Does anyone know which input wire the RPM output from the ULP 350iS should be connected to on the Dynon Skyview.  There are 4 choices for the input.  2 of the wires are standard voltage and 2 are low voltage.  I currently have it connected to the standard voltage and set at 2 impulses per revolution in the Dynon setup.  The Tach seems to work fine but jumps more than i'd expect.  I already have my panel closed, so before switch it to the low voltage input, I thought I'd see if anyone here knows specifically which Dynon input wire it should be connected to.

I would call Dynon directly. They have excellent customer support.

I guess I should have mentioned that I already called and talked to the technical advisor at both Dynon and ULpower.  Both said the same thing...I'm not familiar with Dynon/ULpower.  Ray recommended that I ask the ULpower forum to see if someone had figured it out.  

Wow, that's shocking to hear that five (or more years) after UL was introduced to the US experimental market, they still don't know how to make it work with Dynon.

Howdy Brian. I believe I connected wire 24 which is the left engine (omit right engine wire)and is low voltage. At least that is what I could glean out of Dynon's 528 page manual. Seems to give me a reasonable RPM readout. Tom
Correction: I connected the blue/white wire from the engine to the blue no. 34 wire on Dynon. Tom


I connected mine to Pin 34(Blue Wire) Low Volt RPM left connection and it works fine.  I also have 2 impulses per revolution setup.

Thanks for the replies.  Sounds like the consensus is to connect it to the low voltage input.  I'll switch it over and see if it fixes the jumpy needle.
