3DR DIY Quad with Spektrum DX6i TX. Wrong RX?

Newby here. I just built the frame and I’m hooking up electronics. I got stuck on the controller receiver.

I have a Spektrum DX6i transmitter and a Spektrum AR610 6CH Sport Receiver.

On the one hand the transmitter is DSM so want to connect the receiver to the SPKT/DSM connection on the Pixhawk.

On the other hand the AR610 has 6 large 3pin channel connections.

Did I order the wrong receiver? Or will this receiver work fine connected to the RC IN on the Pixhawk?
What receiver should I have?

Here’s a picture:

Thanks for the reply.
I reviewed the linked info but I’m still confused. It says:

[color=#0000FF]“Although Spektrum main receivers do not communicate by PPM-Sum their range extending “satellite” receivers do. So it is feasible to use a single Spektrum Satellite Receiver to act as a PPM-Sum receiver with PX4 and Pixhawk. Simply pre-bind the Spektrum Satellite to your transmitter using a conventional Spektrum receiver with satellite attached. Then connect the tiny Spektrum Satellite receiver to the special “Spektrum” connector on either the PX4IO or Pixhawk…”[/color]

The remote receiver recommended on this page (http://www.amain.com/spektrum-dsmx-remote-receiver/p199408). Should I buy this and replace the one I have?

I have a Spektrum AR610 receiver. The AR610 receiver https://www.spektrumrc.com/Products/Default.aspx?ProdID=SPMAR610 is a full-range DSMX receiver with 6 3pin connectors AUX through BND/DAT. Where should I connect it on the Pixhawk? It seems like the SPKT/DSM port, because it is, indeed, a SPKT/DSM receiver. However the SPKT/DSM socket on the Pixhawk is DF13 while the socket on the AR610 is a set of 6 larger 3pin headers.

Will it work with the AR610 receiver or should I buy the Spektrum SPM9645 Remote Receiver? And why is the recommended SPM9645 called a “remote receiver” and not just “receiver”?

If you want to use your Spektrum AR610 receiver you will have to purchase and use a PPM encoder http://store.3drobotics.com/products/ppm-encoder to convert the AR610 receiver output to a PPM input for the Pixhawk. Otherwise you will need to purchase a Spektrum Remote Receiver to attach directly to the Pixhawk Spektrum DSM input.
The Remote Receivers do not have as good a range as a full up receiver like the AR610.

Thanks TCIII.

So, just to make sure I’m getting it, my choices are to either:

a) Add a PPM encoder http://store.3drobotics.com/products/ppm-encoder which translates all 6 AR610 outputs to a single 3 pin PPM line, which is then connected to the RC IN input on the Pixhawk, or

b) Add the DSMX remote receiver https://www.spektrumrc.com/Products/Default.aspx?ProdID=SPM9645 which can connect directly to the SPKT/DSM port on the Pixhawk.

How is the Remote Receiver connected to the AR610 receiver? Is it a wireless connection?

You mentioned that the Remote Receiver doesn’t have the range of a full-up receiver. I’m missing something.
Doesn’t the AR610 pick up the transmitter, send it to the Remote Receiver, which connects to the Pixhawk? The AR610 and Remote Receiver are both on the vehicle, right?

Is there a Spektrum DSM receiver that’s compatible with my DX6i that outputs SPKT/DSM directly?

Or, is there a compatible (non-DSM) receiver with PPM encoder built-in that I could use?

I’m just trying to understand the options before I take a next step.

The Spektrum Remote Receiver connects directly to the Pixhawk’s DSM receiver connector instead of connecting to the AR610. You do not use the AR610 receiver when using the Remote Receiver.
Therefore if you want to use the AR610 you must use a PPM encoder and you can connect the Remote Receiver to the AR610 if it has a Remote Receiver connector. If you want to connect the Remote Receiver directly to the Pixhawk, then you do not need the AR610 or the PPM encoder.


That makes perfect sense. I was trying to make it too complicated.

I got tripped up because it’s called a “Remote Receiver” and not simply a “Receiver”. I thought it offered a way to remotely expand the received channels … or something (?)

Anyway, I think I’ve got it. I’m targeting indoor (large volume) operation so I prefer simple wiring to long distance. I have ordered a Spektrum Remote Receiver.

Thanks again for your help.
