Null modemu chingwe: kulongosola mawonekedwe, ntchito Kulumikizana

Opanga wa amalandira Kanema nthawi kumasula zosintha kuti mapulogalamu a zida, kukonza nsikidzi mmenemo, komanso bwino ntchito kapena anawonjezera zina zatsopano.

Sinthani ndi fimuweya, muyenera choyamba kukopera kwa PC anu, ndiyeno kugwirizana wolandila kwa PC ndi Chisudzulo Chikuwononga mwambowu. Kwa kompyuta chikugwirizana ndi wolandila wa chizindikiro Kanema ntchito null modemu chingwe. Ngati inu mulibe mawonekedwe zimenezi, zikhoza kugulidwa pa sitolo kwambiri kompyuta, ngakhale kuti nthawi zonse, mankhwala kumeneko. Mulimonsemo, inu muli nako kusankha: kufunafuna turnkey njira kapena kupanga null-modemu chingwe nokha. Njira yamasika mtengo kwambiri.

Kodi kupanga null-modemu RS-232 chingwe?

Kupanga ake, tiyenera zinayi pakati chingwe (kutalika anatsimikiza ndi wosuta) ndi awiri RS-232 cholumikizira mtundu ( "mayi"). zolumikizira amenewa amapezeka pa wailesi iliyonse, iwo ali otchuka kwambiri, monga alipo pafupifupi kompyuta yekha doko Com. Chingwe atha kutumikira ngati awiri zopotoka. Pakuti ichi wopota pamodzi aliyense wa mitima kuti apeze ochititsa anayi. Kenako, muyenera kugwira cholumikizira pinout. M'pofunika kuteteza dera mwangozi, monga kungachititse kuti kulephera kwa zipangizo. Chotero chingwe null modemu Ndi ntchito stably ndi waya kutalika mamita 50.

Malangizo kwa soldering

Lamuloli sikowumiriza, koma akuyesedwa mchitidwe:

1. Kodi si kupala kutali zikhomo anthu owonjezera pa zolumikizira.

2. A pawiri cholumikizira housings muyenera maganizo akuvutika, T. K. Pankhani thupi chipangizo. Apo ayi pali chiopsezo anatentha mawonekedwe Com pa kompyuta kapena wolandila. pawiri Izi Sikuti ngati zipangizo lonse chinakhazikika.

3. Amakonda ntchito chingwe isagwe, chifukwa amagwira ntchito bwino.

4. onse tuners Kanema mbendera ndi kulankhula atatu okha.

5. ena amalandira mulibe MAH232 tchipisi (poganiza kuti adzakhala ili mu adaputala kunja). Mu makina onga pa doko Com wolandirayo ndi zotuluka zinayi zokhudza Komabe, linanena bungwe la adaputala kwa - yemweyo zikhomo atatu. Choncho, musanayambe kugwirizana ndi null modemu chingwe, muyenera kuphunzira mwatsatanetsatane zolembedwa pa chipangizo chanu choyamba mungafunikire angagwirizanitse adaputala.

6. ena tuners zikhomo 2 ndi 3 pa cholumikizira sinthanani. Pankhaniyi, muyenera molunjika kudzera chingwe, osati kusinthanitsidwa. Pofuna kudziwa zimene mtundu wa cholumikizira waimirira wolandila wanu, muyenera kuonanso zolembedwa zake.

7. chingwe Shackleton akulimbikitsidwa kugwiritsa ntchito, chifukwa kwambiri kulimbana ndi maganizo makina. ojambula Soldered bwino kudzaza silikoni pofuna kupewa yochepa dera.

Kulumikizana RS232 null-modemu chingwe

The mawonekedwe Com ayenera solder kulankhula atatu ndi cholumikizira nyumba. Mu chingwe ndi zimenezi n'kofunika kugwiritsa ntchito 2, 3 ndi 5 ojambula. Mu chimake, ndi mwachindunji null modemu deta chingwe kulankhula ndi soldered chimodzimodzi zolumikizira ndi crosswise 2 ndi 3 ndi interchanged.
