Spectrum DX6i extra auxiliary switch?

(1/2) > >>

Hotglove:
Please excuse my ignorance, the answer may be simple (I certainly am) I am planning to replace an ESS One sound module with an ESS One Dual Plus. One reason for the change is to be able to play home-made mp3 files as auxiliary sounds. I use the Spektrum DX6i tx and AR 610 rx
I currently use throttle and rudder as normal, with Aux channel controlling power on/off to the sound module and gear channel controlling lights.
This leaves the aileron and elevator channels free.
The sound module has a "Y" cable to connect to the throttle, battery cable and a single core cable to connect to the aux channel (currently in use to switch module on and off)
Is there a way to configure either the ele or ail channels as an on/off switch or an alternative set up?
Thanks

Afraid not, Spektrum's programming will only accept what is connected to it currently as per most radios

The switch on the Tx does not operate an actual  switch in the Rx. It merely outputs a fixed signal which the sound system recognises as "ON". All the channels are capable of outputting this signal depending on the position of the lever. Therefore you could use any of the spare channels to operate your second sound channel - you just have to work out by trial which way to move the lever. Obviously it would need to be a none self-centering lever.
You can experiment by attaching a servo to the switched channel and observing what it does when the switch is operated. Then you can see how to use your spare channel to replicate this.

clockworks:
You can convert a stick channel to a switch channel with a bit of rewiring inside the transmitter.
A stick is just a variable resistor (potentiometer). If you replace the variable resistor with a 2 position switch (SPDT) and a couple of fixed resistors (one equal to the resistance of the potentiometer at "stick down", the other equal to "stick up") you will effectively have a stick channel that has 2 positions - full up and full down. This is all a switch channel is.


Fairly straightforward rewiring job, just need to remove the 3 wires from the stick potentiometer and drill a hole for the switch. The centre wire from the potentiometer goes to the centre terminal on the switch. Solder one end of each resistor to the other switch terminals, then the other two potentiometer wires go to the other ends of the resistors. If it works backwards, just use the channel reverse function.


Probably best to use the left stick left/right channel for this, as I can't see that ever being used for a boat?

Captain Flack:
This is a shot in the dark but can you not use a receiver controlled switch?  I know you can get latching or non latching %%
