E1-RS485 Liuar JHA-CE1D1

Va'aiga lautele

O lenei fa'aliliuga fa'afeso'ota'i e fa'avae i luga o le FPGA, tu'uina atu le tasi fa'aoga E1 ma le tasi RS485 feso'ota'iga fa'asologa, 1Channel RS485 fa'asalalauga e ala i le E1. O le oloa malepelepe e ala i feteʻenaʻiga i le va o fesoʻotaʻiga fesoʻotaʻiga fesoʻotaʻiga masani mamao ma le fua o fesoʻotaʻiga, e le gata i lea, e mafai foi ona foia faʻalavelave electromagnetic, faʻalavelave mama eleele ma faʻaleagaina uila. O le masini e matua faʻaleleia atili le faʻamaoni, saogalemu ma le le faalauaiteleina o fesoʻotaʻiga faʻamatalaga. E faʻaaogaina lautele mo le tele o pisinisi faʻatautaia, faʻagasologa faʻagasologa ma taimi faʻatonutonu feoaiga, aemaise lava mo Faletupe, ma Malosiaga ma isi vaega ma faiga o loʻo iai manaʻoga faʻapitoa ole siosiomaga faʻalavelave eletise. O feso'ota'iga feso'ota'iga fa'asologa e o'o atu ile 921.6KBPS.
