2019 Umgangatho ophakamileyo we-Rs232 Ukuya kwi-Rs485-E1-4FE ujongano loMguquli JHA-CE1fF4p (uLsolation ngokomzimba) - 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 kunye. Olu jongano lwe-multiplexer lunokusombulula le ngxaki.
