All other values are reserved, and reader will return a parameter error status in the response frame if
other value is delivered in this field.
ScanTime (optional parameter): 1 byte, the inventory time configuration for the current inventory.
Reader will set the maximum operation time as ScanTime*100ms.
NOTE:
1. Target, Ant and ScanTime are optional parameters, all three parameters must be delivered in one
command frame. Reader will apply default setting for these parameter, until all three parameters
setting are being properly deliver from host, the new settings will then become effective for
following inventory.

After inventory, deliver statistic data of the last inventory process
Ant: indicates which antenna had inquired a tag. For example, 0x04 is 0000 0100 in binary, this
indicates Antenna 3 had inquired this specific tag. For 0x08, it is 0000 1000 in binary, then it
indicates Antenna 4 had inquired tag information.
ReadRate: tag identification rate for the current inventory (time of successful identification / sec), a
tag being indentified multiple times will also increase the time of successful identification.
TotalCount: the total amount of tag detected in the current inventory, a tag being accessed multiple
times will also increase the total amount.
