Ntchito yayikulu ya 485 converter ndikusintha chizindikiro cha RS-232 chokhazikika kukhala chosiyana RS-485 kapena RS-422 chizindikiro. Chifukwa cha kufalitsa uthenga wautali komanso mphamvu zotsutsana ndi kusokoneza, otembenuza a rs485 amagwiritsidwa ntchito kwambiri poyankhulana ndi chitetezo ndi zina. Komabe, ogwiritsa ntchito nthawi zambiri amakumana ndi kusokoneza kwa chizindikiro. Ndiye, nchiyani chomwe chimachititsa kuti chizindikiro cha rs485 chisokonezedwe?

1. Kufananiza kusokoneza, zomwe makamaka zimachokera ku zosayenera dongosolo katundu wofananira. Mwachitsanzo, mzere wa chizindikiro ndi wautali kwambiri, waya wambiri (kutalika) nyenyezi, katundu wambiri, palibe dongosolo lofanana ndi kukana, ndi zina zotero, zomwe zimapangitsa kuti dongosololi ligwire ntchito bwino ndikulephera kugwira ntchito mokhazikika.

2. Wamphamvu wamba mode kusokoneza. Izi nthawi zambiri zimayamba chifukwa cha kukhazikika kwachindunji kapena kosalunjika kwa zida zolandirira m'malo osiyanasiyana, zomwe zimapangitsa kulumikizana pakati pa mzere wazizindikiro ndi "malo opangira zida" kapena "chida cha digito" (nthawi zambiri 50 Hz) Chifukwa cha chizindikiro chochulukirapo. Kulandila kwa magwiridwe antchito nthawi zina kulibe, kapena ngakhale kusalandiridwa nthawi zonse. Kuphatikiza apo, kulandila kwa data sikungazindikirike ngati mtunda pakati pa kulandira ndi kutumiza ndi mita imodzi.

3. Kulephera kwa Hardware, nthawi zambiri chifukwa pali mbiri yamagetsi apamwamba pamzere (kugunda kwamphezi, kutayikira), kumayambitsa mavuto ndi rs485 converter chip ya zida zapayekha mu dongosolo, zomwe zimakhudza kulandila konse.

4. Zolakwika za mzere, monga dera laling'ono lapafupi kapena dera losweka mu mzere wa chizindikiro, nthawi zambiri zimapangitsa kuti dongosololi lizigwira ntchito kumaloko kapena limagwira ntchito bwino, koma ntchitoyo ndi yosakhazikika.
