Irack yensimbi engu-19” ejwayelekile ye-3U efakwe ngephaneli yonke inomklamo we-slideway plug-in esiteshini ngasinye; ukufakwa okujwayelekile kwekhabhinethi ye-3U kubonakala ngokufaka kalula, ivolumu encane (73% ye-AEC2392a) nokuphazanyiswa kwe-anti-EMI/RFI;
Ikhadi lokulawula eliyinhloko namakhadi amashaneli asethwe ngokuhlukana kodwa anomsebenzi wokubonisa okuhambisanayo. Ngesikrini esikhulu sokubonisa se-LCD sesiShayina, ikhadi lokulawula eliyinhloko lingakwazi ukubona ukusebenza kwemenyu yesiShayina kanye nokubonisa nokusebenza okusheshayo nokulula;
Amakhadi eziteshi angasebenza ngokuzimela ngaphansi kwemenyu ezimele. Ngakho, ukwehluleka kwekhadi lokulawula eliyinhloko noma ukwehluleka kwamanye amakhadi esiteshi ngeke kube nomthelela ekuqaphelweni kwegesi okujwayelekile kwamakhadi esiteshi;
Amakhadi eziteshi angathola isignali ye-4-20mA noma okokufaka kwesignali yenani lokushintsha futhi axhunywe kumadivayisi ahlukahlukene, okuhlanganisa izithoni zegesi ezivuthayo, izithoni zegesi ezinobuthi neziyingozi, izithonjana ze-oksijini, izithungatha zomlilo, izithonjana zentuthu/ukushisa nezinkinobho ezishaqisayo ezenziwa ngesandla, njll.;
