NB-IoT LTE CatM1 RS232/RS485 TRB256 Gateway

Description

The TRB256 is a compact (83x25x74.2mm, approximately 165g) industrial LTE CatM1/NB-IoT gateway that supports the 450MHz band for improved coverage in harsh environments. It integrates RS232 and RS485 serial interfaces, a 10/100Mbps Ethernet port with auto-MDI/MDIX, terminal blocks for configurable digital I/O, and GNSS for tracking and geofencing.

It supports dual SIM with automatic failover and advanced management of SMS, roaming, band lock, and operator blacklists. 9 to 30V DC power supply with reverse polarity and transient protection, with idle power consumption of less than 1.2W.

The RutOS operating system provides static and dynamic routing, firewall, NAT, captive portal, multi-protocol VPN, DNS-over-HTTPS, QoS/SQM, and connection monitoring with automatic reboots. Compatible with IoT protocols such as MQTT, Modbus TCP, DNP3, and advanced SMS/USSD.

Remote management is possible via WebUI, SSH, SNMP, MQTT, JSON-RPC, FOTA, and RMS. Robust IP30 aluminum enclosure, mountable on DIN rails or flat surfaces. Operating temperature "40°C to +75°C, humidity up to 90% non-condensing.Main Features
