Emerson AMS Trex Device Communicator Features

A Rugged and Reliable Device Communicator

For a communicator to be useful in the field, it must be built to last and ready for anything. The Trex communicator is designed to withstand the harsh conditions in and around manufacturing facilities. The rugged device is easy to hold, yet designed to take the bumps and drops that come from normal use in the plant. In addition, the Trex communicator is protected against moisture and extreme temperatures, allowing you to work regardless of environmental conditions. The sturdy exterior is designed in accordance with Intrinsic Safety standards to limit the buildup of static electrical energy. Unlike consumer-grade mobile devices, the Trex communicator will withstand the abuse of a harsh field environment.

Designed based on user feedback and with field use in mind, the carrying case features an access window that allows you to use the communicator and contains pockets large enough to carry the charger, extra lead sets, or other tools you may need in the field.

Touchscreen Display for the Field

The Trex communicator features a 5.7" resistive touchscreen display for easy use with bulky work gloves. The adjustable backlit screen can be easily changed to save power or adapt to dark environments or bright sunlight, ensuring a crisp display that can always be read - no matter the external conditions.

An App for That

The Trex communicator includes Upgrade Studio, a PC application to help keep the Trex unit up-to-date with new software and apps.

With Upgrade Studio, add critical diagnostic tools to your toolkit and push them out to any number of Trex communicators. With multiple apps available and many more in development, Upgrade Studio will make the Trex communicator your go-anywhere, do-anything device:

  • Field Communicator - The Field Communicator app delivers a wide range of options for configuring and troubleshooting HART and FOUNDATION Fieldbus devices.
  • Loop Diagnostics - With the Loop Diagnostic app, you can power the loop in the field and also perform loop troubleshooting and checkouts. The app helps with loop characteristic validation and lets you isolate and troubleshoot wiring issues.
  • Fieldbus Diagnostics - The Fieldbus Diagnostics app gives you the necessary toolset for troubleshooting and validating Foundation Fieldbus segments.
  • WirelessHART Provisioning - The WirelessHART Provisioning app allows you to provision wireless networks in less time, with less chance of error and in a more secure fashion. The app can configure hundreds of devices with a push of a button, improving accuracy and allowing you to provision an entire network up to 6x faster.
  • Radar Master - The Radar Master app enables you to ensure the measurement and configuration accuracy of your Rosemount radar level transmitters by bringing the power of Radar Master software to the field. Use dynamic graphics to verify configurations while protecting the safety of your personnel and assets.
  • ValveLink Mobile - With Valvelink Mobile, you can analyze and review valve assembly condition and performance without affecting the process. Configuration and troubleshooting of digital valve controllers has never been more efficient.
  • Calculator - The Calculator app for AMS Trex includes a simple calculator, conversion calculator for base conversions, loop convertor/Ohm's law calculator, and unit converter for engineering units.
  • Trex Help - The Trex Help app offers a searchable help guide, putting key information on operation and troubleshooting at your fingertips.
  • PDF Viewer - Transfer PDF files to AMS Trex to easily access manuals, work processes, notes, and any other PDFs in the field.

Designed for Use

Designed for comfortable, one-handed, all-day operation in the field, the Trex communicator is packaged in an evenlybalanced form factor with a rugged hand strap so you can easily hold it, even when working in tight spaces. It comes standard with 32 GB of application memory, providing plenty of space to customize it with the apps of your choice. With built-in USB and Wi-Fi connectivity, you can move data to and from the communicator using the connectivity option that is most convenient. With numerous communication options, your communicator has never been more connected. The communicator's robust lithium-ion power module will keep it running for hours, well over a full shift, even when it is being used to power other devices in the field.
