Barcodes are read by each RFID Reader Writer or barcode reader when the trigger is
input. The read data is sent to the Link Unit, and held in the Link Unit's internal buffer.
Normal Protocol (Polling)
After the host sends sequential commands to each Link Unit, the polling command
is used to get the sequential results from each Link Unit.
