you're in for a long trip down frustration lane, and it's no fault of the controller or whoever sold it to you, it's just the nature of setting up an ultra tuneable controller like a Sevcon Gen4.
If, as it seems to be tha case, it is possible to set up the controller with a proprietary piece of software (in fact, this is the intended way to do it) while it is like a superhuge PITA without that software, then, frankly, the seller was misleading me when he told me (in particular as I am obviousely not knowlegable of the matter) that no software at all is needed to use the controller!
consider the following:
Somebody buys a piece of hardware for his linux based computer. Now, if the guy is told that he wouldnt need any additional software to use the device, then he certainly expects that the driver software is either included or freely available, regardesless of the fact that he could write his own drivers because he could find all the infos necessary of the hardware. He would feel even more screwd, if he later found out that there is a proprietary software suite for the device with drivers and many more usable features.
If a device is meant
to be used together with some other device/software, then it is just misleading to say that nothing else is needed to use the thing, even if there is a workaround. Particularly so, if the *workaround* requires much more effort/knowledge to accomplish than the intended way to use the device.
So yea, I feel screwd. Also, I am not rich, I have two kids, a wife and two part time jobs because my phd scholarship is just not enough for 4ppl. Ironically, the only thing I dont regret of having bought (for my conversion) so far, is the a123 batteries I ordered from a shady source in china, where everybody told me that it was a risky thing to do (also I knew it was a risky transaction).
just my 0.5$
PS: All I wrote is based on the assumption that using the proprietary software faciliates setting up the controller.
