OEM panel tactics, remove or multimeter

[kurt-olsson]

Hi.

I am starting to interface the wing anti ice panel.

I have two thoughts on interfacing.

1: read the schematics (which i find really difficult due to lack of knowledge) and connect my cables to the pin out canon plug. And the teensy stuff outside the panel. If you can remove the chassi and get access to the switches with multimeter it will be really easy to interface without removing anything.

2: remove all unnessesary cables such as relays and cards etc and the build the teensy inside the panel. This way i can easily use multimeter to find which switch goes to which cable. Bad think about this is that its kind of a crime to redo any of this master original installment.


What approach did you select, i know from Robs videos that he is going for the schematis and connects the pin, is this the "main" way to do it?


By removing the chassi i have already mapped every switch without any changes of the cables, think i will go for this approach.

What is the partnumber for the cannon plug female connector? Is it the same connector on all panels?

I changed tactics and glad I did.  I went Teensy and my Sim Interface board per module.  You one usb and one 3 pin connector per module.  28V, GND, 5V  (backlighting)   Code is small and easy to update if needed, Wire mess greatly reduced, easy to pull for maint if needed in future. 

Gut internals, use PWM and ULN2803 on Korrys for the valve open/closed lighting, Switches direct to Teensy.  Very easy and tidy

I did what Rob did for everything I installed after discovering Teensy. My Avidyne autopilot has just 1 cable coming out the back. If I had to run wires everywhere for a different interface platform, it would have been ugly.

Thanks Rob and Ray!

It brakes my heart to remove the "junk" i dont need. But this part will never fly so it will be used for sim the rest of its life. So its better to make a good architecture around the sim instead.

I was very keen to the idea of having everything inside the panel and just like yours a 28v,5v and USB connector. Maybe even do some custom "connector box" that i will use for all my panels.

Because i know you use OEM i will do the same as you, just becuase i know you have lots of experience with OEM and i don´t have to rebuild after thinking it will be too much wiremess if i go with the interface outside the panels.

I also think the cannon plug connectors will be pretty costly and hard to get, and they are a mess to solder against...


I can also use lots of existing cables for other applications, they are of great quality! For my Motors etc...


Thanks again!

OEM FTW! =)

As a home studio guy i think i will go for the XLR connectors for 28,5 and ground connection, you cant insert it in a wrong way and then blow your backlight or shortcircuit the thing.

then a usb panel mount beside that. That will be extremely superclean! =)
