Many people are confused about the difference between DTU and gateway devices. Today, I’ll explain this topic clearly, starting with what a DTU is. DTUs are widely used in the market across various scenarios including agriculture, industry, water conservancy systems, and many other applications. What is a DTU? A DTU (Data Transfer Unit) primarily functions to transmit data transparently to cloud platforms. This transparent transmission means that if you have data from RS-485 or RS-232 serial interfaces at your field site, it’s essentially like extending a virtual cable to your platform remotely. For example, when I transparently transmit this data to the cloud platform via wireless methods, the cloud platform […]<\/p>\n","protected":false},"author":1,"featured_media":3789,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"themepark_post_bcolor":"#f5f5f5","themepark_post_width":"1022px","themepark_post_img":"","themepark_post_img_po":"left","themepark_post_img_re":false,"themepark_post_img_cover":false,"themepark_post_img_fixed":false,"themepark_post_hide_title":false,"themepark_post_main_b":"","themepark_post_main_p":100,"themepark_paddingblock":false,"footnotes":""},"categories":[16],"tags":[],"class_list":["post-3785","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"metadata":{"classic-editor-remember":["classic-editor"],"_edit_lock":["1750041778:1"],"_edit_last":["1"],"_thumbnail_id":["3789"],"themepark_seo_title":["Understanding the Difference Between Data Transfer Unit and Gateway in One Article"],"themepark_seo_description":["Many people are confused about the difference between DTU and gateway devices.
