USB-COM adapter nrog koj ob txhais tes: lub tswvyim. Yuav ua li cas los xaiv tus USB-COM adapter

COM USB adapter - ib tug ntaus ntawv uas tso cai rau ib tug PC mus txuas rau ntau yam peripherals. Tu siab, tam sim no ua qauv ntawm lub system blocks tsis tej zaum tseem ceeb heev outputs. Yog li, tus neeg siv muaj kev txwv rau nws cov tuition.

Yog hais tias peb xav txog ib tug ntaus ntawv xws li ib tug receiver, nws yuav tsis tau txuas mus rau lub cable. Nyob rau hauv cov ntaub ntawv no, tus neeg siv yuav tsum tau los pab xwb lub adapter (adapter). Los ntawm hom connector cov ntaub ntawv ntaus ntawv sib txawv. Nyob rau hauv tas li ntawd, nws yuav tsum tau muab sau tseg uas yuav ua rau lawv nyob rau hauv tsev yog heev tiag. Ua ntej, txawm li cas los, nws yog ib qho tseem ceeb los ua me ntsis txog cov lawv ntaus ntawv.

Daim duab ntawm ib tug yooj yim adapter

Tsav USB-COM adapter muaj xws li ib tug chaw nres nkoj, modulator, transmitter, thiab ib tug resistor. Nyob rau hauv tej rooj plaub, lub amplifier yuav muab tso nyob rau hauv tas li ntawd mus rau lub Rooj Tswjhwm Saib cov. Nyob rau hauv cov ntaub ntawv no feem ntau xaiv yog ib tug wired qauv. Resistors siv nyob rau hauv cov ntaub ntawv no tsuas yog tus qhib hom. Nws yog tsim nyog yuav ua tau kom cov kev txwv zaus ntawm tus dais. Yog li, lub teeb liab teb lub sij hawm yuav tsum nyob ib ncig ntawm 20 msec. Ntawm lwm yam, tus ntaus ntawv yuav tsum coj mus rau hauv tus account lub dav ntawm lub kis tau tus mob. Yuav kom nce no parameter modulators ntau cov kws txawj pom zoo kom tsuas siv ob-txoj kev.

Ib tug txheej txheem qauv ntawm hom

Ua ib tug hom A USB-COM adapter nrog lawv ob txhais tes heev tsuas nyob rau hauv tsev. Nti nyob rau hauv cov ntaub ntawv no nws yog advisable mus xaiv lub hom PP21. Tswj cov txheej txheem nyob rau hauv lub chav tsev yuav tsuas pab converter. Rau ib txwm lag luam tus qauv yuav tsum tau high-quality modulators. Rau hais tias chips nws yog tsim nyog los xaiv tsuas tsawg zaus hom. Tag nrho cov no yuav co tes ib lo lus teb kev xaiv kom nyob ib ncig ntawm 30 ms.

kuj kws txawj pom zoo kom siv muaj hwj huam transistors rau zoo dua tam sim no conductivity. Nyob rau hauv cov ntaub ntawv no, lawv yog yuam ua hauj lwm kom tsis txhob muaj voltage mas theem 3B. Nyob rau hauv Feem ntau, cov adapters yog zoo tagnrho rau tag nrho cov hom ntawm cov receivers. Nyob rau hauv tas li ntawd, lawv yuav tsum tau kev cob cog rua rau lub xov tooj cua connector hom SR101.

Ib tug mini-hom qauv

Adapters ntawm no hom muaj peev xwm txhawb ntau tswv yim. Yog tsis muaj lawv nws tsis yooj yim sua rau nteg cia converters. Tsis tas li ntawd yuav tsum khaws ib nti PP22 series. Tag nrho cov transistors yuav tsum tau muab tso rau hauv nws peb. Nyob rau hauv cov ntaub ntawv no, ob leeg yuav tsum tau muab tso rau ze ntawm lub transmitter. Lub modulator nyob rau hauv cov ntaub ntawv no nws yog ib qho tseem ceeb los xaiv tus mem tes hom. nruab nrab teb tus nqi lub teeb liab yog kwv yees li 30 ms.
