2019 Mtundu wapamwamba kwambiri Rs232 mpaka Rs485 - 4E1-4FE Interface Converter JHA-CE4F4 (Logical lsolation) - JHA

Mwachidule

Kusintha kwa mawonekedwewa kumakhazikitsidwa ndi FPGA, pogwiritsa ntchito ukadaulo wa reverse direction multiplexing kuti mulunjike mabwalo angapo a E1 kuti atumize data ya Ethernet ya 4Channel 100BASE-TX. Itha kuzindikira 1 ~ 4 E1 njira yosinthira pakati pa mawonekedwe a Efaneti. Chipangizochi chimatha kutumiza chizindikiro cha transceiver kuti chiloze ku mawonekedwe a Efaneti kuti apange njira za E1 zolumikizidwa ndi mawonekedwe a Ethernet optical. Mosiyana ndi mlatho wakutali wakutali, chipangizochi chimatha kuthandizira kasinthidwe ka tchanelo cha 1-4Channel E1, chitha kuzindikira nambala ya E1 ndikusankha E1 yomwe ilipo. Iwo amalola E1 mizere kufala nthawi kuchedwa kusiyana.

Mawonekedwe

• Kutengera kudzikonda kwa IC
• Kukwaniritsa Efaneti deta mandala kufala mu 1-4E1 mabwalo
• Itha kuzindikira zakukhazikitsanso chipangizo chakutali komanso chakutali
• Ethernet Interface ndi 100BASE-FX, imathandizira protocol ya VLAN
• Ma Inter-set dynamic Ethernet MAC adilesi (4,096) yokhala ndi ntchito yosefera yam'deralo
• Single Channel mizere mizere ndi 1984Kbit/s, 4Channel Bandwidth mpaka 7936Kbit/s
• Mawonekedwe a Channel 10M/100M Ethernet amatha kudzipatula kuti azitha kulumikizana paokha
• Mawonekedwe a Efaneti amathandizira 10M/100M, theka/full duplex auto- adaptable and AUTO-MDIX (wowoloka mzere wolumikizidwa mowongoka wodzisinthira nokha)
• CRC automatic alarm threshold imatha kukhazikitsidwa kuti isiyanitse mizere yopatsirana yabwino ndikudula njira imodzi. Pamene 2M nthambi dera onedirection cholakwa chiwongolero chikudutsa pakhomo, kudula mbali iyi mbali ina sikukhudzidwa; ndiye kuti, onse a Ethernet directiontransmission akhoza kukhala asymmetric
• Lolani 4-Channel E1 kufala nthawi kuchedwa kusiyana 100ms. Mphepete mwa malire ikadutsa malire ololedwa, makinawo amatha kuyimitsa pa E1 kuti kuchedwa kwa nthawi kumakhala kwakukulu kwambiri kutumiza deta
• Mawonekedwe a E1 amagwirizana ndi ITU-T G.703, G.704 ndi G.823, osachirikiza kugwiritsa ntchito chizindikiro chanthawi
• E1 mawonekedwe gawo ndi inter-set wotchi kuchira dera ndi HDB3 code dera
• Thandizani njira yotentha ya E1 pa chipangizocho, ndikuzindikira zokha njira ya E1 yogwira mtima ndipo sikusokoneza kutumiza kwa data.
• Itha kuthandizira kasinthidwe ka 1-4Channel E1, imatha kuzindikira nambala ya E1 ndikusankha E1 yomwe ilipo;

Zofotokozera

Kugwiritsa ntchito

Kufotokozera za ntchito:

Pamene chipangizo anapereka zomveka kudzipatula , angapezeke Independent kulankhulana pakati A - A1, B - B1, C - C1 ndi D - D1.
1. Zosintha za Protocol zimagwiritsidwa ntchito pawiri;
