Ndondomeko yowongoka RJ-45

Pali njira zosiyanasiyana zogwiritsira ntchito makompyuta ku intaneti, koma njira yowonjezera ikadali njira yogwiritsira ntchito luso la Ethernet, kutanthauza kugwiritsa ntchito awiri osokonekera. Pachifukwa ichi, chingwecho chikugwirizanitsidwa ndi khadi lachitetezo pogwiritsa ntchito chojambulira chapadera - RJ-45. Kenaka, tiwona m'mene crimp yowongoka imawonekera. Komabe, choyamba muyenera kukambirana za mapangidwe ake. Gulu lopotoka ndi limodzi kapena awiri ophatikizana a machitidwe opotoka, osakanikirana wina ndi mzake ndi ophimbidwa ndi pulasitiki. Kwa ife, ndiko kuti, kugwirizanitsa pa intaneti, chingwe chotchinga chimagwiritsidwa ntchito, chomwe chimaphatikizapo awiri awiri a ochita zoterezi.

Kenaka, muyenera kudziwa cholinga chomwe chidzagwiritsidwe ntchito musanagwirizanitse chojambulira. Pali mitundu iwiri yokonza mapulogalamu opotoka:
- kulumikiza - kugwirizanitsa makompyuta kumtundu wotambasula (kusinthana), mozembe kapena router;
- Cross (crossover) - kulumikizana makompyuta awiri mwachindunji wina ndi mnzake.

Ngati mukusowa dera lapadera kuti muzitha kupopera awiri ophwanyika, ndiye otsogolera pamapeto onse a chingwe ali motere:

Zikatero, ngati ndondomeko ya kupopera phokoso lopotoka idawoloka, makonzedwe a otsogolera adzasiyana:
Monga malamulo, makhadi a makompyuta amakono amadziwa "kumvetsetsa" ndi ndondomeko yolunjika pamene akugwirizanitsa ma PC awiri, koma tikulimbikitsanso kuti tiwagwirizanitse ndikugwirizanitsa nawo pogwiritsa ntchito mtanda.

Kotero, ndi motani momwe awiri ophwanyika amapotola? Kuti muchite izi, mukufunikira chingwe chomwecho, maulumikila awiri a RJ-45 (makamaka angapo) ndi apadera (kapena achifwamba) omwe ali ndi ntchito zitatu zomwe zimagwira ntchito zina. Chinthu chofunika kwambiri pa kapangidwe ndi mpeni, imene otsogolera amachotsedwa. Mitundu ina imakhalanso ndi chidziwitso chapadera chochotseratu kutsekera kunja kwa chingwe. Pakati penipeni pamalopo pali chingwe, chomwe chimagwiritsa ntchito mwachindunji kuti chikhomere. Ndipo, potsiriza, kumtunda pali malo apadera omwe amagwiritsidwa ntchito pochotsa kunja kwa awiri ophwanyika.

Choyamba, dulani mapeto a chingwecho ndi chingwe chodzimangira ndi kuvula masentimita angapo kuchokera pa kutsekemera ndi cholembera. Ngati simukupezeka, izi zingatheke mosavuta pogwiritsa ntchito mpeni kapena lumo. Kenaka, sungani, musamadziwike ndikugwirizanitsa awiriwa. Kenaka muwagawire iwo mu mitundu, monga momwe amasonyezera ndondomeko yofunira yopopera pakhosi lopotoka, ndi kuyanjanitsa. Limbani mwamphamvu ndi kumaliza mapeto awo ndi mpeni wakuwombera, kusiya asilimita 10 a oyendetsa zovala. Awaloweni mu chojambulira, onetsetsani kuti magawowo akhale pamapeto a zikhomo. Apanso, onetsetsani kuti oyendetsa bwino ali ndi maonekedwe abwino, amaika RJ-45 m'thuthu koyenera la mapulotechete ndi kuwombera m'manja mpaka malo otsekemera atha.

Komabe, zikhoza kuchitika kuti mulibe wachifwamba pafupi nanu. Pankhaniyi, gwiritsani ntchito wamba wonyezimira wowonda. Njira iyi ndi yowonjezera ntchito kwambiri komanso yosagwira ntchito, koma ikhoza kukhala yothandiza pazidzidzidzi. Kawirikawiri, ndondomekoyi ndi yofanana ndi yomwe yafotokozedwa pamwambapa. Kusiyana kokha ndiko kuti kuti muthe kuzungulira zida za RJ-45, mumayenera kuwapangira ndi nsonga ya screwdriver, yomwe imayendetsedwa, mpaka mano atuluke kwathunthu. Kulimbikira kumafunika kukhala olimba, komabe ndibwino.

Kuti muyese kayendetsedwe ka gulu lopindika lopindika pali chipangizo chapadera - LAN-tester. Komabe, nthawizina mungathe kuchita popanda izo - chifukwa choipa kapena chosagwira ntchito pamsewu zidzakwaniritsidwa kuti penapake panali kulakwitsa.

Tsono, tadzifufuzira awiri awiri opotoka, crimp ndondomekoyi, komanso zipangizo zomwe mungapangire chingwe. Monga mukuonera, ndondomekoyi ndi yosavuta ndipo safuna chidziwitso ndi luso lapadera - kulingalira chabe.
