The device combines multiple functions: serial server, Modbus gateway, MQTT gateway, RS232 \u0026amp; RS485 to JSON, etc. The secondary Ethernet port can be used as a network switch or for cascading, and PoE* function is optional for both Ethernet ports. Provides two power supply ways: DC port (outer diameter: 5.5mm, inner diameter: 2.1mm) and screw terminal. The rail-mount casing is compact in size, easy to install, and cost-effective. Suitable for applications such as data acquisition, IoT gateway, security \u0026amp; IoT, and intelligent instrument monitoring.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003e* This product is a PoE power receiving device (PD), it needs to be connected to a PoE power supply and obtain power from the PSE device to work normally.\u003c\/em\u003e\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"feature-block feature-block-light\"\u003e\n\n\u003ch3\u003eVersion Options\u003c\/h3\u003e\n\n\u003cdiv class=\"version-grid\"\u003e\n\n\u003cdiv class=\"version-item\"\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0868\/0462\/7772\/files\/RS232-RS485-TO-ETH-B-details-5-1_ad69d576-6b34-4561-82df-747d11f033f5.jpg?v=1789032337\" alt=\"RS232 RS485 TO ETH (B)\"\u003e\n\u003cp\u003e\u003cstrong\u003eRS232 RS485 TO ETH (B)\u003c\/strong\u003e\u003cbr\u003eDual Serial Ports + Normal Network Port + Electrical Isolation\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"version-item\"\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0868\/0462\/7772\/files\/RS232-RS485-TO-ETH-B-details-5-2_b84f1e44-b22b-462d-8c4d-f9eb0df74379.jpg?v=1789032340\" alt=\"RS232 RS485 TO POE ETH (B)\"\u003e\n\u003cp\u003e\u003cstrong\u003eRS232 RS485 TO POE ETH (B)\u003c\/strong\u003e\u003cbr\u003eDual Serial Ports + PoE Network Port + Electrical Isolation\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\n\u003ctable\u003e\n\n\u003cthead\u003e\n\n\u003ctr\u003e\n\n\u003cth\u003e\u003c\/th\u003e\n\n\u003cth\u003eRS232 RS485 TO ETH (B)\u003c\/th\u003e\n\n\u003cth\u003eRS232 RS485 TO POE ETH (B)\u003c\/th\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/thead\u003e\n\n\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd colspan=\"3\"\u003e\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eDual serial ports\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003eNormal network port + Electrical isolation\u003c\/td\u003e\n\n\u003ctd\u003ePoE network port + Electrical isolation\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eProduct Type\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd colspan=\"2\"\u003eSerial server, Modbus gateway, MQTT gateway\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eBasic function\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd colspan=\"2\"\u003eBidirectional transparent data transmission between RS232 \u0026amp;
