Milesight UR32 | Industrial 4G LTE Cellular Router

The Milesight UR32 is a carrier-grade industrial 4G LTE cellular router engineered to deliver tenacious internet access in the most challenging environments. Built on an NXP industrial-grade processor in an IP30 hardened enclosure, with a wide −40 °C to +70 °C range and 9–48 V DC supply, it keeps mission-critical sites connected where consumer hardware can't cope.

It combines dual-SIM 4G/3G cellular, dual Ethernet, and optional Wi-Fi with rich field interfaces — RS232/RS485 serial and Digital I/O — for scaling M2M and IoT applications. Automatic failover across Ethernet, cellular (dual SIM), and Wi-Fi, plus a full VPN suite and remote management via MilesightVPN and DeviceHub, make it a dependable network backbone.

Core Capabilities

Dual-SIM 4G LTE Cat 4 Up to 150 Mbps downlink / 50 Mbps uplink over 4G LTE Cat 4 (WCDMA/GSM fallback), with two Mini-SIM slots for dual-SIM backup and uninterrupted connectivity. Rich Field Interfaces RS232 with optional RS485 (included on these models), Digital Input/Output, and 2× fast Ethernet. Serial supports Modbus Server/Client, Modbus Gateway (RTU↔TCP), and DLMS for industrial integration. Multi-WAN & Optional Wi-Fi / GPS Automatic failover/failback across Ethernet, cellular (dual SIM), and Wi-Fi. Optional 802.11 b/g/n Wi-Fi (Client/AP, up to 15 users) and GNSS (GPS/GLONASS/BDS/Galileo/QZSS) by model. VPN, Security & Remote Mgmt Multiple VPN tunnels (IPsec, OpenVPN, GRE, L2TP, PPTP, DMVPN), SPI firewall with DoS/DDoS protection, AAA authentication, an embedded watchdog, and remote management via MilesightVPN and DeviceHub.

Typical Applications

• Industrial Automation: Bridge serial PLCs and Modbus equipment to the cloud with RS232/RS485 and Modbus gateway functionality. • Smart Utilities & Metering: Reliable dual-SIM backhaul with DLMS support for energy, water, and power-distribution networks. • Fleet & Asset Tracking: Use the GNSS model for location-aware deployments in transport and logistics. • Remote Sites & Digital I/O: Monitor and control equipment via Digital Input/Output with alerts over SMS, email, MQTT, or Modbus.

Choosing Your Variant

Model	Key Options	Best For
UR32-L04EU-W-485	Wi-Fi + RS485	Sites needing local Wi-Fi access alongside cellular.
UR32-L04EU-G-485	GNSS/GPS + RS485	Location-aware / tracking deployments.
UR32-L04EU-P-W-485	PoE + Wi-Fi + RS485	Powering a camera/AP over Ethernet plus Wi-Fi.

All variants are EU 4G (LTE Cat 4) with RS232/RS485, DI/DO, dual SIM, and 2× Ethernet. PoE output requires a 48 V DC supply.

Technical Integration

The UR32 bridges field equipment to the cloud with rich interfaces and protocols:

• Connectivity: 4G LTE Cat 4 (WCDMA/GSM fallback) with dual Mini-SIM, plus 2× 10/100 Ethernet; optional Wi-Fi (802.11 b/g/n) and GNSS by model. • Field I/O: 1× RS232 with RS485 (included on these models) and Digital I/O (dry-contact input). • Serial modes: Transparent TCP/UDP/MQTT, Modbus Server/Client, Modbus Gateway (RTU↔TCP), and DLMS Client. • Protocols & reliability: IPv4/IPv6, SNMP, MQTT/MQTTS, TR069, VRRP, and dual-SIM backup. • Power & mounting: 9–48 V DC (48 V for PoE output); IP30; desktop, wall, or DIN-rail. • Setup help: Talk to the shopioT technical team for SIM/APN, serial/Modbus, or VPN setup.
