encoding altimeter pinout?
Hi Everyone,
I have an Aero Mechanism 8140B-20 Altimeter/Encoder. Does anyone happen to have a pinout for this model? Or any ideas on where to find one? The google search turned up an Aero Mechanism CNC, but they are not the right guys. tia Bill |

I don't know if that necessarily means that they supply info from it... |

It might be that there is a D output... for you high flyers. There is one pin, G, unaccounted for on the list above. I'm not sure all Aeromechanisms would have this. I believe that one of the grounds is a ground for the LEDs and one is for the output phototransistors. I think the jumper from M-N adjusts the current for 14v. I'd guess that you would leave it out for 28v. You could measure between them and see if it was a few hundred ohms... that would confirm the theory. That's the best I can do. Bill Hale |
