The Y2 product family covers mini DTUs, standard multi-serial-port DTUs, and global industrial gateways/routers for field serial networking.
For deployment-country selection, see Country Coverage Quick Guide.
Model Naming
The diagram shows the Y2AB-X family format: A identifies the platform version, B is the port designation, and X identifies the communication type. For Y20x models, use the exact serial-port configuration in the model specification; the family code alone does not describe every interface option.
Y201 / Y211: mini DTU seriesY202 / Y204 / Y208: standard multi-port DTU seriesY212: global gateway/router series
Common suffix meanings:
G= 4G cellularW= Wi-FiR= RJ45 EthernetL= LoRaGWR= 4G + Wi-Fi + RJ45 multi-link
The communication suffix identifies the model variant; it is not a complete list of interfaces. For example, Y202-W also provides Ethernet.
| Example | Model interpretation |
|---|---|
Y201-G | Mini DTU with a 4G Cat.1 uplink. |
Y201-L | Mini DTU for LoRa data transmission. |
Y202-W | Dual-port DTU with Wi-Fi and Ethernet. |
Y204-R | Four-port serial DTU with RJ45 Ethernet. |
Y208-R | Eight-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.
