2019 High quality Rs232 to Rs485 - E1-4 Channel RS232/RS422/RS485 Converter JHA-CE1D4/R4/Q4 – JHA

E1-4 Channel RS232/RS422/RS485 ConverterJHA-CE1D4/R4/Q4

Txheej txheem cej luam

Qhov no interface converter yog raws li FPGA, muab 4Channel RS232/485/422 kis tau tus mob ntawm E1 interface. Cov khoom tawg los ntawm kev tsis sib haum xeeb ntawm cov tsoos serial interface kev sib txuas lus deb thiab kev sib txuas lus tus nqi, dhau li ntawd, nws kuj tuaj yeem daws cov teeb meem electromagnetic cuam tshuam, hauv av nplhaib cuam tshuam thiab xob laim puas. Cov cuab yeej zoo heev txhim kho kev ntseeg siab, kev ruaj ntseg thiab tsis pub lwm tus paub ntawm cov ntaub ntawv sib txuas lus. Nws yog dav siv rau ntau yam kev lag luam kev lag luam, kev tswj cov txheej txheem thiab kev tswj xyuas kev khiav tsheb, tshwj xeeb tshaj yog rau lub txhab nyiaj, thiab Fais fab thiab lwm cov haujlwm thiab cov tshuab uas muaj cov kev cai tshwj xeeb ntawm kev cuam tshuam electromagnetic ib puag ncig. RS232 / RS485 / RS422 channel tuaj yeem xa cov ntaub ntawv hloov pauv tau asynchronously 0Kbps-57600Kbps baud tus nqi.
