Umgangatho ogqwesileyo we-Rs485 Ukuya kwi-Rs232 isiguquli sothotho-E1-RS485 Isiguquli seJHA-CE1D1 – JHA

E1-RS485 Convertsr JHA-CE1D1

Isishwankathelo

Lo mguquleli we-interface usekelwe kwi-FPGA, ukubonelela nge-E1 interface kunye ne-RS485 enye ye-serial interface, i-1Channel RS485 yokudluliselwa nge-E1 interface. Imveliso iqhekeza ukuchasana phakathi komgama wonxibelelwano lwe-serial yesiqhelo kunye nesantya sonxibelelwano, ngaphandle koko, inokusombulula ukuphazamiseka kwe-electromagnetic, ukuphazamiseka kweringi yomhlaba kunye nomonakalo wombane. Isixhobo siphucula kakhulu ukuthembeka, ukhuseleko kunye nemfihlo yonxibelelwano lwedatha. Isetyenziswa ngokubanzi kulawulo lwemizi-mveliso eyahlukeneyo, ulawulo lwenkqubo kunye nezihlandlo zolawulo lwezithuthi, ngakumbi kwiBhanki, kunye naMandla kunye namanye amacandelo kunye neenkqubo ezineemfuno ezizodwa zokuphazamiseka kombane wombane. Izinga lonxibelelwano lojongano lonxibelelwano lufikelela kwi-921.6KBPS.

Uhlobo oluncinci

Iimbonakalo

• Ngokusekwe kwi-self-copyright IC
• Iyakwazi ukubona ngokuzenzekelayo kwaye ilawule ukuhamba kwedatha ye-RS-485 ngaphandle kwemiqondiso yokuxhawula isandla ukulawula indlela yokuhamba kwedatha
• Yiba nesakhono sokubona ngokuzenzekelayo isantya se-baud yesiginali ye-serial port
• Ukuvavanya ngokuzenzekelayo isizathu se-matt yesixhobo kukuba ifowuni icinyiwe, okanye umgca we-E1 wophukile. Kwaye emva koko ubonise kwi-LED
• Ukubonelela nge-2 impedances: 75 Ohm unbalance kunye ne-120 Ohm ibhalansi;
• Inkxaso yoLawulo lweNethiwekhi yeSNMP
• Ijelo lothotho linokusasaza idatha yothotho eguquguqukayo ngokuhambelana 300 Kbps-921.6Kbps izinga le-baud
• Uthotho lwedatha yokuphindaphinda kwi-E1 inkxaso ye-ITU-T R.111 yokutsiba imo yekhowudi
• Uthotho lwezibuko ujongano lombane-ukhuseleko lufikeleleke kwi-IEC61000-4-5 (8/20μS) DM(Indlela eyamahluko): 6KV,Impedance (2 Ohm), CM(Indlela eqhelekileyo): 6KV, Imedance (2 Ohm) umgangatho
