INKONZO
Ngemva kokuxhuma amasignali angaphandle nokushintsha ukunikezwa, imojula ye-SM3 isilungele ukusebenza. I-diode eluhlaza ekhanyisiwe ikhombisa ukusebenza kwemojuli. I-diode eluhlaza (RxD) ikhombisa ukuvota kwemojuli, nokho i-diode ephuzi (TxD), impendulo yemojuli. Ama-Diode kufanele akhanyise ngomjikelezo ngesikhathi sokudluliswa kwedatha, kokubili ngesixhumi esibonakalayo se-RS-232 ne-RS-485. Isiginali "+" (itheminali 3) ingu-5 V ephumayo enomthwalo owamukelekayo ongu-50 mA. Umuntu angayisebenzisela ukuhlinzeka ngamasekethe angaphandle.
Wonke amapharamitha wemojula angahlelwa kusetshenziswa i-RS-232 noma RS-485. Ichweba le-RS-232 linemingcele yokudlulisela njalo ngokuhambisana nedatha yezobuchwepheshe, yini eyenza uxhumano nemodyuli, ngisho nalapho imingcele ehleliwe yokukhishwa kwedijithali ye-RS-485 ingaziwa (ikheli, imodi, isilinganiso).
Izinga le-RS-485 livumela ukuxhumana okuqondile kumadivayisi angu-32 kusixhumanisi esisodwa se-serial esingu-1200 m ubude. Ukuxhuma inombolo ephezulu yamadivayisi kuyadingeka ukuthi usebenzise izisetshenziswa ezengeziwe ezihlukanisa umlamuli (isb. PD51 converter/repeater). Indlela yokuxhuma isixhumi esibonakalayo inikezwe kumanuwali yomsebenzisi wemojula (umdwebo 5). Ukuze uthole ukudluliselwa okulungile kuyadingeka ukuxhuma imigqa A no-B ngokuhambisana nokulingana kwabo kwamanye amadivaysi. Ukuxhuma kufanele kwenziwe ngocingo oluvikelekile. Isihlangu kufanele sixhunywe endaweni yokuvikela endaweni eyodwa. Ulayini we-GND usebenza ekuvikeleni okwengeziwe komugqa wesixhumi esibonakalayo ekuxhumekeni okude. Umuntu kufanele ayixhume esikhumulweni sokuzivikela (lokho akudingekile ukuze kusetshenziswe isikhombimsebenzisi esifanele).
Ukuthola uxhumano nekhompyutha ye-PC ngembobo ye-RS-485, isiguquli esibonakalayo se-RS-232/RS-485 sibalulekile (isb. isiguquli se-PD51) noma ikhadi le-RS-485.

NGAPHAMBI KOKUTHI KUZOMENYEZELWA UMONAKALO
| IZIMPAWU | INQUBO | AMANOTHI |
| 1. I-module diode eluhlaza ayikhanyi. | Hlola ukuxhumeka kwentambo yenethiwekhi. | |
| 2. Imojula ayikusunguli ukuxhumana nesisetshenziswa esiyinhloko ngembobo ye-RS-232. | Hlola ukuthi ikhebula lixhunywe kusokhethi elifanele kumojuli. Hlola ukuthi idivayisi eyinhloko isethwe yini ku-baud rate 9600, imodi 8N1, ikheli 1. |
(RS-232 inezinhlaka zokudlulisela njalo) |
| Ukushoda kokusayiniswa kokudluliswa kokuxhumana ku-RxD kanye | ||
| TxD diodes. | ||
| 3. Imojula ayikusunguli ukuxhumana nesisetshenziswa esiyinhloko ngembobo ye-RS-485. Ukushoda kokusayiniswa kokudluliswa kokuxhumana kuma-diode e-RxD ne-TxD. |
Hlola ukuthi ikhebula lixhunywe kusokhethi elifanele kumojuli. Hlola ukuthi idivayisi eyinhloko isethwe kumingcele efanayo yokudlulisela njengemojula (izinga le-baud, imodi, ikheli) Uma kunesidingo sokushintsha amapharamitha wokudlulisela lapho umuntu engakwazi ukusungula ukuxhumana nge-RS-485, umuntu kufanele asebenzise ichweba i-RS-232 elinemingcele yokudlulisela engashintshi (uma kwenzeka kuba nezinkinga ezengeziwe bheka iphuzu 2). Ngemva kokushintsha amapharamitha e-RS-485 ukuze adingeke, umuntu angashintshela embobeni ye-RS-885. |
