PINNED - R-Net for dummies

[Burgerman]

Connections!

The 2 inhibit connections each have 2 blades. For a microswitch to set speed as it tilts or whatever. Or for several different inhibit speed "bands" based on a bunch of resisters. See manual, https://www.wheelchairdriver.com/doomed/R-net.pdf
You cant see them without removing waterproof rubber bungs...

Same rubber bungs on the battery connection for on board charging. Neither this connector (or the 2 inhibits here) are used on most chairs. You could use this as a 12A max 24V OUTPUT. If so add an 10A fuse. Or less. It is "live" 24/7 connected directly to the battery.

[Burgerman]

One of the things I bought on eBay recently was a brand new R-net attendent joystick.
Why? Well I dont need anyone else to drive my chairs! But I do need Radio Control!

So I am going to use that. Why that? Because it was cheap (£20 delivered new). And because its small and simple to integrate and program with RC priority as and when needed.

I will use my WoodyGB interface. It allows me to plug in 3 channels from my RC reciever. And it outputs a DC voltage swing. And it has failsafe. And the R-net bus has a 12V power supply as well as a 5V supply inside the Attendant joystick. I will remove the actual joystick. And solder in the relavant wires. And I will be using my 2W LoRa capable transmitter on 915mhz. Why? Its a Long Range (hence lora) system. As such it has around 50 to 100 mile air range! Overkil maybe. But that means a couple of miles of reliable solid GROUND range around my town and around things that block signals like cars, vans, buildings etc. So for controling a powerchair its much much more reliable and its tiny.

So when it arrives I will elaborate and explain how. Becaue Woody can provide the interface, and the programming of the R-net will be here.

This £20 accepted, new!
It will not need the joystick, (or case?), just the board and will include a RC reciever will sit on the seat on various chairs or be fitted permanantly out of sight depending on need.

Will use this 915mhz frequency hopping high sensitivity long range cheap RC reciever.

And my slightly modified dual frequency 2.4ghz / 915mhz 2 Watt 33db transmitter now built in internally. Overkill but safe and long range.
This thing can use both 2.4ghz and 900mhz at high power simultaniously while jumping frequencies. Its basically a bomb proof secure radio control connection where theres a lot of RF noise. Even in busy urban areas and through walls/vehicles etc.

Are battery & motor connectors standard? Where to get them?

[Burgerman]

They seem to be similar across SAME brand. At least the ones used on PGDT stuff like pilot+ and r-net etc. But watch cable sizes. Older ones may be smaller as controllers were 50, 70 or 80A. And now with heavier chairs we use 100 or 120A controllers.

As for other brands, they are different I think. Cant say I know for sure.

You can order from various suppliers, including the controller manufacturers. Their PDF tech files also tell you where to get, what cable sizes, how and what to use to crimp PROPERLY etc.

For e.g its here for R-net.

But eBay is often cheaper... Battery loom.

Will a Permobil branded R-Net joystick work on a R-Net Bounder?

[Burgerman]

Yes.
If its an r-net one definitely, as in the CJSM2. If its a Permobil PJSM copy type one with smaller screen, 2 buttons mssing, probably, but those are a little different regarding firmware etc.

Expresso in n york put one on a quickie. Screen isnt only smaller, darker too, harder to see outdoors.

[emilevirus]

When programming, what profile does a led joystick use? Profile 1 I suppose?

[Burgerman]

Any.

But if a SINGLE profile is configured and programmed properly you only ever need or want 1 profile anyway. You just program speed 1 (not profile 1) to do all the correct turn and movement you want. Then do the same on speed 5. And that gets averaged between both as you go from 1 to 2 to 3 etc.

[emilevirus]

I'd have thought it'd use the profile 1 and use min/max as you play with the speed just like the CJSM. Thats good to know. Thanks!

[Burgerman]

LED ones can do everything the rest can. Except lights.

But the lights thing is true of many joysticks as in the US as lights are not compulsory and a silly $$$ extra. Or on 4mph chairs no lights required in UK. So having joysticks that have a lights and indicators button would be a bit odd. Most high end joysticks do have lights/indicartors here in UK.

The difference is really about information, total distance covered, Trip distance, programming (OBP), speed display, error codes, what seating mode, set speed number, set profile number, etc on screen. Makes it easier to use seating functons for e.g. Makes them harder and more rustrating to use without. And the CJSM2 ones have dedicated buttons that can be mapped, and rubber ones around the screen that can have several uses, also be mapped to control for e.g seating too etc. And infra red control free, and BT options at a price as well.

When you talk about LED, it's from the CJSM1, right?

[emilevirus]

Here my govt provided one has led connected to the charger port and a crappy switch that works like twice yet it does have CJSM2. Probably the lighting module is too expensive. At least they use the seating module now. Many years ago it used to be all on external switches.

