Failure cause analysis:

1. Control whether the host is turned on

2. Is the communication line plugged in properly?

3. Whether the sending card has been inserted

4. Are the data cables between the multimedia card, capture card, and sending card connected properly?

5. The JP1 or JP2 switch position of the receiving card is incorrect.

Failure analysis and processing:

• Turn on the console

• Plug in the communication cable

• Reinsert the sending card

• Connect the data cable between the multimedia card, capture card and sending card.

• Adjust the JP1 and JP2 switch positions
