It is bus-powered from the USB port and provides up to 2000 V RMS optical isolation between the USB host and the RS-422\/RS-485 side, helping protect equipment from surges and ground loops. The interface supports RS-422 and RS-485 operation with both 2-wire and 4-wire configurations and data rates up to 921.6 kbps. Features include removable terminal blocks for easy wiring, a high-retention USB connector, and mounting options for DIN rail or panel installation, with the option to ship with a USB cable. Within the USOPTL4 family, higher-port variants are available (BB-USOPTL4-2P and BB-USOPTL4-4P) for additional isolated channels, while the base 1-port USOPTL4DR model provides a single isolated RS-422\/RS-485 connection. TX\/RX activity indicators aid diagnostics, and the device is compatible with USB 1.0\/1.1\/2.0 hosts, fitting Advantech’s ULinx line of USB-to-serial converters. \u003c\/p\u003e\u003c\/div\u003e","brand":"Advantech","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657039872302,"sku":null,"price":362.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2031f4a6-bfe3-4bb1-822a-e038dffa0ce6.jpg?v=1769465455","url":"https:\/\/plgautomation.com\/products\/advantech-usoptl4-isolated-usb-to-rs-422-rs-485-converter","provider":"PLG Automation ","version":"1.0","type":"link"}