[Burgerman]

The cheaper 90a power module allows an actuator output, inhibits etc all built in. Which is why its cheaper. You dont have to buy a seating module.
If theres more seating functions then it makes more sense to use the 120A module, and a seating module. In europe thats almost always a 6 channel seating and lights/indicator module called the ISM6-L where L stands for lights.

In the US if they buy enough you can get that seating module without the L and its cheaper presumably...

[BCrip71]

What is the difference between a 120A expandable and non-expandable module?

[Burgerman]

There is only 1 type 120A power module.

Here is 3.
In the mddle.

[BCrip71]

The Bounder has two on their order form:

Non-expandable R-net 120A power module - No Charge
Expandable R-net 120A power module - $560.00

[Burgerman]

Theres no such thing. There is only 1 120 Amp power module.

They likely mean:
- power module.
Or
- power module + a SEATING MODULE... The ISM6-L

Those are £40 on ebay.

I bought a 120A power module AND a seating module, (does 6 seating function and lights), together for £50...
Including a bus cable! About 10 days ago.

I was asking you this because the cjsm1 can use lights and also, for example, tells you the total distance traveled and many others. It is not clear to me if I am talking about the same thing...

[Burgerman]

LED is like this... EBAY £50 NEW

It can do everything, seating, modes, speeds, etc.
Not lights. (There is also a version of this that can also do lights below.)

*****************************************


The CJSM (1) has a small screen, made of plastic and is the same. Can do everything but displays more information. That too can be with or without lights. EBAY £80 NEW

*****************************************

The CJSM2 is the best one, bigger screen, see in daylight, mappable buttons, metal shell. Also B/T (option) and Infra Red. Also with or without lights.
EBAY £125 - £150 NEW

ALL3 types are plug and play interchangable. All can do seating options, modes, and speeds. Most can do lights.

[emilevirus]

I find the CJSM2 to be the most "crappy" one. Buttons just stop working after a while or very hard to press. The power button doesn't spring back/gets stuck. Water gets in easily. I had a CJSM1 before and didn't have a single issue. It wouldn't be hard to make it water tight. Most of us still use their wheelchair under rain.

[Burgerman]

Maybe. But the plastic cjsm1 fail where the bottom of the screen corner cracks around the case.

So they all wear out. But ebay! Spares. On the shelf...

[Raro]

okay I was confusing it

I didn't know that the CJSM1 was plastic. I bought the led one because I need a light one. Do you know if CJSM1 and led one are comparable in weight?
Also is the old CJSM1 compatible with a new PM120? The first version without a color screen.

[Burgerman]

CJSM stands for ColourJoyStickModule. The early one, plastic, small screen, was later called CJSM (1) so we dont mix it up with the CJSM2 which is its proper name.

CJSM2 is metal, bigger screen, heavier, and more capable.

LED joysticks, with or without lights also plastic. Not much difference in weight and a tiny bit shorter length.

ALL THESE are interchangable. With the R-net system.

FULL R-net system. https://www.cw-industrial.com/sites/def ... ochure.pdf

What R-net 120, 2 module?
Unless you mean the permobil version, at which point only they know. Thats not standard R-net stuff.

All joysticks, seating and lighting modules, gyros, programmers, and attendant or omni devices are compatible with the 50, 70, 80, 90, and 120A power modules. If its R-NET it is compatible!

If its some 3rd party company part, like permobil seating, power module, gyro/stability module or seating/lighting/BT etc then probably not and you wouldnt be able to program it, it may be or may not. Their PJSM works, but is missing buttons and hard to read outdoors.

[Burgerman]

Also is the old CJSM1 compatible with a new PM120? The first version without a color screen.

What new 120 pm?
What CJSM1 ?? They all have screens. Thats why they are called ColourJoyStickModule 1.

THIS is the ONLY CJSM (1) and I recently bought this one by offering £80 which was accepted and its brand new.

[emilevirus]

No I mean the early one. The screen was monochrome with green backlight.

[Burgerman]

What you are saying is impossible. The screen on a COLOUR joystick, the reason it is called CJSM (Stands for Colour Joy Stick Module) is because those are coloured.

If a monochrome R-net one has ever existed then it would obvously not be called colour? And I never saw such a beast.

You must be refering to some other brand like curtis instruments or something.

[emilevirus]

No, it was before the color one released. It's everywhere on eBay as well. It's on the cover of the manual as well: https://amylior.com/wp-content/uploads/ ... nual-1.pdf

[Burgerman]

Never saw one. Might be everywhere on US/Canadian ebay, not here though. But its not a CJSM as its not coloured. That old r-net pdf file from 15 years ago refers to it as JSM but I suspect that it will just plug in and work like every other r-net part does.

Dont buy one though they are ancient! You can pick up new versions of it (actually brand new), £80 or 100 US on eBay as above..
