The WS232UP USB HART Modem is a cutting-edge, USB-powered communication tool designed for professionals managing HART protocol devices. Featuring built-in 24V DC power and loop resistor, it supports all Windows versions from XP to 10 and offers three selectable modes for versatile field and desktop use. Its rugged aluminum casing ensures durability while maintaining a compact size smaller than a business card. Ideal for commissioning, servicing, and calibrating HART instruments, it comes with free software to streamline your workflow and eliminate the need for external power supplies.

## 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.

## 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
