It converts the TD and RD RS-232 lines to balanced half-duplex RS-485 signals.   The unit is powered from the RS-232 data and handshake lines whether the lines are high or low. An external power supply can be connected to two terminals on the RS-485 connector if no handshake lines are available. The 485SD9TB has a DB-9 female connector on the RS-232 side and a terminal block connector on the RS-485 side.\u003cbr\u003eBrand name(s) : B\u0026amp;B Electronics\u003ci\u003e\u003cbr\u003e\u003c\/i\u003e\u003cbr\u003e\u003ci\u003eNot backwards compatible \u003c\/i\u003ewith RS422 (\u003cb\u003e4 wire\u003c\/b\u003e).\u003cbr\u003e For an RS422 \/ 485 compatible converter (with DIP switch) \u003cb\u003esee \u003ca href=\"http:\/\/www.be-electronics.com\/product_p\/4wsd9tb.htm\" target=\"_blank\"\u003e\u003cinline style=\"color: rgb(149, 55, 52);\"\u003e4WSD9TB\u003c\/inline\u003e\u003c\/a\u003e\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003eAlso known as  \"485\", \"RS485\", \u0026amp; \"RS-485\"   \u003cbr\u003eFor a compatible \"\u003cb\u003elow capacitance\"\u003c\/b\u003e cable , see \u003cb\u003e\u003ca href=\"http:\/\/www.be-electronics.com\/product_p\/9842.htm\" target=\"_blank\"\u003e9842\u003c\/a\u003e\u003c\/b\u003e","brand":"B\u0026E Electronics Ltd","offers":[{"title":"Default Title","offer_id":47099828666604,"sku":"485SD9TB","price":133.61,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/0092\/6444\/files\/485SD9TB-2.jpg?v=1775750212","url":"https:\/\/be-electronics.com\/products\/b-b-485sd9tb-rs232-to-rs485-converter-db9f-terminal-block-not-backwards-compatible-with-rs422","provider":"store@be-electronics.com","version":"1.0","type":"link"}
