Thanks anyway. I appreciate your offer, but I don't think you would be able to help me.

Everything in your post is only true if you wire it up the way it requires, to wit, with SPDT COM1/COM2 selector switches. The pinouts on the SV-INTERCOM-2S DB25 Connector are designed and implemented to conform to that design. The manual even has a diagram (Figure 10), depicting it, as both of...

Rhino, Thanks for your insight, I did see that entry in the manual. However, my issue is a bit more complex. That paragraph is about what shows up on your headphones, and assumes that you wire everything in accordance with whatever scenario that paragraph was written to address (Single COM...

I apologize for my inability to get this straight. I have had several phone conversations about this with Dynon tech representatives, but when I try to match up what I took away from those conversationls with the documentation in the installation manual, I keep getting mixed up. Would a Dynon...

Yes, in hindsight, I understand.

I understand. Given that perspective, I suppose blind adherance to convention would work, at least as long as you only execute tasks that also conform to the convention. What I had to do was figure out how to add a diode to a circuit that controls a starter solenoid. The instructions first...

The inconsistency i was talking about is the convention that the black stripe on a diode is on the end towards which the current flows. If he/she understands that the current flows in the direction that the electrons are moving, (and is nit aware of this inconsistency), then he or she will...

If the installer, (taught in a confusing inconsistent way), connects the cathode to the positive terminal, then they are NOT connected the same.

Unless you connect them the opposite way because of how or what you were taught. Inconsistencies create misunderstanding and opportunities for error.

As I mentioned in my question, I understand that the actual flow of the electrons is opposite the direction from higher voltage to lower voltage on any two points in the circuit. i.e., Current is considered to flow from positive to negative, even though the electrons are actually moving opposite...

As I thought, Thanks so much for confirming. I can imagine I am not the only one for whom that inconsistency has been the cause of confusion!

The standard for signal pins, (like the PTT pin) on COM transceivers, which are inputs, is that the switch that opens and closes the circuit, (e. g. the normally open [NO] SPST PTT pushbutton on the control stick or yoke), is that the voltage polarity of the PTT pin/wire coming out of the...

Thanks for the update! I, for one, appreciate the update, (and more frequent updates would be appreciated even more)!

Hah! that would be an error of 33,480,000 miles. That could put you somewhere around the orbit of Venus...

I had sorta given ip on I had sorta given up on this point, but seeing ve0kog's post made me want to add my support. I agree with the safety implications of this change. Having an accurate aural indication of aircraft AOA without needing to divert your attention away from other critical inputs...
