Ntau qhov ua tsis tiav ntawm cov xim puv xim LED yog tshwm sim los ntawm kev teeb tsa tsis raug.Yog li ntawd, cov kauj ruam yuav tsum tau ua raws li nruj me ntsis raws li cov txheej txheem installation, tshwj xeeb tshaj yog thaum lub sij hawm thawj installation.Txhawm rau txo qhov tshwm sim ntawm qhov yuam kev, cia peb saib tag nrho cov xim LED.Daim duab kab hluav taws xob ntawm lub vijtsam zaub thiab cov txheej txheem thaiv cov kauj ruam rau kev teeb tsa cov xim puv xim LED.

1. Tag nrho-xim LED zaub cable txuas daim duab

Ob, txheej txheem txheej txheem

1. Xyuas seb lub hwj chim mov voltage ntawm cov xim puv xim LED yog qhov qub.

Nrhiav cov khoom siv hluav taws xob hloov pauv nrog qhov zoo thiab qhov tsis zoo DC kev sib txuas, txuas 220V lub zog hluav taws xob rau lub zog hloov hluav taws xob, (kom paub tseeb tias nws txuas raug raug, txuas AC lossis NL lub davhlau ya nyob twg), thiab txuas lub zog hluav taws xob.Tom qab ntawd siv multimeter thiab DC hom los ntsuas qhov voltage los xyuas kom meej tias qhov hluav taws xob nyob nruab nrab ntawm 4.8V-5.1V, thiab muaj lub pob qhov rooj ntawm ib sab, uas tuaj yeem hloov kho los ntawm Phillips ntswj ntsia hlau, thiab DC hom yog siv los ntsuas qhov ntsuas. hluav taws xob.Txhawm rau txo cov cua sov ntawm lub vijtsam thiab ua kom nws lub neej ntev, qhov hluav taws xob tuaj yeem hloov kho mus rau 4.5V-4.8 qhov twg qhov kev xav tau ci ntsa iab tsis siab.Tom qab paub tseeb tias tsis muaj teeb meem nrog qhov voltage, txiav tawm lub hwj chim mov thiab txuas ntxiv mus sib sau ua ke lwm qhov chaw.

2. Tua lub zog ntawm cov xim puv xim coj zaub.

Txuas V + mus rau cov xaim liab, V + rau cov hlau dub, feem txuas cov xim puv xim LED zaub tswj daim npav thiab LED vaj huam sib luag, thiab cov hlau dub rau daim npav tswj thiab GND fais fab mov.Liab txuas daim npav tswj hwm + 5V voltage thiab chav tsev board VCC.Txhua lub rooj tsavxwm muaj ib txoj hlua.Thaum koj ua tiav, xyuas tias kev sib txuas yog lawm.

3. Txuas tag nrho-xim coj zaub maub los thiab lub rooj tsavxwm.

Siv cov kab hluav taws xob zoo thiab kev sib txuas.Thov xyuam xim rau cov kev taw qhia thiab tsis txhob thim rov qab kev sib txuas.Cov xim puv xim coj zaub vaj huam sib luag muaj ob 16PIN interfaces, 1 yog cov tswv yim, 1 yog cov zis, thiab thaj tsam ntawm 74HC245/244 yog cov tswv yim, thiab daim npav tswj tau txuas nrog cov tswv yim.Cov zis yog txuas nrog cov tswv yim ntawm lub rooj tsav xwm tom ntej.

4. Txuas RS232 cov ntaub ntawv kab ntawm cov xim puv xim LED.

Txuas ib kawg ntawm cov ntaub ntawv cable mus rau lub computer lub DB9 serial chaw nres nkoj, thiab lwm yam kawg mus rau tag nrho-xim coj zaub tswj daim card, txuas 5 tus pin (xim av) ntawm DB9 rau GND ntawm daim npav tswj, thiab txuas 3. tus pin (xim av) ntawm DB9 rau kev tswj RS232-RX ntawm daim npav.Yog tias koj lub PC tsis muaj qhov chaw nres nkoj serial, koj tuaj yeem yuav USB rau RS232 serial chaw nres nkoj hloov dua siab tshiab cable los ntawm Computer Store.

5. Txheeb xyuas qhov kev sib txuas ntawm cov xim puv xim coj rov qab.

Txawm hais tias cov hlau dub raug txuas nrog -V thiab GND, thiab cov xaim liab txuas nrog +V thiab VCC + 5V.

6. Qhib lub 220V fais fab mov thiab qhib lub software downloaded los ntawm cov zaub puv xim LED.

Feem ntau, lub teeb hluav taws xob yog qhib, daim npav tswj tau qhib, thiab cov xim puv xim LED qhia nws.Yog tias muaj dab tsi txawv txav, thov xyuas qhov txuas.Los yog xyuas kev daws teeb meem.Teem screen parameters thiab xa subtitles.Thov xa mus rau cov lus qhia software.
