The serial number may contain as many as six uppercase or lowercase ASCII
alphanumeric characters.
Note:
The factory-assigned serial number of the reader contains seven characters. However, to
maintain backward compatibility, the reader software allows only six characters to be entered.
When setting the serial number, skip the fourth (middle) character of the seven-character number
shown on the reader product label.
Note:
Once assigned, the serial number is preserved during power-down and the loading of default
parameters.
Reader response:
Done
696S...S Store Hardware Configuration String (Factory Default)
#696S...S
stores hardware configuration information into reader memory. The hardware
configuration string is assigned according to the following format:
696S...S
where
S...S
is the hardware configuration string that may contain as many as 20 uppercase or
lowercase ASCII alphanumeric characters.
Note:
Once assigned, configuration information is preserved during power-down and the loading of
default parameters.
Reader response:
#Done
697 Set User-Programmable Group Select Equals (GSE) Filter
#697
sets the user-programmable GSE filter. The command string is assigned according to
the following format:
697 MM AA DDDDDDDDDDDDDDDD
where
MM =
The tag uses this mask to determine which of the eight Comparison Data bytes are to
be compared for the Group Select filter.
AA
=
This field is used by the tag to determine the start address in the tag memory for the
comparison data.
DD…DD =
Comparison Data: an 8-byte field (16 characters) used by the tag as the comparison
data for the Group Select filter. The tag compares the data in this field to data in tag
memory beginning at the Start Address to determine if the tag will respond to a reader
Group Select request. Only the bytes having the corresponding bit set in the GSE Mask
is used for this comparison.
As an example, to configure a reader to have only tags with data in byte locations 10, 12,
and 15 (decimal) with hexadecimal values “00,” “01,” and “02,” the following command is
used:
#697 A4 0A 0005014202024133
