I have bought a HobbyWing Platinum 200A OPTO ESC v4.1 and a HobbyWing Multifunction Programming box. I thought I would programme the ESC out of situ from the F/W aircraft. Hah! So I thought!
First problem is the connection diagram in the manual doesn’t match the ESC. The ESC has just one non-power lead which I assume to be the throttle lead to the RX with a single yellow wire added which I take to be the RPM signal plug.
Problem number one - the diagram shows the throttle wire And a program wire coming from the ESC. Something which is not the case realtime. I have tried some wiring alternatives as illustrated with the throttle lead unconnected to the programming box and just connecting an extra supplied lead between the p/box and ESC with the separate battery connected (as it's the Opto version)to the p/box, as photographed. The end result that the [B][B]"Connecting ESC" light comes up, but that’s as far as it goes and doesn’t progress on to the “current profile” display from which to begin programming. The same happens when I use the throttle lead from the ESC to p/box which I know its not the way to go. Any ideas? Thanks

you might have better luck over at rc groups if you haven't already posted there.

You need a male to male lead. The servo port marked -/+/P is for programming.

Fairly certain the ESC needs power to the mains as well before it can be programmed.

you need to power the esc aswel connect the esc to a 6s battery then you can programm the esc
i have a 130 esc from hobbywing and needs also a extern main battery to get in to the setup
with the programm box and connect that to the side in your pictures

Right, I think I've got it, gents.
suds & asjen - as I understand it I need to connect the ESC to a main flight pack (in this case a 6S lipo) to get the programme box to work.
Irb75 - I have a male to male lead that came with the LCD box so this should be ok.

Last question. As it's an OPTO ESC and I am powering the RX using a 2S lipo, presumably I don't need a separate small battery into the programming box? Sorry to be so dumb!

Male to male lead is here I guess.

Hook male to male to esc and box. Then plug a battery into the esc. Then I think I usually push any button once on the box and it should connect. I've only needed to use it a few times

Thanks NappyRoots2182 I will give it a go.
