Each serial port uses a DB-9M connector and can be software-configured as RS-232, RS-422, or RS-485, with RS-232 operating as DTE. A 10\/100 Mbps RJ-45 Ethernet interface provides TCP\/IP access to connected devices for remote data collection and control over a LAN or WAN. Management is available through the ESP Manager software, a Web Server, and Telnet, with configurable Console, Default, and Upgrade modes for setup and firmware maintenance. Firmware is version 3.0, and the ESP904 is powered by a 12 V DC supply via a power input. Typical applications include industrial automation, remote monitoring of multiple serial instruments, and SCADA-style data acquisition where multiple serial ports must be networked. \u003c\/p\u003e\u003c\/div\u003e","brand":"BB","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660474057006,"sku":null,"price":58.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_0962e8b8-a300-4662-8c9d-55df70ed3902.jpg?v=1769538014","url":"https:\/\/plgautomation.com\/products\/b-b-electronics-esp904-ethernet-to-serial-server","provider":"PLG Automation ","version":"1.0","type":"link"}
