We still receive many inquiries from customers about TREX, but TREX will gradually exit the market. Because Emerson will officially release AMS Trex in October 2025 \u2122 The second-generation device communicator, as a comprehensive replacement model for the first generation TREX. TREX will gradually exit the market, and manufacturers will gradually clear TREX inventory. They will now begin selling upgraded TREX2 second-generation products. The new product TREX2 continues the explosion-proof shell and 5.7-inch glove touch screen appearance, but the internal platform and functions have undergone significant innovations.<\/p><\/div>\n\n\n\n

From the above upgrade schedule, we can see that TREX has been released for 10 years. Emerson has now launched its latest product TREX2. TREX2 will be equipped with a brand new Android 14 system, which is convenient for our usage habits. The system is as smooth as our phones and the hype logic is more reasonable. The chip has also been upgraded with stronger performance. The memory has also expanded by 8 times, improving the speed of information and data processing.<\/p>\n\n\n\n

For many users who are already accustomed to using TREX, let’s take a look at the latest TREX2 upgrades and differences<\/span><\/h6>\n\n\n\n

Suggestions on TRER on-site replacement and procurement points<\/span><\/strong>
Current situation of existing first generation TREX
The original factory still provides maintenance support for a period of time, but new features and new DD device drivers will be prioritized for TREX2 in the long term; It is recommended to directly choose TREX2 for long-term procurement of new projects.
Compatibility of accessories for TREX1 and 2 generations
The protective cover, test probe, and charger cannot be directly used interchangeably; Modification of battery module structure. TREX2 is equivalent to a fully upgraded product with independent hardware development, and many spare parts are incompatible.
Software synchronization
The new version of PC Upgrade Studio supports both the first generation TREX and TREX2, but their firmware packages cannot be flashed to each other.<\/p>\n\n\n\n

If you are interested in TREX2 products, please feel free to inquire. We have excellent delivery times and prices. Here are the recent photos of TREX2 that have arrived<\/span><\/strong><\/p>\n\n\n\n

At the same time, we also have some TREX1 storage products, and we welcome your inquiries<\/p>\n\n\n\n
