Features
Core Advantages
5G/4G/3G/2G & Dual SIM/eSIM
Supports diverse cellular network access (2G/3G/4G/5G), with 4G LTE options including Cat1/Cat4/Cat6, and 5G NR supporting eMBB/RedCap. Equipped with dual SIM and dual eSIM capabilities to enable flexible switching and link backup.
100Mbps Ethernet Interface & Wi-Fi
Equipped with a 100Mbps Ethernet port supporting WAN/LAN auto-sensing and Wi-Fi 4 (2.4 GHz) wireless access, it combines stable wired transmission with convenient wireless connectivity, meeting the needs for industrial equipment networking, data transmission, and on-site network deployment.
Integrated Serial & GPIO Interfaces
An integrated design featuring serial ports (1*RS232 + 2*RS485) and 4*GPIO interfaces facilitates the connection of industrial equipment and enables control of digital (on/off) inputs and outputs.
TesproOS System & Remote O&M
Equipped with the proprietary TesproOS operating system and a visual web-based management dashboard, it enables full-lifecycle device management. It supports real-time cluster status monitoring, remote batch parameter configuration, log diagnostics, and cloud-based OTA firmware upgrades; combined with multi-layer VPN encryption, it facilitates efficient O&M without the need for on-site visits.
Rich Protocol Ecosystem
Integrates northbound cloud protocols (MQTT/OPC UA), industrial fieldbuses (Modbus/ProfiNet), and power/energy protocols (DLT645/IEC61850). Combined with OpenVPN/IPSec encryption and rapid custom protocol development, it simplifies device onboarding for plug-and-play deployment and accelerates OT-IT data convergence.
Excellent Weather Resistance
Supporting a wide operating temperature range of -40°C to +75°C and non-condensing humidity levels of 5% to 95% RH, alongside an IP30 protection rating, it reliably handles complex and harsh industrial environments—including high altitudes, high temperatures, and high pressures—to ensure stable equipment operation.
