Will this work with windows 11 ?

As we only use Windows 10 on our computers here at work, I can only vouch for that but, I believe it will work with Windows 11 because the drivers I found on the internet say that it's compatible with 11 as well. Good luck

Works when just connected to the transmitter. loop goes over range when transmitter & modem are connected to plc analog input. switch has no affect.

When placed in series, the modem should only be a way to inject a change in the transmitter...I've never seen it cause an over range in the loop. I'd be curious to see that in action

Will this work with Emerson Instrument inpector?

It should work with any program that uses HART protocol

Did anyone get this to work without breaking the loop?

It needs to go in series with the device to be part of the circuit so not breaking the loop won't work. Be sure to set the switch on the side to the 270 Ohm setting as well
