It works and it's cheap.
Used with Pactware and with DeviceCare SF100, works great, provided 24.4V to the device, as long as you have the DTMs it works great! Tested a few different ways, as a primary master and by itself no issues, as a secondary master connected with a PLC as the primary had a few drops while polling, which is no different from any other hart communicator out there that costs much much more!!! And I love being able to se the TX and RX blinks!

worked with pactware
The disk I received was blank. But windows 10 loaded usb and it work with pactware. I don't know how you would use it wifi. But for me it was cheap solution.

Very satisfied
I used the included modem driver and used Devcom2000 with no issues. Makes it quite a bit easier when setting these up on the bench. It has an option to power the transmitters and has the 250resistor built in. Software that comes with it is harder to use but since it works with devcom2000 still giving 5 stars. Definitely worth the money.

Works as advertised.
There are a lot of reviews for this device or ones that look awfully similar and I couldn’t get a clear answer as to whether this works or not. I was able to get it to work and have created an Instrucatable documenting the process. Search for “ SM100-C(III) HART Modem Configuration for Industrial Instrument Communication” and you’ll find it.

Doesn’t work, not worth the case it was shipped in!
