Mawonekedwe abwino kwambiri a Rs485 mpaka Rs232 seri Converter - Mawonekedwe a E1-FE+8RS232 osinthira JHA-CE1F1R8 - JHA

Yopangidwa ndi E1-FE+8RS232 mawonekedwe osinthira JHA-CE1F1R8

Mwachidule

Protocol converter (interface converter) pogwiritsa ntchito mapangidwe akuluakulu a FPGA, kupereka mawonekedwe a E1 ndi mawonekedwe a Efaneti ndi 8channel RS232/422/485, ndizotheka kukwaniritsa 10/100Base-T Efaneti deta pa E1 njira kufala, ndi mkulu magwiridwe antchito, kuphunzira paokha Ethernet mlatho. chipangizo akutumikira monga kutambasuka Efaneti zipangizo, ntchito maukonde alipo (PDH / SDH / mayikirowevu, etc.) operekedwa ndi njira E1 kuti interconnect malekezero onse a mtengo wotsika Efaneti ndi mawonekedwe siriyo. Kuthekera kwa zida zoyeserera zoyeserera kuti zithandizire kutsegulira komanso kukonza nthawi zonse.

Mawonekedwe

• Kutengera kudzikonda kwa IC
• Itha kuzindikira kuwunika ndikuwongolera zida zakutali, data yoyang'anira OAM sinatenge nthawi ya ogwiritsa ntchito ndikusunga bandwidth ya E1
• E1 imathandizira nthawi iliyonse, mtengo wake ndi 64K-2048K
• The chipangizo m'deralo akhoza kukakamiza kutali chipangizo mlingo kutsatira izo
• Khalani ndi chizindikiro pamene chipangizo chakutali chikuzimitsa kapena mzere wa E1 wathyoka kapena kutaya chizindikiro;
• Khalani ndi ntchito ya E1 mawonekedwe loop kumbuyo cheke, pewani chosinthira chikasokonekera chifukwa cha mawonekedwe a loop kubwerera;
• Mawonekedwe a Efaneti amathandizira mafelemu a jumbo (2036 Bytes);
• Ma Inter-set dynamic Ethernet MAC adilesi (4,096) yokhala ndi ntchito yosefera yam'deralo
• Efaneti mawonekedwe amathandiza 10M/100M, theka/full duplex auto- Negotination, thandizo VLAN
• Mawonekedwe a Efaneti amathandizira AUTO-MDIX (mzere wowoloka komanso wolumikizidwa molunjika wodzisintha);
• Khalani ndi Ethernet yowunikira ntchito yodzikonzanso, zida sizidzafa
• Perekani mitundu iwiri ya wotchi: E1 master wotchi ndi E1 mzere wotchi;
• Perekani 2 zolepheretsa: 75 Ohm kusalinganika ndi 120 Ohm balance;
• Thandizani SNMP Network Management
• Seri Data Interface ikhoza kukhala RS232/RS422/RS485/TTL mwakufuna
• Njira yotsatsira imatha kufalitsa deta yosinthika mosiyanasiyana 300 Kbps-19200Kbps baud rate
• Siri data multiplexing mu E1 kuthandizira ITU-T R.111 kudumpha code code
• Zambiri zam'deralo za RS232 zimatha kulamula zakutali za RS232 serial data loop-back to local. Kuzungulira uku mu mphete yakunja ya mawonekedwe a data a RS232, mutha kuyesa mawonekedwe a RS232 chip popanda kuwonongeka.
• 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) mulingo
