The LDM70 provides complete isolation with optical couplers and a DC-DC converter, supports RS-232 data rates from 0 to 57,600 baud, and is optimized for video display terminals and other RS-232 devices in harsh environments. Distances vary with baud rate: up to 3 miles (about 5 km) at 9,600 baud, roughly 1 mile (1.7 km) at 19,200 baud, and about 0.5 miles (0.8 km) at 57,600 baud. It uses two DC-continuity twisted-pair conductors and supports four-wire full duplex or two-wire simplex operation, with Data Terminal Ready and Carrier Detect handshake available without extra wires. The unit includes surge protection and four LED diagnostic indicators, and it comes in a rugged aluminum enclosure compact enough to mount on the back panel of VDT units, saving space while keeping the serial link isolated in industrial environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Burr-Brown","offers":[{"title":"New","offer_id":51677472194862,"sku":null,"price":72.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d7c42e69-7d58-449a-aa63-ced7857d0b7f.jpg?v=1769563436","url":"https:\/\/plgautomation.com\/products\/burr-brown-ldm70-industrial-limited-distance-modem","provider":"PLG Automation ","version":"1.0","type":"link"}
