Up to 921,600 data transfer rates and the 128 byte deep transmit and 256 byte receive FIFOS, coupled with 1Mbit line drivers deliver uncompromising performance on your laptop\/PC.\u003cbr\u003e\u003cbr\u003eUSB to serial is the quick low cost way to connect your computer to a serial comms enabled device. Boost software gives industry leading functionality and compatibility.\u003cbr\u003e\u003cbr\u003eRS422 Standard: RS422 allows one transmitter and up to 10 receivers with data transmitter rates up to 10 megabits per second for distances up to 40 feet and up to 100 Kilobits per second for distances up to 4000 feet (1219 metres).To achieve good long distance noise immunity, 2 wires are used to carry each signal, configured as a twisted pair of cables. The TXD pair and RXD pair are used to carry the data whilst the RTS pair and CTS pair lines are used for handshaking. Thus 2 twisted pairs are used without handshaking and 4 twisted pair cable is used with handshaking both these schemes allow full duplex data communications.\u003cbr\u003e\u003cbr\u003eRS485 Standard: RS485, based on the RS422 standard allows up to 32 driver\/receivers pairs on a party line data bus. Whilst only one of these should be transmitting data at any time, the rest can all simultaneously listen to the data. Handshaking is performed by software protocol. Two twisted pairs form a full duplex system. Often only one twisted pair cable is used as the TXD and RXD lines are tied together; this is known as half duplex mode. Traditionally, the RTS signal is used as the party line control to tristate the PC’s transmitter, but in multitasking operating systems like Windows or Linux the only reliable method is hardware autogating. Brainboxes RS422\/485 products implement a state of the art autogating circuit thus ensuring error free communications in half duplex configuations.\u003cbr\u003e\u003cbr\u003eThese products do away with traditional issues with USB technology so you can buy with confidence!\u003cbr\u003e\u003cbr\u003eWith Brainboxes industry renowned Lifetime Warranty and Lifetime Support!*\u003cbr\u003e(online registration required).\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable class=\"generic\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003eTechnical details\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable length\u003c\/td\u003e\n\u003ctd\u003e9.84\" (0.25 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFull duplex\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003eNetwork\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData transfer rate\u003c\/td\u003e\n\u003ctd\u003e0.9 Mbit\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003ePerformance\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFull duplex\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct colour\u003c\/td\u003e\n\u003ctd\u003eBlue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003eCertificates\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertification\u003c\/td\u003e\n\u003ctd\u003eCE, ROHS, WEEE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003eColour\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct colour\u003c\/td\u003e\n\u003ctd\u003eBlue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003ePorts \u0026amp; interfaces\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUSB 2.0 ports quantity\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSerial ports quantity\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector(s)\u003c\/td\u003e\n\u003ctd\u003e1x RS422\/485\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHost interface\u003c\/td\u003e\n\u003ctd\u003eUSB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003eDesign\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct colour\u003c\/td\u003e\n\u003ctd\u003eBlue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertification\u003c\/td\u003e\n\u003ctd\u003eCE, ROHS, WEEE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003eFeatures\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFull duplex\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003eWeight \u0026amp; dimensions\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e3.54\" (90 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e1.38\" (35 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e0.787\" (20 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e4.41 oz (125 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003eOther features\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData transfer rate\u003c\/td\u003e\n\u003ctd\u003e0.9 Mbit\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable length\u003c\/td\u003e\n\u003ctd\u003e9.84\" (0.25 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnectivity technology\u003c\/td\u003e\n\u003ctd\u003eWired\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMac compatibility\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible operating systems\u003c\/td\u003e\n\u003ctd\u003eWin 7, Vista, XP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Brainboxes","offers":[{"title":"Default Title","offer_id":51543685628226,"sku":"US-324","price":78.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0969\/3659\/1682\/files\/HBWXwHVx3k6ebFqK7KrQBw.c-m_06580a4d-95a4-4f87-b190-923c6b9ba4ee.jpg?v=1768914660","url":"https:\/\/leverify.com\/products\/50963765","provider":"Leverify","version":"1.0","type":"link"}
