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

Mwachidule

Chosinthira mawonekedwe ichi chimachokera ku FPGA, kupereka 4Channel RS232/485/422 kufalikira pa mawonekedwe a E1. Chogulitsacho chimadutsa zosemphana pakati pa mtunda wolumikizirana wamawonekedwe achikhalidwe komanso kuchuluka kwa kulumikizana, kuonjezera apo, zimathanso kuthetsa kusokoneza kwa ma elekitiroma, kusokoneza kwa mphete ndi kuwonongeka kwa mphezi. Chipangizocho chimathandizira kwambiri kudalirika, chitetezo komanso chinsinsi cha kulumikizana kwa data. Amagwiritsidwa ntchito kwambiri poyang'anira mafakitale osiyanasiyana, kuwongolera njira komanso nthawi zowongolera magalimoto, makamaka ku Banki, ndi Mphamvu ndi magawo ena ndi machitidwe omwe ali ndi zofunikira zapadera pakusokoneza ma electromagnetic chilengedwe. RS232/RS485/RS422 njira imatha kufalitsa deta yosinthika mosiyanasiyana 0Kbps-57600Kbps baud rate.
