LM-3S-G Chuff Input Install help (SOLVED)

(1/1)

zr1rob:
Can anyone help me to get my LM-3S-G chuff input wired correctly?

All I know is that the 'input' (assume purple wire) is where a signal is received from something. Again, I'm assuming I can use 4 small magnets on the inside surface of a driver wheel, triggering a reed switch. But what then?

Should I feed +5V to one side of the switch, and send the other side to the purple wire? Or ground one side of the reed switch with the other end going to the purple wire?

Any help would be greatly appreciated, thanks Rob


SOLUTION: From the "What's New Page" at Ring Eng: https://www.ringengineering.com/WhatsNew.htm

June 2021
New LM-3S-G Program Rev 2.50 and HC-2b Rev 2.23
Adds the ability to choose the input wire for Chuff Trigger Sync on LM-3S-G modules!
IMPORTANT:  You must update your HC-2b program and your LM-3S-G program to select the input wire for chuff sync.
IMPORTANT:  You wire one side of the reed switch to +5V and the other side of the reed switch to the input wire on the LM-3S-G module.
