4: Imiyalo yokusetshenziswa
1: Transmitter
- Incazelo yendawo esebenzayo
“ANT”: Idlulisa isixhumi esibonakalayo se-antenna, sicela uxhume uthi ngaphambi kokuvula
“HDMI”: Isixhumi esibonakalayo sevidiyo enencazelo ephezulu, okokufaka okungaphansi kuka-1080/50P
“Ctrl”: Isixhumi esibonakalayo sokuxhuma kweshuna yokudlulisa
“DC 12V”: Imbobo yokufaka amandla ye-DC12V. “+” is the positive pole of the power supply, “-” is the negative pole of the power supply
“DC” is: Isibani senkomba yamandla, lapho ukukhanya kuhlala kuvuliwe, kusho ukuthi okokufaka kwamandla kwemojula yokudlulisa kujwayelekile
“TS”: Isibani sesikhombi sokubona okokufaka kwevidiyo, lokhu kukhanya kuhlala kukhanya ukuze kubonise okokufaka kwevidiyo kanye nombhalo wekhodi ovamile
- Incazelo Yokucushwa Kwepharamitha
Xhuma isilungisi sepharamitha ye-transmitter, press the “MENU/OK” key to enter the menu, ukhiye wokubethela kanye namapharamitha wembobo yedatha aboniswa kuqala, cindezela inkinobho yesokunxele noma yesokudla ukuhambisa ikhesa, kanye nokhiye baphezulu naphansi ukulungisa amapharamitha
Ngemva kokuthi ukulungiselelwa kwepharamitha kuqediwe, press “MENU/OK” to enter the next menu, futhi isikhombimsebenzisi siboniswa njengoba kukhonjisiwe emfanekisweni
Cindezela inkinobho yesokunxele noma yesokudla ukuhambisa ikhesa, cindezela inkinobho ethi phezulu noma phansi ukuze ulungise imingcele edingekayo, i-interface ikhuthaza njengoba kuboniswe esithombeni
Ngemuva kokuthi zonke izilungiselelo zepharamitha seziqediwe, press the “MENU/OK” key to confirm, futhi isibonisi sizoba njengoba kuboniswe esithombeni.
Ngemva kokuqedwa kokusetha, amapharamitha abhalwe ngempumelelo, futhi isibonisi sinjengoba kukhonjisiwe esithombeni
- Ukuxazulula Inkinga Okujwayelekile
a: Isibani sicishiwe ngemva kokuba amandla evuliwe: Hlola ukuthi okokufaka kwamandla kuyahlangabezana yini nendinganiso
b: “TS” indicator light is off: Hlola ikhebuli yokuxhuma yokufaka ividiyo, hlola ukuthi ifomethi yokufaka ividiyo iyahambisana yini, futhi uhlole ukuthi ikhamera iphazamisekile yini (ungahlulela ngokubamba uthi ngesandla).
C: Izinga lokushisa le-transmitter liphansi kakhulu: hlola ukuthi i-current ijwayelekile yini (ukuchezuka kungaba ngu-±0.2A ngaphakathi kwesilinganiso samanje).
d: Izibani ezintathu zihlala zikhanya, futhi enye yazo igqame kakhulu: kusho ukuthi umthumeli wehlulekile ukutholwa, futhi ungazama ukucisha bese uqala kabusha (okungajwayelekile)
2: Receiver
- Incazelo yendawo esebenzayo
“RF in1” “RF in2”: ithola isikhombimsebenzisi se-antenna, kunconywa ukuthi uxhume uthi bese uvula iswishi yamandla, ngoba ugesi omile womzimba womuntu ungase ubangele ukuba umamukeli aphahlazeke.
“HDMI”: Isixhumi esibonakalayo sevidiyo, the output video format can be adjusted through the “HDMI” menu on the control panel.
“DC 12V”: esibonakalayo Amandla okokufaka, sicela ulandele ngokuqinile izidingo zamandla kagesi, kanye nokufakwa kwe-overvoltage kunqatshelwe ngokuphelele
“ON/OFF”: ukushintshwa kwamandla.
“USB”: isikhombimsebenzisi sesitoreji sevidiyo, uma i-U disk ifakiwe, press the “EXIT” button to start the video recording, ngemva kokuba ukurekhoda kube yimpumelelo, isibonisi sevidiyo sizobonisa isikhathi sokuqoshwa kwevidiyo, and the stored file name is “TS”.
