Fa'amatalaga

RS-485 o se fa'atonuga na'o le eletise. E le pei o tulaga faʻataʻitaʻiga atoa, lea e faʻamatalaina ai galuega, masini, ma eletise, RS-485 naʻo le faʻamalamalamaina o uiga eletise o faʻatonuga ma tagata e taliaina e mafai ona faʻaaogaina e faʻatino ai se laina paleni multidrop. O lenei tulaga, e ui i lea, o loʻo faʻamoemoe e faʻasino i tulaga maualuga maualuga, e pei ole DL/T645, mo se faʻataʻitaʻiga, lea e faʻamatalaina ai le fesoʻotaʻiga.

mo mita eletise eletise i Saina, faʻamaonia le RS-485 o le tulaga faʻavae faʻaletino.

Vaega

1. Tete'e vevela, mumu mumu

2.excellent insulation fa'atinoga, fa'atinoga fa'atupu kemisi mautu

3. lelei tele fa'atinoga fa'asalalauga ona o le fa'aogaina o le polyethylene maualuga mo le fa'aluina uaea talipupuni

4.Effective teteʻe i le electromagnetic faʻalavelave ona o le faʻaaogaina o se ituaiga fou o le alumini pepa, faʻapipiʻi faʻamau apamemea faʻapipiʻi lua-laupapa talipupuni.

Talosaga

O fa'ailoga RS-485 o lo'o fa'aogaina i le tele o ituaiga komepiuta ma faiga fa'aautomatika. I totonu o se komepiuta, e mafai e le SCSI-2 ma le SCSI-3 ona faʻaogaina lenei faʻamatalaga e faʻatino ai le faʻaogaina o le tino mo le tuʻuina atu o faʻamatalaga i le va o le pule ma le tisiki. RS-485 o lo'o fa'aogaina mo feso'ota'iga fa'amatalaga maualalo i va'alele fa'atau pasi. E mana'omia le la'ititi o uaea ma e mafai ona fa'asoa uaea i le va o nofoa e tele, fa'aitiitia ai le mamafa.
