I'm not sure which driver you are talking about in case there happen to be multiple drivers. If you are talking about mine, the most notable differences are explained in that topic, though there are likely also smaller differences (as this one was also written before the stock driver existed, though I expected it to be about like the WD-200+ given how similar they otherwise are):
If you hover over the command on the device detail page, you'll see an description of each parameter and the valid values. The best way to use them is all strings, as you have. The one difference I see is that you want on or off and not true (or false or 0 or 1) or anything else for the third parameter--again, assuming you're using my driver. Other drivers may vary but hopefully have something like this documented for them, too.
