YJINGRUIUSB Hart Modem USB to Hart Protocol Modem Hart Transmitter for Rosemount/ABB/Vega/E H/ETC Hart Protocol Device Adapt to Windows XP/7/8/10 with Built-in Loop Resistor

At first I had some issues with getting this set up. I couldn't find an interface software to use with this and my devices. But I wound up purchasing some software called Devcom 2000 and this works very well with this Hart Modem.

I use this item in the oil & gas industry. I understand the price point infers less quality than like products. However, this item is not even toy quality. The connection cable is coming out of the y connector. The signal when hooked into the hart loop is all over the place. The reading back at the hmi is 2mA high. Over all it’s not accurate enough to be safe when on a critical process. Get what you pay for.

This product was helpful for out in the field. Only set back is that you have to drag your laptop out for field work. It was delivered on time which was huge because I needed on that date to meet deadline.

Have used this with a couple of different devices. Works as expected. Documentation non existent

While other handheld Hart protocol devices were costing in the range of a thousand dollars or more, this little device did an excellent job of communicating with our oxygen probe. Plug and play, download pactware and flawless connection.

Works Great! Just make sure to download the driver - link posted in the questions above. Used this to set up instruments from Vega, Rosemount, E&H, ETC. Works with Pactware.

Could not get this to interface with my computer (Windows 10 laptop). It did power up, but nothing I tried could get it to talk to my software (PACTWare)

the zipper of the case is damaged, if you close fast it it don't close, otherwise the modem works correctly.
