2.7 Troubleshooting
The card reader does not respond after being installed.
If the card reader does not respond, it may be due to the power problem. Try these steps:
1. To verify the problem, remove the paper covered on the GV-AS200 module and check if
the power light of the card reader is ON.
2. If the card reader is connected over a long distance, use two additional resistors of 10K
ohms to solve the problem. Insert one resistor between D0 and 12V and insert the other
resistor between D1 and 12V.
