Musanagwiritse ntchito chida cha obd-II chosinthira kuti mudziwe momwe galimotoyo iperekedwe mgalimotoyi, ziyenera kutsimikiziridwa kuti injini yagalimoto siiyambitsidwa. Kenako ikani pulagi ya chida chosinthira mu mawonekedwe a OBD-II yomwe ili m'munsi mwa Cab yagalimoto, ndikuyambitsa chida chogwirizira.

Izi zochuluka, kuphatikizapo kutentha, kukakamizidwa ndi kuwuma, nthawi zambiri kumakomedwa ndi ma exares ofananira, ndikutumiza ku doko la Analog kwa wolamulira. Mwa njira yoyenera komanso yokwanira, mawonekedwe ophatikizika a analog amatha kunyamula molondola ndikusintha kusintha kwa chizindikiro, motero kulondola.
Pogwiritsa ntchito piritsi lokhala ndi magalimoto, mawonekedwe ophatikizika a analog amatha kugwiritsidwa ntchito kulandira ma andalog zizindikiro pamagalimoto agalimoto (monga sensor sensor, ensor, etc.), kotero kuti adziwe zolakwika zagalimoto.

Ili ndi zikhomo zisanu ndi zitatu, zomwe zilipo 1 ndi 2 zimagwiritsidwa ntchito potumiza zizindikiro zosiyanasiyana, ndipo 3 ndipo 6 amagwiritsidwa ntchito polandila signals mosiyanasiyana, kuti zitheke kusokoneza njira zogwiritsira ntchito chizindikiro. Zikhomo 4, 5, 7 ndi 8 zimagwiritsidwa ntchito kwambiri ndikukhazikitsa ndikutchingira, kuonetsetsa kukhazikika kwa kufalikira.
Kudzera mu mawonekedwe a RJ45, piritsi lam'magalimoto limatha kufalitsa deta ndi zida zina za network (monga rought, zopsa, etc.) Kuthamanga kwambiri.

Makina a RS485 ndi mawonekedwe olumikizirana a theka, omwe amagwiritsidwa ntchito popanga mafakitale a mafakitale ndi kulumikizana kwa data. Imatengera njira yosinthitsira chizindikiro, kutumiza ndi kulandira deta kudzera pa zikwangwani za siginesi (A ndi B). Ili ndi luso la kugwiritsira ntchito magwiritsidwe ntchito ndipo imatha kukana kusasamala kwa entimagneti, kusayanjanitsa ndi zigawo zaphokoso. Kutalikirana kwa Rs485 kumatha kufikira 1200m popanda kubwereza, zomwe zimapangitsa kuti zikhale zosangalatsa pakugwiritsa ntchito nthawi yayitali. Chiwerengero chokwanira cha zida zomwe RS485 Basi akhoza kulumikizidwa ndi 32. Thandizani zida zingapo kuti mulumikizane pa basi yomweyo, yomwe ndi yabwino kwambiri yoyang'anira ndi kuwongolera. RS485 imathandizira kufalitsa deta yapamwamba kwambiri, ndipo kuchuluka kwake kumatha mpaka 10Mveps.

Makina a RS232 ndi gawo lofanana la kulumikizana pakati pazida, makamaka kuti mulumikizane ndi zida za deta (Dte) ndi zida zolankhulira za data (DCE) kuzindikira ndi kuphweka kwake. Komabe, mtunda wopititsira maximun ndi pafupifupi 15 metres, ndipo kuchuluka kwake kufalitsa kuli kochepa. Mulingo wapamwamba kwambiri nthawi zambiri umakhala 20kbps.
Nthawi zambiri, RS485, RS422 ndi RS232 ndi mfundo zonse zolumikizirana, koma mawonekedwe awo ndi zochitika zawo zimakhala zosiyana. Mwachidule, mawonekedwe a RS232 ndioyenera kugwiritsa ntchito zomwe sizikufuna kufalitsa kwa nthawi yayitali, ndipo ili ndi mgwirizano wabwino ndi zida zakale ndi zina. Pakufunika kufalitsa deta munjira zonse nthawi yomweyo ndipo kuchuluka kwa zida zolumikizidwa ndi zosakwana 10, RS42 ikhoza kukhala chisankho chabwino. Ngati zida zopitilira 10 zikufunika kulumikizidwa kapena kuchuluka kwa kufalitsa mwachangu, RS45 ikhoza kukhala yabwino.