- Incazelo yepharamitha ye-LCD
a：CH01 UNLOCKED（LCKED）
“CH01” means the channel number of the receiver, “UNLOCKED” means the received signal is unlocked, and “LCKED” means the signal is locked. “CH00” of the receiver is the initial writing channel, and the default channel corresponding to the normal operation of the transmitter is “CH001”
b： FREQ：602.0MHz
“602.0MHz” is the receiving frequency of the receiver, this frequency must be consistent with the frequency set by the transmitter, otherwise the receiver will not search or receive the signal from the transmitter
c： BW:6.0MHz
“BW” bandwidth, as shown in the figure, “BW: MHz” is understood as the RF bandwidth is 6MHz, this bandwidth must be consistent with the bandwidth set by the transmitter, otherwise the receiver will search for or cannot receive the signal from the transmitter
d： FEC:1/2
“FEC: 1/2” is the channel error correction, this parameter synchronizes the parameters set by the transmitter, and the receiver cannot be modified
e： GI:1/32
“GI:1/32” is the channel guard interval, this parameter is set by the transmitter synchronously, and the receiver cannot be modified
f:IMAP: QPSK
“MAP: QPSK” is the modulation mapping, this parameter number is set by the transmitter synchronously, and the receiver cannot be modified
g： I-SNR:0.0dB(I-SNR:15.0dB)
“SNR: 15.0dB” is the signal quality (leyo, the signal-to-noise ratio, the larger the value, the better). When “0.0dB” is displayed, the signal quality is 0, and the receiver will not be able to lock
“(I-SNR:15.0dB)” means the receiving signal-to-noise ratio is greater than 15dB. In the “QPSK” modulation mapping state, as long as the signal-to-noise ratio is greater than 6dB, the receiver can lock
h: PW：-72.1dBm（PW:-72.1)
PW is the received signal strength, (reference level value), the farther the transceiver end is relative to the distance, the weaker the signal strength is, and the larger the displayed value is, when the transmitter is not turned on, if the signal strength of the receiver is greater than -90dBm (such as -79.7dBm), it can be considered as adjacent frequency interference
- Incazelo Yokucushwa Kwepharamitha
Power on the receiver, and press the “MENU/OK” button to enter the menu, the first display is the menu of adjustable parameters, if you search for a specified frequency, directly press the “MENU/OK” button to enter the menu; if you want to remove the channel, press Press down to select “ListanbulChannel”, and then press “MENU/OK” to enter the menu operation; if you need to change the video output format, move the cursor to the “HDMI Mode” menu, press “MENU/OK” to enter, and select the video to be output After formatting, press the “MENU/OK” key to confirm.
The frequency search method is as follows. After entering the frequency setting menu, the interface is displayed as shown in the figure. Cindezela inkinobho yesokunxele noma yesokudla ukuhambisa ikhesa, press the up or down key to adjust the frequency, RF komkhawulokudonsa, kanye nokhiye oyimfihlo ohambisana nesithumeli, and press the “MENU /OK” key to search. Qaphela ukuthi isidlulisi kufanele sivulwe ngalesi sikhathi, kungenjalo, umamukeli ngeke akwazi ukukhiya ngoba akakwazi ukuthola isignali.
I-COFDM Mobile Video Wireless Transmission enenani eliphansi ihlanganisa isidlulisi kanye nomamukeli we-China ngokuqondile
Uma ukusesha kuqediwe, press “MENU/OK” to confirm, futhi isiteshi sigcinwa kurejista yebhodi lomsizi, as shown in the figure. Ukugcina isiteshi kurejista yomamukeli, press the “MENU/OK” key and the right key at the same time.
Ngemva kokuqedwa kokusetha ipharamitha yomamukeli, imisebenzi yokhiye bephaneli imi kanje
“↑”“↓“: each individually selectable receiver channel “CH**”
“←”“→“: Ungakhetha ukubuka imingcele efihliwe yomamukeli
“EXIT”: qala futhi umise ukuqopha
- Umsebenzi wevidiyo
Insert the storage device into the “USB” interface of the receiver, press the “EXIT” button to start recording, futhi ibhokisi lesikhathi sokurekhoda eliluhlaza lizovela ekhoneni eliphezulu kwesokunxele lesibonisi sevidiyo njengoba kukhonjisiwe ngezansi
- Ukuxazulula Inkinga Okujwayelekile
a: The value after the receiver displays “-” is very low (I-Tx ayivuliwe): Kusho ukuthi isiteshi samanje sinokuphazamiseka okukhulu kwe-electromagnetic, futhi inani elivamile li -90- -100.
b: Ayikwazi ukurekhoda ividiyo: hlola i-U disk noma shintsha i-U disk.
C: Ayikho isignali etholiwe: Hlola ukuthi imvamisa yesiteshi iyahambisana yini nesithumeli.
d: Akukho okukhipha ividiyo: Hlola umugqa wokuxhuma, vala amandla, bese uqala kabusha ukuze uhlole ukuthi asikho yini isixhumi esibonakalayo sokuqalisa.
