The difference between DTU and wireless modem is that wireless modem is a physical tunnel to access network. It does not have operational system; thus working with PPP dial-up connections of PCs to get connected is required. In respect of DTU, it is a combination of embedded PC and wireless Modem, which is not only used as a modem but also have functions of data protocol conversion and transparent transmission.<\/p><p>DTU can connect to the industrial SCADA system directly. While in the mode of transparent transmission, the SCADA system is able to communicate by having an individual IP address. When DTU is used as a Modbus network bridge, DTU needs to have a static IP address. In this sense, data interaction with the SCADA system can be accomplished by the Modbus protocol. DTU supports smart protocol conversion to meet the communication demands between various protocols. So far, DTU has supported the conversion between Modbus TCP and Modbus RTU, enabling field devices to connect to the SCADA system. InDTU also supports user-defined login with TCP\/UDP, heartbeat monitoring, field identification and keeps link availability.<\/p><p>InDTU series is stable, reliable, easy to use with the features of flexible management and protocol transmission. Compared to other DTU products, InDTU has the following characteristics:<\/p><p>First, up to now, InDTU series has been sold up to millions of units around the world and certified by various countries, supporting all kinds of wireless networks across the globe with excellent level of failure and online rate, and its stability has been widely recognized by our customers. Then, a high reliable design, like embedded watchdog to ensure high device availability; multi-layer link detection mechanism, including PPP layer heartbeat, ICMP detection, TCP Keepalive and heartbeat on the application layer; automatically recovering network failure and maintaining &#8220;always online&#8221; wireless connection; dual SIM cards for redundant backup, all of these designs allow InDTU to remain \u201calways online\u201d connection and comprehensively improve its reliability.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e97deec elementor-widget elementor-widget-image\" data-id=\"e97deec\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.17.0 - 01-11-2023 *\/\n.elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=\".svg\"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}<\/style>\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"459\" height=\"214\" src=\"https:\/\/www.inhand.com\/wp-content\/uploads\/2023\/09\/DTU-1.jpeg\" class=\"attachment-large size-large wp-image-12261\" alt=\"\" srcset=\"https:\/\/www.inhand.com\/wp-content\/uploads\/2023\/09\/DTU-1.jpeg 459w, https:\/\/www.inhand.com\/wp-content\/uploads\/2023\/09\/DTU-1-300x140.jpeg 300w, https:\/\/www.inhand.com\/wp-content\/uploads\/2023\/09\/DTU-1-18x8.jpeg 18w\" sizes=\"(max-width: 459px) 100vw, 459px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-bd0467d e-con-full e-flex e-con e-child\" data-id=\"bd0467d\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;full&quot;,&quot;container_type&quot;:&quot;flex&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-fbc0833 elementor-widget elementor-widget-text-editor\" data-id=\"fbc0833\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>The network signal intensity of carriers varies from region to region. DTU is configured with dual SIM cards of different carriers, failover will take into action: it can automatically switch SIM 1 to the SIM 2 network in case the device goes offline.<\/p><p>Meanwhile, InDTU series has multiple management and configuration modes. For instance, local serial port settings, remote RTool &amp; SMS configuration and InHand Device Manager platform for remote centralized management, facilitating the implementations of customer projects and equipment maintenance. Additionally, InDTU adds the second serial port design in a creative way to make it has the function of remote maintenance of field terminal devices, which simplifies users to debug serial devices remotely. Because of dual serial ports design, while InDTU works stably, it can be maintained online, which can well balance its online rate at the same time. For example, the electric-power industry, DTU connects the terminal devices of DA on the DA terminal system, and its upper end is connected to the main station of the distribution center. If there is a need to change a configuration parameter of DTU, such as changing an upload time interval, the configuration can be completed without unplugging the serial port which connects the device, ensuring the online rate of the terminal devices.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-10145df elementor-widget elementor-widget-image\" data-id=\"10145df\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"359\" height=\"325\" src=\"https:\/\/www.inhand.com\/wp-content\/uploads\/2023\/09\/DTU-2.jpeg\" class=\"attachment-large size-large wp-image-12262\" alt=\"\" srcset=\"https:\/\/www.inhand.com\/wp-content\/uploads\/2023\/09\/DTU-2.jpeg 359w, https:\/\/www.inhand.com\/wp-content\/uploads\/2023\/09\/DTU-2-300x272.jpeg 300w, https:\/\/www.inhand.com\/wp-content\/uploads\/2023\/09\/DTU-2-13x12.jpeg 13w\" sizes=\"(max-width: 359px) 100vw, 359px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-979a35f e-con-full e-flex e-con e-child\" data-id=\"979a35f\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;full&quot;,&quot;container_type&quot;:&quot;flex&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-19b952a elementor-widget elementor-widget-text-editor\" data-id=\"19b952a\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Last but not the least, InDTU supports Intelligent Protocol, making networking more flexible and enabling it to adapt to more applications.
