Overview

Y212-G connects RS232 and RS485 devices to a compatible 4G network for field data collection, transparent serial transport and remote configuration. Match the supplied radio version to the destination country, carrier and SIM settings.

Key features

  • LTE Cat.4 cellular uplink; network availability depends on carrier bands, SIM configuration and site coverage.
  • RS232 and RS485 interfaces; confirm the required serial hardware before ordering.
  • TCP, UDP, HTTP/HTTPS, MQTT/MQTTS, WebSocket and Modbus RTU/TCP gateway functions.
  • Local and remote configuration, OTA firmware updates, logs and alarm reporting.
  • 6–28 V DC supply and DIN-rail or panel mounting.

How it works & selection

Country and Carrier Compatibility

This model is not recommended for the United States or Canada. EU/UK and other markets may have only partial band overlap. Check the datasheet country table, local carrier bands, and coverage at the installation site before ordering. It is not a universal global-band gateway.
