Binding Trex 150 to Spektrum TX puzzle solved!

When I first received my Trex 150, I bound it to my DX6i DSMX and later when I have DX8, I just couldn’t get the power to the Spektrum DSMX satellite remote receiver either setting my DX8 to 22ms DMS2 (no pressing on the set button) or 11ms DSMX (with the set button pressed when connecting the power). Then I read the Align Trex 150 again and it says that I have to connect the 5 to 6 volts power to one of the 150 MRS’s receiver channel. While I was making the cable adapter for 1S lipo for the job, I had a closer look at the bind plug and it looks like below:

I then take a look at the larger regular bind plug and clearly see that the bind plug is simply the jumper between the 2 wires at BOTH ends which are the GROUND and the SIGNAL ones. But as you can see my mini bind plug came with WRONG connection! But how on earth that I managed to bind it to my DX6i with no problem!! Anyway, I used a safety pin to pry open the tiny plastic locking tab and moved the center wire to the other end, so it looks like below:

Now all work just fine, go figure!!

Umm... Im not familiar with the 150 specifically but you probably need to look at a regular servo connector and the mini jst servo connector closer.Take special care to note the orientation of the colors and how they go into the connectors.
The wires on the mini are not oriented the same as the full size connector. The power lead is not in the center.The center is Ground.True enough that to initiate bind the signal and ground are shunted.On a mini connector that is the center and one of the outside leads. Connecting the 2 outside leads will shunt power to the signal lead. This may not turn out so well.

RE: The wires on the mini are not oriented the same as the full size connector.
Not true.

In the beginning ALL servos have red = positive, black = negative and white = signal.
Then came the red, brown, yellow which equal +, - and signal respectively. But someone suggested that if you confuse, then the lightest color wire will always be the signal one.

As for the Trex 150 that uses small rotary servos which still have the same wires arrangement (red positive in the center)as you can see from the pictures below. And that’s why I has to connect the 2 wires on both ends for the binding purpose.

A quick look over at the Align website, parts for the 150, shows that the binding plug CLEARLY needs to have the short wire placed on the OUTER pins of the plug, not side by side.

The plug as Tanasit received it, was built incorrectly. His "modification" -- made the plug correct, as it was supposed to be.

I am corrected.Ill be...
As I look around there appears to be multiple configurations for the orientation of the wires on these micro plugs.Definitely different than the ParkZone of HH stuff.I guess there isnt an acceptable standard on these micro connectors.Somehow it doesnt seem to make alot of sense but it is what it is I guess.I guess I will the one to take extra close note of how the leads are oriented when changing things around.

Its probably eventually not going to turn out well for someone.Glad you got your 150 figured out without alot of grief.Thanks for bringing this to light.May have saved me or someone a big problem by making assumptions.
