The Serial Gateway range covers mini DTUs, CAN-to-serial gateways, standard multi-serial-port DTUs, and cellular industrial gateways/routers for field serial networking.

Model Groups and Suffixes ​

The groups and communication suffixes below summarize the serial gateways. Check each model's specification for its exact serial-port configuration and interfaces; the model group alone does not describe every option.

  • Y201 / Y211: mini DTU series
  • Y201C: single-CAN-to-serial gateway
  • Y202 / Y204 / Y208: standard multi-port DTU series
  • Y212: cellular gateway/router series

Common suffix meanings:

  • G = 4G cellular
  • W = Wi-Fi
  • R = RJ45 Ethernet
  • L = LoRa
  • GWR = 4G + Wi-Fi + RJ45 multi-link
  • C = CAN-to-serial gateway

The communication suffix identifies the model variant; it is not a complete list of interfaces. Y202-W is the Wi-Fi-only variant, while Y202-R is the RJ45 Ethernet variant.

ExampleModel interpretation
Y201-GMini DTU with a 4G Cat.1 uplink.
Y201-LMini DTU for LoRa data transmission.
Y202-WDual-port DTU with Wi-Fi only.
Y204-RFour-port serial DTU with RJ45 Ethernet.
Y208-REight-port serial DTU with RJ45 Ethernet.

Some model specifications list additional ordering suffixes for serial configurations. For example, Y202-R-6H selects one RS232 and one RS485 port. Use those model-specific SKU tables; do not add a configuration suffix to models whose specification lists interface options separately.

Quick Selection Guide ​

  1. For compact and low-power deployments, choose Y201/Y211 mini DTUs.
  2. For CAN-to-serial conversion, choose Y201C.
  3. For centralized networking of multiple serial ports, choose Y202/Y204/Y208 standard DTUs.
  4. For cellular serial networking, choose Y212-G; for 4G, Wi-Fi, and Ethernet link switching, choose Y212-GWR. Confirm deployment-country and operator band compatibility with the Country Coverage Quick Guide.
