6.4.4 ABxS Command 07H: Read Tag Serial Number

DESCRIPTION

This command retrieves the eight-byte tag serial number.

DISCUSSION

Each controller tag has a unique serial number. This number cannot be changed and is not part of the

available data bytes. The tag serial number is returned in the LSB only, with the MSB as 00H.

Example

In this example, the LRP 2000 waits until a tag is in range and then reads the eight-byte serial number. The

ID is AC310200000104E0H (hexadecimal) in this example.

Field Remarks
