Receiver LCD parameter description

2. Functional Area Description

1. CH01 KİLİTLİ （LCKLİ）
   • “CH01” is the receiver channel number, “KİLİDİ ​​AÇIK” is the receiving signal that is not locked, ve “LCKED” is the signal that is locked. “CH00” of the receiver is the starting writing channel, ve vericinin normal çalışmasına karşılık gelen varsayılan kanal “CH001”
2. FREKANS：602.0MHz

3. siyah beyaz:6.0MHz
   • “siyah beyaz” bandwidth, şekilde gösterildiği gibi, “siyah beyaz: MHz” is understood to mean that the radio frequency bandwidth is 6MHz (default is 2MHz). This bandwidth must be consistent with the bandwidth set by the transmitter, aksi takdirde, the receiver will search for or cannot receive the transmitter signal.
4. FEC:1/2
   • “FEC:1/2” is channel error correction. This parameter synchronizes the transmitter setting parameters and cannot be modified by the receiving end.
5. GI:1/32
   • “GI:1/32” kanal koruma aralığıdır. This parameter synchronizes the transmitter setting parameters and cannot be modified by the receiving end.
6. HARİTA: QPSK
   • “HARİTA: QPSK” modülasyon eşlemesidir. This parameter is synchronized with the transmitter setting parameters and cannot be modified by the receiving end.
7. SNR: 0.0dB(SNR:15.0dB)
   • “SNR:15.0dB” sinyal kalitesi (yani. sinyal-gürültü oranı, değer ne kadar büyükse, daha iyi). Ne zaman “0.0dB” görüntüleniyor, sinyal kalitesi 0, ve alıcı kilitlenemeyecek.
   • “(SNR:15.0dB)” alma sinyali-gürültü oranının 15dB'den büyük olduğu anlamına gelir. içinde “QPSK” modülasyon eşleme durumu, the receiver can lock as long as the signal-to-noise ratio is greater than 6dB.
8. Şifre：-72.1dBm（PW:-72.1）
   • PW alınan sinyal gücüdür, (referans seviyesi değeri). The farther away the receiving end is from the receiving end, the weaker the signal strength, and the larger the displayed value. When the transmitter is not turned on, alıcının sinyal gücü -90dBm'den büyükse (-79,7dBm gibi), bitişik frekans girişimi olarak düşünülebilir

Receiver Parameter configuration description

Turn on the power of the receiver and press the “MENÜ/OK” menüye girmek için düğmeye. The menu with adjustable parameters is first displayed. If you want to search for a specified frequency, tuşuna basın “MENÜ/OK” menüye girmek için düğmeye. If you need to remove a channel, press the down button to select “ListanbulKanal”, and then press the “MENÜ/OK” button to enter the menu operation; if you need to save the current channel, basmak “MENÜ/OK” at the same time and right-click to confirm the save.

Frekans arama yöntemi aşağıdaki gibidir. Frekans ayar menüsüne girdikten sonra, arayüz şekilde gösterildiği gibi görüntülenir. Press the left or right button to move the cursor, press the up or down button to adjust the frequency, radio frequency bandwidth, ve vericiyle eşleşen gizli anahtar. Basmak “MENÜ” /TAMAM” key to search. Vericinin bu sırada açık olması gerektiğini unutmayın., otherwise the receiver will not be able to lock because it cannot search for signals.

Arama tamamlandığında, basmak “MENÜ/OK” onaylamak. Şu anda, the channel is saved in the parameter adjustment board register, şekilde gösterildiği gibi. If you need to save the channel to the receiver register, tuşuna basın “MENÜ/OK” anahtar ve sağ tuş aynı anda.

Alıcı parametre ayarı tamamlandıktan sonra, the panel button functions are as follows:

Micro COFDM Video Transmitter and Receiver Typical troubleshooting

Fault phenomenon	Çözüm
No image, ses yok	1. Check whether the transmitter battery is charged and whether the transmitter indicator light is normal. Pay special attention to the distance and wiring pattern of the transmitter video cable and power cable from the antenna. 2. Check whether the camera battery is charged, whether the audio and video cable has been connected to the transmitter, and whether the camera is in standby mode. 3. Check whether the receiver antenna is connected properly and whether the antenna connector is wet or loose. 4. Check whether the monitor audio and video cables are connected properly and whether the startup screen is normal. 5. Check the frequency settings, and whether the frequency settings for transmitting and receiving are the same. 6. Check the electromagnetic environment to see if there is interference from same-frequency signals nearby
The receiver has no picture, but the sound is normal	1. Check whether the video cables of the camera and transmitter are connected properly 2. Check whether the video cable between the receiver and the PC is properly connected
No sound or noise from the receiver but the normal picture	1. Check whether the audio cables of the camera and transmitter are connected properly. 2. Check whether the audio cable between the receiver and the TV or audio output device is properly connected.
The image is continuous, then pauses, and a black screen appears.	1. The signal is not good, which is normal. 2. Whether the signal quality display on the LCD screen on the receiver keyboard is normal, and whether the parameter value fluctuates greatly (bundan fazla 10). If so, it means there is some frequency interference.
Coverage suddenly becomes smaller	1. Check whether the transmitting antenna and receiving antenna are connected properly and whether there is water or poor contact 2. Check whether the power supply voltage of the transmitter is normal. 3. Check the surrounding environment for electromagnetic interference from signals of the same frequency.
The coverage is small and the transmission distance is not far enough	Check the installation position of the receiving antenna, increase the height of the receiving antenna, and use high-gain omnidirectional and directional antennas and diversity reception if necessary
There is image and sound, but the image is blurry	Check whether the camera at the front end of the transmitter is focused accurately and whether the autofocus function setting is turned on.
