Iyada oo horumarka joogtada ah ee warshadaha PC-ga, is-dhexgalyo waaweyn oo waaweyn oo kala duwan (sida DB9 isku-xidhka dekedaha serial) ee kombuyuutarrada hore ee casriga ah ayaa si tartiib tartiib ah loo kansalay, laakiin aalado badan oo muhiim ah oo ku yaal deegaannada warshadaha waxay u baahan yihiin inay adeegsadaan is-dhexgalka RS485 si loo gaaro isgaarsiinta xogta, aad u badan. Isticmaalayaasha waxay u baahan yihiin Isticmaalka USBRS232/ 422/485 beddele si loo xaqiijiyo gudbinta xogta u dhaxaysa PC iyo RS232/422/485 aaladaha.

Qalabkan caalamiga ah ee USB2.0 ilaa RS232/422/485 uma baahna sahay koronto dibadeed, wuxuu la jaan qaadayaa heerka USB2.0, RS232/422/485, wuxuuna u rogi karaa calaamadaha USB-ga hal dhamaadka ah ee calaamadaha RS232/422/485, bixinta Awoodda ilaalinta qulqulka ee 600W, iyo sidoo kale korantada kor u kaca ee ka soo baxda khadka sababo kala duwan awgood iyo awoodda aadka u yar ee inter-electrode capacitance waxay hubisaa gudbinta xawaaraha sare ee RS232/422/485 interface, iyo RS232/422 / 485 dekeddu waxay ku xidhan tahay isku xidhaha lab ee DB9.Beddeliyuhu waxa uu leeyahay dib udhigis eber ah oo toos ah iyo beddelka soo dhawaynta gudaha beddelka, iyo wareegga I/0 ee gaarka ah ayaa si toos ah u koontaroolaya jihada socodka xogta.

Qalabka USB-ga ee RS232/422/485 wuxuu ku siin karaa xiriir la isku halayn karo oo loogu talagalay isgaarsiin-dhibic-ilaa-multipoint, RS485 dhibic-ilaa-multipoint beddele kasta wuxuu isku xiri karaa ilaa 256 RS485 aaladaha, iyo heerka isgaarsiinta RS422/485 waa 300bps Ilaa 3Mbps, RS232 heerka isgaarsiinta 300bps ilaa 115200bps.Alaabooyinka waxaa si weyn loogu isticmaalaa nidaamyada xakamaynta automation-ka warshadaha, nidaamyada kontoroolka gelitaanka, nidaamka xaadirinta, nidaamyada kaadhka jiidhista, nidaamka automation-ka ee dhisma, nidaamyada korantada, iyo nidaamyada xogta.
