(paperless conference system, ultra-thin one lifter) Question 1: The signal has input and no output?
A: Please check whether the input and output cables of the device are in good condition, whether the cables that are soldered are tightly connected, and whether the signal cable is beyond the transmission distance range.
Question 2: The device button is invalid?
A: Please observe whether the LCD display of the device has the word "#". If there is a keyboard indicating that the device is locked, press CTRL+LOCK to unlock it.
Question 3: Is the color cast when the matrix is ​​output to the display device? Is there a ghosting or smearing outside the matrix output?
A: Check if the input and output lines are connected properly. Check whether the input and output lines are directly connected to the monitor for normal display or for the input and output lines that can be displayed normally. If the projector has ghosting, it is generally not a host problem. It may be that the projector is not properly adjusted or the wire quality is not up to standard. The corresponding buttons of the projector should be adjusted or replaced. There may be a tailing that may not be the quality of the wire or the connection is too long.
Question 4: Matrix infrared can not be controlled? (Paperless conference system, ultra-thin one lift)
1. The remote control is out of power, replace the battery;
  2. There is an obstacle between the remote control and the host or the control distance is remote;
  3. The infrared control function is locked and can be unlocked through the panel to enter the matrix menu;
  4, the remote control is broken;
  5. The matrix infrared receiver is faulty.
Question 5: The matrix panel cannot be controlled? (The panel button operation does not respond)
A: The matrix panel control function is locked and can be unlocked via the panel or remote control.
Question 6: The serial port cannot be controlled?
1. Check whether the communication port set by the control software corresponds to the serial port of the connected device;
  2. Check if the computer communication port is normal;
  3. Check if the serial line sequence corresponds to the matrix serial port.
Question 7: Matrix input and output signals can be switched, but there is no bb sound (beep)?
1. The buzzer is turned off and can be entered into the matrix menu;
  2. The internal buzzer of the main unit is broken.
Question 8: When the matrix is ​​switched, the buzzer sounds, the LCD screen has a corresponding change, but there is no corresponding projection output. (Paperless conference system, ultra-thin one lift)
Answer: Check whether there is any signal at the corresponding input and output terminals. It can be detected by multimeter or oscilloscope. If there is no signal, it may be that the wiring is broken or the connector is loose. Otherwise it may be a device failure.
Question 9: The power light is not lit, and the LCD has no display, and the operation does not respond.
A: Check if the fuse is blown; Check if the power plug is badly connected or the power cord is disconnected. B) Power failure.
Question 10: Matrix panel buttons, serial ports, and remote controls cannot be controlled?
A: The matrix is ​​faulty and returned to the factory for repair. (Paperless conference system, ultra-thin one lift)
