The AMS Trex Device Communicator expands the long line of Emerson handheld devices while adding new capabilities that adapt it to consumer expectations for mobile device functionality. Technicians armed with a Trex communicator won’t waste time bringing devices back to the shop for analysis or reconfiguration. AMS Trex is delivered with a complete, pre-installed DD library for over 2,000 HART and Foundation Fieldbus devices so users can easily diagnose device problems in the field. Simple issues can be addressed on the spot, avoiding unnecessary, and potentially destructive, invasive physical investigation of the problem. Technicians need powerful and portable diagnostic tools so they can identify and troubleshoot device issues to minimize process upsets. With a Trex communicator in hand, you can properly diagnose device issues in the field. With the right handheld, maintenance teams will experience significant savings in work hours and peace of mind knowing that problems will be fixed quickly and properly the first time. Once changes are made in the field, AMS Trex will automatically synchronize the information with the AMS Device Manager database via Wi-Fi or USB connection.

The 709H adds HART communications and supports a select set of the HART universal and common practice commands. This makes the 709H unique as both an affordable, compact loop calibrator and powerful HART communication troubleshooting tool. In the communicator mode the user will be able to read basic device information, perform diagnostic tests, and trim the mA output on most HART enabled transmitters. In the past, this could only be done with a dedicated communicator, a high-end multifunction calibrator, or a laptop computer with HART modem. 709H will allow virtually any technician to service and support HART devices.
