Automatic uplink switching with default priority WAN, then Wi-Fi, then 4G Cat.4
Y212-GWR 4G, Wi-Fi and Ethernet Serial Gateway Router
Tri-Mode Industrial Router
Y212-GWR combines 4G Cat.4, Wi-Fi and Ethernet failover with RS232/RS485 access, a fixed LAN port and a second port switchable between WAN and LAN.
Key Features
Two 10/100 Mbps RJ45 ports: port 1 is fixed LAN; port 2 defaults to WAN and can switch to LAN
RS232/RS485 main serial interface, two configurable digital I/O, IO3 function pin and optional TTL secondary UART
2.4 GHz Wi-Fi AP or STA operation, 6–26 VDC input, remote AT access and OTA firmware upgrades
