## Overview

The H&H WS232UP USB HART Modem by Daphne's Headcovers is a compact, rugged interface designed for seamless PC communication with HART devices. Featuring built-in 24V DC power and loop resistor, it supports three selectable modes to power and configure any 2-wire HART transmitter. Compatible with Windows XP to 10, it offers plug-and-play USB connectivity with LED indicators for real-time communication status, making it an essential tool for commissioning, servicing, and calibrating HART instruments in the field or lab.

## Description

Applications: 1. Install the USB driver software. You can update or download this driver anytime from internet; 2. Plug the USB cable to your PC, the yellow 'POWER' LED will illuminate; 3. Slide-switch to select operating mode, and connect the test cable and HART device according to the following pictures: 11 * 24VDC/270Ω Mode: The red “24VDC” LED will illuminate. This mode can power all 2-wire HART device, internal loop resistor is available. Does not need external power and loop resistor. 22 * Normal Mode: The red '24VDC' LED will not illuminate. This mode is very typical for HART MODEM, need external power and loop resistor 250Ω~1000Ω. 33 * 270Ω Mode: 1. The red '24VDC' LED will not illuminate. This mode need external power, does not need loop resistor; 2. Run the HART application software to configure your HART device. The red and blue bi-color “Tx/Rx” LED will blink alternately when the communication is good between PC and HART device( Tx-RED, Rx-Blue). 3. If you finish your operating, Please close your HART software, then pull out the USB cable and disconnect the test cable. 44 Packing Lists: 1 x WS232UP Unit; 1 x USB Date Cable; 1 x Carry Pouch; 1 x CD Driver.

Review: Included software is just a bunch of freeware programs that can be downloaded from the various manufacturers. I work mostly on Rosemount stuff, and none of the included programs allow me to calibrate them unless I purchase an expensive license. This modem also draws a bit of current from the 4-20mA loop, so when I connect to a transmitter that's in service the loop current jumps by about 2.7mA, no matter what setting the switch is on. Tech support and instructions are basically non existent, and good luck getting a refund if it doesn't work for you and your application. I was able to get it mostly working using a paid android app called AndroHART, but it only allows a few basic things. For instance, you can zero a transmitter but not calibrate the URV. This app also doesn't do any sort of live view, so you have to poll the transmitter constantly to see updated values. This HART modem does sort of work for some situations though, but not as advertised with the software that is included.
Review: Works great and extremely easy set up. No issues with drivers, just download PactWare and the proper DTM for your device and it connects right away. Powered up a few transmitters right from my USB port, no issues there either.

## Questions & Answers

**Q: Will this work with windows 11 ?**
A: 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

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

**Q: Will this work with Emerson Instrument inpector?**
A: It should work with any program that uses HART protocol

**Q: Did anyone get this to work without breaking the loop?**
A: 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
