Around 1,200 serial commands can be stored in the gateway.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBidirectional KNX to RS485 gateway\u003c\/li\u003e\n\u003cli\u003eApprox. 1,200 serial commands storable\u003c\/li\u003e\n\u003cli\u003eRS485 only: galvanically isolated, 3 screw terminals, 120 Ω termination by jumper\u003c\/li\u003e\n\u003cli\u003eUSB port; configured with the KNX-SERIAL-GW-II PC tool\u003c\/li\u003e\n\u003cli\u003eKNX galvanically separated from the serial side\u003c\/li\u003e\n\u003cli\u003eAuxiliary supply 9-30 VDC, 100 mA (isolated, polarity-safe) or USB\u003c\/li\u003e\n\u003cli\u003e2-module DIN rail, IP20, -5 to +45 °C (23 to 113 °F)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eArticle no.\u003c\/th\u003e\n\u003ctd\u003e40210182\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eKNX bus voltage\u003c\/th\u003e\n\u003ctd\u003eKNX 20-32 VDC (approx. 150 mW)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower consumption\u003c\/th\u003e\n\u003ctd\u003eapprox. 150 mW from KNX; aux 9-30 VDC up to 100 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAuxiliary supply\u003c\/th\u003e\n\u003ctd\u003e9-30 VDC, 100 mA, internally galvanically isolated, polarity-safe – or USB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInputs \/ outputs \u0026amp; connections\u003c\/th\u003e\n\u003ctd\u003eKNX terminal; RS485 only (250 kBaud, galvanically isolated, 3 x screw terminals 0.8 mm2 (approx. 18 AWG), 120 Ohm termination by jumper); USB Type B per datasheet; 3 x 16-step rotary switch, T1, PRG + LED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProtection rating\u003c\/th\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMounting\u003c\/th\u003e\n\u003ctd\u003eDIN rail, 2 TE (modules)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating temperature\u003c\/th\u003e\n\u003ctd\u003e-5 to +45 °C (23 to 113 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.arcus-eds.de\/fileadmin\/download.arcus-eds.de\/4000_Gateways\/4300_RS232_RS485\/4320_e1_KNX-GW2-RS485-2TE.pdf\" target=\"_blank\" rel=\"noopener\"\u003eProduct datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.arcus-eds.de\/fileadmin\/download.arcus-eds.de\/4000_Gateways\/4200_GW_DMX\/KNX-SERIAL-GW-II-setup.zip\" target=\"_blank\" rel=\"noopener\"\u003eETS application\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003e(CE certified; not UL\/NRTL listed — verify local code requirements before specifying in US installations)\u003c\/em\u003e\u003c\/p\u003e","brand":"ARCUS EDS","offers":[{"title":"Default Title","offer_id":50554319143168,"sku":"40210182","price":524.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/4161\/5360\/files\/4320_KNX-GW-RS485-2TE_40210182.png?v=1791427814","url":"https:\/\/www.knxsupply.com\/products\/arcus-knx-gw2-rs485-2te","provider":"KNX Supply","version":"1.0","type":"link"}
