Zoben inji (mai maida hankali) ma'auratan maganadisu zuwa na'urori masu auna firikwensin da ke saman saman allo. Na'urorin firikwensin firikwensin guda biyu (1 da 2) na iya gano kwararar halin yanzu guda biyu. Ana aika siginar da aka gano na yanzu zuwa allon EXTB sannan zuwa tsarin sarrafawa. LEDs ja guda biyu suna nuna matsayin kowane da'irar ji na yanzu, suna haskakawa lokacin da aka gano halin yanzu.

5. Kanfigareshan Daidaita-Board Multi-Board

Don manyan aikace-aikace na yanzu, ana buƙatar SCRs de-excitation da yawa. Kowane SCR ana sarrafa shi ta hanyar EDEX guda ɗaya wanda aka saita a cikin tsarin Jagora-Mabiyi. An haɗa wutar lantarki ta J1, J2 da na gama gari zuwa allon Mabiya ta igiyoyin EPL; Mabiya ba su da haɗin kai zuwa J1 da J2. Jumpers JP1 da JP2 suna saita allon EDEX azaman Jagora ko Mabiyi.
