4G Industrial Router
The industrial-grade 4G cellular router R40 offers three standard RJ45 10/100Mbps LAN ports and one standard RJ45 10/100Mbps WAN port, which can also function as a LAN port. It optionally supports IEEE 802.3af/at-compliant PoE PSE functionality, providing stable power to on-site network devices and reducing wiring costs.
The industrial cellular router R40 supports WiFi and can operate in both STA and AP modes, allowing wireless devices to quickly connect to the network. It features dual SIM card slots and supports automatic switching between wired and wireless networks, ensuring a reliable network connection.
The cellular router R40 supports VPN protocols such as L2TP, IPSEC, and OPENVPN, ensuring secure data communication.
Built with an independent hardware watchdog, the industrial-grade 4G cellular router R40 has undergone professional electrical performance design and high/low-temperature testing, ensuring stable operation even in harsh environments.
