Overview
Dual-port MiniLink DTU that maps two RS232/RS485 channels to 10/100M Ethernet with dual socket contexts, Modbus RTU/TCP gateway, and browser-based provisioning for redundant control cabinets.
Key Features
Model: Y202-R
Key Features
Dual RS485/RS232 ports share a 10/100M Ethernet uplink with link aggregation
Four concurrent TCP/UDP/HTTP/MQTT tunnels plus Modbus polling and JSON push
Web/CLI/SMS management with DHCP, DNS, SNMP, and NTP sync
