Serial Gateway
Serial to 4G / WiFi / Ethernet / LoRa Gateway
The Y201, Y202, Y204 and Y208 Serial Gateway families connect RS232, RS485 or TTL devices to 4G LTE, Wi-Fi, Ethernet or LoRa networks. Models provide 1, 2, 4 or 8 serial ports and support transparent TCP/UDP, Modbus RTU-to-TCP and MQTT/HTTP data transmission.
- Support RS232 / RS485 / TTL
- Supports Modbus TCP / RTU
- Support TCP / UDP / MQTT / HTTP
Model Comparison
| Model | Uplink | Serial Ports | Interfaces | Typical Use |
|---|---|---|---|---|
