SKU: 40210182
✗ UL Listed
This product has not been certified by an NRTL (UL, ETL, CSA or equivalent). Installation in USA projects may require a Field Evaluation by a recognized laboratory. Consult your local AHJ before specifying.
~ Low Voltage · SELV
This device operates on a Safety Extra Low Voltage circuit — such as the KNX 29V bus or a DALI 16V bus (NEC Class 2). When powered by an NRTL-listed power supply, many AHJs accept non-listed SELV devices. Verify with your local AHJ before specifying.

The KNX-GW2-RS485-2TE translates KNX telegrams into RS485 serial commands and back, for integrating AV equipment, projectors and other serially controlled devices. Around 1,200 serial commands can be stored in the gateway.

This slim 2-module DIN-rail version has an RS485 port only (no RS232) plus USB. Data formats and commands are set with the arcus KNX-SERIAL-GW-II PC tool rather than ETS. A 9-30 VDC auxiliary supply or USB power is required.

Key Features

  • Bidirectional KNX to RS485 gateway
  • Approx. 1,200 serial commands storable
  • RS485 only: galvanically isolated, 3 screw terminals, 120 Ω termination by jumper
  • USB port; configured with the KNX-SERIAL-GW-II PC tool
  • KNX galvanically separated from the serial side
  • Auxiliary supply 9-30 VDC, 100 mA (isolated, polarity-safe) or USB
  • 2-module DIN rail, IP20, -5 to +45 °C (23 to 113 °F)
