I was wondering how VPX knows the RPM data of the engine. Is this information transferred to the VPX over the EFIS serial line via the readings on the EMS module ?

thanks for clarifying the link with the 500 rpm on the engine. I hadn't thought of that and it makes sense, off course. Will move on with building.

That's indeed what I did. Is there any way I can test it other then seeing the VX Starter widget showing "ON" if it keeps stuck

Hi Folks, I have wired my ACS A-510-2 starter switch to the VPX as prescribed PWR pin to jumper J10-1 and the starter annunciator with a 1K 1W resistor in line to pin J2-11 When checking in VPX configurator, I can see the starter on message in device status going to ON when cranking to the...

ah super, I missed that paragraph in the enthusiasm and focusing on the schematic. I'll go for the closest 5.1K. Many thanks

I have a small question on wiring the optional Broken-Line detection for the autopilot disconnect switch on my G407 stick. My appologies upfront for the stupid question, I'm not very skilled in electronics or electricity. Although so far I have been lucky not to see any smoke. The manual...

hi Everyone, I have a small question (probably stupid). I'm wondering why the manual on the install kits of roll and pitch servo tell you to drill a #11 size hole in the bellcranks. Is there a reason why this is #11 ? In the entire aircraft I have always drilled and reamed #12 holes for AN3...

I purchased the intercom harnass and will reply my own initial question. In order to find out more on the internals of the wiring I opened up the shrink tube at the intercom connector and looked what was found underneath. In short: the purchased harnass comes with the ground wires and shields...

you are right, I forgot to update the text on the second line to copilot mic instead of phones. updated it in this picture

Thanks a lot for all the answers, this together lead me to a solution which leads to how I will wire it as in the image below. hope my findings also help other less experienced builders (like myself) with the same question. open for comments if something looks wrong ** deleted original picture ***

I understood indeed the part of a solder sleeve and a single wire pigtail as a connection point to facilitate. what I can't physically picture yet is the point in the manual where it says to wind the 6 or even 9 wires together in a single joint to join pin 1 of the intercom. the point where you...

does someone have an example that shows how you do that (bringing all these shields together ? the manual says to wind all cables together. That seems like a lot of cables to go to one single pin point. How do you manage that in or so close to the connector of the intercom. If someone could...

Hi all, I am planning on buying the SV-HARNESS-INT harnass for the intercom as it seems too many wires to handle conveniently by myself. The manual of the intercom states about ground loops and shield grounding : Because other electrical loads can cause large current flows in a ground path...

thanks a lot for the clear explanation. I will proceed in that way as I have the 3 conductors.

I did buy the backup battery so J23 is not a good option then. J24 goes on GND of the the gps so that leaves 21 and 22 if I would follow the recommendations in the VPX manual. Did I understand your first answer on ground loop well that it's probably better to solder the vpx J1-21 gnd line...
