Joining two wires to a serial PIN

[bkthomps]

Does anyone have any documented pictures/method of joining two wires to a single DB pin?

I am thinking of stripping insulation back on the wire that has the pin crimped on it, then wrapping the wire around it, solder, then heat shrink- is that right? is there a recommended distance from the actual pin that is normal/standard for this?

anyone have pics??

Not exactly what you were looking for, but very similiar. Solder sleeves are your friend. You can get them from SteinAir and ACS. Homedepot also sells them, but typically only stock larger sizes. The photo is off Stein's web site.

I typcially use a couple inch pigtail so that the connection is outside the connector. Otherwise the bulk from the splice may not fit inside the shell.

What is shown is a pigtail breaking out the shield to be connected to a ground connector.

I've used the solder sleeves to connect 2,3,4, etc wires together. It's heat shrink and solder that can be applied in a single step with a heat gun. You can get multiple sizes to accomodate the various guage and quantities of wires.

these are all awesome suggestions, just trying to twist my brain around what i am trying to do which is two wires to a single pin, not two pins to a single wire

(audio left/right from each dynon screen to audio panel single input L/R)

I was able to crimp two #24 wires in one pin, and maybe a #22 and #24 in one pin

Why not simply splice the two wires to one and then the one to the pin/socket? This would for the case where the two wires are too large to be twisted together and then inserted into the pin/socket.

One wire into one pin as a pigtail, then "Y" it off to two wires via a solder splice outside of the connector's shell.

Hi Brian,

I'm not sure how the skyview audio out is setup but combining two audio sources should usually be done with at least a passive mixer to avoid overloading the input on your intercom/audio-panel. If it's stereo to stereo you can just put a 10k resistor inline with both your 2 left and 2 right inputs before you mix them (4 total resistors).

I suspect that, if you are connecting your sky-views (or D1x0 units) together then you only need the audio output from one of them. You might want to check with dynon support on this.

dynon states to connect the screen 1 L and screen 2 L together, same with R, they state if your audio panel is mono, then connect L+L+R+R all together to the single mono input, both screens must be connected to tolerate a single screen failure

Cool - I just read 4-12 of the skyview manual and it sounds like that's really what they want you to do. If you get distortion the level's are probably just a bit too high. I wonder if fail-over also handles fail-over of the sound or if it always sends from both.

I can't justify a skyview yet - I'm having too much fun hacking my D180.
