It can automatically sense data direction and communication baud rate, not requiring any control or handshaking , and ensure transparent data . Equipment power supply and communication are completely isolated, with and static . It features long distance , high speed, stable and performance. Widely used for attendance machine, IC card charging system, automation control, access control system, parking lot, dining service system, highway toll system.\u0026lt;br \/\u0026gt; Common Ground:\u0026lt;br \/\u0026gt; 1. All devices on the same network segment must have a uniform ground to avoid common mode interference.\u0026lt;br \/\u0026gt; 2. When using centralized power supply, connect DC negative poles of all power (including the communication device power) of the same network segment together directly to form a common ground. At this time the ground is the DC power ground.\u0026lt;br \/\u0026gt; 3. When using individual power supply, connect the ground (black wire) pins of all the bus devices on the same network segment together to form a common ground.\u0026lt;br \/\u0026gt; \u0026lt;br \/\u0026gt; Specifications:\u0026amp;nbsp;\u0026lt;br \/\u0026gt; Recommended Value\u003cbr\u003e\u003cbr\u003e• Support Multi-machine Communication: Support multi-machine communication, up to 128 nodes can be connected, and the distance can reach 1200 meters.\u003cbr\u003e• Features: Data automatic control technology, automatically distinguish and control the data direction.\u003cbr\u003e• Multiple Measures: positive and negative 15KV ESD\u003cbr\u003e• 600W dual-channel TVS\u003cbr\u003e• 2.5KV communication isolation.\u003cbr\u003e\u003cbr\u003eColor: Green","brand":"Walfront","offers":[{"title":"Default Title","offer_id":52137206776090,"sku":"MCAB078NTWFRS","price":30.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/6772\/2266\/files\/61FlBCg6LAL.jpg?v=1777372196","url":"https:\/\/craftedyogi.com\/products\/industrial-grade-photoelectric-isolation-rs-485-repeater-dcdc-isolated-power-module-amplifier-converter","provider":"Craftedyogi","version":"1.0","type":"link"}
