R-Net PC Programmer OEM

I am using OEM_Sunrise_EU + Meyra_V33_1_1161 and work fine.

But you are missing some parameters. And you HAVE some that you shouldnt because of module differences.

How to explain.
If I take the generic (latest) program, with or WITHOUT the meyra files added, I get the same exact parameters. Includes the SERVO options.
If I take the sunrise one, I get some parameters missing inc the SERVO settings and a few others.
If I take the sunrise one With the meyra files added, I get the servo settings back. But gain many settings, and lose many settings too compared to generic.
If I do the same with permobil oem software I see the same as sunrise but again many different parameter settings are added and also some different ones all over the place missing.

NON of these give the correct settings options or all of them needed for the myra chair. depending what you use as the starting program in your case the sunrise one, you have setting available that are not designed for a single channel unit. And some of the servo stuff too is generic, not designed for the myra custom system. For e.g you shouldnt be able to access the turn settings in the speed section or the sunrise custom seating options and a bunch of others.

Plus in order to see the same generic servo settings options all you need is the generic program (not a sunrise dedicated) without any modification of files. BUT again its not all there is and its not intended for single channel units either. In the same way that permobil have very odd (dont touch!) speed settings in their modified systems that use their own stability system.

What you really need is the meyra OEM version, complete wth their extended software (like the wheelchair builder stuff that permobil use) to configure their encoder/servo setup. Because it may well be that those servo settings or at least some or part of them are completely ingnored. I can change those settings on my own chair. And it doesent even have any servo stuff. Just because they look correct and appear in menu doesent mean they all work correctly.

Whats really needed is for someone to get this stuff from meyra...

I don't know

Does anyone have a copy of Rnet OEM for a quickie chair. I have everything for a permobil but just bought a quickie and need to program one seating function. Any help would be appreciated.

[Burgerman]

Dealer or OEM?
Which chair?
PM me...

[Radar911]

Thank you! I really appreciate it

[Burgerman]

Do you have dealer or oem dongle?

I am new here, and I very much appreciate every ones comments.

I have a Magic Mobility Extreme 8 with the simple R-Net LED joystick. I have converted it to Lithium Iron Phosphate batteries 210 Amp Hour. I bought it used and I think the max speed is set at 90% since it max's out at 5.4 mph (by gps). It has some goofy steering issues too. I would like to modify programming to match the batteries and fix the other issues as well. I have lost my right hand, so I use the left. However, i am slowly losing my left as well. I need to modify the programming as my ability changes. I live in a rural area - taking it in to get programmed is not really an option.

I have software (Setup_OEM_Generic_6_1_2). Do I need a different OEM software? I think I understand how to use a dealer dongle to make OEM changes. My main question is where is the best / cheapest place to buy a dealer dongle? My next question: is there anything else i need to know or have to re-program it?

I am in the US.

I have one too and speed caps out at about 9kmh too. What you can do is increase max motor voltage to 24v since you have Lithium. That should give you a bit more top speed.
eBay to get the dongle. Check everyday. I got mine for around $100.

[Burgerman]

Generic and newer versions, and sunrise (more options like motor voltage etc) pm me. Dongle? And generic software or sunrise software/cable etc, is about 275 uk pounds new. But here, ebay, used is cheaper.

[cybersignal]

So, just a follow up. I finally got a Dongle. I changed the voltage from 21.6 to 25 (Magic Mobility Extreme 8 chair). That gave me a 15% jump in speed, or from 5.2 to 6.0 mph. I am thinking about setting the voltage to 26 - is there any problems with that? I walk my dog every day and we usually do 4.5 miles - about 10% of my batteries (210 Ah LiFePO4). When we are done my voltage is 26.2. The voltage does drop .2 on a steep hill.

Another thing I find interesting. In warm weather I was always getting 5.4 mph. Now, in the winter i only get 5.2 mph. So something works better at warmer temp - controller / joystick ???

Anyway, I am very happy with the ability to make changes. I changed my max reverse speed to match my use. I am also slowly working on some steering changes. I am so grateful for this "site / board"! Thank you Burgerman for all your help!!!

[Burgerman]

Yes.

The system should always have a little EXTRA voltage available over and above that used to go in a straight line. Including when battery is low, and when voltage drops some under load on say a hill. So a little lowr than you may expect.

Because otherwise the following may happen.
1. Steer capability may be reduced under load or on slopes/hills or when battery low etc. Why? Because at speed, you wish to correct a turn to the left, for e.g. That requires that the left motor SPEED UP and so headroom is required. While the right one slows down. This may only be a 1V difference. If the set voltage is say 1V above the actual available voltage then no turn will happen! Or you need much bigger joystick input. And he chair may slow and be less responsive to turn command.

2. Overspeed on steep downhill

3. Max speed and control at high speeds will deteriorate as battery becomes more discharged.

Best to set it around 1 Volt below the battery 2.7V per cell point for best control. This is why its set to 21.5 approx on a lead battery.

Battery performance and voltage is proportional to temperature...
BUT the speed DISPLAYED on that joystick shouldnt change even when the chair is faster or slower. It doesent measure speed. Only measures pulsewidth sent to motor as a proxy for voltage, and the joystick position. And so a fully forward joystick position = max voltage (approx 95% pulsewidth as set in max volts. Or actual batt volts if this is set too high...) regardless of actual speed... It simply looks at the speed you set in programming and displays that.

So hard to see why summer and winter would DISPLAY different speeds. But chair should be slightly faster in summer. Not much...

[cybersignal]

I should have mentioned I am using a GPS to monitor speed, and I have a JK BMS display that monitors voltage. The voltage is the same - I am talking about 40 degrees F versus 75 degrees F. Yes, when it gets close to freezing, the voltage does drop a little - more noticeable under high load. However, that's not what I am seeing. After driving for two to three miles, the speed will increase from 5.2 to 5.4. The battery temp at this point will actually drop since its colder outside than in my garage where I keep the wheelchair. Its got to be the motors, controller or something else that gets warm with the current passing through it??? Its very consistent. Maybe the voltage setting in the controller changes with temp???

Thank you for the advice on the voltage setting. I will have to experiment and make sure I don't have a problem there, and I wont set it any higher - maybe lower.

[Burgerman]

I see.
Theres 2 other things that are relevant.
When you start a cold motor there is grease in sealed bearings and in the gearbox. And in caster bearings. So the free running RPM such as at max speed will likely increase a little as this warms and turns from quite stiff to runny... It thins out in use some as it warms.
You can hear this if you run a new cold motor on the bench for 10 minutes. It does get a little faster audibly.

This is the same reason the manufacturers of cars now use stupidly thin oil... More MPG. Mandated by the delusional climate morons. Or more horsepower as less oil drag. And more engine wear but they dont tell you that.

And as you roll the tyres warm a little that makes them softer and prssure increase but I doubt that would be measurable. So what else is different?

Nothing else could do that, that I can think of!

John ...I have just sent you ( and Tim ) a link to the Meyra R-net software that I have.

NO IDEA if it is of any use.

Cheers Woody

Hello. Please send me a link to the Meyra R-net OEM program.
