to open the Help files inbuilt in the programme. I haven't been able to open them yet.

OK, so I got the cable working somewhat, I think... The Kenwood cable I got looked just like the one in the pictures, but when I cut the end off it only has three wires (black, red, and white). So I installed the cable drivers on my PC, twisted the white and red wires together, and connected it to my chair plugs. I setup the software to the same comm port as the cable. With the cable hooked up to the chair, I powered on the controls and it seems to go into the diagnostics mode or whatever (the leds flash and run across the meter bar). In the program though, in the lower right corner, it keeps flashing between "comms inactive" and "comms active", and when it flashes to active the box next to it says VR2. But it won't stay active, in goes right back to "comms inactive", and then a second or so later it's "active" again, and just keeps flashing between the two...

Any ideas?

Same for me , i cut the end off the UC01KM Kenwood cable and only three wires.
Red, White, Black

So we Twist the Red and White together and solder to middle pin of XLR ?
and use nearly any Windoze other than XP Pro ?

Just making the lead up for JohnFletcher viewtopic.php?f=2&t=5231#p83752

[woodygb]

READ this post about wire colours.

viewtopic.php?f=2&t=2111&start=720#p69342

[gcebiker]

...i used the diagram from viewtopic.php?f=2&t=2111&start=800#p75551

No diode, its in the post now.
I am sure John can trade someone an ice cream for a diode if it weirds out. (he makes fresh fruit ice cream)

[JohnFletcher]

Managed to try and spend some time getting everything (not) working.

When the lead is plugged unto the USB port it is instantly recognised and the driver loaded by Windows 10. (looks good)
The 14.4.3 software loads and it recognises the port Com3 (Tried setting to Com8 and it did not work either). (looks good)
Plugging the XLR cable into the base of the joystick controller (where batter recharge lead goes) when the chair is powered up results in nothing but COMMS INACTIVE from the software.

Does it look like I need this diode adding or is something else up?

[gcebiker]

Yeah looks like you need the Diode per Woodys Diagram above,

Sorry John, i was not aware of this difference 3/4 wire till i cut the cable to put your XLR plug on.

[woodygb]

John ...I note that your using the SERVICE Software ... DON'T.

It will NOT allow you to see any of your parameters ... you'll just get a blank screen ....but it will allow you to inadvertently over write them and Fudge things up.

Add the diode ...see what heppens.

[gcebiker]

Oh i thought that was the right one, good to know.

[gcebiker]

In the diagram Woody,

Is that rectangle the USB socket and only the RED/Gnd actually get connected to the XLR ?
(as red/white are connected by the diode ?)

Tony

[woodygb]

Rectangle is the USB adater and the wires that come from it.

Ignore any colour references ..the Chinese seem to use any colour combo.

So ...GND of USB adapter to pin 2 of XLR

RX of USB adapter to pin 3 of XLR
TX of USB adapter to diode and then it also goes to pin 3 of XLR.

[JohnFletcher]

Added the 1N4148 signal diode to the white wire as per diagram.
Changed software as suggested (9.8.2).
The software loads and it recognises the port Com3.
Plugging the XLR cable into the base of the joystick controller (where battery recharge lead goes) when the chair is powered up results in nothing but COMMS INACTIVE from the software as per before.

Any idea what’s going on or what to do next?
Very frustrating as I really need to sort out the chairs over jittery steering going steep downhill.

[gcebiker]

Is this down hill run on a full battery ? i wonder if its over volting as the motors turn into generators ?

[JohnFletcher]

IDK what I do know is that the steering is abysmal verging on dangerous and the joystick over sensitive which causes further problems in a runaway situation.

Batteries we full one time and second time 3 bars down but that was a worse run away.

Definitely enough power and range.

[Burgerman]

Remove ALL turn accelerations and decellerations. And all minimum turn accellerations/decelerations.

Lower motor compensation by 30 percent.

Test...

[gcebiker]

Can you post some pics of the controller ?

...could it be the wrong cable ?

