    EMS voltmeter pin 1 values

    Hi, I have connected the EMS DB37 pin 1 (red wire) with a VPX installation for the volt meter 1 reading. The location where I mounted the pin 1 is with a ring terminal on the powerlug of the VPX (so the entry of the bat+ right at the vpx). Pin 3 is connected to GND block of the aircraft Is it...

    UMA tachmeter question

    For those reading this thread. I had already reached out to UMA as well. Here is the answer from UMA tech support. " Hi. The shield wire is connected internally with the blue-white wire (GND). You don't have to connect the shield anywhere, just cut it off. Mag pickup works from 5-16VDC and 12V...

    UMA tachmeter question

    aah yes... should have though of that. as you see... electrically disabled :) Got my panel all wired up and I'm happy I came this far without smoke. some more EMS sensors to install but getting near the end.

    UMA tachmeter question

    Thanks for the feedback @benapilot. That clarifies things. I'll use the power wire directly from vpx and pin 32 for the signal. I had seen that drawing indeed. I have a 4 cyl IO360 superior engine. so according to the drawing my pulse/rev setting should be 1. I have Champion slick mags model...

    UMA tachmeter question

    Hi all, My electrical skills are pretty close to non-existent, so please be gentle with the responses. Thank God for VPX and Dynon. I am installing a T1A9-1 UMA tachometer and have a few questions related to the installation. I searched and read through other tachometer topics but couldn’t...

    A VPX alternator question

    clear explanation, thank you. so I take away from this that your 2 switches for master and alt work independently from each other and can be just simple SPST switches and both can be on regardless of the position of the other. Off course both is the normal operation mode but in case of problems...

    A VPX alternator question

    The last response of n144sh is what I had in mind having a double switch to make sure there are no surge powers. but I read also in the VPX manual that the VPX field wire does protect against over voltage. That's what keeps me unsure how to wire. The vpx manual looks pretty clear on having to...

    A VPX alternator question

    This may seems like a trivial question but I didn't find any answer in manuals. it's vpx related and not directly Skyview. My skyview is running well so far and I'm very happy with it. My excuses upfront but I'm not strong in electrics stuff. I've been able to get my vpx and basic circuits...

    Starter Annunciator warning

    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 ?

    Starter Annunciator warning

    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.

    Starter Annunciator warning

    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

    Starter Annunciator warning

    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...

    Broken line resistor

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

    Broken line resistor

    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...

    drill size bellcranks

    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...

    SV-HARNESS-INT question

    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...

    SV-HARNESS-INT question

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

    SV-HARNESS-INT question

    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 ***

    SV-HARNESS-INT question

    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...

    SV-HARNESS-INT question

    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...
