Tm1000 with hobbywing rpm sensor
Hi all,

Please could you guys help me with wiring the above.

Will be using 3gx

I have ordered a tm1000

Hobbywing rpm sensor comes with futaba style connector

Already have a spektrum sat connection to rewire the futaba style connection.

Please could somebody explain how I wire it up I'm sure I saw somewhere I had to swap the black and red wire but can't find it now.

Many thanks,

Paul

If you apply some logic you should be able to figure it out for yourself regardless of the configuration.

The sensor input to the TM has the same 3 wires as a servo lead.One power,one ground and one signal.The colors for each are standardized but may not be the same between different brands.
Futaba uses white,red,black JR/SPM orange,red,brown Hitec yellow,red,black.
The orientation in the plug is always the same so they can interchange.
Take a very close look at a lead that goes into the TM module.
The orientation/order of the leads in a telemetry lead plugis different than it is on a servo lead plug.

As long as you match the functions as they are related to the specific plug they are being used for you will be good.
Blindly swapping or connecting something based on what someone tells you without understanding where and why can easily lead to a big problem.

Red,black and red,brown are pretty easy to identify as power and ground. The signal wire will be either orange,yellow or white depending on the lead.

Ive made many custom telemetry leads.I use a cut in half sat/remote lead for the telemetry plug end.If you do this you must see that the colors are again different between a remote lead and a telemetry/SPM lead.Again compare and apply logic.

As long as you keep the brain engaged,pay attention and match the function of the wire from plug to plug you will be fine.
If you are guessing and dont get it right the magic smoke will leak out.

For the most part servo connections and many others have the red(power/positive) in the center with the ground and signal on the outsides.Plugging one in backwards by accident generally cant do any damage from reverse polarity.
If you study it carefully you will notice that the orientation of the leads in a TM plug put the power on an outside pin,neg in the middle and signal on the other outside.Potential for a huge mistake when matching connectors.
They dont go straight across from plug to plug like a servo lead does.
Thats why I say to give special attention and match the function of the wire to its position in the various plug ends.
Like I said with a little logic and attention its easily understandable.

If your going to use a cutoff sat/remote cable pigtail like I usually do and your connecting it to a black red white lead it goes like this:
red to orange,black to black and white to grey
