3.4 Power Connection (for all models)
The A9230-D series RFID readers receive DC power (+5V) through its USB connector.
Therefore, the USB cable must be used to connect either to a +5V DC source, a PC, or
other host device which can provide +5V DC power through the USB connection. For
USB host interface models, only the USB cable needs to be connected. For all other
models, both the host interface cable and the USB cable must be connected for proper
operation.
