FAQ

  1. The PWR indicator light is off
    Please check the power supply whether is working, or if the power supply meets the device of the standard (DC 12V/1A).
  2. The PWR indicator light is flashing
    Device fault. Need to contact the vendor for repairing.
  3. LOCK indicator light is flashing display output blue screen/black screen
    SDI input signal is not normal (not locked), please check the connection of SDI signal whether is correct, please special pay attention that the SDI input signal cannot be connect to SDI out interface.
  4. RUN indicator light is off
    Please check the cable of HDMI/VGA whether is connected to displayer correctly, or whether the displayer is turn on. If the connection is normal, then it’s the device fault.
  5. RUN indicator light is on/flashing no any display output
    Try reset the video input interface (HDMI or VGA or CVBS), or turn on/off HDMI/VGA displayer. If the problem still exits, press the POWER button on the remote control, wait for about one second, press the POWER button (restore factory settings) once again.
  6. SDI output video format and HDMI & VGA & CVBS input video format is inconsistent
    See conversion rules describe in section III, our converter is not a simple converter, which built-in the professional graphic processing chip, which support video scaling & de-interlace & frame rate & format conversion & color enhancement to satisfy the request of user. The various output formats can option by remote control to suit in different application place.
    If you want to set fixed SDI output format, you can try to set the SDI output format by remote controller. However, this may cause the receiving of the device does not support the SDI format and cannot display images. When the converter comes out the irregularities, press the POWER button on the remote control, wait about 1 second, press the POWER button again to restore factory settings.
  7. SDI no signal
    Under normal situations, the converter will output an SDI signal anyway! Even if there is no input signal, and will output a blue/black screen signal. If no SDI signal and nothing displayed on the monitor situation, please check your connection of cables, cable’s quality.
  8. SDI Output no sound
    Please check the HDMI signal whether with audio source; or check the remote control menu settings, whether is selecting the correct audio signal source. If you select the audio signal source is derived from Line-In, make sure that the audio Line-In line is connected properly.
  9. HDMI input, audio with noise
    Please check the HDMI cable’s quality at first. Most users have such problems, because of the quality problems of HDMI cable.
  10. HDMI input, audio is intermittent or not normal
    Audio of SDI signal standard requirement 48KHz sample, two-channel audio. Although the DDC to HDMI of converter data constraints, but part of the HDMI signal output (such as a video player, DVD player, etc) does not strictly follow the HDMI DDC specification, then output non-48KHz sampling audio. Try setup your HDMI signal source (if allow) and if this is not resolved, try to connect the Line In analog audio to the converter interface, and via the remote control menu to select the audio signal is Line In.
  11. Images has grainy/highlight/black line
    Please check the HDMI & VGA & CVBS connection cables, if necessary, replace the excellent quality cable.
  12. SDI signal transmission distance is not achieve the standard
    SDI signal transmission distance is affected by many limitations: (a) the quality of original SDI signal (the eye pattern &amplitude& timing jitter & alignment jitter of SDI signal can be analyzed via the signal analyzer, detect the signal whether follow the standard); (b) the quality of transmission coax; (c) the ability of SDI receiver in signal equalization, clock recovery, and so on. SDI output interface of our converter has professional design and testing, using SYV-75-5-1C cables meet the national standard testing, 1.485G HD-SDI signals can be transmitted 200 meters, 2.97/3G-SDI signal can transmit 100 meters. However, the actual transmission distance will be a little different due to the signal, coax, and environment is different.
  13. JUST A DEMO PRODUCT ONLY! on the output screen
    This product has encryption protection. The converter will appear above tips when encryption chip is damaged or the software is illegally copied. Please ensure that your product is purchased through formal channels, or not unpick the product. Please contact the manufacturer or authorized dealer.
