X10+v2 and an FrSky SBUS Receiver
#1
Jim,

I hope this note finds you and your family well.

I did an experiment where I used an FrSky "SBUS output" receiver connected to an X10+v2.  I configured the X10+v2 to accept an SBUS input.  Then I bound the receiver to my Taranis using its internal radio's D16 protocol.  There was no XPS transmitter module involved in this test.

There were interesting results:

With the transmitter, X10+v2, and receiver powered up, the X10+v2 showed a steady green led which indicated a good connection to the receiver (and transmitter).

An old Futaba S148 servo ran when connected to the X10+v2, but it ran a little notchy.  It also vibrated and hummed while sitting idle.  I reckoned that being a 25-year old analog servo, it perhaps had a problem with the SBUS frame rate.

Then I tried a relatively modern digital servo, an MKS DS95, and it worked very fast and very smoothly and without any vibration or humming.

Can you speculate why the S148 servo did not work well with the setup?

Thank you,

Paul

You are correct that the frame rate that SBUS uses is too fast for analog servos. The X16 and X24 both have an option to reduce the frame rate internally on a per servo basis. So you can use the S148 at 1/2 the frame rate while the other servos operate at the normal frame rate. The new V3 X10+ will also have this feature.

Thanks Jim. Look forward to flying your new creations. Paul
