Isiguquli seCable Usb Ukuya kwiRs232 Rs485 Ukuya kwi-Ethernet Rs232 Ukuguqulela Usb KwiRs232

Ⅰ.Amagqabantshintshi
Ngophuhliso oluqhubekayo lweshishini lePC, ujongano olukhulu lweeperipheral (ezifana neDB9 serial port interfaces) yeePC zakudala ziyacinywa ngokuthe ngcembe, kodwa izixhobo ezininzi ezibalulekileyo kwindawo yeshishini kufuneka zisebenzise ujongano lweRS485 ukufezekisa unxibelelwano lwedatha, zininzi kakhulu. abasebenzisi kufuneka Sebenzisa i-USB ukuzeRS232/ 422/485 isiguquli ukuqonda ukuhanjiswa kwedatha phakathi kwePC kunye nezixhobo zeRS232/422/485.

Le USB2.0 yendalo yonke ukuya kwi-RS232/422/485 isiguquli ayifuni unikezelo lwamandla lwangaphandle, iyahambelana ne-USB2.0, imigangatho ye-RS232/422/485, kwaye inokuguqula imiqondiso ye-USB enesiphelo esinye kwimiqondiso ye-RS232/422/485, ukubonelela Amandla okhuseleko lokunyuka kwe-600W, kunye nombane wokunyuka owenziwe emgceni ngenxa yezizathu ezahlukeneyo kunye ne-inter-electrode capacitance encinci kakhulu iqinisekisa ukuhanjiswa kwe-speed-speed ye-RS232/422/485 interface, kunye ne-RS232/422 /485 izibuko iqhagamshelwe nge-DB9 yesidibanisi esiyindoda.Umguquli unokulibaziseka kwe-zero ukuhanjiswa ngokuzenzekelayo kunye nokuguqulwa kokufumana ngaphakathi kwi-converter, kwaye isiphaluka esisodwa se-I / 0 silawula ngokuzenzekelayo indlela yokuhamba kwedatha.

I-USB kwi-RS232/422/485 converter inokubonelela ngoqhagamshelwano oluthembekileyo kwi-point-to-point kunye ne-point-to-multipoint yonxibelelwano, i-RS485 i-point-to-multipoint umguquleli ngamnye unokudibanisa ukuya kwii-256 ze-RS485 izixhobo, kunye ne-RS422/485 izinga lonxibelelwano. yi-300bps Ukuya kwi-3Mbps, i-RS232 izinga lonxibelelwano 300bps ukuya kwi-115200bps.Iimveliso zisetyenziswa kakhulu kwiinkqubo zolawulo oluzenzekelayo kwimizi-mveliso, iinkqubo zolawulo lofikelelo, iinkqubo zokuzimasa, iinkqubo zokuswayipha amakhadi, iinkqubo zokwakha ezizisebenzelayo, iinkqubo zamandla, kunye neenkqubo zokufunyanwa kwedatha.
