6. USB interface:
   1. External phone or tablet can be used to output audio and video to mobile phone or tablet for decoding display
   2. Recording video can be connected to an external USB flash drive or USB hard disk
7. OSD button:
   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:
   1. RF：338.0MHz BW：4.0MHz
      QPSK CR：2/3 GI：1/16
      AIR：3.90Mbps
      VBR：3.05Mbps AES OFF
      SIG1：27 SIG2：22
      ber1：0.14% ber2：100.00%
      REC OFF No Storage
   2. RF indicates the center operating frequency, iyo BW indicates the working bandwidth.
      QPSK is the modulation mode, CR is the convolutional code rate, and GI is the guard interval.
      AIR 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, iyo SIG2 refers to the other antenna.
      Ber1 refers to the BER error rate near the HDMI port antenna, iyo ber2 refers to another antenna.
      REC OFF means no video storage
8. When the wireless receiving signal is interrupted or weak, the output video screen will be interrupted (the re-received signal screen will be automatically restored), and display: Disconnected, no signal
9. 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. If the TF card is not inserted, it is recorded to the USB flash drive. If they are not inserted, they will not be recorded.
10. Link indicator: The wireless receiving link working status indicator lights up after the system is started and blinks when the receiving signal is normal.
11. REC indicator: The video recording indicator will flash at the low frequency when recording video, otherwise the high frequency will flash.
12. PWR indicator: Tilmaamaha Awoodda.
13. CFG serial port: Parameter configuration Serial port, you can configure wireless receiving related parameters, such as center working frequency, bandwidth wireless, decryption password, iwm. Vcan provides a matching parameter configuration panel SconB to facilitate user parameter setting.
14. Data serial port: Transparent data transmission serial port. The serial port data of the transmitter can be wirelessly transmitted to the receiver and output from the serial port.
15. TF card interface: Used for software upgrade maintenance or for storing video.
