RS-485 inzira yekutaurirana ine mapoinzi akawanda, iyo inoshandisa mawaya maviri akasonwa (two-core wires) pakutumira data. Matanho akadzama ekubatanidza mudziyo we serial kune RS-485 interface yeMoxamudziyo ndewekuti:
Danho 1: Simbisa Device Interface uye Pin Definitions
Tsanangudzo dzePin dzingasiyana pakati pemhando dzakasiyana dzezvishandiso. Zvinokurudzirwa kubata mugadziri anoenderana kuti usimbise tsananguro dzePin dzakarurama usati waisa waya!
MOXAzvigadzirwa zvinonyanya kuva nemhando nhatu dzinotevera dzemaports eserial:
Nzira yekubatanidza waya yeDB 9 interface uye mamodheru anoshanda ndeaya anotevera:
Nzira yekubatanidza waya yeRJ 45 interface uye mamodheru anoshanda ndeaya anotevera
Kutevedzana kwewiring ye terminal interface uye mamodheru anoshanda ndeaya anotevera:
Danho rechipiri: Batanidza Uchishandisa Matambo
Muenzaniso 1: Kubatanidza mudziyo weMoxa kune mudziyo mumwe chete weRS-485. Pakubatanidza mudziyo weMoxa nemudziyo weserial, batanidza mapini akanaka (B) kumapini akanaka (B) uye mapini asina kunaka (A) kumapini asina kunaka (A).
Muenzaniso wechipiri: Pakubatanidza mudziyo weMOXA kumidziyo yakawanda yeRS-485, panofanira kushandiswa kubatanidza chain-chain. Materminal ese eA(+) emidziyo akabatana akaenzana nemutsetse webhazi wakanaka, uye materminal ese eB(-) emidziyo akabatana akaenzana nemutsetse webhazi usina kunaka.
Muenzaniso wechitatu: Zvirambidzo zvekupera simba zvinofanirwa kuwedzerwa. Kana NPort iine chirambidzo chekupedzisira chakavakirwa mukati (semuenzaniso, chirambidzo chekupedzisira chakavakirwa mukati cheNPort 5450 chinogona kuvhurwa kuburikidza neswitch yeDIP (kazhinji SW 3 ndiyo switch yekupera simba), saka chirambidzo chekupedzisira chete ndicho chinofanira kuwedzerwa pamagumo elink, sezvakaratidzwa mudhayagiramu iri pazasi.
Muenzaniso wechina: Kana NPort isina chinodzivisa magumo chakavakirwa mukati, chinogona kuwedzerwa kumativi ese eRS-485 link, newaya inoratidzwa mudhayagiramu iri pazasi.
