Q6: What is the administrator password in the host PC software settings?
A: No password is provided and you can just click “OK” to enter directly.
Q7: What possible reasons if the processor software shows that a serial port can not be connected? What can
indicate normal connection?
A: To have your computer control the video processor, you need to connect its instruction transmission line (i.e.,
serial port line).
If connection has failed, the reasons may be as follows.
①
COM Select Error – You need to click “OK” and click on the “Serial Port Enable” button;
②
Serial Port Occupied - Two or more software windows can not be opened at the same time;
③
The serial port line is damaged or not firmly connected;
④
The mainboard COM driver or the serial port is damaged.

will help you solve the problem as quickly as possible.
Sign of normal connection: It will pop up a dialog box “Software and Device Synchronized” and you just need
to click “OK” at this time.
Q8: The large-screen display is normal if the graphics card is directly connected with the transmitter card, but
after a video processor is connected, a black screen will appear.
A: See whether the transmitter card green indicator is flashing normally; if normal, it indicates that the processor has
output signal, and then the possible reasons may be as follows:
①
There’s something wrong with the signal source. You need to set up its copy mode while connecting the computer
graphics card, but if not, the graphics card DVI port will have no data output. Setup steps: Disconnect the video
processor power - Reconnect the cable from the graphics card to the video processor – The ATI graphics card will
read the copy mode automatically, but for an NVIDIA graphics card, you need to enter the graphics card control
center and set up multiple d double-window copy mode.
②
The connecting cable has failed. When the signal line interfaces contact poorly or the wires suffer from internal
failures, the led screen will have color bars, fuzzy dots and other abnormalities. Check carefully whether the signal
line pins are forced broken or inclined, etc. and replace the signal lines if necessary;
