2019 Ubwino Wabwino Kwambiri Kutembenuza kwa Efaneti - E1-RS485 Converter JHA-CE1D1 - JHA

Zosintha za E1-RS485Chithunzi cha JHA-CE1D1

Mwachidule

Chosinthira mawonekedwe ichi chimachokera ku FPGA, kupereka mawonekedwe amodzi a E1 ndi mawonekedwe amodzi a RS485, kutumiza kwa 1Channel RS485 kudzera pa mawonekedwe a E1. Chogulitsacho chimadutsa zosemphana pakati pa mtunda wolumikizirana wamawonekedwe achikhalidwe komanso kuchuluka kwa kulumikizana, kuonjezera apo, zimathanso kuthetsa kusokoneza kwa ma elekitiroma, kusokoneza kwa mphete ndi kuwonongeka kwa mphezi. Chipangizocho chimathandizira kwambiri kudalirika, chitetezo komanso chinsinsi cha kulumikizana kwa data. Amagwiritsidwa ntchito kwambiri poyang'anira mafakitale osiyanasiyana, kuwongolera njira komanso nthawi zowongolera magalimoto, makamaka ku Banki, ndi Mphamvu ndi magawo ena ndi machitidwe omwe ali ndi zofunikira zapadera pakusokoneza ma electromagnetic chilengedwe. Kulumikizana kwa seriyo kumafika pa 921.6KBPS.

Chithunzi cha malonda

Mtundu wa Mini

Mawonekedwe

• Kutengera kudzikonda kwa IC
• Imatha kuzindikira ndi kuwongolera kuyenda kwa data ya RS-485 popanda ma siginecha ogwirana chanza kuti muwongolere kayendedwe ka data
• Khalani ndi kuthekera kodziwiratu kuchuluka kwa baud kwa siginecha ya doko
• Yesani zokha chifukwa cha matt ndikuti chipangizocho chazimitsidwa, kapena mzere wa E1 wathyoka. Kenako sonyezani pa LED
• Perekani 2 zolepheretsa: 75 Ohm kusalinganika ndi 120 Ohm balance;
• Thandizani SNMP Network Management
• Njira yotsatsira imatha kufalitsa deta yosinthika mosinthika 300 Kbps-921.6Kbps baud rate
• Siri data multiplexing mu E1 kuthandizira ITU-T R.111 kudumpha code code
• Kutetezedwa kwa doko lachitetezo cha mphezi-chitetezo chafika IEC61000-4-5 (8/20μS) DM(Mode Wosiyana): 6KV,Impedance (2 Ohm), CM(Common Mode): 6KV, Impedance (2 Ohm) muyezo
