Programming Tags in AutoMode
Programming functions are fully supported by the reader's Autonomous Mode of
operation. Using Autonomous Mode, the user can assign the reader the task of
programming, erasing, and locking tags. This is done by setting the AutoAction
attribute to the appropriate action, as described below.
Two of the AutoMode functions, "Program" and "Program and Lock" require
some additional values to be specified first, specifically the ProgramID and
ProgramPassCode.
ProgramID
9800 | 9780 | 8780 | 9640 |
9774
The ProgramID attribute is used in AutoMode when a program operation has
been selected as the AutoAction, such as "Program" or "Program and Lock". This
command allows the user to specify the first ID code to program into a tag. Once
a tag has been successfully programmed, the ID is incremented by one, ready
for the next tag to be programmed.
Value supplied must be an 8- or 12-byte tag ID.
The default ProgramID is 00 00 00 00 00 00 00 00.
