Umgangatho ogqwesileyo we-Rs485 Ukuya kwi-Rs232 Isiguquli sothotho-E1-4FE ujongano lokuguqulela JHA-CE1fF4p (uLsolation ngokwasemzimbeni) – JHA

I-E1-4FE ujongano lokuguqulelaJHA-CE1fF4p

      (Ukuzimela ngokwasemzimbeni）

Isishwankathelo

Esi siguquli sojongano lusekwe kwiFPGA. Ngaba uqaphele ukuhanjiswa kwedatha ye-4Channel Ethernet kwiisekethe ze-1E1,ukubonelela abasebenzisi nge-Ethernet yokufikelela kwinqanaba le-1984K. Isetyenziswa ngokubanzi kwizemali, izibambiso kunye namasebe okhuseleko ekufuneka abonelelwe ngamanethiwekhi amabini ahlukeneyo, kwaye zombini kwinethiwekhi ebonakalayo inokwahlulwa ngokupheleleyo. Umzekelo, uthungelwano lweshishini lwenkqubo yezemali, inethiwekhi ye-ofisi yangaphakathi kunye nenethiwekhi yoshishino ayinakudityaniswa. Olu jongano lwe-multiplexer lunokusombulula le ngxaki.
