Typical uses include controlling AV receivers, projectors or HVAC units, with around 1,200 commands stored in the device.\u003c\/p\u003e\u003cp\u003eThe gateway occupies 6 DIN-rail modules and is configured with the arcus KNX-SERIAL-GW-II PC software over USB Type B. It needs a 9-30 VDC auxiliary supply or USB power, and KNX is galvanically separated from the serial side.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBidirectional KNX to RS232 and RS485 gateway\u003c\/li\u003e\n\u003cli\u003eRS232 on D-Sub 9 male, up to 115.2 kBaud\u003c\/li\u003e\n\u003cli\u003eRS485 galvanically isolated, 3 screw terminals, 120 Ω termination by jumper\u003c\/li\u003e\n\u003cli\u003eApprox. 1,200 serial commands; data formats 8N1 to 8O2, 1\/1.5\/2 stop bits\u003c\/li\u003e\n\u003cli\u003eConfigured with the KNX-SERIAL-GW-II PC tool via USB Type B\u003c\/li\u003e\n\u003cli\u003eAuxiliary supply 9-30 VDC, 100 mA (isolated, polarity-safe) or USB\u003c\/li\u003e\n\u003cli\u003e6-module DIN rail, 107 x 75 x 31 mm (4.21 x 2.95 x 1.22 in), 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\u003e40210186\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 (250 kBaud, galvanically isolated, 3 x screw terminals 0.8 mm2 (approx. 18 AWG), 120 Ohm termination by jumper); RS232 D-Sub 9 male (pins 2\/3\/5, max 115.2 kBaud); USB Type B; 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\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e107 x 75 x 31 mm (4.21 x 2.95 x 1.22 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMounting\u003c\/th\u003e\n\u003ctd\u003eDIN rail, 6 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\/4310_e1_KNX-GW2-RS232-RS485.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":50554319175936,"sku":"40210186","price":537.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/4161\/5360\/files\/4310_KNX-GW2-RS232-RS485-6TE_40210186.png?v=1791427815","url":"https:\/\/www.knxsupply.com\/products\/arcus-knx-gw2-rs232-rs485","provider":"KNX Supply","version":"1.0","type":"link"}
