[App_rpt-users] Correct Wiring For The URIx Diagnostic Dongle

[Doug Crompton]

Also note you do not need external 12V for the additional op-amp. It will work on 5V from the URI as long as you do not exceed the P-P output for that voltage which would probably be somewhere around 2V P-P. You obviously could get more swing running it on 12V but if you don't need it, it works fine on 5V.

Pin 23-24 is correct. This has been
updated on the website, as you've indicated, and told it is updated in newer
uridiag.

 

Thanks,

Hello Again,



 





To get correct results - doesn't it make more sense to wire up this:

>From the above - how does AIN (pin 24) work?
