Autometer Datalogger

Hi Gang,

I want to connect a switch to one of these dataloggers, but the instruction manual doesn't give any clues as to how it should be wired. The datalogger's cables have three wires and I'm guessing I would use the red (probably +5VDC, may be +12VDC ) as the input to the switch and the green as the signal. My concern is if I do this without knowing for sure, I may destroy the datalogger if it can't accept the voltage coming back in the green wire.

Merry xmas to you all from New Zealand,
Paul.

 

what will the switch do?? if is going to work as on/off the red is power on the autometer..green is signal black is ground..Dave...p.s. we run the autometer
also 5 volt

 

Hi Dave,

It's just a WOT switch, but I also want to send a signal to the DL from the transbrake relay/switch so I can measure the car's reaction vs throttle application. So, the green can accept 5 volts from the red wire via a switch? Do you know if it can accept 12 volts? I could then run a wire from the transbrake relay (or anything else I want to monitor that uses 12 volts) directly into the DL.

Thanks for your help,
Paul.

 

no 12 volts<<<<<<<<<<.and what the wires do is its like a flo meter it takes the 5 volts to power it up and the green and black works like an on /off switch..just remember green is the signal wire. In my opinion I don't think it will work as you are telling me! if you need Doug Lemons # at autometer I can give it to you, he is real cool about making mods to the computer he helped me with a few (strange) things I was doing..Dave

 

Ok, no 12 volts. There must be some way of putting a simple on/off signal into these things without letting the smoke out Yes, please, if you could give me Doug's number I'll give him a call and have a good yak with him. Thanks for your help.
