The receiving status information displays the on/off button, and the long press button can switch the switch status, and the switch status will be powered off. When the reception status information display is turned on, it is displayed in red in the upper left corner of the output video screen:- RF:338.0BW MHz:4.0MHz
QPSK CR:2/3 GI:1/16
HUAB CUA:3.90Mbps
VBR:3.05Mbps AES tawm
SIG1:27 SIG2:22
ber1:0.14% ber2:100.00%
Tim REC tawm tsis cia - RF indicates the center operating frequency, thiab BW indicates the working bandwidth.
QPSK is the modulation mode, CR yog lub chaws convolutional, thiab yog tus ceev xwm yuav luv GI.
HUAB CUA is the air interface rate
VBR is the video bitrate, AES OFF means no encryption
SIG1 refers to the received signal strength near the HDMI port antenna, thiab SIG2 refers to the other antenna.
Ber1 refers to the BER error rate near the HDMI port antenna, thiab ber2 refers to another antenna.
REC OFF means no video storage
- RF:338.0BW MHz:4.0MHz
- When the wireless receiving signal is interrupted or weak, yuav tu ncua qhov zis video screen yuav (qhov tshuaj ntsuam teeb liab tsawg zaus rov yuav yuav yuav huv), and display: Disconnected, tsis muaj teeb liab
- REC button: Video recording on/off button, short press button to switch state, start recording after power is detected. The system defaults to recording to the TF card. Yog tus TF daim ntawv no tsis tso, Nws yog kaw cov USB flash tsav. Yog hais tias lawv yeej tsis tso, lawv yuav tsis raug kaw.
- Txuas qhov taw qhia tau hais tias: The wireless receiving link working status indicator lights up after the system is started and blinks when the receiving signal is normal.
- REC indicator: The video recording indicator will flash at the low frequency when recording video, otherwise the high frequency will flash.
- PWR indicator: Qhov taw qhia fais fab.
- CFG serial port: Parameter configuration Serial port, you can configure wireless receiving related parameters, xws li qhov chaw ua hauj lwm frequency, wireless bandwidth, decryption password, thiab lwm yam. Vcan provides a matching parameter configuration panel SconB to facilitate user parameter setting.
- Data serial port: Pob tshab ntawv kis serial chaw nres nkoj. The serial port data of the transmitter can be wirelessly transmitted to the receiver and output from the serial port.

Ceeb toom
Thaum lub COFDM-905T transmitter and receiver COFDM-905T tsim ib qhov system point-to-point video wireless kis, qhov qhia tau qeeb video:
Peb indicators as video qeeb, tus nqi ntsis video, thiab cua interface tus nqi yog kev sib nrig sib thiab kev sib nrig sib khi. Thaum cov pa interface yog siab tshaj 5 lub sij hawm cov video chaws twg, lub qeeb video no yam tsawg kawg nkaus. Qhov no, qhov kev kuaj ntawd sij yog tias cov video ncua yog hais txog 60 milliseconds thaum qhov chaws yog kis ntawm 720P@60, thiab cov video ncua yog hais txog 130 milliseconds ntawm 1080P@60. Lub qeeb hais txog qhov ncua ntawm cov HDMI video input kis kawg rau qhov HDMI video tso zis ntau kawg tau nyiaj, excluding tus ncua ntawm cov koob yees duab front-end txog tag kis (peb li qeeb rau ntawm ib hom SLR yees thaum txog 70 milliseconds, thiab qhov ncua ntawm ib tug naas ej hom kev ua si lub koob yees duab ntawm txog 130 milliseconds). Rau feem ntau cov ntawv scenarios, cov video qeeb yog teem rau 200ms li los vim.
Thaum lub COFDM-905T transmitter thiab cov COFDM-905R receiver tsim ib qhov system point-to-point video wireless kis, yuav kis tau tus mob ntawd:
Wireless kis tau tus mob ntawd muaj feem xyuam rau ntau yam xws li kuaj puag ncig, cuam Ambient electromagnetic, tej yam kev mob occlusion, pa av noo, ua hauj lwm zaus, wireless bandwidth, thiab kis thiab tau txais antennas. Cov kev ntsuas tau: ib tug neeg kuaj, unmanned aircraft-mounted ST100 transmitter to fly about 100 siab meters, koj muab tau 4M QPSK wireless bandwidth, 700MHz chaw kev khiav hauj lwm zaus, 1W kis fais fab, transmitter kav hlau txais xov 3dBi ib ncig, Tau muab iav fiber ntau kav hlau txais xov koj qhov nce ntawm txog 10dBi, the distance of up to 16km (yees duab du); peb muaj peb li kev kuaj hauv Shenzhen, community launch kawg rau qhov flyover, kav hlau txais xov hose zoo tib yam (hais txog koj qhov nce 3dBi), 340Community launch MHz, QPSK 8M Bandwidth, tus kav hlau txais xov fiberglass kawg tau nyiaj, thiab ib Yagi kav hlau txais xov, hais txog 2.2 meters loj rau ntawm tus ncej, 2.2 kilometers tseg, txhais yees duab du, Ib tug xov tooj ntawm high-sawv vaj tse ntawm tus transmitter thiab receiver, txoj kev mus txog visually 20 dabtsi yog khoov degrees. Vim muaj cai txwv tsis pub, tsis muaj kev xeem ntxiv tau ua.
