I know and personally il like the Ethernet more.

But from a business point of view both Serial and CAN are automotive rated (CAN much more) and also CAN works also in disturbed environment with a lot of EMI , I don't know if Ethernet can work in a noisy place like a running controller ( or you can program the Soliton only with the main voltage turned off ?).

Working with the controller on ( or even with the vehicle moving) is a great thing for debugging and optimization , but you need a connection able to work with a lot of interference coming out from the controller itself and all the power cables

Ethernet uses transformers on both ends of the connection and balanced, differential signalling. It's pretty much the most noise-robust communication standard that still uses wires.

So yes you can change settings on a Soliton controller while it is actually operating (though we do warn against that for the obvious safety reasons). Besides, how else would our data logging program work?!

well this are good news for me ... I'm the only one to push for ethernet , everybody also here want CAN ... but for me Ethernet is much easier to manage and don't need computer adapter , program or other stuff.

How much do you thing is the added price for a controller to make it "ethernet" compatible ... the Raspberry Arm computer cost 25$ so I think adding an Ethernet interface will cost less

I can't quite figure out what you are asking here... Are you trying to make your own controller and want it to have an ethernet interface?

[athlon]

Yes and no ... A friend of mine build his own controller and there was a lot of talking about interfaces ... I was thinking about ethernet like a printer server or a router ... but nobody liked .... (Typical aswer was .." I nobody use Ethernet on controller there is a good reason") ... so wen I found the Eth interface on Soliton i was surprised .. an i'm not alone anymore

(Btw I like ethernet a lot because I use Linux computer and configuration software are for Win only)

I greatly appreciate Tesseract's choice and hope that it replaces the historical choices of dedicated Windows app or -- shudder -- special hardware just to program the controller.

I'll be running Ethernet to a WiFi gateway so I can program the controller from my phone

Test drove the Rabbit EV

http://www.evalbum.com/4204

first test runs went fine, car is fun to drive, yeahhh

but on the third test run the controller error light stays on and the webpage back reads back that the "throttle is not at zero"

Its the evnetic throttle and is at zero so I cannot figure out whats wrong. Its running 1.4 so I will update today and see if that fixes things.

Any other ideas??

Check the entire throttle linkage or cable for binding. Re-calibrate the throttle. Try adding 3-5% of deadband as recommended in the manual. This is not a problem with 1.4.

OK that worked, I set the deadband to 5 and it cleared the code. The throttle linkage works it was all the way closed at all times, so that wasn't the problem. Could it be noise? or maybe my electrical connections aren't the best, I will clean them up. One problem I found quickly is that my TDK lambda DC/DC with 18 amp output was crippled by the current required by the brake pump, so I will put a small AGM battery inline with the DC source to help with current spike requests.

The Evnetics controller is really easy to install and is absolutely quiet and very tame. The throttle response is smooth as silk and the car makes no noise just the slightest humm from below, about the same amount of noise that a Nissan Leaf makes!

So far I'm a happy camper not to setup the gauges. Looks like I need some voltage divider circuits for both voltage and amp readings from batteries. So time to set those up today and also the brake and reverse inputs.

Later

It could be noise from bad connections, sure, but it's unlikely that noise from anything else could cause a problem. It's not unusual to need to use a little deadband even with our throttle assembly.

Thanks for the comments, btw - its always nice to see happy customers.
