Thov modem cable: interface hauj lwm, muaj nuj nqi Thaiv

Manufacturers ntawm satellite receivers tseg tso tshiab rau lub software ntawm cov khoom, txhim kho kab nyob rau hauv nws, raws li tau zoo raws li zoo tuaj kawm los yog ntxiv ib co tshiab nta.

Yuav kom txawj tej yam ntxiv cov firmware, koj yuav tsum xub download tau rau koj lub PC, thiab ces txuas lub receiver rau cov PC thiab pib dua qhov kev pab cuam. Rau ib lub computer txuas mus rau ib tug receiver ntawm satellite Pib ntsais koj teeb siv ib tug thov modem cable. Yog hais tias koj tsis muaj xws li ib tug interface, nws yuav tsum tau muas ntawm feem ntau computer khw muag khoom noj, tab sis yog tsis ib txwm, cov khoom muaj. Nyob rau hauv txhua rooj plaub, koj muaj ib tug xaiv: mus nrhiav ib tug turnkey tshuaj los yog yuav ua ib tug thov-modem cable koj tus kheej. Cov yav tas kev xaiv no yog cheaper npaum li.

Yuav ua li cas yuav ua rau ib tug thov-modem RS-232 cable?

Rau nws cov ntau lawm, peb yuav tsum tau tus plaub-core cable (ntev txiav txim los ntawm tus neeg siv) thiab ob RS-232 connector hom ( "niam"). Cov connectors yuav muaj nyob rau hauv tej xov tooj cua, lawv yog heev nrov, raws li yog tam sim no nyob rau hauv yuav luag txhua txhua tus kheej lub computer raws li lub COM chaw nres nkoj. Cable yuav pab raws li ib tug cov khub. No cov ua ke txhua lub cores thiab tau txais cov plaub conductors. Tom ntej no, koj yuav tsum tuav connector pinout. Nws yog tsim nyog los tiv thaiv kom txhob lo Circuit Court, raws li nws yuav coj mus ua hauj lwm ntawm cov khoom siv. Xws li ib tug thov modem cable Nws yuav ua hauj lwm stably nrog cov hlau ntev ntawm 50 meters.

Pom zoo rau soldering

Txoj kev qhia no tsis yog yuav tsum tau, tab sis nws yog mus soj ntsuam nyob rau hauv kev xyaum:

1. Tsis txhob xa daim ntawv tseg cov neeg ntxiv pins rau connectors.

2. Ib tug compound connector housings xav tau rau kev nyuaj siab relieving, t. K. Nrog kev xav txog cov ntaus ntawv lub cev. Txwv tsis pub muaj ib tug uas yuav mus hlawv cov COM interface rau hauv lub computer los yog receiver. Qhov no compound yog tsis tsim nyog, yog hais tias tag nrho cov khoom yog grounded.

3. Dua li siv ib tug shielded cable, vim hais tias nws ua hauj lwm zoo dua.

4. Nyob rau hauv tag nrho cov tuners satellite teeb liab yog tsuas yog peb hu.

5. Nyob rau hauv ib co receivers tsis muaj MAH232 chips (piv txwv tias yog tias nws yuav tsum tau nyob rau hauv lub sab nraud adapter). Nyob rau hauv xws li nyob rau hauv lub COM chaw nres nkoj lub receiver plaub outputs yog muab kev koom tes, Txawm li cas los, tso zis rau ntawm lub adapter - tib yam peb pins. Yog li ntawd, ua ntej koj cuag ib tug thov modem cable, koj yuav tsum mus kawm nyob rau hauv kom meej cov ntaub ntawv rau koj ntaus ntawv yuav thawj zaug yuav tsum tau muab lub adapter.

6. Nyob rau hauv ib co tuners pins 2 thiab 3 rau ntawm lub connector sib puav. Nyob rau hauv cov ntaub ntawv no, koj yuav xav tau ib tug ncaj los ntawm cable, tsis yog ib tug crossover. Nyob rau hauv kev txiav txim los mus txiav txim yog dab tsi hom connector yog sawv nyob rau hauv koj receiver, koj yuav tsum xav txog nws cov ntaub ntawv.

7. Lub tso tseg cable pom zoo rau siv, vim nws yog ntau resistant rau cov neeg kho tshuab kev nyuaj siab. Soldered hu yog zoo dua rau sau nrog silicone nyob rau hauv kev txiav txim kom tsis txhob luv luv-Circuit Court.

Thaiv RS232 thov-modem cable

Lub COM interface yuav tsum solder tag nrho peb muaj mob thiab cov connector vaj tse nyob. Nyob rau hauv xws li ib tug cable yog tsim nyog los siv 2, 3 thiab 5 muaj mob. Nyob rau hauv lub embodiment, qhov ncaj thov modem cable ntaub ntawv hu yog soldered nyob rau hauv tib txoj kev ob leeg connectors thiab crosswise 2 thiab 3 yog interchanged.
