Hello Tomas
I would like to build a telem cable from a Spektrum remote receiver extension cable with :
- original JST connector at one end for the Spirit Pro sat port
- JR servo connector at the other end for the Scorpion Tribunus telemetry port
I have read all the messages about telem cable but I am very confused with polarity and needed wires.
On the Scorpion Tribunus telemetry port, I have brown/negative, red/positive and orange/signal wires.
Usually, the Spektrum remote receiver extension cable are : pin 1 orange/positive, pin 2 black/negative, pin 3 grey/signal
So, what are the wires needed and arrangement for the Spirit Pro sat port ?
Thank you for your help.
Jean-Michel

Hello,

orange wires should be connected together.
And brown wires should be connected together. Brown/Black cable in the JST should be in the middle.
Red wires must be disconnected.

If done improperly ESC/Spirit unit could burn.

Thank you for the reply.
I understand that the Spirit only need negative and signal.
So understood for the negative : brown wire on JR servo connector / black wire on JST connector.
But you say orange wire together. I think you mean signal transmission.
However, on JR servo connector, orange wire is signal and on JST connector, orange wire is positive / pin 1 ?
I thought that orange wire / signal on JR servo connector would be connected to grey wire / signal / pin3 on JST connector ?
What is the right arrangement ?

Our cables are all orange, red, brown.
Yes, signal is orange with our cables.

You can compare with our photos how it is wired in the connector.
JST are 1. orange, 2. brown, 3. red
Servo connectors are 1. orange, 2. red, 3. brown

Thank you for advice.
Watching your cable photo, it's right. I found the right side for signal wire on the JST connector.
Conventionnal colors of Spektrum extension cable are orange, black, grey, witch is confusing.
