2019 Mea hoʻololi Serial maikaʻi i Ethernet - E1-RS485 mea hoʻololi JHA-CE1D1 – JHA
2019 Mea hoʻololi Serial maikaʻi i Ethernet - E1-RS485 mea hoʻololi JHA-CE1D1 – JHA kikoʻī:
E1-RS485 Hulir JHA-CE1D1
Nānā nui
Hoʻokumu ʻia kēia mea hoʻololi hoʻololi ma FPGA, e hāʻawi ana i hoʻokahi kikowaena E1 a me hoʻokahi RS485 serial interface, 1Channel RS485 hoʻoili ma o E1 interface. Hoʻokaʻawale ka huahana ma o nā kūʻē ma waena o ka mamao o ke kamaʻilio serial interface a me ka helu kamaʻilio, ʻokoʻa, hiki iā ia ke hoʻonā i ka hoʻopili electromagnetic, ke komo ʻana o ke apo honua a me ka pōʻino uila. Hoʻomaikaʻi nui ka mea hana i ka hilinaʻi, palekana a me ka hūnā o ka kamaʻilio ʻikepili. Hoʻohana nui ʻia ia no nā ʻano ʻenehana like ʻole, ka mālama ʻana i ke kaʻina hana a me nā manawa hoʻokele kaʻa, ʻoi aku hoʻi no ka Bank, a me Power a me nā ʻāpana ʻē aʻe a me nā ʻōnaehana i loaʻa nā koi kūikawā o ke kaiapuni electromagnetic interference. ʻO ka nui o ke kamaʻilio kikowaena Serial a hiki i 921.6KBPS.

Nā hiʻohiʻona
- Ma muli o ka IC pono'ī
- Hiki ke ʻike a hoʻomalu i ka kahe ʻikepili RS-485 me ka ʻole o nā hōʻailona lulu lima e hoʻomalu i ke ala kahe o ka ʻikepili
- Loaʻa i ka hiki ke ʻike pono i ka baud rate o ka hōʻailona port serial
- E hoʻāʻo ʻokoʻa i ke kumu o ka mīkini matt no ka pau ʻana o ka mana, a i ʻole ua haki ka laina E1. A laila e hōʻike i ka LED
- Hāʻawi i 2 impedances: 75 Ohm unbalance a me 120 Ohm kaulike;
- Kākoʻo iā SNMP Network Management
- Hiki i ke kaila Serial ke hoʻouna i ka ʻikepili serial hiki ke hoʻololi like ʻia me 300 Kbps-921.6Kbps baud rate
- Kākoʻo ka hoʻonui ʻana i ka ʻikepili Serial ma E1 i ka ITU-T R.111 lele lele ʻana
- Serial port interface uila-pale i hiki i IEC61000-4-5 (8/20μS) DM(Differential Mode): 6KV,Impedance (2 Ohm), CM(Common Mode): 6KV, Impedance (2 Ohm) standard