[farmer]

I have a Jazzy 1120 that I am using while I work on my Permobil m300 I made a cable for the Jazzy which has a Pride plus joystick control combined and I need the software to program it can someone point me to were I can find it.

[farmer]

Thanks

[JohnFletcher]

Can you post some pics of the controller ?

...could it be the wrong cable ?

Unfortunately It's behind the batteries, so that may take some time.
Reading the manual, it looks likely that my chair is R-net so I need a dongle.
Hi ho...

[DaveTheRave]

Hi guys, I’m new to the world of power chairs. Very grateful to this forum, it has helped me get this far quickly. Please forgive me for a long first post, in which I tried to put pctures but failed.
A work colleague has a Quickie powered chair with a VR2 JSM controller (D51269.01). All is fine, but we are located some way from the nearest repair centre and having him out of action due to a fault on the chair is not acceptable. A second chair was bought second hand as a spare, the chairs match but the second has a VR2 JSM-A-L controller (D51269.02). This has been ‘adjusted’ and the driving control is not right. Somewhere the settings are off and cause some unexpected reversals of direction.
Your forum was found and an attempt at building a usb to serial lead made, but this failed. At this point I was called upon to get things working.
I took the lead we had, read up many pages from this site, and tried connecting. Comms inactive. Then got out some test kit. An oscilloscope showed up a problem
(Scope36b)
This trace shows the signal going to the chair, followed by the chair’s response. Sadly the reply is too small for the RX circuit to consider it a proper signal, so it is ignored. I tried quite a few options to fix this, but nothing worked. So as it was 5 o’clock I went home to think about it.
Next morning I arrived with great plans to throw some serious electronics at the communication problem, but over the first coffee of the day I read some more pages from the forum. I found this picture posted by DSmidget
(Programmer cable)
This is my kind of information, it tells me stories and makes life so much simpler. So I got building and in a couple of hours and a couple of tries had this,
(interface)
It uses the biasing/matching circuit from the interface pictured above, and amplifies the return signal to give the RX circuit a chance. The joy when the programming software went over to comms active and then read the settings from the chair; this caused an outbreak of happy dance. The circuit may be robust enough to work with almost any USB to serial convertor that has a 5v line. However I have only tested with 2 types here and they both work, one is a FDTI and the other a cheap 3 wire device which I had to break open to get at the 5v. Neither worked with just a diode, or with the addition of a pull up resistor.
I copied the settings file from the chair that works well and, after saving a copy of the poor settings, loaded it into the second chair. Brilliant, the second chair now drives just like the first. But we have lost the use of the actuators that control the seat tilt. Humphf.
So as we only have the service version of software, we cannot adjust parameters on the chairs to get the second controller to drive nicely and control the seat tilt. I have printed out the settings from both chairs and can see where the setups differ, it would be great to be able to get full function of the second controller.
Anyone care to drop me the full software?

[woodygb]

I currently recommend this specific FTDI lead that supports +3.3V UART signals AND has a 5v power output.

TTL-232R-3V3-WE Version 1 cable. Supports +3.3V UART signalling and +5V/75mA power output

The simple addition of a diode and resistor is all that is required with this lead.

[gcebiker]

enlight22 this is the thread with the information for PG Drives Technology - PGDT

Forum members are very helpful here but we need some small but important details - pictures or model number of the actual Power Module.
I upload my pictures to my facebook account and then link the picture here, that is one way to stick a picture inside one of these threads.


With specific information, we can give you more accurate answers. I have to go to work soon but will check back soon, seems like we may be in the same time zone (or you are still awake trying to nut out the trouble with your chair).

[peterik]

what program be used for the power module

[peterik]

cable may be? electric wheelchair to RS232 male

[woodygb]

what program be used for the power module

No idea what the power module is ...need a BIGGER picture .

Any name or numbers on module?

[Burgerman]

Looks like an ancient Penny and Giles one that used to be used on an arm with integral joystick relocated with external joystick. I doubt it can be reprogrammed. All old analog design. Could be wrong...

One of these with external joystick... https://cdnqs4p.quicksearch4.com/i/aDov ... 8800005007
