Y208-R is the high-density Ethernet DTU in the Yengear serial gateway range. It brings up to eight independent RS232 or RS485 channels onto IP networks while keeping each field bus separate. It is a better fit than stacking several small converters when a cabinet already has many meters, relays, controllers or serial instruments.
Best Fit
- Large control panels with many serial devices.
- Substation, metering, telemetry and factory data collection cabinets.
- Projects that need LAN1/LAN2 separation or redundant Ethernet wiring.
Key Features
- 8 independent serial channels, available as RS232, RS485 or mixed variants.
- Socket A and B on each port for concurrent SCADA, MES or cloud access.
- Dual 10/100Base-T RJ45 uplinks with independent MAC addressing.
- TCP, UDP, HTTP, MQTT and Modbus RTU to Modbus TCP conversion.
- Browser console, heartbeat, JSON upload, remote AT and HTTP OTA.

Ordering Notes
Choose the variant by serial interface mix: 8 RS232, 8 RS485, or 4 RS232 + 4 RS485. If the cabinet has both old RS232 instruments and RS485 buses, confirm the channel layout before ordering. Nobody enjoys rewiring a full cabinet twice.
